CISCO-GTP-DIRECTOR-MIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

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). +==+ +===+ +====+ ==== +===+ +====+ +===+ |MS|--|BSS|--|SGSN|--|PLMN|--|GDM|--|GGSN|--Gi-|PDN| +==+ +===+ +====+ ==== +===+ +====+ +===+ | | | | +====+ | |___|GGSN|------Gi | +====+ | | | | +====+ +===+ |_____|GGSN|--Gi-|PDN| +====+ +===+ 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 ).
