System Overview; Benefits Of The Ptx10008 Router - Juniper PTX10008 Hardware Manual

The Juniper Networks PTX10000 line of Packet Transport Routers bring physical and virtual innovations
to the service provider core network. These next-generation routers help network operators achieve their
business goals while effectively handling current and future traffic demands. For more information, see
the following topics:

System Overview

The PTX10008 router provides 3.0 terabits per second (Tbps) per slot fabric capacity for service providers
and cloud operators. The PTX10008 router for the core supports the PTX10K-LC1101, PTX10K-LC1102,
PTX10K-LC1104, and PTX10K-LC1105 line cards.
The PTX10008 router provides an opportunity for the cloud and data center operators for a smooth
transition from 10-Gigabit Ethernet and 40-Gigabit networks to 100-Gigabit Ethernet high-performance
networks. This high-performance, 13 rack unit (13 U) modular chassis can provide 24 Tbps of throughput
and 16 Bpps of forwarding capacity. The PTX10008 router has eight slots for the line cards that can support
a maximum of 1152 10-Gigabit Ethernet ports, 288 40-Gigabit Ethernet ports, or 240 100-Gigabit Ethernet
ports.
The PTX10008 router can be deployed in the core as a label-switching router (LSR).
The PTX10008 (IP core) router is available in both base and redundant configurations for both AC and DC
operation. All systems feature front-to-back airflow. This airflow is also know as airflow out (AFO).

Benefits of the PTX10008 Router

System capacity—The PTX10008 Packet Transport Router has a 13-U form factor and supports 24 Tbps
per chassis or 72 Tbps per standard 19-in. telecommunications rack, with support for up to 240
100-Gigabit Ethernet ports, 288 40-Gigabit Ethernet ports, or 1152 10-Gigabit Ethernet ports in a single
chassis.
Full-scale IP and MPLS routing—PTX10008 delivers the distributed peering scale of 2.9 million forwarding
information bases (FIBs) and 30 million routing information bases (RIBs) (also known as forwarding tables
and routing tables, respectively), 3000 OSPF adjacencies, and 4000 BGP sessions that are required to
match expanding traffic demands.
Source Packet Routing in Networking (SPRING)—SPRING on PTX10008 provides additional flexibility
per packet source. It has features such as network path and node protection to support MPLS fast
reroute (FRR) mechanisms, enhanced network programmability, Operation, Administration, and
Maintenance (OAM) functionality, simplified network signaling, load balancing, and traffic engineering
functions.
