The Nortel NetworksPassport 8600Nortel Networks Passport 8600 RoutingSwitch provides wire-speed switching androuting with carrier grade reliability. It is akey component of the Nortel NetworksOptical Ethernet solution deliveringGigabit Ethernet performance and Qualityof Service (QoS) for business criticalapplications and services such as InternetTelephony. The Passport 8600 provides128 Gbps of switching capacity, a varietyof 10/100, Gigabit Ethernet, Packet overSONET and ATM ports, and a highperformance infrastructure for flexiblerouting and switching.FeaturesThe Alteon WSM is an integrated WebSwitch blade with 4 external, non-blockingWeb Switching multi-speed ports, availablewith both 1000BASE-SX and RJ-4510/100BASE-T connections. The blade ismanaged from within the 8600 operatingenvironment, while a maintenance portprovides additional debugging capability.The blade occupies one I/O slot in the8600, and up to eight can be installed in asingle system.High AvailabilityThe Alteon WSM is designed to enable ahighly available data center with no singlepoint of failure. Central to that design isthe use of the Virtual Router RedundancyProtocol (RFC 2338), ensuring fast failoverin the event of failure. The Alteon WSMcan operate in active/active, active/standby,and hot standby modes to ensure non-stopoperations while providing parallelprocessing of Web traffic. The 8600platform also offers a long list of carriergrade features, including redundant fabricswith sub-second failover, redundant CPUs,redundant power, and a CO grade chassis.Unique DistributedProcessing ArchitectureDelivers Performanceand ScalabilityLeading the industry, the Alteon WSMenables the processing of entire Websessions at blazing speeds using Layer 4through 7 information such as TCP portnumbers, URLs, HTTP headers, andHTTP cookies. New capabilities alsoenable the WSM to support Layer 7regular expression, and to performswitching based on a combination of Layer7 attributes, such as URL plus host header,URL plus cookie, or cookie plus hostheader. Each Alteon WSM can process upto 296,000 sessions per second per modulethrough the use of Nortel Networks next-generation Alteon network processingASIC, the WebICTM. Performance isscalable up to 2.4 million sessions persecond. The Alteon WSM features 10purpose-built WebICs, 20 RISC proces-sors, and 80MB of memory for processingsession traffic. For data centers performingeven more compute-intensive tasks, such asthe decryption and encryption of SSLtraffic, the Alteon WSM is easily integratedwith Nortel Networks' revolutionaryAlteon Integrated Service Director(iSD) platform.Alteon WEB OS –The Industry-LeadingTraffic and ApplicationControl SoftwareThe Alteon WSM supports all of NortelNetworks best-in class Alteon Web OSapplications. Server Load Balancingoptimizes existing servers, enables trans-parent additions, and features linearperformance increases as more servers areadded. Firewall Load Balancing extendsthese benefits to firewalls as well, whilecomprehensive health checking ensuresthat all devices are operating at peakefficiency. Web Cache Redirection enablesthe use of transparent Web caches whereverpossible, and improves performance bymoving them out of the data path.Innovative Content Intelligent Switchingallows traffic management based oncontent attributes including HTTPheaders, HTTP cookies, and URLs as wellas combinations of them, enabling session-level persistence, virtual hosting, and thebest use of resources. BandwidthManagement features enable the creationof guaranteed or preferential bandwidthservices based on Layer 7 attributes, whileGlobal Server Load Balancing directs theuser to mirrored content. Unlikecompeting products, the most current WebOS software release is offered simultane-ously on both the stackable and modularproduct lines. This brings the WSM all thebenefits of a Web OS field-hardened inover 10,000 customer sites.The Alteon WSM also adds uniquefeatures to enable new, highly profitableservices. One such service opportunityis streaming media using Real TimeStreaming Protocol, or RTSP. The AlteonWSM is able to intelligently switch boththe control and media sessions to the sameRTSP server or cache, and maintain sessionlevel persistence. Another serviceopportunity can be seen in the widespreadpopularity of wireless Internet access.The Alteon WSM is able to intelligentlyload balance WAP gateway servers,adding scalability, reliability, healthchecks and unparalleled persistence towireless operations.Web OS also provides the functionality toassist in intrusion detection system scala-bility, performance and availability.Intrusion Detection Server load balancingallows multiple intrusion detection serversto operate in parallel and ensures that allsessions entries are maintained and sent tothe same ID server. This solves the inheritlimitations of Intrusion Detection Systems,which include lack of scalability andthroughput, by ensuring server availabilityand persistency via health checking andsophisticated redirection filters.
