juniper NETWORKS ATASHEET TX SERIES PA RANSPORT SWIT Product Description Service providers today are faced with significant challenges. Bandwidth utilization is increasing exponentially, while revenue per bit is dropping. This is causing margins to diminish and increasing the need for technology that will help providers streamline their operations and reduce their total cost of operations. Network Complexity: The service provider core network funnels all traffic and is critical to avoiding network disruptions. The technology for the core should have a simple architecture, be automated, and function with minimal configuration changes. Providers also need technology that delivers the highest possible redundancy. Օ Static Architecture: Today's services and traffic patterns are unpredictable. Network requirements change frequently with the introduction of new services. Architectures need to be flexible and dynamic in order to adapt to these changes in traffic patterns and services. 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. Օ 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. Product Overview Service providers need a high density platform for their core networks. The platform needs to support a dense, cost optimized, highly available, and simplified network architecture. Juniper Networks PTX Series Packet Transport Switch addresses service provider supercore needs while improving total cost of ownership (TCO), optimizing power use, and significantly reducing space utilization. 1

The architecture of the supercore needs to be highly flexible to accommodate changes in traffic characteristics. This is a critical characteristic for service providers, as they cope with an ever changing environment of new applications, data center consolidation, and cloud services expansion. Modeling has indicated that the supercore needs to be packet-based to be most efficient. Multiplexing and aggregation need to happen at the packet level, and integration of the optical and packet layers is needed to optimize the economics of the supercore. MPLS is the technology of choice for packet transport....
