Testing Ethernet Over SONET/SDH

Tags: circuit-switched, ethernet, applications, data

Overview 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 (EoS) optimizes transport networks to adapt to data and storage traffic, particularly for Ethernet and Fibre Channel applications. This paper will discuss the basic functions and test requirements of virtual concatenation (VCAT), which provides flexible bandwidth groupings for SONET/SDH; Link Capacity Adjustment Scheme (LCAS), which provides dynamic bandwidth settings; and Generic Framing Procedure (GFP), which provides a protocol-agnostic frame container.
