Alcatel-Lucent 7705 SARSERV ICE AGGREG AT IO N ROU T ER REL E A SE 4 .0The Alcatel-Lucent 7705 Service Aggregation Router (SAR) portfolio delivers industry-leading IP/MPLS andpseudowire capabilities in compact platforms with the ability to reliably groom and aggregate multiple media,service and transport protocols onto an economical packet transport infrastructure.Alcatel-Lucent 7705 SAR-FAlcatel-Lucent 7705 SAR-8Alcatel-Lucent 7705 SAR-18The Alcatel-Lucent 7705 SAR portfoliois optimized for multiservice adaptation,aggregation and routing, especiallyonto a modern Ethernet and IP/MPLSinfrastructure. Leveraging the powerfulService Router Operating System (SR OS)and 5620 Service Aware Manager(SAM), it is available in compact, lowpower consumption platforms deliveringhighly available services over resilientand flexible network topologies.The 7705 SAR is well suited to theaggregation and backhaul of 2G, 3G andLTE mobile traffic — providing costeffective scaling and the transformationto IP/MPLS networking. Business servicesmodernization is supported in thetransition from legacy to consolidated,packet-based operation. Hugely reducedequipment footprints are achievablewith reduced energy costs. Industries,enterprises and government organi zations can deploy with confidence,achieving reliable and resilient supportof legacy and advanced services.The Alcatel-Lucent 7705 SAR owes muchof its development heritage to theAlcatel-Lucent Service Router (SR)product line. Sharing much of themarket-leading feature set of thatproduct line, the Alcatel-Lucent 7705 SARbrings a powerful, service-orientedcapability to the RAN, specifically inform factors and at-price points thatare particularly appropriate for cellsites and hub locations in addition todenser points of concentration. Withend-to-end service management underthe Alcatel-Lucent 5620 managementportfolio, the Alcatel-Lucent 7705 SARgreatly augments the IP/MPLS RANtransport solution from Alcatel-Lucent.Service aggregation andnetworkingTo provide the most efficient transportsolution, the Alcatel-Lucent 7705 SARcan employ pseudowire encapsulationmethods to map services end to end.The use of pseudowires ensures that thekey attributes of the service are main tained, while using a cost-effectivepacket environment to aggregateservices. In addition to pseudowiretransport, IP routing and forwardingand Virtual Private LAN Service (VPLS)are supported. Services such asAsyn chronous Transfer Mode (ATM),inverse multi plexing over ATM (IMA),Ethernet and TDM traffic can be nativelyswitched across the 7705 SAR.
The Alcatel-Lucent 7705 SAR supportsRFC 5086 — Structure-Aware TDMCircuit Emulation Service over PacketSwitched Network (CESoPSN) and alsoRFC 4553 — Structure-Agnostic TDMover Packet (SAToP) for the encapsulationand transport of TDM traffic; forexample, from mobile 2G, TDM-attachedbase stations. The use of circuitemulation service (CES) ensures thatonly the active time slots are transported, keeping bandwidth usage toa minimum. Also, the Alcatel-Lucent7705 SAR supports RFC 4717 — Encapsulation Methods for Transport of ATMover MPLS networks; N:1 cell mode issupported. Multiple access ATM portsare bundled together to attain higherspeeds using IMA. The IMA protocol isterminated on the Alcatel-Lucent 7705 SAR,and only the cells containing user datathat belong to a virtual circuit/virtualpath (VC/VP) structure are transported. RFC 4448 — EncapsulationMethods for Transport of Ethernetover MPLS Networks is also supported.To offer greater scalability, all thetraffic out of an Ethernet port canbe carried over a single Ethernetpseudowire or, alternatively, a pseudo wire can be created for each VLANthat is assigned to a different serviceor end customer. IP pseudowires aresupported and provide the abilityto deterministically carry IP trafficbetween disparate media. For example,IP traffic can be carried between aPoint-to-Point Protocol (PPP) (orMulti-Link Point-to-Point Protocol(MLPPP)) access and an Ethernetconnection. The 7705 SAR product linesupports Border Gateway Protocol(BGP)/MPLS Virtual Private Networks(VPNs) to allow the separation of Layer 3traffic between different groups ofusers or organizations. Virtual PrivateLAN Service (VPLS) is supported for thedelivery of Layer 2 VPNs. Analog voiceencoding and transport is available onthe 7705 SAR-8 and the 7705 SAR-18.Voiceband analog traffic can be carriedover a modern network infrastructurebetween two analog devices using eithertraditional T1/E1 network interfaces orover Ethernet or MLPPP interfaces.2Alcatel-Lucent 7705 SAR Release 4.0 Data SheetHighly flexible network infrastructureoptions include the use of MPLS, IP orGRE (Generic Routing Encapsulation)tunneling for aggregated traffic. Whendynamic MPLS signaling is deployed,the end-to-end pseudowire is established using targeted label distributionprotocol (T-LDP) and the MPLS tunnelusing LDP. In addition to efficientLDP-based dynamic signaling, staticprovisioning of both the MPLS tunneland the pseudowire is supported.GRE or IP tunneling allows low-cost,ubiquitous IP networks to be usedfor backhauling; for example, for thetransport of HSPA (High Speed PacketAccess) off-loaded traffic using DSLaccess media.marking are carried out based on thefollowing categories:Classification (Layer 1/Layer 2/Layer 2.5and/or Layer 3 header): Time slot/port Ethernet port/VLAN ATM service category (CBR/rt-VBR/nrt-VBR/UBR) ATM VC Ethernet 802.1p/VLAN IP DSCP/MPLS EXPMarking: Layer 2 (802.1p) Layer 2.5 (EXP) both for tunneland PWE3 Layer 3 (DiffServ)Label switched routingThe 7705 SAR can be configured aseither a Label Edge Router (LER) ora full Label Switched Router (LSR).Label Switched Paths (LSPs) can besignaled using either the LabelDistribution Protocol (LDP) or theResource Reservation Protocol withTraffic Engineering (RSVP-TE). The7705 SAR brings a strong suite oftraffic engineering and resiliencycapabilities using functions such asConstraint-based Shortest Path First(CSPF) routing, Fast Reroute (FRR),primary and secondary LSPs andredundant pseudowires.The Alcatel-Lucent 7705 SAR utilizesextensive traffic management policies toensure fairness with detailed classificationand hierarchical scheduling including:minimum/maximum, queue type-basedweighted round robin or strict priorityand profiled scheduling, as well asmulti-tier policing to differentiate andprioritize individual services and flows.Quality of service andtraffic management LSP pingIt is critical to maintain the end-to-endquality of service (QoS) for packettraffic. Not all types of traffic have thesame set of requirements. Voice trafficin particular requires low latency andjitter (latency variation) as well as lowloss, whereas data traffic often has lessstringent delay requirements but maybe very sensitive to loss, as packet losscan seriously constrain applicationthroughput. To offer the requiredtreatment throughout the network,traffic flows with different requirements are identified at the access andmarked in-line with the appropriateQoS metrics. Traffic classification and Service distribution path (SDP) pingOperations, administrationand maintenanceIn order to ensure continuity of services,the Alcatel-Lucent 7705 SAR has a fullset of operations, administration andmaintenance (OAM) features including: LSP traceroute Verifies, for example, tunnel connectivity and round-trip delay Virtual circuit connectivity verification(VCCV) Verifies, for example, service levelexistence and round-trip time Extends OAM to pseudowireservices Ethernet OAM functions, for example: 802.3ah: Ethernet in the First Mile 802.1ag: Connectivity FaultManagement Y.1731: Ethernet OAM mechanismsfor fault management — mainlyat a service level

Compact, rugged form factors allow remote sitesto be addressed.Breadth of synchronization solutions with flexible operation, redundancyand independent validation of accuracyAccurate synchronization allows cost-effective deployment over packetinfrastructure and improves the user experience (for example, less data lossand minimal dropped calls in mobile applications). Service Assurance Agent (SAA) Runs in background, periodicallycollecting network ‘health’information from OAM mechanisms(such as VCCV) and monitoring forproblems (such as SLA transgressions)These features, when under thecontrol of the Alcatel-Lucent 5620management portfolio, ensure rapidfault detection as well as efficienttroubleshooting. In particular, SLAscan be proactively monitored by theSAA. This powerful capability allowsthe specification of test suites, policiesand schedules. The tests are thenauto-created, and the results obtainedare automatically compared to predefined SLA metrics. Any transgressionsdetected are automatically reportedthrough the SAA to operations staff.An auto-discovery protocol is supported to allow rapid commissioningof remote devices.SynchronizationCell sites rely on the backhaul networkto provide synchronous interfaces forthe proper delivery of data. In addition,cell sites may rely on the networkinterfaces as stable references withwhich to derive radio frequencies andto ensure reliable subscriber handoverbetween cell towers. Accurate synchronization is also important in wirelinenetworks in maintaining networkoperational integrity; for example,avoiding data underflows and overflows and transmission ‘slips.’The Alcatel-Lucent 7705 SAR supportsexternal reference timing, line timing,adaptive clock recovery (ACR) timing,synchronous Ethernet and also timingdistribution using 1588v2. The 1588v2Master Clock and Boundary Clockfunctions are also supported. Accuracyand high performance of timing overpacket solutions, such as ACR andIEEE 1588v2, are accomplished by acombination of built-in architecturalfeatures, efficiently tuned algorithmsand powerful QoS mechanisms tominimize the delay experienced bysynchronization traffic. These capabilitiesare cornerstones of the design of theAlcatel-Lucent 7705 SAR.
