Abstract:
1. A method of packet grooming and aggregation within an Ethernet over SONET/SDH system (EOS system), said method comprising: receiving a data packet tagged according to an encapsulation scheme and including a tag and a port or channel ID; providing an input client frame from said data packet to a header unit; extracting a search key including said port or channel ID and said tag from said input client frame via said header unit; correlating said search key via a lookup engine to a match in a flow database to determine flow context; modifying said input frame via a tag editor according to said flow context; buffering said input client frame via a flow FIFO; applying discard policies to said flow FIFO based on said flow context; and scheduling said input client frame via a scheduler of the flow FIFO for transmission into output channels according to output channel status and flow quality of service parameters, wherein said correlating step occurs in accordance with a combined ingress table and egress table in a bi-directional lookup manner, and further including the steps of:
