DESCRIPTION
|
|
"The MIB Module for managing the General Packet Radio
|
|
Service(GPRS) L2RLY related information on Servicing
|
|
GPRS Support Node(SGSN).
|
|
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.
