What would you say if I told you that one of the most visited websites on the Internet enabled IPv6 connectivity to their site in the course of an afternoon for zero dollars using existing Cisco hardware? How about if I told you that the site was Facebook? Most people would assume I was joking or exaggerating. However, by using LISP, Cisco Certified Internetworking Expert Donn Lee pulled off this seemingly impossible feat and then presented a paper at the North American Network Operators Group (NANOG) about the experience. You can even watch the video here.
What is LISP?
Let’s start by understanding the problem that LISP solves. An IP address serves two distinct functions: It identifies the endpoint host, but also suggests the location because the high order bits identify the network on which the device is located. If you move a device from one subnet to another, the address has to change since the device location changes. The endpoint identification from the previous location gets lost when the device moves, unless some form of tunneling or mobility protocol is employed.
Finally it’s here. Cisco has been working on integrating the Media Services Interface (MSI) into the WebEx Meeting Client.
For those unfamiliar with the MSI, it’s an SDK developed to enable applications to interact with a Cisco Medianet. One of the long standing challenges IT organizations have faced has been to harmonize the needs of applications and endpoints with the network services required to meet those needs. It’s been a case of ships in the night as network administrators have done their best to deliver services while having limited interaction with the endpoints and applications that leverage those services. Asking endpoints and applications to consistently implement all the networking protocols to enable them to leverage the network has often led to mixed results; inconsistent or incomplete protocol stack implementations led to interoperability issues with the burden usually falling on the end customer.
“Wait a minute,” I hear you say, “Didn’t we already run out of IPv4 addresses?”
Yes, you have a good memory: The IPv4 address pool was exhausted in February 2011. The doomsayers and pundits all bemoaned the gloom and doom of the day, and experts gravely predicted the horrors of things to come. IT publications were filled with articles, Twitter exploded with witty remarks about the coming “ARPAgeddon,” and even the mainstream media ran semi-accurate sensationalist articles on the topic.
But then something funny happened. Nothing. The Internet kept working. IPv4 blocks continued to be handed out. The dust settled and most folks went happily about their business. How could this be so? Was it all a bunch of media hype and false alarms? No. February was really the early warning of the problems to come.
The announcement earlier this week focused on the Borderless Networks services with new capabilities for Centralized Policy, Unified Management and Automated Video and Voice. For more information on the announcement, see Marie Hattar’s blog.
Automated Video and Voice highlights the unique capabilities in the network infrastructure to simplify the deployment and optimize the network for video.
Because it is not a question of IF it is coming to Enterprise networks, but WHEN. As you can see from the chart from Forrester Research (Jan. 2011) the adoption for video applications and technologies is on the significant growth path because they are adding value for businesses.
Steven Boutelle, Vice President, Cisco Global Government Solutions Group would like to share some of the latest updates to the Internet Routing in Space (IRIS) program and provide an expert’s overview on where the satellite industry stands today. Watch Steven’s interview below!
To further assist in moving IRIS forward, TeleCommunications Systems, Inc. has been selected as an exclusive service provider. This is another milestone in the long-term collaboration between TCS and Cisco in an effort to move IRIS onward.
