User manual JUNIPER NETWORKS T4000 DATASHEET

[. . . ] The T4000 is a true multiservice core system that is designed to deliver a reliable, high-performance, and flexible architecture to carry a wide breadth of services over a common IP/MPLS infrastructure. With four terabits of line rate throughput in a half rack chassis, the T4000 offers double the slot capacity of the nearest competitor. In addition, all existing T640 and T1600 systems can be upgraded in service to T4000 systems, offering ultimate investment protection to the existing T Series installed base. The worldwide growth in Internet traffic continues unabated. [. . . ] The T4000 system offers providers the premier core routing option in the industry--an ultra high capacity core with the ability to support hardware virtualization. Juniper Networks Junos® operating system functionality offers the most resilient, high-performance, and flexible applications for backbone carriage of content-intensive consumer and business traffic. developed for rigorous service provider needs. For example, Junos OS is completely modular so that in the unlikely event one module experiences a problem, it is isolated to that specific section of code and does not bring down an entire system. On the hardware side, all major components--including Routing Engines, Control Boards (CBs), Switch Interface Boards (SIBs), and Power Equipment Modules (PEMs)--are redundant. In-Service Hardware Upgrade One of the key architectural choices in the T Series family of routers is the nondisruptive hardware upgrade. Juniper provides unique capabilities for upgrading existing T640 and T1600 routers to T4000 routers. Following such an upgrade, the T4000 provides more than double the capacity of T1600, while only using about 25% more power. The steps highlighting such an upgrade procedure are shown in Figure 1 below. High Availability The T Series architecture allows all Junos OS features and services to operate across many interface types without compromising performance. From its inception, Junos OS was Four easy steps to perform a service hardware upgrade: 1. Upgrade Switch Interface Boards (SIBs) 3. Upgrade fan T640 or T1600 T4000 Figure 1: In-service hardware upgrade of T640 or T1600 to T4000 in four easy steps 2 Features and Benefits The T Series routers are a proven architecture, with over 6, 000 units deployed in the world's largest networks. Table 2: T Series Features and Benefits FEATURE DESCRIPTION BENEFIT Multi-terabit capacity and multichassis scalability High availability (HA) hardware The T4000 supports 4 Tbps in a single chassis and is multichassis capable. This future-proofed architecture scales comfortably as provider needs progress. There is no single point of failure in T Series routers. Component-level redundancy is available for Routing Engines, CBs, and SIBs, as well as PEMs and the internal control plane. T4000 supports continuous operation under maintenance conditions, and topological changes by means of nonstop active routing (NSR) and unified inservice software upgrade (unified ISSU). The T4000 programmable ASICs family delivers a comprehensive, hardware-based system for rich processing. Interfaces on the T Series range from DS3 to OC768 (SONET) and 100GbE for Ethernet. The T4000 provides the largest variety of interfaces in the densest form factor among core routing platforms. T4000 scale and density features allow service providers to increase capacity without adding additional systems to the network. HA and continuous operation is critical in core routing, where loss of a single routing node can remove service for a wide geographical area.
