  1. 1. Extreme Networks PBT Strategy Martin van Schooten Sr. Director, Worldwide Field Marketing March 2007
  2. 2. PBT and it’s Target Market <ul><li>Many Service Providers have split decision making and budgeting </li></ul><ul><ul><li>Data Group – IP Router & MPLS Focused </li></ul></ul><ul><ul><li>Transport Group – SONET/SDH & Cross Connect focused </li></ul></ul><ul><li>PBT addresses the requirements and operational work flow of the transport group </li></ul><ul><ul><li>Deterministic network behavior </li></ul></ul><ul><ul><li>End-to-end resiliency </li></ul></ul>
  3. 3. Service Delivery Evolution Network Economics High Low High Low Service Capabilities Circuit Switching Layer 3 MPLS Layer 2 MPLS PBT Multi-Dimensional Ethernet Traditional Ethernet T-MPLS
  4. 4. PBT key benefits <ul><li>Deterministic network behaviour </li></ul><ul><ul><li>Nailed-up circuits, no Ethernet learning and flooding </li></ul></ul><ul><li>Resilient network designs </li></ul><ul><ul><li>End to end circuit based resiliency </li></ul></ul><ul><ul><li>50ms failover times </li></ul></ul><ul><li>Familiar network operations compared to an MPLS approach </li></ul><ul><ul><li>No need for new personnel with Layer 3 experience </li></ul></ul><ul><ul><li>No need to tackle the complexity of MPLS or MPLS Traffic Engineering </li></ul></ul><ul><ul><li>Maintaining current operational model expected to yield OPEX savings </li></ul></ul><ul><li>Significantly lower CAPEX compared to Ethernet over SONET/SDH or MPLS models </li></ul>
  5. 5. Ethernet Technology Enhancements Provider Backbone Transport MAC-in-MAC (802.1ah) Provides massive scalability Ethernet NNI (MEF E-NNI) Extends service reach across provider boundaries Ethernet OAM (802.1ag) End-to-end resiliency with continuity checks Deterministic, Resilient and Familiar
  6. 6. <ul><li>Provides scalability required for service provider deployments </li></ul><ul><ul><li>Eliminates address space scalability issue </li></ul></ul><ul><ul><li>Solves economic issues with MAC table size expansion </li></ul></ul><ul><li>Provides backwards compatibility for easy implementations </li></ul><ul><ul><li>Works in conjunction with 802.1ad (Q in Q) </li></ul></ul><ul><li>Reduces carrier concerns about building large layer 2 networks </li></ul>Provider Backbone Bridging Customer Edge (VLAN) Customer Edge (VLAN) Q in Q Encapsulation Provider Backbone Bridge (MAC in MAC) Q in Q Encapsulation
  7. 7. Ethernet OAM for End-to-End Resiliency Service Provider 2 Service Provider 1 Customer Customer Service Provider 1 Provider 2 Core Network Provider Domain Operator Domain Operator Domain Operator Domain Continuity Check Messages Continuity Check Messages
  8. 8. Ethernet NNI to Extend Service Reach <ul><li>Allows peering between provider Ethernet services </li></ul><ul><li>Increases carrier reach with Ethernet service extension to off-net sites </li></ul><ul><li>Uses a combination of technologies </li></ul><ul><ul><li>Link Aggregation </li></ul></ul><ul><ul><li>VLAN C-VID/S-VID translation </li></ul></ul><ul><li>MEF Standard expected later this year </li></ul>Provider 1 Provider 2 E-NNI
  9. 9. Next Generation Networking Developments <ul><li>IEEE PAR (project authorization request) for PBT goes to the executive committee for the March plenary meeting </li></ul><ul><li>Extreme & Nortel PBT Interoperability Demonstration </li></ul><ul><li>IEEE 802.1ah and 802.1ag reach sponsor ballot stage </li></ul><ul><li>PBT Open Interoperability showcase </li></ul><ul><li>MEF E-NNI Letter Ballot </li></ul><ul><li>Extreme FCS release for PBT on BD10K and BD12K platforms </li></ul><ul><li>IEEE PBT could reach sponsor ballot in the IEEE in 18 months </li></ul>3 2007 2008 | 5 7 1 2 4 6 Standards Vendors
  10. 10. Migration to PBT <ul><li>PBB (MAC-in-MAC) networks can be deployed today </li></ul><ul><li>PBT traffic engineered trunks can be added later </li></ul><ul><ul><li>Both can run on the same switches at the same time </li></ul></ul><ul><li>PBT Ready hardware </li></ul>Customer Site 1 Customer Site 2 Provider Backbone Bridge (MAC in MAC) IP Service Edge or MPLS Core
  11. 11. PBT versus T-MPLS <ul><li>Similarities </li></ul><ul><li>Both recognize the importance of meshing with service provider transport group requirements </li></ul><ul><ul><li>Connection oriented technology </li></ul></ul><ul><ul><li>Nailed-up circuit support </li></ul></ul><ul><li>Both Require a new control plane </li></ul><ul><li>Differences </li></ul><ul><li>PBT can support multi-point to multi-point services with PBB </li></ul><ul><li>PBT Ethernet OAM better defined than MPLS OAM </li></ul><ul><li>PBT leverages the economics of Ethernet </li></ul><ul><li>PBT has support from a growing group of influential service providers </li></ul>
  12. 12. Extreme Networks - PBT Product Plans <ul><li>PBT will be offered on the BD12K and BD10K platforms </li></ul><ul><li>Software only upgrade – hardware support is there </li></ul><ul><li>New smaller BD12K chassis will launch in April extends PBT closer to the edge and to smaller central offices </li></ul><ul><li>Interoperability Demonstration this summer with Nortel </li></ul><ul><li>Open interoperability testing later in the year </li></ul>
  13. 13. Key benefits for carrier transport groups <ul><li>Deterministic network behaviour </li></ul><ul><li>Resilient network designs </li></ul><ul><li>Familiar network operations compared to an MPLS approach </li></ul><ul><li>Significantly lower CAPEX compared to Ethernet over SONET/SDH or MPLS models </li></ul>
