Allied Telesyn Announces 10G Modular Layer 3+ QoS Switching Platform.


SAN JOSE, Calif. -- AT-9924TS Provides 24 Gigabit Ports, Dual 20Gbps Expansion Bays with Multiple Interface Options and Dual Redundant Power Supplies in a 1RU Form Factor

Allied Telesyn, a global provider of secure Ethernet/IP access solutions and an industry leader in the deployment of IP Triple Play networks over copper and fiber infrastructure, today announced the introduction of the AT-9924TS to its line of IPv6-enabled 10/100/1000T Layer 3+ QoS switch solutions. Designed for high-performance enterprise and service provider networks that require rich QoS, hardware resiliency and greater media flexibility, the 9924TS is the most flexible small form factor Layer 3 Gigabit switch solution on the market today.

The AT-9924TS is a modular 1RU switch with 24 fixed 10/100/1000T ports and two 20Gbps capacity expansion bays that currently support SFP, 10/100/1000T or 10GbE XFP modules. This modular design enables network operators to deploy a single switch solution in multiple configurations throughout the network and to add further performance capability to installed switches when required. Front-to-back cooling and support for jumbo frames also make the AT-9924TS the ideal platform for data center server applications and high-performance IP SANs using iSCSI technology.

The AT-9924TS is shipping now with a list price of $8645.

"10G performance, Layer 3+ QoS and resiliency are the drivers behind the 9924TS," says Philip Yim, Allied Telesyn's executive vice president of marketing and product development. "This switch offers network operators a remarkably capable solution to today's demanding high-performance environments. Rich functionality, advanced QoS capability and configuration options combine to make the 9924TS in particular and the 9900 series in general the industry's most compelling Gigabit Layer 3 switch solutions."

The AT-9924TS joins two other models in the 9900 switch series. The AT-9924T is a 24-port 10/100/1000T switch with four additional SFP ports. The AT-9924SP is a 24-port all SFP Gigabit platform for optimum port flexibility in mixed cabling environments. All 9900 series switches offer an enhanced feature set and available hardware redundancy at an industry-leading value point.

The QoS feature set of the 9900 series is unsurpassed, with support for all the key standards including TOS, and DSCP DSCP Defense Supply Center Philadelphia (US DoD)

, queue shaping with RED or simple tail drop, weighted round robin, and strict priority scheduling. Additional and exclusive per-flow QoS mechanisms offer application and service specific metering mechanisms.

The 9900 series is particularly well suited to networks with a planned migration from IPv4 to IPv6. All 9900 series switches are IPv6 capable out-of-the-box. Spurred on by the hot IPv6 network market in Europe and Japan, the 9900s are among the first non-chassis switches available that provide hardware-based IPv6.

The IPv6 support capabilities of the 9900 series perform equally well with IPv4. Layer 3 capabilities including RIP (Routing Information Protocol See RIP.

), 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.  (Open Shortest Path First), 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  (Internet Group Management Protocol (protocol) Internet Group Management Protocol - (IGMP) An extension to the Internet Protocol, used by IP hosts to report their host group memberships to immediately-neighbouring multicast routers.

) and 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.  (Distance Vector Multicast Routing Protocol The Distance Vector Multicast Routing Protocol (DVMRP) is used to share information between routers to transport IP Multicast packets among networks.

It is based in the RIP protocol to forward packets: the router generates a routing table with the multicast group that

The units also support VRRP (Virtual Router Redundancy Protocol Virtual Router Redundancy Protocol (VRRP) is a non-proprietary redundancy protocol described in RFC 3768 designed to increase the availability of the default gateway servicing hosts on the same subnet. ) to synchronize routing tables of multiple devices. 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).  (Border Gateway Protocol Border Gateway Protocol - (BGP) An Exterior Gateway Protocol defined in RFC 1267 and RFC 1268. Its design is based on experience gained with Exterior Gateway Protocol (EGP), as defined in STD 18, RFC 904 and EGP usage in the NSFNet backbone, as described in RFCs 1092 and 1093. ) is also supported.
