This paper considers the problem of minimizing the differential delay in a virtually concatenated Ethernet over SONET (EoS) system by suitable path selection. The Link Capacity Adjustment Scheme (LCAS) enables network service providers to dynamically add STS-n channels to or drop them from a Virtually Concatenated Group (VCG). A new STS-n channel can be added to the VCG provided that the differential delay between the new STS-n channel and the existing STS-n channels in the VCG is within a certain bound that reflects the available memory buffer supported by the EoS system.
