space utilization.
• Power Challenges: For service provider core networks, power is one of the most
important considerations. The total cost of power over a few years exceeds the cost of
implementing the network infrastructure for some service providers. This means that
efficient power utilization needs to be designed into new systems.
• Facility Challenges: Service providers cannot keep on growing their facilities
exponentially. They need technology that can scale to support traffic growth without
having to expand their facilities. Also, with an increase in facility size, the cost of power
distribution and cooling can become prohibitively high.
In order to address these challenges, service providers need a new kind of core product
that is much denser and more scalable, power efficient, automated, and redundant
compared to currently available products. With Juniper Networks® PTX Series Packet
Transport Switch, Juniper is introducing a product that meets these requirements and can
fit into the service provider network supercore, as illustrated in Figure 1.

PTX Series
PTX Series Packet Transport Switches are a portfolio of high-performance platforms
that are designed for the service provider supercore. These switches deliver powerful
capabilities based on innovative silicon and forwarding architecture focused on MPLS and
Ethernet. PTX Series Packet Transport Switches are designed to deliver several critical
core functionalities, including game changing density and scalability, cost optimization,
high availability, and network simplification.
