EPG- Evolved Packet Gateway


The EPG combines the GGSN, SGW and PGW functions in one physical node. In addition, the evolved platform adaptation layer supports the EPG application running on both operating systems: Junos OS (the OS of Juniper M series routers) and IPOS (the OS of Smart Services Router), 
The EPG is available on different hardware platforms:
·         Juniper (M320, M120)
·         Smart Services Router (SSR 8020)


The EPG based on Juniper hardware is simply called EPG on Juniper and the EPG based on SSR hardware is respectively called EPG on SSR. In the EIN documents, these terms are used to distinguish between these hardware platforms. If the hardware platform does not matter, the EPG term covers all possible EPG configurations.
The EPG on SSR has an increased capacity, up to 10 times greater than the EPG on Juniper. Therefore, the EPG on SSR has a big impact on the PS core network, and this needs to be sustained in terms of capacity from the other PS network elements and transmission systems.

The EPG on SSR is not a product designed only for high capacity networks. Its scalable configuration suits it perfectly for small and medium networks with potential for further extensions.
The EPG can be ordered and deployed in the following deployment modes for single and combined functions:
·         GGSN only functionality
·         PGW only functionality
·         SGW only functionality (applicable only to EPG on SSR)
·         Combined SGW and PGW
·         Combined GGSN and SGW and PGW
