ABSTRACT:
A cable modem link layer bridge includes a downstream forwarding task and an upstream forwarding task. The downstream forwarding task is structured to receive a first message from a cable network and forward the first message to a customer premises equipment (CPE). The upstream forwarding task is structured to receive a second message from the CPE and forward the second message to the cable network, the upstream and downstream forwarding tasks being multitasked such that the second message is forwarded by the upstream forward task while the first message is being forwarded by the downstream forwarding task.
