Expandable Gigabit Layer 3+ switches offer wide-ranging possibilities.

Allied Telesyn, the global provider of end-to-end Ethernet/IP solutions, released AT-x900-24XT and AT-x900-24XS Gigabit Layer 3+ expandable switches. These new additions to the company's portfolio are designed for organisations where high performance network applications are essential, for example in the Service Provider market or the Online Education industry where lectures are conducted through live video.

These switches come with two 30Gbps expansion bays supporting a choice of modules, including a 10GbE port module, a twelve 1GbE port SFP module and a twelve 1GbE (RJ45) port module for port flexibility and application versatility unmatched by any other 1RU Gigabit Ethernet switches on the market. The expansion modules can be used in a variety of configurations to provide tailored solutions that meet wide ranging physical networking requirements. Designed to provide unmatched flexibility, Allied Telesyn's AT-x900-24XT and AT-x900-24XS Layer 3+ switches provide maximu

m Gigabit Ethernet port density in a compact chassis.

Both AT-x900-24XT and AT-x900-24XS comes with 10GbE expansion modules and hot-swappable XFPs that provide high-speed, high-capacity fiber uplinks, with the option of either 10Gbps or 20Gbps uplink capacity to the network core. Moreover, resiliency can be achieved by using two 10GbE modules and MSTP (802.1s) for fast failover on link failure. This is suitable for wiring closet aggregation of gigabit to the desktop links and aggregating gigabit uplinks from other network switches.

Included in these switches is the 150Gbps switching fabric that supports up to two wire-speed 10Gigabit Ethernet ports that is ideal for organisations where high capacity network applications are required. With its 71.4 Million packets per second performance Allied Telesyn's AT-x900-24XT and AT-x900-24XS will guarantee low latency for applications like VoIP, real-time video streaming, multimedia, etc by ensuring wire-speed forwarding of packe

ts.

Besides, an enhanced feature of the high performance switches is the support for Ethernet Protected Switched Rings (EPSR) and 10 GbE modules that allow several AT-x900-24X and AT-x900-24XS switches to form a protected ring with sub 50ms failover. This feature is perfect at the core of enterprise or provider access networks where high performance is needed.

Other useful features include hot-swappable and load-sharing power supplies, full environmental monitoring of PSUs, fans, temperature and internal voltages, with cable fault detection and SNMP traps to alert network managers in case of any failures. Both switches come with an SD memory card socket on the front panel, allowing software release files, configurations and other files to be stored for backup and distribution to other switches.

"The versatility of both switches are an excellent example of the flexibility that Allied Telesyn is known for," observed Allied Telesyn's Deputy Director for Product Mar

keting & Fulfilment in Asia Pacific, Jason Phoon. "The aspiration of the company is to provide quality network equipment that protects our customers' investments and their networks."

Other than the peerless flexibility, AT-x900-24XT and AT-x900-24XS offer Quality of Service (QoS) features that are ideal for service providers' needs to ensure maximum availability of premium services and at the same time manage customer service level agreements. For enterprise customers, AT-x900-24XT and AT-x900-24XS QoS features assure productivity by guaranteeing performance of business-critical applications (including VoIP services), and help to restore and maintain responsiveness of enterprise applications in the workplace.

The comprehensive, low latency QoS features operate at wire-speed to provide flow-based traffic management with full classification, prioritization, traffic shaping and min/max bandwidth profiles. Prioritisation can be provisioned with two rate three colour bandwid

th metering and with burst sizes to improve TCP-IP bandwidth limiting performance. The bandwidth controls enable 1Kbps traffic class resolutions, buffered max bandwidth at egress on all ports and 8 egress queues per port. The low latency QoS is ideal for Voice over IP and real-time media steaming applications.

Except for Allied Telesyn's AT-x900-24XS that will be available in February 2007, Allied Telesyn's AT-x900-24XT is available now in Asia Pacific at all distributors and resellers.
