Distributed bandwidth control in a communication network

摘要

Network devices of a particular device class can implement a distributed bandwidth control (DBC) protocol to utilize resources of a communication network in accordance with a threshold amount of resources allocated for DBC device communication. A DBC device of a plurality of DBC devices can determine a transmission cost associated with a pending transmission and a total transmission cost associated with previous transmissions within a predetermined time interval associated with the plurality of DBC devices. If a sum of the transmission cost associated with the pending transmission and the total transmission cost associated with the one or more previous transmissions does not exceed a threshold transmission cost allocated for DBC device communication, the DBC device can initiate the pending transmission. Otherwise, the DBC device can delay the pending transmission.

1. A method for controlling bandwidth used by a first class of network devices in a communication network, the method comprising:
determining, at a network device of the first class of network devices, a previous transmission cost, the previous transmission cost associated with first previous transmissions initiated during a time interval by a first plurality of network devices of the first class, wherein
the communication network comprises the first plurality of network devices of the first class and a second plurality of network devices of a second class of network devices, andthe previous transmission cost is not associated with second previous transmissions initiated during the time interval by the second plurality of network devices; determining, at the network device, a threshold transmission cost based on a maximum bandwidth of the communication network that is allocated for the first class of network devices; and determining whether to transmit a pending transmission from the network device based, at least in part, on the previous transmission cost, the threshold transmission cost, and a pending transmission cost of the pending transmission.
