  • How can an R&E network afford to build an advanced network?Use the obvious strategy of obtaining donations from providers and equipment vendors and the use of grantsMake more efficient use of the available (scarce) resources - MORPHnet

  • Production and experimental infrastructure(MORPHnet concept) and their use

  • What does a user want from an optical network?An end-to-end path (lightpath) where the endpoints are not defined by the limits of a single carriers network

  • Lightpathsa lightpath is defined to be a fixed bandwidth connection between two network elements, such as IP routers or ATM switches, established via the optical networkIetf draft on lightpath attributes

  • Lightpath attributesIt is assumed that a lightpath will have a number of attributes that describe it such as framing, bandwidth, etcCanarie asserts that across a given AS a lightpath may be abstracted to look like a single (possibly blocking) cross-connect switch interface.

  • working examples of LightpathsAll Optical wavelength on WDM systemSONET channelPoint to point ethernetATM CBR circuitMPLS LSR with defined QoSFiberchannelSMPTE 259G.709 (Digital Wrapper)

  • ProblemsIntra-domainProvisioning of network capacity across network elements within an ASO&MInter-domainProvisioning of network capacity across multiple ASsO&MIn this environment the user has to handle performance and fault management

  • LightpathCarrier ACarrier BCarrier CUser desires red path but must negotiate and manage provisioning of green, orange, and blue paths

  • ApproachesMethods of defining, provisioning, and modifying existing services within a management domainG.ASTNGMPLSMethods of linking paths from multiple domainsUCLPNon-traditional techniques for provisioning capacity between endpointsOBS/JIT

  • GMPLSGeneralized MPLS signaling to identify the following path types:Traditionally statistically multiplexed labeled paths such as ATM or EthernetTime division multiplexed paths such as SONET where timeslots are the labelFrequency division multiplexed services such as wavelengths where frequency is the labelSpace division multiplexed services such as fibers in a bundle where position in the real world is the label

  • UCLPCanarie is developing a system including protocols and directories and registration mechanisms Addresses interdomain issues:Registration of available path componentsDirectory service for those componentsProvisioning of end to end path which could use intra-domain tools such as GMPLS

  • JIT/OBS view of Optical Network DilemmaGoal: Lower cost by:Minimizing OEOCreating larger transparency islandsBut:Dedicated is overkill (expensive)Low speed apps. need fine grain mux capabilityAnd:Existing fine grain multiplexing today requires electronics hence OEO conversion

  • Technology gapRequires optical buffersImmature, expensive, low densityBuffers in net lead to complexityIP is a COMPLEX protocolHardware implementations only recentlyCreates cost and technology barrier

  • Optical Cell SwitchingTDM dWDMAll wavelengths on fiber switched togetherPluses and minusesSimpler core networkNeed chromatic time correctionRequires frame synchronizationLow utilization of wavelenghtsLucent is major proponent

  • Three Competing Ideas

  • JIT Fundamental ValuesLow latency is first priorityTell and go vs. tell and waitMay sacrifice link utilizationJET and HorizonAggressive protocol simplificationA pox on buffers (optical delay lines)Leads to un-necessary protocol and switch complexitiesLeads to greater link speed and lower latencyKeep data in opticsNo legacy assumptionsResult: high throughput, min. latency and jitter

  • JIT - OBS ApproachSwitched light path network Large all-optical islandNo buffers in data channelAvoids immature device technologyNo buffer overflow in network Data and signaling channel isolationSingle out of band signaling channel per fiberSignaling msgs. undergo OEO, processed by intermediate nodes Network intelligence is concentrated at edgeSIMPLE protocol implemented in hardware

  • ECOnetCreate a confederation of fiber linked NRT projects:BOSnet: MIT Lincoln Labsdark fiber Boston to Washington DCATDNet: Naval Research Lab (& others) dark fiber within the Washington D.C. metro areaECO-South (proposed):MAX/MCNC/SOXDark fiber from Washington to Research Triangle Park and then to Atlanta

  • East Coast Optical NetworkECOnet
