  1. T Series Overview

  2. 1st deployed routing node with Matrix Technology Breakthrough economics: 5-7 year router lifespan JUNOS operational simplicity Protects carrier’s brand equity: seamless migration Dependable, rich MPLS Purpose built for large scale converged packet infrastructure HistoryApril 2002: T640 Routing Node

  3. 2 X Entire M40 Capacity on a Single ½ Rack Line Card 1.8M gates T-series: Breakthrough Silicon 770M route lookup/sec Outcome of 3 Year R&D Program Sets New Industry Density & Capacity Benchmarks 160M route lookup/sec 40M route lookup/sec Half Rack Line Card Capacity 2.2M gates 10M gates 1998 2000 2002

  4. Routing Engine Routing Engine SwitchingFabric FPC FPC FPC FPC PIC PIC PIC PIC T- series Architecture • Clean partitioning of functionality • Distributed packet processing • Any-to-any non blocking switch fabric • Maintains packet priority and order across fabric • 3rd generation chipset • 7 New T-Series ASICS

  5. RE GFPC3 GFPC3 SwitchFabric PFE WAN PFE PFE PFE WAN T-Series System Interconnect • PFEs ( T-series FPC) communicate through switch fabric • Each FPC has one embedded CPU complex which talks to the RE via internal Ethernet WAN WAN

  6. FPC SIB PFE PFE SIB SIB SIB SIB Switch Fabric • Non-blocking topology • Any-to-any connectivity • No single point of failure • Switch Fabric consistsof 3 or 5 Switch Interface Boards (SIBs) • All SIBs fully redundant • Graceful degradation for multiple failures

  7. Switch Fabric Dependability • Switch flow control algorithm is based on transmitting requests and grants • Failure to receive grants allows FPCs to detect broken paths without global communication • Individual PFEs can bypass switch planes with broken paths • Chassis manager can activate redundant switch plane RedundantComponent T-series

  8. Routing Engine3 Routing Engine 3 • Increased levels of scale and performance • Increased memory – 2G Memory • 4 million+ routes • Faster routing protocol convergence • Scalability VPNs, BGP Peers, LSPs etc.

  9. FPC PFE PFE Third Generation FPCs • Flexible PIC Concentrator 3 (FPC3) • Provides 10G of bandwidth per PIC slot • Flexible PIC Concentrator 2 (FPC2) • Provides 3G of bandwidth per PIC slot • Flexible PIC Concentrator 1 (FPC1) – T320 only • Provides 800M of bandwidth per PIC slot

  10. CoS and Qos Enablement • Enabled by Queuing and Memory Interface ASICs • Scaleable • 256 streams per FPC-3 • 1024 queues facing WANper FPC-3 • Flexible queue assignment • Queues are arbitrarily assignedto streams • 8 queues per interface supported • T-Series Internet Processor classification capabilities Priority Queuing D W R R WRED

  11. T640 Routing NodeNew Industry Benchmark • Front panel WAN connect • 640 Gbps throughput • 770 Mpps forwarding • 32 x OC-192c/STM-64 ports • 128 x OC-48c/STM-16 ports • 40 Gig slots • Rear panel local connect • Matrix Technology • Optical backplane extension • Any-to-any, non blocking • 1,280 Gbps throughput • Seamless scale • JUNOS scales to Tbps Speeds • T-series Internet Processor ½ rack Front Rear True ‘Two-Way’ High Density Routing… Front and Rear Connectivity
