Abstract
A service edge node for a multi-service access (MSA) network is provided. The service edge node includes a line card, numerous service cards, a control system, and switching fabric. The line card receives packets from an access network and removes framing information from the packets to provide raw packets. For each of the packets, the raw packet from the line card is directed to one of the service cards. In one embodiment, each of the service cards is dedicated to a particular logical channel, and the line card is configured to direct the packets based on the logical channels. In another embodiment, each of the service cards is dedicated to a particular traffic type, and the line card directs the raw packets to the service cards based on a preconfigured table from the control system defining the traffic type of each of the service cards.
