OC-192c/STM-64c and 10 Gigabit Ethernet WAN PHY

The introduction of 10 Gigabit Ethernet (10 GbE) WAN PHY into the IP/Ethernet networking community has led to confusion over the applicability between 10 GbE WAN PHY and OC-192c/STM-64 interfaces. Both of these interfaces support transmission at 9.6 Gbps, support SONET/SDH framing, and can be connected to SONET/SDH ADM or...

Detecting Configuration Errors in Operational SONET/SDH Networks

Large operational SONET/SDH networks have a significant amount of incorrectly configured equipment that affects network reliability and performance. These configuration errors cause latent errors and are hard to detect because they are dormant until another error triggers them. The traditional solution to detect configuration errors is to collect up-to-date inventory...

Testing Ethernet Over SONET/SDH

Data traffic levels continue to increase. As a result, there is a desire to optimize transport networks originally designed for voice to accommodate this traffic. The majority of metro and long-haul networks are based on SONET and SDH, as these protocols carry fixed-bandwidth circuit-switched voice very effectively. Ethernet over SONET/SDH...

Differential Delay Aware Routing for Ethernet Over SONET/SDH

The Virtual Concatenation protocol in SONET/SDH has ushered in a novel routing paradigm that enables a circuit to be "Split" and routed over multiple paths. However, this diverse routing causes differential delay among the paths which can impact service if not accounted for in the routing. This paper introduces the...
