Top 10 Reasons I think SDN Openflow will gain momentum
Predicting the future is often as easy as looking at the past, no crystal ball required.

As the debate of packet vs. circuit switched networks has clearly been won by the packet side of the house. Arguably the the increasing demands of service provider bandwidth for triple play …
MVPN Multicast with Multi-Protocol BGP MPLS VPN on Cisco IOS
Below assumes you have the basic MPLS transport setup. MVPN or multicast vpn is deployed on Cisco gear using Multicast Distribution Trees (MDT). This information is encapsulated in the MPBGP MPLS sessions to be distributed into label switch paths (LSPs) for forwarding. The following code will produce a basic functioning Cisco IOS MDT multicast environment. A tutorial for that can …
Death to the Firewall
The Firewall will die soon. Blackbox hardware just doesn’t make sense anymore. CPU is king when it comes to processing payload and that is commodity. SDN will put a nail in the custom hardware closed system soon enough. Until then, some musings on a project to collapse some functions into a router. Ironically, I can only collapse application processing into …

How to deploy MPLS VPN’s on Cisco gear
There is no easier way to simplify your enterprise routing and path isolation than implementing MPLS/VPNs RFC 4364. Label Distribution Protocol (LDP) is the transport method to insert a label into the header to be forwarded down the Label Switch Path (LSP) by the Label Switch Router (LSR) Most routers past the SOHO market support MPLS in hardware. On the …
