Abstract

Systems and methods of the present invention for maintaining network data distribution are provided. Network data may be distributed in such as manner as to allow a network session to weather interrupted communications between host and clients without significant loss of data. Embodiments of the present invention provide for one or more clients to serve as backup host(s) for the network session. When the other clients transmit data to the host, they may also transmit the data to one or more backup hosts if there are any indications of interrupted communication.

Claims

1. A method for maintaining network data distribution, the method comprising:

establishing connections between a host and a plurality of clients;

negotiating backup viability of a first client from the plurality of clients; and

transmitting host information to the first client, wherein the first client establishes connections to one or more other clients from the plurality of clients based on at least the host information, and the first client receives data from a second client from the plurality of clients if communication between the host and the second client is interrupted.
