Posts about Packet Optical

As mentioned in my last post, data center interconnect (DCI) is a growing market for the entire optical value chain – from carriers to optical component suppliers. Standard OTN, DWDM, Carrier Ethernet or legacy SONET/SDH platforms alone cannot address the high-bandwidth, low-power, low-cost and high-density demands of DCI. As a result, many network equipment manufacturers (NEMs) have developed specific solutions to address it. Some of the most common solutions are described below ...

Continuing my exploration of next-generation Ethernet encapsulation technologies, in this post I look at MPLS-TP, TRILL and Provider Link State Bridging.  These technologies are all currently under development in ITU-T, IETF and IEEE.

MPLS-TP

Originally begun in ITU-T as T-MPLS, this project is now incorporated into the MPLS work of the IETF, and has become a set of extensions and simplifications to MPLS.  Multi-Protocol Label Switching is a well established, successful (but ageing) core network technology, and forms the basis of almost every major Carrier Ethernet transport network worldwide.
