System and method of traffic engineering in a software defined radio access network

摘要

An embodiment method of traffic engineering (TE) in a software defined radio access network (SD-RAN) includes determining, by a radio resource manager (RRM) at a wireless radio node, respective data rates for paths of a plurality of user equipments (UEs) wirelessly coupled to the wireless radio node. The RRM computes respective supported wireless rates for the paths of the plurality of UEs according to the respective data rates. The TE module receives respective allocated data rates for the paths of the plurality of UEs. The method also includes repeating the determining and the computing using the respective allocated data rates.

1. A method of traffic engineering (TE) in a network, comprising:
determining, by a radio resource manager (RRM) associated with a radio node, respective data rates for paths for a user equipment (UE) wirelessly coupled to the radio node, wherein the paths are between the UE and at least one source and pass through the radio node; computing, by the RRM, respective supported wireless rates for the paths according to the respective data rates; communicating, by the RRM, a supported wireless rate for the radio node to a TE module, wherein the supported wireless rate is a function of allocated traffic for the radio node, resources available at the radio node, and a spectral efficiency for a last wireless link of each path passing through the radio node; receiving, by the RRM, respective allocated data rates from the TE module; and repeating the computing according to the respective allocated data rates, the communicating, and the receiving.
