Abstract: Systems and methods are described for jointly optimizing communications in a multi-user network to maximize the weighted sum-rate of its data links. For example, embodiments seek to maximize overall link transmit rates, while minimizing link interference and/or noise in general multi-in multi-out (MIMO) interference networks having multiple interfering data links, each with one or more antennas at the transmitter and receiver. Novel algorithmic approaches, including an “iterative minimax” approach and a “dual link” approach, are described for solving the weighted sum-rate maximization in a manner that converges quickly and reliably on an optimal point. Some embodiments implement these approaches in a centralized transmission controller, while others implement these approaches in a distributed fashion.

Abstract: A method and corresponding device for determining forwarding rule for data packet in Virtual Private LAN Service with Provider Backbone Bridge (PBB-VPLS) network are disclosed. In the method, a value in a backbone service instance identifier (I-SID) field of the received data packet is firstly examined, then a virtual split horizon group corresponding to the data packets is determined based on the I-SID value, wherein the virtual split horizon group defines a forwarding rule for the data packets between different pseudo wire ports of the PBB-VPLS network. With the dynamic split horizon group, the method dynamically adapts to different forwarding rules for multiple I-VPLS instances with different tree topologies, and is capable of supporting multiple I-VPLS instances with different root sites and tree topologies in one B-VPLS instance, thereby ensuring the stability of the backbone network and reducing the network operation cost.
