DESCRIPTION
|
|
"This MIB module defines objects that are used to
|
|
manage GTP Director Module.
|
|
|
|
In the GPRS network, the APN is the identifier that
|
|
specifies where the user is connecting. The APN
|
|
identifies whether the network is a corporate network
|
|
or a service provider network. The APN comprises of
|
|
two parts, the network id and the operator id.
|
|
|
|
The Single Access point feature enables the
|
|
service provider to add new access-points to the GGSN
|
|
without having to provision the HLR. The requests are
|
|
sent by the SGSN to the same virtual APN. A virtual
|
|
APN is not associated with any actual physical
|
|
network. The GGSN processes the request and forwards
|
|
the packet to the appropriate access-point that is
|
|
specified in the PCO. The Single APN feature is
|
|
supported only in Cisco GGSNs.
|
|
|
|
The purpose of the GTP-Director is to provide a
|
|
mechanism for service providers using non-Cisco GGSN
|
|
to use the Single APN feature. This would enable the
|
|
service providers to add access-point to the network
|
|
without having to provision the HLR. This will be
|
|
transparent to the SGSN. The mobile user initiates
|
|
a connection request to the SGSN. The access-point
|
|
name specified in the request is the virtual APN.
|
|
The GTP-Director would resolve the access-point name
|
|
and forward the request to the appropriate
|
|
GGSN (real GGSN).

|
The GTP-Director also provides load balancing across
|
|
GGSNs. The GTP-Director uses the round-robin
|
|
mechanism for providing load balancing. The
|
|
Cisco GGSNs may use the GTP-Director, but is not
|
|
necessary as they can use IOS-SLB ( Server Load
|
|
Balancing ).

occurs before it has expired.
