RSVP-TE and OSPF-TE extensions for GMPLS
Packets in MPLS are routed according to preconfigured label switched paths (LSPs). When packets are received, label lookup is performed from which it is identified to which LSP packets belong …
Essentials of ASON GMPLS
A presentation I created a while ago on basics of ASON GMPLS
Need for OSNR Testers for Pol Mux Modulations
OSNR ( Optical Signal to Noise Ratio) is a critical and important parameter in high speed DWDM links. If OSNR is not good it will seriously affect the distance reachability …
Soft Decision FEC ( SD FEC) versus Hard Decision FEC
As data rates increase beyond 10G, the requirements for OSNR become stringent. This is because the advanced modulation techniques used at higher bit rates require higher OSNR performance. Low OSNR …

Optical ASON or Electrical ASON!
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 …
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 …
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 …
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 …
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 …
