Overview

Accelerate deployment of the ideal next-generation network (NGN) with the T-series family: T320, T640, T1600 and the TX Matrix for multi-chassis operations.

Juniper Networks T-series core routers, including the T1600–a 1.6 Tbps system with 100 Gbps per slot–delivers performance without compromise rather than forcing a choice between either rich services or performance. The T-Series core routers offer sophisticated processing capabilities on a true multi-service platform. Providers can reduce operational and capital expenses while easily customizing the solution set and user experience. The result is flexible, powerful and profitable network service delivery.

Building core next-generation networks (NGN) with T-series core routers offers a "pay-as-you-grow" path. Exponential bandwidth growth is accommodated along with seamless integration with the optical transport networks that connect your metropolitan areas. This is especially evident with the in-service migration path from a T640 to a T1600–an in-service upgrade can be completed in less than 90 minutes that more than doubles capacity. Alternative solutions require forklift upgrades and modifications to the transport network.

The data plane in T-series core routers is based on programmable ASICs that provide high security and granular traffic control while handling potentially hundreds of thousands of filtering operations at the highest line rates. Furthermore, Juniper forwarding engines implement the industry’s most sophisticated, predictable and granular policies.

On the control plane is the JUNOS operating system, which operates from edge to core across all Juniper routing platforms. In addition to being the industry’s most proven and trusted network operating system, JUNOS is integrated with Juniper’s Session and Resource Control (SRC) portfolio for policy-driven control of network resources.

Features and Benefits

Multi-terabit Capacity and Multi-chassis Scalability

Total Internet traffic continues to grow at over 80 percent per year. T-series scale and density allow service providers to increase capacity without adding additional systems to the network.

With the TX Matrix, incremental expansion can be made to a 2.5 Tbps system; the new T1600 provides 1.6 Tbps capacity in a single chassis. Future proof architecture scales comfortably to well beyond this capacity as provider needs progress.

High-availability Hardware

High-availability and continuous operation are critical in core routing, where loss of a single routing node can remove service for a wide geographical area.

There is no single point of failure in T-series routers. Component level redundancy is available for routing engines (RE), Control Boards (CB), and switch interface boards (SIB), as well as Power Entry Modules (PEM).

High-availability Software

High-availability requirements in core networks include the elimination of planned downtime. Non Stop Routing (NSR) provides the foundation for seamless system upgrade, and JUNOScript commit script capabilities mean continuous operation under maintenance conditions and topological changes.

Superior Packet Processing via Programmable ASIC-based Packet-forwarding Engine (PFE)

Highly granular QoS, advanced filter based forwarding, flow-based monitoring and DDoS prevention are critical in core routing. Juniper’s programmable ASICs deliver a comprehensive hardware-based system for packet processing. To ensure a nonblocking forwarding path, all channels between the ASICs are oversized, dedicated paths.

Firewall filter capabilities are scalable to hundreds of thousands of entries and include multiple matches and conditions. All competing core routing implementations allow for a mere fraction of the total firewall filter terms supported on Juniper routers without performance degradation.

Wide Range of Interfaces

Combining the functions of previously disparate network elements offers greater network simplicity and retains the service-building advantages of the overlay networks being replaced by the converged network.

Interfaces on T-series range from DS3 to OC-768. Juniper provides the largest variety of interfaces among core routing platforms. This interface variety (both optical and copper) is unique in the market.

Solid, Modular, Feature-rich Software

Each JUNOS process runs in protected memory to guard against system crashes and to ensure that applications do not interfere with each other. JUNOS has the greatest breadth of features and is the most stable network operating system in the industry.

Each release of JUNOS runs consistently across all Juniper Networks routing platforms and feature sets. JUNOS was conceived and implemented as a modular design. Advanced features include point to multipoint MPLS, MPLS VPN, IPv6 PE and many more unique features among core routers.

Optical Transport Integration

Integrating optical transport technology into routers provides flexibility in provisioning that leads to the rapid rollout of new services while retaining Layer 3 intelligence to ensure prompt responses to topology changes.

PIC support includes 10 GE Tunable DWDM, OC-768 and 4-Port OC-192. GMPLS is continually enhanced along with Ethernet OAM functionality.

Logical Routing Capability

With logical routers, providers can manage their CapEx by consolidating the network hierarchy onto a single highly available router or by scaling service offerings in midsize to large POPs with multi-chassis routers.

Using logical routers, the applications, configurations, protocols and routing tables assigned to a logical router belong to that one logical router. Juniper’s best-in-class logical routing support is the only implementation with shared uplink support.

Applications

The Juniper Networks multi-service, traffic-engineered core is the premier core routing option in the industry. T-series and JUNOS functionality offer the most resilient, high-performance and flexible applications for backbone carriage of content-intensive consumer and business traffic.

With a multi-layered combination of hardware and software, network operators can simplify network operations and deployment while delivering the industry-leading performance, reliability and availability required to support multiplay services such as IPTV, video on demand and advanced mobile applications.
Service tunnels (enabled through label switched paths or LSPs) are built across core networks to provide traffic engineered paths for specific QoS, availability and advanced service processing requirements. Historically, these service tunnels have been essentially static connections and cannot be easily or quickly changed or adjusted. While this approach has been sufficient for relatively predictable best-effort service, emerging services like video on demand are changing traffic patterns and increasing quality requirements. The ability to dynamically modify paths through the network core (see figure) has a huge positive impact on a provider’s ability to deliver new services efficiently, cost effectively and reliably.

Service-aware, Content-optimized Core

In the case of a video serving network, a user request for a high-bandwidth, high value service would result in the dynamic adjustment of network resources between the subscriber and the video serving location. These policy changes would be initiated by an interaction between the content application and the providers’ service-aware policy manager.

Juniper Networks provides the leading features demanded by service providers today to handle the massive growth in core bandwidth requirements. These features include MPLS DiffServ-TE, sub-50 ms convergence and seamless upgrades, Point to Multipoint LSP, Hierarchical MPLS and service delivery coupled with Juniper’s Session and Resource Control portfolio.

This degree of policy control needed in today’s core is beyond the scope of an individual network element’s OS. To address the requirement, intelligence is needed on the policy and control layer, sitting above the infrastructure and connecting to both service delivery platforms and to networking infrastructure.

This is where the Session and Resource Control portfolio comes in. With innovative policy and control software such as the SDX-300 Service-delivery System, the SRC Modules and the C-series Controller platforms LSPs can be managed on a per-stream basis providing admission control based on traffic load, time-of-day network changes or dynamic policy/filter management. MPLS TE could then be used to choose another available LSP.
