In GPRS network, a SGSN is typically implemented as a single node; in cisco-Alcatel joint development, it's split into Telecom part (T-node) and Datacom part (D-node). T-nodes and D-nodes are connected by two fast ethernets. A simple connectionless protocol called L2RLY is used to provide service of forwarding packet between T-unit and D-unit, flow control and defending against the failure of a FE subnet.
