Allocation adjustment in network domains

摘要

A network node in a resource reservation network includes a data receiver, a transmitter and a timing adjustment requester. The data receiver receives fixed size application protocol data units (APDUs) from an application at fixed intervals. The transmitter transmits data from the network node to the network within transmission opportunities (TXOPs) associated with a constant data service flow for the application specified associated with the application and the network node in a media access plan (MAP) generated by a network scheduler. The timing adjustment requester requests adjustments of the network scheduler to the timing of TXOPs associated with the constant data service flow in order to minimize a delay between the arrival of the APDUs and their transmittal to the network.

1. A network node in a resource reservation network having a domain master having a network scheduler, the node comprising:
a data receiver to receive fixed size application protocol data units (APDUs) from an application at fixed intervals; a transmitter to transmit data from said network node to said network within transmission opportunities (TXOPs) allocated to a constant data service flow for said application specified in a media access plan (MAP) generated by said network scheduler; and a timing adjustment requester to request from said scheduler shifting the timing of an existing allocation for subsequent said TXOPs allocated to said constant data service flow in order to minimize a delay between the arrival of said APDUs and their transmittal to said network, wherein said network node receives from said network scheduler an updated MAP with adjusted TXOP allocations.
