Juniper Networks J-series Services Routers

December 2005
Test No. ITS05002

Product Overview

The Juniper Networks J-series Services Routers are highperformance, reliable routing platforms designed to deliver today’s real-time, business-critical networking applications. Typically deployed at remote offices or branch locations, the Jseries Services Routers provide enterprises, government organizations, research and education groups with an advanced platform upon which they can build converged IP or IP/MPLS infrastructures. The J-series router family is comprised of three unique platforms:

J2300 Services Router: Fixed form factor platform with two Fast Ethernet (FE) and two factory installed WAN ports designed for small to midsize remote or branch office locations connected by T-1/E-1 data links (frame relay, IP or Internet) or serial connections.
J4300 Services Router: Modular platform designed to support environments that require multiple T-1/E-1 data link (frame relay, IP or Internet) connections with two built-in FE ports and up to six pluggable interface modules. The J4300 is an ideal solution for midsize office aggregation requirements, linking smaller offices using the J2300 to a regional office location.
J6300 Services Router: Modular platform designed for large regional or corporate environments using T-3 connections to perform medium-density/high-speed office aggregation, connecting a number of small/regional offices to a major office or data center location. The J6300 supports two built-in FE ports and up to six pluggable interface modules as well as an optional redundant power supply.

The J-series Services Routers leverage the market-proven JUNOS modular software, which executes multiple functions in parallel on assigned processing resources. The result is a platform that delivers stability and flexibility to enable advanced routing, security and management policies with predictable performance. The J-series Services Routers support a wide range of LAN and WAN interfaces to ensure deployment flexibility.

Independant Validation Claims

From September through November 2005, Independent Testing Services, powered by Network Computing Labs (ITS), was contracted by Juniper Networks to independently validate specific capabilities of its J-series Services Routers. The following claims of Juniper Networks were subject to open and independent testing verification:

The J-series Services Routers are able to maintain maximum WAN throughput rates with minimal performance degradation when the following advanced services are enabled: firewall filters, stateful firewall, NAT/PT, BGP, OSPF and J-flow. Consistent performance was validated for each of the J-series platforms:
- J2300 Services Router at maximum WAN throughput (full duplex) across 2x T-1 interfaces.
- J4300 Services Router at maximum WAN throughput (full duplex) across 8x T-1 interfaces.
- J6300 Services Router at maximum WAN throughput (full duplex) across a T-3 interface.
The J-series Services Routers are able to maintain consistent performance with advanced services (as stated in Validation Claim #1) enabled while converging 350,000* BGP routes and 15,000, 20,000 and 30,000 OSPF routes on the J2300, J4300 and J6300, respectively.

*NOTE: 350,000 BGP routes represents in excess of twice the quantity of BGP routes in use by current Internet backbone routers.

Results Summary

To validate the proposed claims of the J-series Services Routers, ITS created a topology using Spirent’s TeraRouter, Avalanche and Reflector and containing 19 BGP peers with 350,000 BGP routes, an OSPF area with up to 30,000 routes, 1,000 Avalanche clients and 100 Reflector servers.

Transaction-based HTTP, SMTP and DNS traffic (the composition of which was 91%, 8% and 1%, respectively) was generated between the clients and the servers through the J-series Services Routers at the maximum sustained transaction rates of each router’s WAN interface(s). During this transactionbased load, the J-series Services Routers were exposed to the extreme routing conditions that may occur in a large carrier or enterprise environment during a partial network outage. The Jseries Services Routers were exposed to a series of route flap events in which 80% of the BGP routes and 50% of the OSPF routes were withdrawn and then readvertised.

The results clearly demonstrate that the J-series Services Routers maintained consistent WAN throughput rates when all the advanced services described above are enabled as well as during all route flap events.
