Method and system for optimized load balancing across distributed data plane processing entities for mobile core network
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.
