MPLS FRR further enhances resiliencyfor MPLS/VPLS services by enabling LSPsto be restored within 50 ms in case ofphysical or logical link failureAccess/AggregationMPLS/H-VPLS,Q-in-Q, PBB/TEMetro/CoreMPLS/H-VPLS,Q-in-Q, PBB/TEAccess/AggregationMPLS/H-VPLS,Q-in-Q, PBB/TE> MPLS OAM capabilities include LSP Pingand LSP Traceroute, which can be usedto verify the LSP status and topologyVLANMPLS LSPDual tagpush/pop/stampMPLS LSPDual tagpush/pop/stampEVCEVC (PW) MPLS LSPVLANThe 5305’s MPLS/VPLS capabilities arecomplemented by the MPLS/VPLS featureson the LE-311v Service Delivery Switch,allowing network operators to deploy acost-effective mix of LE-311v and 5305systems within their network infrastructuresto support carrier-grade VPLS, H-VPLS, VPWS,and MPLS interworking services, as shown in Figure 3.Industry-leading Interworking CapabilitiesVLANVLANIn addition to the MPLS/VPLS/H-VPLS/VPWS features notedabove, the 5305 supports the interworking of customer andprovider (Q-in-Q) VLAN services and EVCs with MPLSpseudowires and VPLS VPN services. This enables networkoperators to deploy VPWS, H-VPLS, and/or VPLS VPN servicesto targeted customers while providing Ethernet VLAN and VPNservices on the same 5305 platform. The 5305 also supportsthe interworking of MPLS LSPs, pseudowires, and VPLS VPNswith PBB-TE service instances and tunnels, including supportfor PBB-TE spokes to interwork with VPLS mesh LSPs.Q-in-Q / PBB-TE TunnelQ-in-Q / PBB-TE TunnelMPLS LSPto a fast-growing customer base. The 5305 PBB-TEimplementation has the following elements:> IEEE 802.1ah PBB MAC-MAC frame format, includingbackbone VLAN IDs for tunnel routing, and a serviceinstance field that can support up to 16 million individualservices within a single PBB-TE network> PBB-TE tunneling protocol with built-in backup tunnels anda dual homing tunnel optionEVCQ-in-Q / PBB-TE Tunnel EVCFigure 4. 5305 VLAN/Q-in-Q/PBB-TE/MPLS interworkingEVC Q-in-Q (PW)/ PBB-TE TunnelEVC Q-in-Q (PW)/ PBB-TE Tunnel> PBB-TE tunnel monitoring and 50 ms failover via IEEE802.1ag Continuity Check Messages (CCMs)VLANVLAN> Advanced management mechanisms that support theprovisioning of PBB-TE service instances and enableprovider networks to deliver point-to-point services with highlevels of scalability, reliability, manageability, and securityThe breadth and sophistication of the 5305’s MPLS/VPLSfeatures and its support for the interworking of MPLS/VPLS,PBB-TE, and VLAN/Q-in-Q services firmly establishes the5305 as the industry-leading Carrier Ethernet service deliveryand aggregation platform. No other product currentlysupports MPLS/VPLS, VLAN, EPL/EVPL/ELAN/E-Tree, andPBB-TE services on one system, and no other productsupports interworking between all these connection typesover its Ethernet interfaces, as shown in Figure 4.PBB-TE: Connection-Oriented Carrier Ethernet TransportAs mentioned above, the IEEE 802.1Qay PBB-TE specificationincludes support for built-in backup tunnels to ensure theavailability of a predictable tunnel route over the backbone,with normal and failover paths. The 5305’s PBB-TEimplementation uses 802.1ag CFM mechanisms to detectfaults and achieve 50 ms service restoration times comparableto those available with SONET/SDH.Figure 5 illustrates a typical PBB-TE application with tunnel andpath redundancy; the tunnels are explicitly routed, which ensuresPBB-TE is an innovative technology that extends and adaptsEthernet to provide carrier-grade transport over Metro andWide Area Networks (MANs and WANs). PBB-TE has beenstandardized as IEEE 802.1Qay, and the 5305 is fully compliantwith this new industry standard.The 5305’s advanced PBB-TE feature set delivers a reliable,resilient, and cost-effective connection-oriented Ethernettransport solution, ideal for delivering a variety of new servicesPrimary TunnelBackup TunnelPrimary TunnelContinuity Check MessagesPBB-TEBackup TunnelContinuity Check MessagesFigure 5.

superior management visibility and enhanced fault isolation. Abroad array of Ciena Carrier Ethernet switches can be utilized tobuild PBB-TE networks, including the 5305, the 3960, the 3940,the 5140, and the LE-311v.Based on extensions to current Ethernet standards, PBB-TEenabledproducts maintain compatibility with existing Ethernetdeployments, which means that the 5305 can deliver resilientPBB-TE connection-oriented Ethernet services with guaranteedQoS to thousands of customers while interoperatingseamlessly with an installed base of multi-vendor switching androuting systems that do not support PBB-TE. Because theadvantages of PBB-TE are available without changes toexisting network equipment or architectures, the 5305 canprovide PBB-TE resiliency and traffic engineering benefits whileensuring superior investment protection.Flexible VLAN and MEF ServicesIn addition to the comprehensive MPLS/VPLS and PBB-TEcapabilities noted above, the 5305 has a robust Ethernet L2VPNfeature set that includes 802.1Q VLANs, 802.1ad ProviderBridging (Q-in-Q VLANs), and advanced VLAN tag manipulationand mapping capabilities. These VLAN features enableprovisioning of MEF-standard Ethernet Private Line, EthernetVirtual Private Line, Ethernet-LAN (E-LAN), Ethernet VirtualPrivate LAN (EVP-LAN), and Ethernet-Tree (E-Tree) services.The 5305’s highly flexible VLAN tag manipulation and mappingincludes VLAN ID translation, dual-tag insertion, removal, andmarking (sometimes called “push-pop-stamp”), CoS markingand re-marking, L2 to L3 and L3 to L2 CoS mapping andre-marking, and the ability to perform push, pop, and stampoperations for two or more levels of VLAN tags.Sophisticated Virtual Switch ArchitectureThe 5305 has a sophisticated virtual switching architecture thatenables every port to be an independent VLAN, MAC, and IPaddress domain, and allows overlapping VLAN and IP addressesto be configured on different 5305 ports. In addition, each virtualswitch is an independent switching and bridging domain.This enables customers to maintain private VLAN and IPaddressing schemes and insures security and separation ofcustomer traffic for L2VPNs (E-LAN, E-Tree) and EVCs (EPL,EVPL). This arrangement enables the 5305 to support VLANsfrom many customers on each physical port, up to 4,094 VLANson each Virtual Switch, and up to 30,000 VLANs per 5305system, for unparalleled service scalability and flexibility. The5305 architecture and system resources can also support up to500,000 unique MAC addresses per line module and up to twomillion MAC addresses per system.PBB-TE MACin-MACDomainMAC AddressDomainVLAN(.1Q, Q-in-Q)Tag DomainThe following points summarize the key characteristics andcapabilities of the 5305’s virtual architecture and advancedVLAN feature set:> Every virtual switch is an independent broadcast/floodingdomain> Every port is an independent VLAN, MAC, and IP addressdomainMPLS/VPLS/H-VPLSDomain> Support for more than 4,094 simultaneous VLANs per port,and 30,000 VLANs, 10,000 virtual switches, and 30,000 QoSflows per system> Each port and virtual switch can accommodate a mix ofuntagged, VLAN, and Q-in-Q VLANs, as well as MPLS andPBB-TE services> Customer-, service-, and network-level priority treatmentusing flexible priority marking> Flexible tag manipulation, including untagged, single, anddouble-tagged combinations, natively or tunneled> Low- or zero-touch provisioning using pre-provisionedVLAN(s) and Q-in-Q attachments> Logical flows and traffic treatment using flexible flowclassification> Flexible E-Type manipulation to suit various applicationenvironmentsMetro 1 Metro 2Figure 6. 5305 Virtual Switching> Subscriber identity and server parameter conservation,to suit carrier network requirements> Full MEF-compliant services for all different tagging schemesCarrier-Class Ethernet OAMThe 5305 supports a rich set of OAM features defined in thelatest versions of IEEE, ITU, and IETF standards, including:> IEEE 802.3ah EFM physical layer OAM, including link eventsand remote loopbackVS 1 VS 2PBB-TE MACin-MACDomainMAC AddressDomainAddresses and Tags can be reused in each Virtual SwitchVLAN(.1Q, Q-in-Q)Tag DomainMPLS/VPLS/H-VPLSDomain5
