SDN, big data, and the self-optimizing network


October 23, 2013








SDN (software-defined networking) gains more mind share every day. The concept of reinventing networking to better match today's applications and infrastructures is a tantalizing goal, but clearly not without its challenges.


Michael Bushong has been around the SDN space for some time, having spent years leading SDN efforts at Juniper Networks. Bushong is currently working at SDN vendor Plexxi, and in this week's New Tech Forum, he takes a close look at what SDN promises -- and what questions need to be answered in order to truly reinvent the network as we know it. For that goal to be realized, says Bushong, SDN and big data must go hand in hand. -- Paul Venezia


Big data and SDN: Closing the loop
The networking industry has reached an inflection point. With cloud as the backdrop, SDN and big data are poised to converge in a way that will redefine how data centers function. As with all changes of this magnitude, the reality lies not in the big concepts but in the details of how these two technology forces come together. Those who understand the nuances will be in the best position to exploit the new technology -- and provide new points of leverage for data center architects.


Why we need SDN
To understand how SDN and big data will come together, you need to get to the heart of why SDN is hot right now. While much of the emphasis has been on the supporting protocols like OpenFlow, the reality is that SDN is larger than the technologies it comprises. SDN is really an industry reaction to an ongoing pain point in networking.


Today, provisioning and managing a network is a needlessly manual chore. So long as the surrounding infrastructure and applications using that infrastructure are stable and relatively unchanging, that pain is noticeable, but not crippling. But the rise of virtualization in compute and storage arenas has fostered enough workload portability to expose networking's contribution to IT pain.


The energy behind SDN exists because of the potential to alleviate that pain. But how does that work?


The most basic tenet behind SDN is the separation of control and forwarding. By centralizing control, the network can be treated as a unified resource. With a global view, the SDN controller can use the entire network to service application workloads. Conceptually, this is not unlike global traffic-monitoring solutions in cities today. With a citywide understanding of traffic patterns, control centers can use tools like metering lights and adjustable tolls to control the flow of traffic.

Top TV satirist back on air in a changed Egypt


CAIRO (AP) — "Welcome to The Program!" Every week Egyptians obsessively tuned in to hear that slogan and watch groundbreaking TV political satirist Bassem Youssef flay their politicians. Some loved his biting humor, others were infuriated, but no one could ignore it. For four months, they've gone without him, his show kept off the air by turmoil surrounding the country's coup.

Now the man known as "Egypt's Jon Stewart" is back, returning to the air Friday night in a country radically different from four months ago.

When Youssef's final show of last season aired, the president was Islamist Mohammed Morsi — Youssef's favorite target. The satirist mocked him and his Islamist supporters mercilessly week after week for mixing religion and politics and for botching the governing of the country. Soon after the last show, massive protests began against Morsi, paving the way for the military to remove him.

Since then, divisions have grown deeper and hatreds stronger. Hundreds have been killed in crackdowns on protesters demanding Morsi's reinstatement. Attacks by Islamic extremists have increased. A nationalist, pro-military fervor is gripping the country, leaving little tolerance among the public or officials for criticism of the new leadership, with military chief Gen. Abdel-Fattah el-Sissi lionized as a hero.

So the question hanging over Friday's episode of "El-Bernameg" — Arabic for "The Program": Will Youssef mock the military-backed leadership and its supporters as sharply as he did Morsi and the Islamists?

Doing so could anger Youssef's mainly liberal fan base, who adored the way he excoriated Islamists and who now largely support the military. But if he avoids it and focuses his jokes against Islamists, he could appear to be caving in to pressure. Morsi supporters — some of whom "hate-watched" Youssef as obsessively as his fans did — are already predicting the 39-year-old satirist will sell out.

In an article Tuesday, Youssef took up the challenge, criticizing the intimidating atmosphere.

"I admit things are much harder now," Youssef wrote in his weekly article in Al-Shorouk. "Not only because the raw material coming from religious stations or from Morsi has diminished," he quipped, referring to the rich vein of folly from Islamists he often mined for jokes — "but because the general mood is different."

"In reality, there is no tolerance on the Brotherhood side or among those who call themselves liberals. Everyone is looking for a pharaoh that suits them," he wrote.

He said military supporters tell him, "Don't talk about el-Sissi" — "even though they were the same ones waiting for me to talk about Morsi."

He noted that under Morsi's year-long presidency, Islamist critics sent him to the prosecution office for questioning on possible charges of insulting the presidency. "I may be visiting (it) again soon at the hands of other people, who allegedly love freedom dearly — when it works in their favor," he jabbed.

Most of all, he pointed to the difficulty of joking amid tragedy. "How do we come up with a comedy program when the talk all day is about blood?" he wrote. "When people live in fear, terror, hate and anger, no one listens to reason, let alone satire."

The surgeon-turned-comedian's form "Daily Show"-style program brought an entirely new type of political satire to Egypt. He began with short, independently made YouTube episodes during the 2011 uprising that toppled autocrat Hosni Mubarak. His show was picked up by a TV station popular among young revolutionaries. As his star rose, he moved to another station, CBC, seen as stacked by former supporters of Mubarak.

Many thought Youssef would follow the station's conservative line. But he turned his jokes against his own station, mocking its claims of revolutionary credentials. With sky-high ratings bringing advertising cash, CBC was not about to drop him.

But his biggest target was the Islamist elite that rose to power in post-Mubarak elections — excoriating them so sharply that some credit him for fueling the tidal wave of protests against Morsi. In fast-paced jokes, Youssef lampooned Morsi's clumsy speeches and gestures. He played clips from Islamist TV stations to expose hypocrisy in their mix of religion and politics. He fact-checked the president. One episode in which he played video clips showing 2010 remarks by Morsi, calling Zionists "pigs," caused a brief diplomatic tiff with Washington.

In reply, Islamist lawyers tried to sue him for "corrupting morals" or "violating religious principles" and prompted the arrest warrant for "insulting the presidency." He was questioned by prosecutors and released without charges.

Naila Hamdy, a journalism professor at the American University in Cairo, said Youssef might go after the military-backed civilian government or satirize out-of-control pro-military fervor. But mocking the military directly is harder, given the public mood. "It is a very highly mobilized nationalist feeling in the country. Even Bassem Youssef would not want to go against that."

Social media have been buzzing. A Twitter hashtag of "#Joy" was started by fans for his return.

"Will he be like all the other media personalities or will he stand out?" tweeted one fan, referring to other media's unquestioning backing of the military.

One pro-Morsi protester, Mahmoud Mohammed said Friday he always watched Youssef "to know what the other camp is saying."

And he's convinced the comedian will stick to knocking Islamists and avoid the military. "The government repression is too heavy."

2 shot at Nat'l Guard armory; gunman in custody

(AP) — A member of the National Guard opened fire at an armory outside a U.S. Navy base in Tennessee, wounding two soldiers before being subdued and disarmed by others soldiers, officials said Thursday.

Millington Police Chief Rita Stanback said the shooter was apprehended Thursday by other National Guard members, and that he did not have the small handgun used in the shooting in his possession by the time officers arrived. Stanback said two National Guard members were shot, one in the foot and one in the leg.

"I'm sure there could have been more injury if they hadn't taken him into custody," Stanback said.

The two people shot were taken to a hospital. Stanback said at a news conference that their conditions were not immediately known, though the Navy said on its official Twitter account that neither had life-threatening injuries.

The shooter was a recruiter who had been relieved of duty, said a law enforcement official briefed on the developments. The official was not authorized to discuss the investigation publicly and spoke on condition of anonymity.

Stanback said the shooting happened inside an armory building just outside Naval Support Activity Mid-South. There are more than 7,500 military, civilian and contract personnel working on the base, according to the facility's official website. The facility is home to human resources operations and serves as headquarters to the Navy Personnel Command, Navy Recruiting Command, the Navy Manpower Analysis Center and the U.S. Army Corps of Engineers Finance Center.

The Navy said the base was briefly placed on lockdown as a precaution, though the lockdown was lifted in the afternoon.

On Thursday afternoon, yellow crime scene tape remained around the front of the building where the shooting happened. Law enforcement had blocked off streets with access to the armory, which is across the street from the army base.

Arrest ends CA shootout that wounded 6 officers


ROSEVILLE, Calif. (AP) — Police said a wanted parolee fired first in a shootout that left six officers injured and led to an hours-long standoff in a suburban Sacramento city before he surrendered.

Roseville police spokesman Lt. Cal Walstad said that one officer with a jaw wound and a federal agent shot in the leg remain hospitalized Saturday in serious condition. Four other Roseville officers injured by shrapnel were treated and released.

The suspect in the violent confrontation is a validated gang member with a criminal record that includes assault and carjacking. Samuel Nathan Duran, 32, was taken to the Placer County jail Saturday after being treated for scrapes and cuts after surrendering just after midnight.

"Last night our community experienced what can happen in any when a violent wanted felon is completely committed to not going back to jail," Police Chief Daniel Hahn said Saturday.

Duran was being held on a parole violation, but Hahn said he expected multiple charges of attempted murder would be added.

Duran's aunt told the Sacramento Bee they did not believe he fired the shots that struck the federal agent and that the police response to the incident was excessive.

"This is out of proportion — (Duran's) a parolee," Donna Sandoval said. "My nephew isn't a murderer for all this ... to happen. They shot first at my house."

State corrections officials told The Associated Press that Duran has a record stretching back to at least 2002, when he was convicted of possessing a controlled substance. In 2009, he was sentenced to four years for assault with a deadly weapon, resisting arrest and attempted carjacking.

Records show he was paroled last in April, but that the parole was revoked in July.

Hahn said officers on an unrelated gang enforcement mission recognized Duran as a wanted parolee when they saw him riding a bike Friday afternoon.

A federal agent embedded with the Roseville police department tried to chase Duran on foot, but was shot in the leg. Officials said Duran was armed with a handgun but wouldn't specify the type.

Hahn asserted that Duran opened fire when he was confronted.

Duran quickly holed up in a nearby house, and a mother and child inside escaped out a side door.

The shootout sparked panic and chaos in the typically quiet middle class suburb of about 120,000 that is 20 miles northeast of the state capitol. Walstad described multiple shooting sites as the suspect tried to escape a swarm of law enforcement agents, and reporters on the scene described hearing several volleys of gunfire.

As officers tried to capture the suspect before his surrender, helicopters were circling overhead and armored vehicles and other police cars flocked to the area.

At least 15 homes were evacuated, and the area remained a crime scene Saturday, Walstad said.

U.S. Immigration and Customs Enforcement spokeswoman Virginia Kice said the Homeland Security Investigations agent was stable and in good spirits after being taken to Sutter Roseville Medical Center.

Touched: Afterscape

This is very much raw, unfiltered ideas about a possible setting I've been playing around with for the past year. It's somewhat of a fusion of multiple genres; very much like Shadow Run but not as advanced. Here's the lowdown.

Touched: Afterscape

All life on the surface of the planet had been told it's expiration date. We were going to die.

Some deep space sensors had managed to detect an incoming asteroid the size of Alaska. It would hit the east coast of what was the United States and unleash a massive shock-wave that would decimate the entire planet. It was surmised that it would likely create a tsunami that would flood most of the land, cause massive volcanic activity, and block out the sun with the resulting debris that would plunge the surface of the planet into another ice age.

People started making plans within the three months that it would take for oblivion to arrive. The International Space Agency was given every material, every worker, every consideration in order to find a way to survive. The ISA worked together with governments around the globe to create a ship that could deliver a nuclear payload and an international team of astronauts trained to drill into the asteroid and plant the payload. They would not be able to return.

As the team piloted the ship named 'Salvator' toward the asteroid many of the people on the ground, those of us normal and unable to assist with the Herculean effort, tried to live our lives. It took a week for the Salvator to get visual of the asteroid and many of us huddled around our televisions and radios and listened as the International Space Agency spoke with the astronauts on board.

As the Salvator neared the asteroid, most of the astronauts began to feel ill. As they set up the drills, an American man from somewhere in Florida threw up in his suit and made his way back to the shuttle. As he neared the door he fell over and stopped responding. Thirty minutes later another, a woman from Tokyo, Japan, complained about her visor fogging up and numbness. She simply stopped moving and floated away. At this point, the ISA told the astronauts to cease waiting for orders unless they needed help and to proceed as quickly as possible. Something was wrong.

By the time the nuclear payload was planted, almost five agonizing hours later, only two astronauts were still alive, a Russian man from Moscow and an American woman from New York City. As they sat in the shuttle and reflected on their work, a council of the astronaut's families and world leaders thanked them for everything they did, for what they had saved their home from. As both astronauts slowly faded, the ISA sent the order for detonation. The astronauts fell silent as they and the asteroid were subjected to a combined nuclear payload of over one thousand kilotons of explosive force.

As the light from the nuclear blast faded and most of the dust drifted away, the ISA was delighted to discover that the resulting pieces of the asteroid were now drifting apart. Celebrations erupted the world over. What we called the 'impact generation' was conceived that night, products of elation of good will.

The next day came news nobody wanted to hear. While most of the asteroid had dispersed, many of the resulting pieces were still on a crash course with the Earth. Two months later the remaining pieces of the asteroid crashed into the earth's surface, spread out and causing destruction and mayhem across the globe.

----------------------------------------------------------------------------------------------------------------------------------------------

While it was true that the resulting physical damage from the impact was lessened, there was an unforeseen side effect resulting from the physical makeup of the asteroid itself. It was nothing we as a civilization could have ever expected, but strangely something we've written about for centuries, millenniums even.

It contained crystals, emitting high doses of a strange radiation, what we've come to know as M-Radiation. What creatures didn't die from the impact, earth quakes, tsunamis, or extreme winters also had to contend with the M-Radiation ripping apart their nervous systems. I've estimated that about eighty percent of the humanity, if not most of life on earth's surface, died from the asteroids impact itself. A further fifteen percent then died from the M-Radiation. In short, of the approximately eight billion people on earth, only four-hundred million survived.

About a decade afterward, those who survived it all started to notice something. We became stronger and faster. We had mutated, re-written by the strange forces released by our oblivion. And those of us who would later investigate the remains of the asteroid came to understand them as the source of this strange radiation.

Many called it a miracle, some called it a conciliation prize. Some claimed it was given to us by their gods, others that some alien race had predicted what we would do and sent it to us to make us pure enough to interact with. After many years of trying to survive the savage environment around us, we noticed something else that was beyond odd. Some of us had stopped aging. For every one-million people, one of us never visibly went beyond the age of thirty. I was one of them.

Can you imagine that? Immortality. To be chosen by fate, luck, or the whim of some celestial being, and stop aging. All that time, all that possibility. It became a nightmare in the first few decades. Many were killed out of jealousy, bigotry, paranoia, exile, and guilt. Of course for every 'Touched' killed, there were twenty trusted with oral histories, teaching children of the past, operating Pre-Sunder Machinery. And it didn't stop with the generations left over from the old world, the children also were under the effect of the one in a million lottery.

After many years of Touched being exiled, one defended himself from a mob by throwing fire. Fire! With his bare hands! He was the worlds first wizard. I managed to talk with him after hearing about it and he had no idea what he was doing, he just managed to will a ball of force and heat into existence. He had lived long enough to have subconsciously learned to create a spell and use it. The practice spread like wildfire. At first it was only the Touched, but as they learned more they were able to pass on the teachings to the mortals and they too could perform what we thought to be Magic.

Life became much more interesting. Civilization exploded as 'Wizards' began to lean how to manipulate the strange energy known as M-Radiation and use it to stop rivers, plow fields, lift boulders, and quell fires. Nomads turned into villagers, villages turned into towns, towns turned into cities. Of course we couldn't stay peaceful, could we? The wars were destructive beyond compare. Imagine the destructive power of a cannon. Now imagine dropping pieces of a nearby mountain onto a cities defenses and tell me with one is more effective.

Of course the 'Wizards' pushed themselves to hard during the initial skirmishes. Those who were mortal simply died as their nervous systems became fried and the organs shut down. Those who were Touched suffered a much worse fate. They became deranged and savage, monsters in the skin of man with eyes black as pitch. We don't know exactly what happens, but whatever forces were keeping us from aging supported our bodies but not our minds. While the poor bastard's gray matters cooked their bodies became weapons without masters and struck out at everyone, save for other deranged.

There were less people throwing mountains at each other after that happened a few times, but it didn't stop the eternal war machine. Some people discovered what came to be called 'Sorcery' and the world became much more dangerous.

They were able to take people's souls, or what we called souls. More appropriately, it was the electrical energy generated by the human mind and, somehow, the consciousness of that human. And not just people, animals too. They could use this energy to imbue objects with arcane effects, ensnare the senses of the living, and even create armies of hypnotized warriors.

The fools, a world covered in mutated life and mostly unfit for humanity and all they could think about was making sure they had more than everyone else.

It's been almost two centuries since 'The Fall.' My life has taken me along a path that has been both dangerous and peaceful, destructive and productive. Today peace is the way of the world, but I have come to know of a plot that threatens that peace. Something is coming, I don't know what. I just hope that I and the people of the Afterscape are ready for it.
