Troubleshooting JUNOS Platforms
Total ChassisReproductionThrough ut
Juniper Networks T S ri s routers range from the T320, designed for a small network core, to the T1600, capable of offering 3.2 Tbps. The T1600 is a multichassis-capable core router that you can upgrade in-service from existing T640 routers. The scale and density of the T1600 allows service providers to increase capacity without adding
forequipment to the network, saving valuable floor space, rack space, and power consumption.
Range of Interfaces
T Series routers provide edge interfaces as well as the core functions required for consolidated point of presence (POP) solutions. All T Series routers, from the T320 to the T1600 and TX Matrix, support a wide range of interfaces, ranging from DS-3 to OC-768, including Asynchronous Transfer Mode (ATM), SONET, Ethernet, and both fixed and tunable dense wavelength-division multiplexing (DWDM) interfaces.
Components Level Redundancy
No single point of failure exists in the entire product line of T Series routers—including Routing Engines (REs), Control Boards (CBs), Switch Interface Boards (SIBs), and Power Entry Modules (PEMs). The redundancy in these components provides high availability and continuous operation in core routing, where loss of a single routing node can remove service for a wide geographical area.

The M Series portfolio rang s from 7 Gbps platforms to 320 Gbps platforms. You can deploy M Series rout rs in various roles within your network. The M Series portfolio uniquely combines IP/MPLS capabilities with service richness, stability, reliability, and
forsecu ity. The M Se ies routers allow service providers to consolidate multiple networks on a single IP/MPLS infrastructure. You can deploy the M Series platforms as a multise vice edge outer, a small or a medium core router, a route reflector, or a

Ethernet Routing with Switching Design |
|
|
Running the same version of JUNOS Software shared by all Juniper Networks core and edge platforms, MX Series routers not only separate control and forwarding functions, but the Ethernet switching separates Layer 2 and Layer 3 forwarding with the intelligence to bridge when possible and route when needed. The platforms support Dense Port Concentrator (DPC) interface cards, offering enhanced queuing capabilities, QoS, L2 switching, and L3 routing services.

The EX Series Ethernet switches run the same JUNOS Software that Juniper Networks routers run. By utilizing a common operating system, Juniper Networks delivers a consistent implementation and operation of control plane features across all products. To maintain that consistency, JUNOS Software adheres to a highly disciplined development process that uses a single source code, follows a single quarterly release train, and employs a highly available modular architecture that prevents isolated failures from bringing an entire system down.
