The debate still lingers on. When it comes to protection and re-routing on High speed links, what is the benefit of using Optical ASON versus Electrical ASON. The Optical ASON relates …
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 …
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 …
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 …
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 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 …
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 …
