Abstract
A system and an algorithm in a mobile core network to distribute the data load across multiple data processing entities. The system is seen as having one data plane entity to the external entities like routers; hence the system can scale without needing to update the external nodes. In general when a data plane processing entity is added or removed, a new distribution rule is provided to the remaining data plane processing entities. Only after some number of sessions have been migrated does the new distribution get provided to the data distribution entities. This delay allows sufficient sessions to be migrated to minimize the overall number of packets that have to be forwarded for processing. This benefit can be maximized by taking advantage of cellular network's idle mode behavior and by migrating the sessions while they are in idle mode.
