The Juniper Networks PTX1000 Packet Transport Router is a fixed-configuration router that supports
10-Gbps, 40-Gbps, and 100-Gbps port speeds in a compact 2U form factor, enabling service providers to
organically distribute peering points throughout the network.
The system architecture cleanly separates control operations from packet forwarding operations. This
design eliminates processing and traffic bottlenecks, permitting the PTX1000 to achieve high performance.
•
Control operations are performed by the Routing Engine, which runs the Juniper Networks Junos
operating system (Junos OS). The Routing Engine handles routing protocols, traffic engineering, policy,
policing, monitoring, and configuration management. Junos OS is installed on the PTX1000 router’s
internal 2 x 64-gigabyte (GB) M.2 SATA solid-state drives (SSDs). The 64-GB SSDs have 50 GB of usable
space—the remaining space is reserved. The Routing Engine is enhanced by a 2.5-GHz quad core Intel
CPU and 32 GB of SDRAM.
