net.com Announces "Qserv" TR-059 Capabilities for its B-RAS

net.com announced a new release of its SCREAM broadband remote access server (B-RAS) featuring "Qserv" technology for delivering advanced QoS capabilities over existing plain old DSL (PODSL) lines. Net.com's QServ technology complies with The DSL Forum's TR-059 specification for multiple tiers and IP classes of service over DSL while using a single ATM virtual circuit. In essence, Qserv tightly couples the IP and ATM QoS/CoS data planes.



The company said independent testing with carrier customers has demonstrated the SCREAM's ability to enforce QoS for a 2.6 mbps streaming video to an IP-based set top box and a 1 mbps stream to a "walled garden" content farm while maintaining best effort Internet access to an ISP, all over a single ATM VC.



net.com's SCREAM platform includes an integrated ATM switch, as well as IP and MPLS backhaul capabilities. The platform offers 5 levels of traffic shaping in a single ATM VC. The new 3.0 release of the platform also has he Cisco IOS routing engine running on SCREAM 3.0.



Bezeq, the incumbent carrier in Israel, is using the platform for valued-added DSL services, including a new "walled garden" ISP offering and network based security. http://www.net.com
