Research firm, Heavy Reading, defines “P-OTS as a platform that combines SONET/SDH, connection-oriented Ethernet, DWDM and, depending on where the platform is used within the network, also optical transport network

In my last post, I had explained that it would be bandwidth in-efficient to carry TDM over Ethernet/IP links; today I came across an interesting white paper by Heavy Reading

Let’s face it. As an operator, you are faced with a situation of deciding between circuit emulation over Ethernet and carrying TDM data as  pure TDM transport; what would be

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
