Allied Telesyn Introduces Core Solution; SB4000 Switch Series Combines Powerful Performance With Customizable Modules for Ultimate Control of Network Traffic.Business Editors BOTHELL, Wash.--(BUSINESS WIRE)--Jan. 21, 2003 Allied Telesyn, Inc. (www.alliedtelesyn.com), a world leader in network technologies for the access edge, today unveiled its most powerful switch solution, the SB4000 series of modular, multi-layer Fast Ethernet and Gigabit Ethernet switches. Now, from the core to the desktop, Allied Telesyn offers a one-stop source for affordable, high performance switches and routers to deliver efficient and secure networks. The SB4000 series is designed to compete head-to-head with traditionally recognized players at the network core, such as Cisco Systems, Extreme Networks and Foundry Networks. Available in a four or eight slot chassis configuration with a number of customizable modules, these switches are well-suited for deployment in very large, distributed networks or for future-proofing smaller networks. "With these new medium and high-density chassis products offering customers a significant price/performance advantage over the competition, Allied Telesyn is demonstrating key capabilities in the end-to-end solutions market," says James Mustarde, Vice President of Sales & Marketing. "Allied Telesyn customers can now deploy advanced Layer 3 switching from the core of their networks to the access edge and further with one of the industry's most comprehensive line-ups." The four slot chassis, AT-SB4104, features 4 line card slots and supports up to 192 ports of 10/100TX (RJ45), 128 ports of 100FX, 32 ports of 1000X or combinations. The eight slot chassis, AT-SB4108, offers eight line card slots and supports up to 384 ports of 10/100TX (RJ45), 256 ports of 100FX, 64 ports of 1000X or combinations. Both switch configurations seamlessly meet the demands of education, service provider and enterprise networks. The SB4000 series provides uncompromised packet switching performance, enabled by a non-blocking switch fabric delivering Layer 2 and Layer 3 IP/IPX data at wirespeed on all ports regardless of packet size. With advanced QoS, up to 128Gbps switching capacity and MAC/IP addresses scalable to 232,000, the SB4000 switches boost network performance by eliminating congestion The condition of a network when there is not enough bandwidth to support the current traffic load. congestion - When the offered load of a data communication path exceeds the capacity. . The powerful, market-leading Quality of Service mechanism allows traffic shaping in a highly programmable manner based on physical layer to Layer 4+ packet characteristics. The resulting 128 different Classes of Traffic enable flexible policy-based Service Level Agreements with independent latency and 64Kbps-increment min/max bandwidth guarantees. SB4000 units use IEEE 802.1p, DiffServ, Layer 4 filtering and RSVP (ReSerVation Protocol) A communications protocol that signals a router to reserve bandwidth for real time transmission. RSVP is designed to clear a path for audio and video traffic, eliminating annoying skips and hesitations. along with sophisticated hardware-based switching to deliver a rich QoS capability for the ultimate control of network traffic. SB4000 switches lead the market with an extensive suite of Layer 2, Layer 3 and Layer 4+ features including static routing, RIP/RIPv2, OSPF (Open Shortest Path First) A routing protocol that determines the best path for routing IP traffic over a TCP/IP network based on distance between nodes and several quality parameters. , BGP (Border Gateway Protocol) The routing protocol that is used to span autonomous systems on the Internet. It is a robust, sophisticated and scalable protocol that was developed by the Internet Engineering Task Force (IETF). 4, OSI (1) (Open System Interconnection) An ISO standard for worldwide communications that defines a framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, proceeding to the IS-IS (Intermediate System to Intermediate System) An ISO protocol that provides dynamic routing between routers. IS-IS is an interior gateway protocol (IGP) and was the first comprehensive link state protocol. routing protocols; IGMP (Internet Group Multicast Protocol) The protocol that governs the management of multicast groups in a TCP/IP network. To sign up for a multicast group, a Host Membership Report is sent by a user's machine to its nearest routers, which forward that data to , IGMP Snooping, DVMRP (Distance Vector Multicast Routing Protocol) The first popular routing protocol to support multicast. Stemming from RIP and used in the Internet's Mbone (multicast backbone), DVMRP allows for tunneling multicast messages within unicast packets. , PIM-SM PIM-SM Protocol Independent Multicast-Sparse Mode (RFC 2362) and PIM-DM PIM-DM Protocol Independent Multicast-Dense Mode multicast protocols; IP, IPX (Internetwork Packet EXchange) The network layer protocol in the NetWare operating system. Similar to the IP layer in TCP/IP, it contains a network address and allows messages to be routed to a different network or subnet. and AppleTalk, 4k VLANs, Load Balancing and flexible Link Aggregation. These features are bundled to suit the needs of a standard application or an advanced architecture. The SB4000 series offers many advanced features to ensure network security: Stateful Inspection, wirespeed filtering, MAC control, Port-Intrusion Detection, Access Control Lists, Port Security, Secure Shell (SSH (Secure SHell) A security protocol for logging into a remote server. SSH provides an encrypted session for transferring files and executing server programs. Also serving as a secure client/server connection for applications such as database access and e-mail, SSH supports a ) and Secure Socket Layer (SSL (Secure Sockets Layer) The leading security protocol on the Internet. Developed by Netscape, SSL is widely used to do two things: to validate the identity of a Web site and to create an encrypted connection for sending credit card and other personal data. ). With 4078 VLANs available -- which are Port, Protocol, Subnet and MAC address based -- security across VLANs is assured. SB4000 switches provide a number of features to maximize network availability. Switch controller redundancies, VRRP (Virtual Router Redundancy Protocol) A protocol for switching to a backup router in the case of failure. Two or more routers are set up with VRRP, and one is elected the "master. , Port Trunking and RSTP See RTSP. minimize downtime. Additionally, the mechanical system built into SB4000 includes a load sharing N+1 power supply, completely eliminating downtime. The hot-swappable switch controllers, power supplies, line cards and redundant cooling fans ensure this core network device keeps networks alive 24 hours a day/7 days a week. The SB4000 series includes a comprehensive set of features allowing simple configuration and control without compromising flexibility. The switches have a built-in DHCP server; TFTP (Trivial File Transfer Protocol) A lightweight version of the FTP protocol that has no directory browsing or password capability. Employing UDP rather than TCP for transport, TFTP is typically used to transfer firmware upgrades to network equipment such as for image and configuration downloads; Network Time Protocol client and server capabilities; advanced, customizable triggers with an email client; standard CLI and highly intuitive GUI device configuration tools; and full SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc. and MIB (1) (Management Information Base) The hierarchical database used by the simple network management protocol (SNMP) to describe the particular device being monitored. MIB objects are identified using ASN.1 syntax. See SNMP, RMON, OID and ASN.1. support for network management.
