In a communication system comprising a link layer device connectable to one or more physical layer devices, the link layer device is configured using an efficient shared architecture for processing data associated with a plurality of links including at least one ingress link and at least one egress link. The link layer device comprises an ingress data clock processor configured to generate an ingress clock signal for processing data associated with said at least one ingress link, an egress data clock processor configured to generate an egress clock signal for processing data associated with said at least one egress link, and a control and configuration unit shared by the ingress data clock processor and the egress data clock processor. Another aspect of the invention relates to a buffer adaptive processor that in an illustrative embodiment limits clock variability in the presence of cell delay variation or cell loss.
