TCO of MPLS-TP versus IP/MPLS

ACG Research has done an interesting TCO of MPLS-TP versus IP/MPLS showing there is a huge reduction of  Total Cost of Ownership (TCO) in MPLS-TP versus IP/MPLS.  The analysis was done in two environments: Native Packet transport  on MPLS-TP versus IP/MPLS  and second one using TDM/Packet mix on MPLS-TP versus Circuit emulation on IP/MPLS.  The platform used for  MPLS-TP […]

Cloud drives Carrier Ethernet !

Cloud is driving the Carrier Ethernet evolution. The MEF is serious about the evolution of Carrier Ethernet to meet the new demands of Cloud. The first and foremost would be to understand the elastic and dynamic demands of  Cloud which are pretty new to Carrier Ethernet scheme of things. MEF is trying to see how […]

FAQ about Software-defined networking (SDN)?

What is SDN? Software-defined networking (SDN) is an approach to networking in which control is separated from hardware ( control decoupled from forwarding plane) and given to a software application called a controller. What are the issues with today’s networks? Networks are static: Today’s networks are static; e.g introducing new switches or moving any network […]

How is MPLS-TP different from MPLS?

Given  the attention MPLS-TP has received in the industry, it is worthwhile to discuss how this technology is different from MPLS. So here is a listing of the differences between the two. 1. MANAGEMENT PLANE SETUP : LSPs in MPLS-TP can be setup without the use of control plane purely through the management plane. Quite […]

Is there a room for 100G Non Coherent Systems ?

The debate whether there is a market for 100G direct detection systems which are essentially Non Coherent is interesting. ADVA is on one side while the rest of industry on the other side. ADVA has been strongly advocating the need for 100G direct detection trasnponders that can cater to the need of what they call […]

Why using CE-VLAN ID Preservation matters in Carrier Ethernet?

Ideally VLAN ID Preservation should be preserved ( CE-VLAN ID = Yes). After all, why it should matter, changing VLAN IDs. Having same VLANs IDs make it operationally efficient for both operator and customer. Operator can trace the circuit well, so can the end customer by just knowing the VLAN IDs. Not to forget that […]
