The T320 router provides 320-Gbps throughput and 385-Mpps forwarding rate and
supports 16 10-Gbps (OC192c/STM64 and 10-Gigabit Ethernet) ports, as well as
OC48c/STM16 for medium and large core networks, as well as for intermediate core
aggregation of access routers, peering, and metro Ethernet network applications,
such as those supported by Internet service providers (ISPs). It provides a
cost-effective migration path to an MPLS infrastructure. The T320 router supports
the JUNOS software, which provides router configuration and monitoring. (See
Figure 9.)
