Abstract

Ethernet-over-SONET/SDH (EoS) with virtual concatenation is a popular approach for interconnecting geographically distant Ethernet segments using the SDH transport infrastructure. In this paper, we introduce a new concatenation technique, referred to as cross-virtual concatenation (CVC), which involves the concatenation of virtual channels (VCs) of hetrogenous capacities and can be implemented by a simple upgrade at SDH end nodes, thus utilizing the existing legacy SDH infrastructure. By employing CVC for EoS systems, we show that the SDH bandwidth can be harvested more efficiently than in conventional virtual concatenation. We later consider the routing problems associated with CVC connections, namely the connection establishment problem and the connection upgrade problem. We propose ILP and heuristic solutions to solve such problems. Simulations are conducted to evaluate the performance of the proposed heuristic and to demonstrate the advantages of employing CVC.
