NOTE Notice that we did not connect the Management1 interface of either vEOS instance to anything inside of GNS3. If you remember when we created the VMs, their first interface is a host-only adapter connected to the vboxnet in VirtualBox, so it’s automatically connected and there’s nothing additional we need to do there, but GNS3 doesn’t know that so it considers the interface disconnected, and that’s OK. That saves us from having to add our management server(s) to the topology and cluttering it up (Just imagine trying to have a nice clean-looking topology in GNS3 if you had to have a connection from every vEOS instance to the management server(s) ), which is distracting and ugly - we’re better than that. |
Edge provider networks, supporting DSL, voice, and other services to consumers and small businesses, tend to be more heavily bound by vendor specific equipment and hardware centric standards. These networks are built around the more closed telephone standards, rather than the more open internetworking standards, and hence they tend to be more expensive to operate and manage. As one friend said about a company that supplies this equipment, “they just print money.” The large edge providers, such as AT&T and Verizon, however, are not endless pools of money. These providers are in a squeeze between the content providers, who are taking large shares of revenue, and consumers, who are always looking for a lower price option for communications and new and interesting services.
If this seems like an area that’s ripe for virtualization to you, you’re not alone. AT&T has been working on a project called CORD for a few years in this area; they published a series of papers on the topic that make for interesting reading:
CloudApex functionality is key.

I was reading a trivia article the other day about the excellent movie Sex, Lies, & Videotape when a comment by the director, Stephen Soderbergh, caught my eye. The quote, from this article talks about how people use video as a way to distance ourselves from events. Soderbergh used it as a metaphor in a movie made in 1989. In today’s society, I think video is having this kind of impact on our careers and our discourse in a much bigger way.
People have become huge consumers of video. YouTube gets massive amounts of traffic. Devices have video recording capabilities built in. It’s not uncommon to see a GoPro camera attached to anything and everything and see people posting videos online of things that happen.
My son is a huge fan of videos about watching other people play video games. He’ll watch hours of video of someone playing a game and narrating the experience. When I tell him that he’s capable of playing the game himself he just tells me, “It’s not as fun that way Dad.” I, too, have noticed that a lot of things that would normally have been written down are Continue reading
