SCHEDULING IN A TWO-TIER NETWORK

摘要

A method, system and computer program product to schedule transmissions in a two-tier network are provided. In an example, the system includes a Data Over Cable Service Interface Specification (DOCSIS) scheduler configured to generate a MAP message to allocate bandwidth and a first instance in time to a cable modem to transmit data to a branch node. The system further includes a MAP message translator coupled to the DOCSIS scheduler and configured to determine a second instance in time at which data from the cable modem arrives at the branch node and generate a GATE message that grants the branch node bandwidth to transmit the data received from the cable modem at the second instance in time to a headend node.

1. A first node for scheduling upstream transmission times in a two-tier network, the first node comprising:
a scheduler configured to generate a first message to allocate bandwidth and a first instance in time for an end station to transmit data to a second node over a first medium of the two-tier network; and a message translator, coupled to the scheduler, configured to determine a second instance in time at which the data from the end station is to arrive at the second node and to generate a second message to allocate bandwidth to the second node to transmit the data received from the end station at the second instance in time to the first node over a second medium of the two-tier network.
