Cisco 100G DWDM– Works Anywhere Over Anything

By Greg Smith, Service Provider Marketing Manager, Cisco OK, so the title of this article isn’t totally accurate.

Cisco Fellow Mark Townsley: A Better Way to Deploy IPv6

We first talked about the Mapping of Address and Port (MAP) method to handle IPv4 exhaust and the transition to IPv6 last week. MAP is based on two IETF drafts currently in the process of standardization in draft-ietf-softwire-map (MAP-E) and draft-ietf-softwire-map-t (MAP-T). The real advantage with MAP is that it’s stateless and doesn’t require additional […]

Impact of Cisco Open Network Environment on SDN

For those of you familiar with the movie “This is Spinal Tap” the volume on SDN has been turned up to 11 for some time. However, too much of the sound is around the technology and not on the benefits to network operators. In fact, Cisco views SDN technology and our Open Network Environment (ONE) […]
