  15. Service Providers technology The need for ethernet

  16. Legacy technology for Service Providers Core Network Access POP Access POP • Core network (legacy) technology: • ATM • SDH • POS • Access POP (legacy) technology: • DSL • ISDN • X.25 • Frame relay • Serial links What about Ethernet?

  17. The Carrier-grade Ethernet revolution • Ethernet evolved significantly during the past decades • Ethernet now offers standardized 1Gbps connections over 150km distances • Ethernet now offers standardized 10Gbps connections over 80 km distances • Ethernet will soon (2010) offer 100Gbps connections over a single fiber pair, establishing a new benchmark in terms of link speed. • WDM optical backbones may extend the Ethernet reach • High-speed Ethernet Metropolitan Area Networks are a de-facto standard for new installations

  18. M-Series and C-Series adoption of Carrier-grade Ethernet • E-LINE (including Ethernet Private Line and Ethernet Virtual Private Line) • E-LAN • E-TREE • Flexible Carrier Ethernet Service Delivery using Layer 2 VLANs, Provider Bridges (802.1ad) or Provider Backbone Bridges (802.1ah) STANDARDIZED SERVICES • PBB functionality with 10-GE upgradability • Best in class MAC scalability • Unparalleled scalability in Carrier Ethernet services when combined with VPLS on the M-routers • Innovative ESI framework • High-touch QoS management with advanced QoS controls • Ingress and Egress bandwidth profiles with 2-rate, 3-color policers • Egress traffic shaping • Advanced remarking capabilities CARRIER-GRADE ETHERNET QUALITY OF SERVICE SCALABILITY SERVICE MANAGEMENT RELIABILITY • 802.1ag Connectivity Fault Management • CCM, LinkTrace, and Loopback messages • MAC ping and MAC traceroute • Management of end-to-end services using MEF 17 Service OAM Framework • Single link LACP for ensuring bi-directionality • Standard L2 protocols and Metro Ring Protocol (MRP or MRP-II) with PBB and PB networks • Rapid recovery from node/link failures in overlapping rings • Layer 2 Tunneling of Customer Protocols • Integration of Layer 2 resiliency protocols with VPLS

  19. Service Providers technology The need for Virtualization

  20. Virtualizing the SP Network • Provider Bridges (PB) • Provider Backbone Bridges (PBB) • MPLS L3 VPN • MPLS L2 VPN Service Provider Network Customer A Customer A - VPN Customer A Customer A Customer B Customer B Customer B - VPN Customer B

  21. Provider Bridge (PB) frame format S-TAG Inserted by Provider Edge Bridge C-TAG inserted by customer • Also called Q-in-Q • The switching in the SP network is done via the S-TAG • A single S-TAG may “hide” all 4k VLANs (C-TAG) from customer site • Up to 4k different customers may be multiplexed in the same network • Original customer MACs are still learned from all SP nodes Original Frame

  22. Provider Bridge (PB) operations Customer A (1000 MACs) Customer A C-VLAN 5,6,7 C-VLAN 5,6,7 S-VLAN 101 (contains C-VLAN 5,6,7) S-VLAN 102 (contains C-VLAN 5) Customer A (2000 MACs) Customer B S-VLAN 103 (contains C-VLAN 6,7,8) C-VLAN 5 C-VLAN 5 C-VLAN 6,7,8 C-VLAN 6,7,8 Customer C (3000 MACs) Customer C Intermediate node learns 1000+2000+3000=6000 MACs Provider Bridges: a powerful approach for L2 virtualization

  23. Provider Backbone Bridge (PBB) • Standardized as part of IEEE 802.1ah, also called MAC-in-MAC • Enhances PB paradigm • Encapsulates the Customer frame within a new SP frame (effectively hiding MACs and VLANs from customer networks) SP Frame Customer Frame

  24. Provider Backbone Bridge (PBB) operations Customer A (1000 MACs) Customer A C-VLAN 5,6,7 C-VLAN 5,6,7 S-VLAN 101 (encapsulates Customer A frames) S-VLAN 102 (encapsulates Customer B frames) Customer A (2000 MACs) S-VLAN 103 (encapsulates Customer C frames) Customer B C-VLAN 5 C-VLAN 5 Node 1 Node 2 Node 3 C-VLAN 6,7,8 C-VLAN 6,7,8 Customer C (3000 MACs) Customer C Intermediate node learns Node1+Node2+Node3 MAC = 3 MACs Provider Backbone Bridges: a better approach to scale L2 virtualization

  25. Service layer: L3VPNs (M-Series) L2VPNs (M-Series, C-Series) LDP, RSVP-TE MPLS layer OSPF, ISIS, BGP-4, MP-BGP Routing layer Ethernet (1GE, 10GE, 100GE) Physical layer MPLS in Service Providers networks - Protocol model Customer Domain VPN layer Provider Domain

  26. Further benefits of MPLS • Fast restoration of service in case of failure (50ms) • From a “Best effort” IP approach to a “Guaranteed Service” approach • Reserved bandwith • Path control • Traffic segregation and Customer Virtualization

  27. MPLS L3VPNs Traffic is segregated Into VRFs Internal MP-BGP mechanisms transfer the customer route only to the customer other endpoints A routing protocol runs between the CE and the PE Service Provider Network Customer A - VPN VRF Customer A Customer A CE PE As a result, a Customer VPN is formed and traffic may flow in a segragated way via MPLS

  28. M-Series routers M-Series routers M-Series routers MPLS L3VPNs – users’ view of the service BGP/MPLS VPN CE Regular router CE Regular router MPS Backbone CE Regular router Customer’s CE devices think that they are connected to their own private routed network

  29. M-Series routers and L3VPNs • M-Series support all routing protocols for CE-PE connection • M-Series provide up to 400 simultaneous VRFs • Full implementation of BGP-4 and MP-BGP • Full implementation od label distribution protocols: • LDP (Label Distribution Protocol) • RSVP-TE (Resource Reservation Protocol – Traffic Engineering)

  30. L2VPN approach • A simpler, yet powerful approach to MPLS VPNs • The SP Transport Networks only provides a transparent L2 service between remote sites • Remote data centers with clustering services requiring “direct” same-subnet visibility • Transparent transport service between customer routers, exchanging private customer routing information • 2 flavors of L2VPNs • point-to-point (VLL – Virtual Leased Lines) • point-to-multipoint (VPLS – Virtual Private LAN Services)

  31. M-Series C-Series M-Series C-Series M-Series C-Series M-Series C-Series M-Series C-Series MPLS L2VPNs: users’ view of the Service Virtual Leased Line (VLL) MPLS Backbone Regular Switch/Router Regular Switch/Router Customer’s CE devices think that they are connected via a leased line Virtual Private LAN Service (VPLS) MPLS Backbone Regular Switch/Router Regular Switch/Router Regular Switch/Router Customer’s CE devices think that they are connected to a switch

  34. FLS FLS FLS Service provider networks via Mixed PB/PBB + VPLS approach PB/PBB VPLS PB / PBB Enterprise access MPLSCore PBN PBN PBBN PBBN PBN PBN PON Aggregation Residential triple-play Mobile Backhaul DSLAM Aggregation Applications using a mixed PB/PBB + VPLS approach : • Medium- to large–sized networks • MPLS benefits required at least at the Core • Access technology “intrinsecally” L2 (DSLAM, PON ONTs, FTTx, Mobile backhaul) • New, efficient, secure architecture while preserving investment in existing MPLS core, and isolating the MPLS PE device from learning customer MAC addresses

  35. Service provider networks via a Full end-to-end MPLS approach MPLS end-to-end 1GE access Network B04M Central NOC 10GE service delivery B08M Highly scalable 10GE / n*10GE backbone B16M 10GE access network B04M/B08M Applications using an end-to-end MPLS approach : • Greatest degree of virtualization • Choice for highest-demanding SPs • Fast restoration of services in case of failure • Concurrent use of L3VPNs and L2VPNs • Ubiquitous, on-demand service delivery to Customers
