The Juniper Networks PTX5000 Packet Transport Router is designed for large networks and network
applicaons, such as those supported by ISPs and high-volume content providers.
Benets of the PTX5000 Router
• Increased scalability—The PTX5000 scales to 24 Tbps in a single chassis, supporng up to 1536 10-
Gigabit Ethernet interfaces, 384 40-Gigabit Ethernet interfaces, and 240 100-Gigabit Ethernet
interfaces, giving service providers the performance and scalability needed as networks grow. The
purpose-built ASICs in the PTX5000 provide enhanced packet processing for both full IP
funconality and MPLS transport, accommodang scale as trac connues to increase and
opmizing IP/MPLS transit funconality.
