Optimized Routing within an Ericsson Node - Routing procedures in an Ericsson SGSN

Abstract

In a specific Ericsson telecom equipment (SGSN) there are application boards and router boards. When the routers can not communicate directly with each other, a handover process between them can cause packet loss and unnecessary use of the internal network. This thesis presents a solution to this problem, using routing tables and feedback from routers to applications. The proposed solution is implemented into the node's source code. Performed tests show that the packet loss decrease dramatically and with that, the backplane is used more effectively.
