Virtualizing services within the network
When we launched the new ISR 4451-X at Cisco Live a few months back, one of the Big New Things we talked about was the Service Container architecture. Unless you were paying close attention to the 4451-X, you might have missed that whole thing. So what the heck is a Service Container?
To put it simply, a Service Container is a virtual machine running within the network itself. Instead of your typical server virtual machine, these VMs can be used to enhance the capabilities of the underlying network itself. Service Containers can add additional services, such as WAN Optimization, to the network. They can also enhance the capabilities of network devices by adding things like new programmable interfaces to the network. In some cases they can even be used to add impressive capabilities to the network from trusted third party developers.

Faster than the speed of light?
The biggest news to hit the world of physics recently was that neutrinos – “ethereal particles which pervade the universe but rarely interact with anything while they are doing so” – were shown in an experiment to have traveled faster than the speed of light. According to Einstein’s Theory of Relativity, this is impossible.
The experiment was conducted at CERN in September. Researchers shot neutrinos from Switzerland to Italy and measured the time it took for the neutrinos to arrive. The results showed they were arriving 60 nanoseconds earlier than light would have taken.
Is Einstein wrong? Are the laws of theoretical physics about to come crashing down around us? Um, not so fast (pun intended). Read More »
