LANNET ties its 1.28 gibabit LANswitch to FDDI backbones with FDDI switch module; LANNET's MultiNet Switching Hub now supports 128 switched Ethernet connections, switched 100BASE-T for servers, and switched FDDI for backbone links; Switched Token Ring and ATM on the way.IRVINE, Calif.--(BUSINESS WIRE)--March 13, 1995--LANNET Data Communications data communications, application of telecommunications technology to the problem of transmitting data, especially to, from, or between computers. In popular usage, it is said that data communications make it possible for one computer to "talk" with another. Ltd., a leading supplier of scalable switching hubs for enterprise computer networks, Monday announced that organizations with networks based on FDDI (Fiber Distributed Data Interface) Often pronounced "fiddy," it was a LAN and MAN access method that had its heyday in the mid-1990s. FDDI was an ANSI standard token passing network that transmitted 100 Mbps over optical fiber up to 10 kilometers. backbones can now attach LANNET's 1.28 Gigabit-per-second MulitNet(r) switching hubs directly to FDDI with a new plug-in module called the LANswitch(r) LSF-100. FDDI Joins LANNET's Scalable Protocol-Independent Switching Architecture "The LANswitch LSF-100 module lets network managers create a switched 100Mbps data pipeline from the FDDI backbone into scalable Gigabit-speed switching hubs in buildings or floors throughout the enterprise," said Avi Fogel, executive vice president of global marketing and business development at LANNET LANNET Large Artificial Neuron Network . "After data is transported on the FDDI backbone, the MulitNet hub can switch it to Ethernet and 100BASE-T, with ATM and Token Ring A local area network (LAN) access method developed by IBM. Conforming to the IEEE 802.5 standard, Token Ring uses a token ring access method and connects up to 255 nodes in a star topology at 4, 16 or 100 Mbps. switch modules following this year. With up to 128 switching connections, plus multiprotocol cell switching Using cell switches to forward fixed-length packets in a network. Contrast with frame switching. See ATM. , we're delivering the kind of advanced enterprise switch architecture that organizations can buy and won't outgrow outgrow verb To change the relationship with a condition or structure by dint of ↑ age or size; while children outgrow clothing, and certain behaviors, they rarely outgrow diseases–eg, asthma ." Virtual LANs Cross the FDDI Campus Backbone The LANswitch LSF-100 module extends Virtual LANs (VLANs) across FDDI. Multi-hub VLANs give network managers the ability to assign any station in the enterprise to any logical network regardless of physical location through software control. LANNET FDDI Switching Applications The LANswitch LSF-100 can be used for three distinct switching applications on the FDDI backbone: o The FDDI network is used to transport traffic between switched Ethernet An Ethernet network that is controlled by a switch instead of a shared hub. The switch cross connects all clients, servers and network devices, giving each sending-receiving pair the full rated transmission speed. segments. Virtual LAN information is shared between switching hubs, extending user-defined segments across the campus. o The FDDI network is used to cluster high-performance servers. Selected servers can also be connected to 100BASE-T using LANNET's LANswitch LFE-100 module. o The MultiNet switching hub with multiple LSF-100 modules replaces the shared media FDDI backbone with a high-speed FDDI switch at the center of the network. Dedicated 100 Mbps FDDI connections extend to department routers throughout the campus, multiplying backbone performance and allowing network diameters up to 4 kilometers without any re-cabling. LSF-100 Expands LANswitch Module Family The new LSF-100 joins LANNET's already shipping family of Ethernet and 100BASE-T LANswitch modules. LAN managers can plug in an LSF-100 next to any of LANNET's switching modules to connect MultiNet hubs to existing FDDI backbones. -0-

The probe can monitor traffic and set an alarm when a certain condition occurs. It can be used to periodically audit traffic as well as gather statistics that are sent to the management console. modules, and bridge and routers modules LANswitch LSF-100 Specifics The LANswitch LSF-100 is an Ethernet-to-FDDI translation bridge with an internal interface to the MultiNet hub's 1.28 Gbps cell switching bus and standard FDDI MIC front panel connectors in DAS or SAS (1) (SAS Institute Inc., Cary, NC, www.sas.com) A software company that specializes in data warehousing and decision support software based on the SAS System.

The SAS version has a single MIC connector (Medium Interface Connector) A fiber-optic cable connector that handles a pair of cables. The design of the plug and socket ensures that the polarity is maintained (transmit and receive cables are in correct order). ; the DAS version has dual MIC connectors -- both support standard FDDI multimode fiber cabling at distances of up to 2 kilometers. The LSF-100 module supports SMT (1) (Surface Mount Technology) See surface mount. (2) (Station ManagemenT) An FDDI network management protocol that provides direct management. Only one node requires the software. SMT - Station Management version 7.2 and can be managed by SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol.

A Switching Architecture That Proves Its Unbeatable Performance The MultiNet switching hub and LANswitch modules shattered the all-time data throughput record in performance testing at the Harvard University Internetworking Laboratory directed by Dr. Scott Bradner. Utilizing only one-fourth of its total available 1.28 Gbps bandwidth, MultiNet forwarded 446,400 packets per second without dropping a single packet, more than double the throughput of any switching hub previously tested. Full results from LANNET and competitors are available on the InterNet from Harvard Internetworking Laboratory at TEST_LAB(at-sign)NDTL.HARVARD.EDU. Pricing and Availability The LSF-100 LANswitch module is priced at $9,795 in North America for the SAS version; $10,595 for the DAS version. Both are scheduled to ship in May 1995.
