400G is decided to be the next rate after 100G
The past year was hectic in terms of discussions regarding what could the next client rate for Ethernet and at the same time discussions were going on to decide the …
Don't miss the NFV mind map !
Well ! I have done all the efforts and made concepts simple through the Free NFV Mind Map. Get it now before I take it off. Plus get free updates to my blog.
The past year was hectic in terms of discussions regarding what could the next client rate for Ethernet and at the same time discussions were going on to decide the …
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 …
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 …
Soft Decision FEC ( SD FEC) versus Hard Decision FEC Read More »
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 …
