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.
