1. A scheduling unit for managing upstream message allocation in a communication network, comprising:
a processor configured to determine (i) a number of channels communicating in one direction stream of the communication network, and (ii) a grant interval duration of the communication network; and
a media access control (MAC) domain configured to (i) calculate a staggered allocation start time for each separate channel of the number of channels, and (ii) assign a different allocation start time, within the grant interval duration, to each separate channel,
wherein the grant interval duration comprises a first component indicating a next grant fulfillable time, a second component indicating a grant generation duration, and a third component indicating a grant advance duration,
wherein the communication network is configured according to a request-grant approach for transmissions in one direction stream,
wherein the request-grant approach includes a first request-grant loop latency and a second request-grant loop latency greater than the first request-grant loop latency,
wherein the first request-grant loop latency is based upon a sum of the second component and the third component, and
wherein the second request-grant loop latency is substantially equal to the grant interval duration.
