  1. Passport 8600 Routing Switch Release 3.3

  2. Tactical Strategic CIO’s Priorities • Do more with less • Drive employee productivity with IT • Use IT to grow revenues • Use IT to anticipate customer requirements

  3. Consistent customer experience everywhere Business connectivity via the internet Internet Security for all applications and services Storage and networking at light speed IP telephony succeeds traditional telephony Needs of the future enterprise network

  4. Key Requirements • High Availability • 99999s Reliability means uptime all the time. Bandwidth, Security and Quality of Service ensuring application delivery with fail-over schemes that preserve application integrity. • Operational Simplicity • Simple to install, Simple to maintain, Simple to manage. Reduced complexity through a ‘leaner’ more integrated intelligent infrastructure design. • Low Cost of Ownership • Reduced purchase, installation and maintenance costs through reduced complexity, the ability to consolidate resources and a lower box count.

  5. Applications Drive Infrastructure • Streaming Video • Constant stream of data – no pauses or interruptions • Unidirectional – server to client • Low bandwidth – 2-4Mbps • VOIP (IP Telephony) • Constant stream of data – no pauses or interruptions • Bi-directional – client to client or peer-to-peer • Very low bandwidth – 8kbps-64kbps • Email • Sporadic bursts of traffic – varying size (attachments) • Bi-directional – client to server to client • Varying bandwidth - greedy, will take all available

  6. Two Tier Infrastructure design Edge High density 10/100 Ethernet ports for user connections and Gigabit Ethernet for riser connections. Access security controls and QoS mapping. Core High Density Gigabit Ethernet for riser connections. ATM, SONET and Optical connections for MAN/WAN access and L4-7 Applications switching for Data Center integration.

CPU/Switching Fabric Modules CPU/Switching Fabric Modules CPU Forwarding Table Processing CPU Forwarding Table Processing FABRIC I/O Module Cross Connect FABRIC I/O Module Cross Connect I/O Module I/O Module ASIC Lookup & Packet Processing ASIC Lookup & Packet Processing MEMORY Forwarding & Filtering Tables MEMORY Forwarding & Filtering Tables Passport Architecture All Packets take same path through shared memory switching fabrics to the egress port ensuring consistent low latency and jitter and unmatched multicast scaling All Packet Processing occurs on the I/O Modules with lookup from in memory ensuring scalability and wire rate performance Custom ASICs (RAPTARU) per port perform Packet filtering, forwarding, routing, security & QoS functions

  13. Passport L2 Switching Outer Switches dual-homed using standard link aggregation protocols. • HA Mode • CPU mirroring ensures zero impact failure • Distributed MLT • Link aggregation over multiple modules removes single point of failure. • Split-MLT • Link aggregation used for network resiliency • Two switches act as one • All links active and passing traffic • No need for the additional complexity of multiple VLANs Two Passport 8600s share forwarding tables and act as one through the IST. “Split-MLT is the only mechanism that will protect sensitive applications like VOIP from network outages.”

  14. A Single Gateway address is now balanced across both Passport 8600s. Passport L3 Routing • Routing Protocol Support • RIP1,2, OSPF and BGP4 • VRRP Backup-Master • Simplifies network configuration • Better network utilization • VRRP fast interval timers • Faster VRRP fail-over • Sub-second to match Split-MLT • IP and IPX routing policies • Improved control of routes • Increase security and control. Backup-Master allows an 8600 that is in backup mode to route traffic “Backup-Master simplifies network design by balancing traffic and reducing the number of subnets/DHCP scopes.”

  15. Passport L4-7 Application Switching • Improved Network Utilization • Load balancing of IP applications • Server selection with Health-checking • Metering and controlling bandwidth usage • Improved Performance • Appliance (Cache,SSL) redirection • Streaming media (Language splicing) • Providing fault tolerance • Tighter Security • Network Address Translation • DoS Attack buffer • Processing traffic filters “The Alteon Web Switching module brings Alteon’s market leading L4-7 capabilities to the Passport 8600.”

  16. PIM-SSM acts like a static route for multicast. Passport Multicast Shared memory architecture delivers superior multicast performance • Passport 8600 shared memory architecture is the basis of unequalled Multicast scaling and performance. • PIM-SSM allows source specific multicast trees to be created, essential in mass multimedia (TV) applications. • Fast join and leave capability improves stream setup time and reduces bandwidth. Fast join and leave allows selection of multicast stream just like TV channel hopping

  17. ASIC Based Flow Filters Security Wire Speed QoS Multi-level capabilities Layer 2,3,4 and 7 802.1p (L2) Granular Queuing 8 Hardware queues ensure application delivery Multi-media filters Pre-set VOIP and Multi-media filters simplify QoS deployment. DA IP-SA TCP-Port DATA FCS SA IP-DA XC “Passport Xpress Classification performs wire-speed lookup and packet classification on a per port basis.” Passport QoS “With 8 hardware queues per port the Passport 8600 has QoS granularity for the most demanding environment.”

  18. Passport Configuration 1 2 3 • Pick any starter pack. • 3, 6 or 10 slot chassis • Add redundancy options • Add additional power supplies • Add a second switching fabric • Choose the I/O modules • ‘E’ or ‘M’ Modules • Ethernet 10/100, Gigabit and 10Gigabit • ATM/SONET DS3, OC3 and OC12 • Application Switching

  19. Passport Advantage • High Availability • Industry leading reliability features deliver the only networking solution capable of protecting sensitive applications like VOIP form network outages. • Operational Simplicity • The simplistic approach to network design and deployment with embedded intelligence further enhances reliability and at the same time reduces costs. • Low Cost of Ownership • High Availability and Operational Simplicity combine to deliver the best platform for One Network and increased ROI for the business.

  21. Access Layer PCs, Printers, etc. High Density 10/100 L2 Ethernet switching Aggregation Layer Consolidation point Mixture 10/100 & Gigabit L2/L3 Ethernet switching Core Nucleus, Servers, Metro High Density Gigabit L3 Routing Campus Architecture Floor 1…………..Floor x Design Issues At layer 2 these extra links need to be blocked to prevent network loops. This is usually implemented using a protocol called spanning tree (802.1d) Spanning tree protocol prevents these loops by deciding the best links to use and blocking all the rest. Basically you’re paying for stuff you can’t use ! Building Campus

  22. Spanning Tree Features • Spanning Tree Protocol (STP) • Provides redundant paths and detects loops in L2 networks • Redundant links are activated after failure • Redundant links are not utilized for data traffic • Slow network convergence - minimum of 30 seconds • Fast L3 redundant protocols like VRRP and OSPF depend on slow STP convergence • Spanning Tree Protocol - Proprietary Hacks and Fixes • Uplink Fast, Port Fast, Fast Start • Improves convergence time by 15-30 seconds • Bandwidth is still wasted by blocked ports • 802.1w Rapid Spanning Tree Protocol • Faster convergence, 5 seconds on failure • Same re-convergence, 30 seconds plus on repair • Same restriction on redundant links Spanning Tree will not protect applications

  23. S-MLT Link Aggregation Our Fresh approach to the spanning tree problem “Extends reliability benefits to attached 3rd party switches through 802.3AD link aggregation” • Description • Split MLT makes the two core switches act as one at Layer 2 • Standard Link aggregation protocols used for network resiliency as well as bandwidth • Both Links are active, appear as one, with traffic balanced across all available links. • Advantages • Less complex than spanning tree • Better bandwidth utilization • Faster Fail-over and recovery • Protects applications from outages • In service hitless upgrades “Maintains state of voice and video sessions through fail-over”
