A presentation I created a while ago on basics of ASON GMPLS

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

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

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

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
