EPG on Juniper

          

Based on the Juniper M320 or M120 router, the EPG supports Physical Interface Cards (PICs) of the following types:

·         EPG services PIC: All EPG application software entities run on the EPG services PIC. These entities consist of Globe Session Controller (GSC), SGW Session Controller (SSC) and PGW Session Controller (PSC) for Control Plane, and Packet Processor (PP) and L2TP Packet Processor (TPP) for User Plane. The EPG services PIC is PB-GGSN3 Services PIC.

·         Network interface PIC: The network interface PIC provides 1GE or 10GE Ethernet connectivity for the EPG.

·         Standard services PIC: the standard services PIC runs platform-generic services, such as encapsulation and decapsulation of user payload into Generic Routing Encapsulation (GRE) or IPsec tunnels.

For EPG on Juniper, the following Network Interface PICs are supported:

·         2-Port Gigabit Ethernet  PIC

·         4-Port Gigabit Ethernet PIC

·         8-Port Gigabit Ethernet PIC

·         10-Port Gigabit Ethernet PIC

·         1-Port 10Gigabit Ethernet PIC

Note: The 10-Port Gigabit Ethernet PIC is only used by the EPG on M320 router.

Both M120 and M320 routers contain 4 and 8 Flexible PIC Concentrators (FPCs) respectively, which are used for the PIU container installation. In addition, two compact FPC (cFPC) slots are available on the M120 router for transport purposes only.

A single FPC or a cFPC slot in the EPG on M120 router has a maximum throughput of 10 Gbps full duplex.  A single FPC slot on the M320 router has a maximum throughput of 16 Gbps or 20 Gbps full duplex.
