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...

Advanced Intelligence in Cisco Multiservice Transport Product

The advent of Reconfigurable Optical Add/Drop Multiplexer ROADM technology and mesh optical networks challenges the operating model for transport service providers, with SONET/SDH moving to the edge and even being replaced by Layer 2 and Layer 3 traffic. Traditional point-to-point Wavelength-Division Multiplexing WDM becomes complex all-optical networking, eliminating the need...

Efficient Transport of Storage and Ethernet Across Hybrid DWDM and SONET/SDH Networks

Proliferation of storage traffic due to disaster recovery and business continuance requirements, combined with the high cost associated with downtime or loss of data, justifies the need for interconnecting geographically dispersed data centers. At the same time, mission-critical applications such as e-business and customer relationship management, and emerging applications such...

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...

Next-Gen Sonet/SDH Chips

Much has happened in the development of next-generation Sonet/SDH systems in the past year. The big driver in this field is user demand for Ethernet-based services, which is growing rapidly around the world. In many cases, carriers will provide these services over existing Sonet/SDH infrastructure using multiservice provisioning platforms boasting...

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...
