Ready for Anythingadding software application modulesto the Tellabs SmartCore 9200 series,operators over time can expand theircapabilities. These capabilities includecontent and security engines integratedonto line cards for application awareness,analytics, IPSec security termination andeventually packet core functionality.“An operator may deploy theTellabs SmartCore 9200 series as anaggregation Ethernet router today, butwhat that operator really is deploying isa large toolkit,” said Tim Doiron, Tellabsdirector of product management. “Withit, the operator can infuse the networkwith so much flexibility that it can adaptto just about anything the mobile Internetthrows at it in the years to come.”Intelligence for the FutureThe Tellabs SmartCore 9200 seriesfeatures high-density intelligence in the form of SmartCards,as well as distributed routing. Together, these features providethe network visibility and service-optimization capabilitiesoperators need to stay ahead of the fast-changing mobileInternet.SmartCards are fully swappable among all TellabsSmartCore 9200 series chassis and include multiple interfaceoptions, such as Nx10 Gbps, NxGbE, and Nx100 Gbps.SmartCards eliminate the need for function-specific serverblades, spare blades and cards that have no Ethernet interfacefunctionality. They are available in 3 versions:• SC-1: designed for high-density Ethernet applications.• SC-2: identical to SC-1 density plus on-board contentand security engines for added intelligence capabilities• SC-3: increased content and security engine processingfor applications requiring full-rate or higher densitypacket inspection.“By combining traffic management, compute processingand security encryption all on a single card, the SmartCardgives you logical scalability and resource virtualization,”Doiron said. “So if a card has maxed out some dimension ofits capacity, it can use another card’s available capacity orintelligence, giving you even greater scalability.”5 Dimensions of ScalabilityThe SmartCards, together with the new, fully distributedTellabs GeniOS operating system, enable the TellabsSmartCore 9200 series to deliver scalability across 5dimensions: data throughput, control plane, encryption,packet inspection and traffic management. Each of thesefactors are critical as operators adapt their networks to userand traffic trends, and maximizeuser quality of experience andoperator profitability.In terms of bandwidth scalability,the Tellabs SmartCore ® 9280platform is a 10 Tbps-plus chassisin a 16 Rack Unit form factor,while the Tellabs SmartCore ® 9240platform is a more dense 4-slot,4-Tbps-plus 6 RU chassis.The platform’s first iterationwill deliver 100 Gbps per slotand is designed to scale upwardsof 500 Gbps per slot, or 1 Tbpshalf-duplex as operator demandsdictate. Thus, the TellabsSmartCore 9200 series will providea 5-fold capacity improvement overtime.A new kind of operating systembuilt for next-generation networks,Tellabs GeniOS supports multidimensional scalability. Italso enables node and network virtualization and featuresAPIs for third-party applications.The Tellabs SmartCore 9200 series’ ability to ensureoptimal network performance stems from its distributedrouting, processing and forwarding design. Fully distributedrouting “will become more and more valuable to mobileoperators as they start targeting the embedded devicesspace, which will become increasingly dependent on IPv6,”said Patrick Donegan, Heavy Reading senior analyst.The Tellabs SmartCore 9200 series is also interoperablewith existing Tellabs products and is managed bythe Tellabs ® 8000 Intelligent Network Manager. Thisinteroperability enables the Tellabs SmartCore 9200 seriesto fit neatly into the network to pave an evolutionary path tohigher Ethernet density, improved cost-per-bit economicsand overall scalability.For example, the Tellabs SmartCore 9200 series pairswell with the Tellabs ® 7300 Metro Ethernet SwitchingSeries for Layer-2 services and applications. Combined withthe newly released Tellabs ® 8609 Access Switch, it canserve as a Layer 2/Layer 3 Ethernet- and TDM-based cellsiteand access solution.With that line-up, Tellabs provides not only a full suite ofmobile solutions, from the cell site all the way to the core,but also a new class of network that enables operators tosupport the smart mobile Internet. •The Tellabs SmartCore 9200series is interoperable withexisting Tellabs products. It fitsneatly into the network to pave anevolutionary path to higher Ethernetdensity, improved cost-per-biteconomics and overall scalability.API: ApplicationProgramming InterfaceIP: Internet ProtocolIPSec: Internet Protocol SecurityTDM: Time Division Multiplexing12 | Tellabs Insight Q4 subscribe to Insight: www.tellabs.com/insight
Time is MoneyAs they migrate to packettransport, mobile operatorsexplore synchronization optionssuch as IEEE 1588v2.By Tim KridelLike the meter in a taxi, the clock signal in a wirelessnetwork ultimately is about money. If the base stationslose timing, handovers will fail and calls will drop,costing the operator revenue.There’s now a new way that timing is money. As mobileoperators migrate to packet transport, many of them areleaving TDM infrastructure at each base station simply toprovide timing.“A lot of carriers are keeping an E1 or a DS-1 at thecell site purely for synchronization,” said Patrick Donegan,Heavy Reading senior analyst. “That’s inefficient. There’sa cost associated with that that you need to get out of thenetwork.”And it’s a big cost.“One E1 can cost several hundred Euros per month,”said Tuuli Sarvilinna, group product manager for theTellabs ® 8600 Managed Edge System. “If you multiplythat by 5,000 or 10,000 base stations, that’s a hugeamount of money.”Why Not GPS?At other operators, the E1s/T1s still carry voice and data,but from both a capacity and financial perspective, theirdays are numbered. Although those operators know they’lleventually have to switch to packet transport, many areunaware of the sync considerations that come with thatmigration.Some operators are considering GPS, which is a maturetechnology. Its drawbacks include the cost of addingGPS equipment to every base station and the lack of GPScoverage in certain areas, such as inside buildings.“Reliance on GPS is also a concern for some operatorsthat point to reports of jamming and the U.S. governmentownership of GPS,” Sarvilinna said.Fortunately other technologies exist that provide thenetwork-wide clock synchronization necessary for taskssuch as handovers. One option is SyncE, which has theEthernet features of IEEE 802.3 and, thanks to the ITU-T,the synchronization features of SDH/SONET.The second major option is 1588v2. The IEEEspecified 1588v2’s protocol suite, including the boundaryand transparent clocks. The ITU-T specifies the servicesavailable both with and without boundary clocks.Vodacom is among the operators that currently useGPS but plan to curb further deployment as part of theirEthernet migration.“Once the access network and core network are basedon IP, the 2 options for access are 1588v2 and/or SyncE,”said Sean Moss, Vodacom principle specialist. “The mainadvantage of 1588v2 is it can supply phase and frequencyover a packet network and is more cost-effective than GPSat every site.”“Any 2 Will Do”The number of base stations worldwide using 1588v2will grow from 48,000 today to 1.3 million by the end of2015, Heavy Reading predicts. That’s an increase from20% of all Ethernet-fed sites today to 43% by 2015.“My assumption is that 1588 will go on to be themost widely deployed [solution] over the next few years,”Donegan said.But that’s not the same as saying that 1588 eventuallywill be the only solution.“A lot of operators will deploy more than one standard,”Donegan said. “There is a view amongst many operatorsthat the right philosophy for this transition is ‘any 2will do.’ There are circumstances where GPS will workperfectly well, but not deep in buildings. I see prettystrong demand for SyncE, as well.”France Télécom Orange is one example.“France Télécom Orange is actively investigating SyncEas a first priority and PTPv2/1588 as a second priority,” saidSébastien Jobert, Orange expert on network synchronization.“GPS and Galileo may also be considered for specificcases.
