Instead of an evolution of existing transport standards, a revolution was necessary in order to enable additional data-related transport. Next Generation SDH/SONET provides a detailed description of the enablers of efficient data transport over any synchronous network. These include virtual concatenation (VCAT), the operation to provide more granularity, and the link capacity adjustment scheme (LCAS), an exte
