Abstract: Methods, systems and apparatus for suppressing redundancy in data transmission over networks are provided. Data segments are transmitted from a transmitting DPU to a receiving DPU. Initially, only signatures of the transmitted data segments are stored in a cache at the transmitting DPU. A data segment is stored in the cache only if it satisfies a redundancy-suppressing admission policy. Such a data segment is referred to as a redundant data segment. The redundant data segment is also stored in a cache at the receiving DPU. The transmitting DPU transmits the signatures of the redundant data segments to the receiving DPU, which then extracts the redundant data segments from its cache. Therefore, transmission of the redundant data segments is suppressed.

The lobby server can therefore reduce the bandwidth requirements and other operating demands on the application server. In addition, cross-application communications in real-time are facilitated through the lobby server concept. The multi-user application environment also provides a common data model for maintaining user information, such as for establishing a ladder ranking system in the online gaming context in which user achievements are recorded and shared among users and among the different game applications.
