Methods and apparatus for low latency operation in user space networking architectures. In one embodiment, an apparatus configured to enable low latency data transfer is disclosed. The exemplary embodiment provides a multiplexer that allocates a fixed portion of network bandwidth for low latency traffic. Low latency traffic is routed without the benefit of general-purpose packet processing. In one embodiment, network extensions for low latency operations are described. Specifically, an agent is described that enables low latency applications to negotiate for low latency access. In one embodiment, mechanisms for providing channel event notifications are described. Channel event notifications enable corrective action/packet processing by the low latency application. In one embodiment, mechanisms for providing interface advisory information are described. Interface advisory information may be provided asynchronously to assist in low latency operation.

According to some embodiments, a system for reducing bandwidth usage is disclosed. The system comprises a computer server that receives a request to initiate a multicast communication over a computer network and a computer readable medium comprising instructions that perform a method when executed by the centralized computer server. The method comprises initiating a multicast communication and assigning a unique identifier to the multicast communication. A set of messages associated with the unique identifier is received. If it is determined that a number of messages is greater than a pre-determined number of messages, determining a location of each of the users and grouping the users into a first group and into a second group where the first group are all located within a pre-defined radius based on a first determined location and the second group are all located within a pre-defined radius based on a second determined location.
