Laurel Positions its Edge Router for Triple Play

Laurel Networks unveiled a "drop-in" IP Video Routing Solution that positions its ST200 broadband services router for large scale IPTV and VOD deployments. The rollout includes the introduction of two new line cards that significantly increase the Ethernet density of the company's ST200 broadband services router. These include an Ethernet-optimized network processing blade (NPB-E) that provides 10 Gbps wire-speed performance (not over-subscribed) and a new high-density 10-port Gigabit Ethernet physical interface (PHY) card, which brings port density of the ST200 to a maximum of 80 Gigabit Ethernet ports (line rate), allowing direct connectivity to large numbers of Ethernet-based DSLAMs and OLTs.


The new hardware supports the subscriber management, quality of service and security features needed to deliver IPTV, video, voice, interactive gaming, and other "on demand" services to subscribers. Specific capabilities include:

  • Wire-speed multicast and unicast performance


  • Guaranteed QoS with priority and weighted queue servicing, which enables any mixture of voice, video, and data traffic on a single port


  • Enhanced security to prevent source IP and source MAC address spoofing and block unauthorized sources from the video domain.


  • Seamless bandwidth expansion and link protection via the IEEE 802.3ad standard.


  • Support for IEEE 802.1Q VLAN tagging as well as Q-in-Q (VLAN stacking) to facilitate more scalable Ethernet aggregation and enforce secure, dedicated connectivity to the subscriber.


  • Both cards are in trials during 2Q, with general availability scheduled for 3Q 2005.


The Laurel IP Video Routing Solution also features the latest release of Laurel's ShadeTree system software. Included in the new ShadeTree 3.2 release is support for automated discovery, authentication, and network configuration of Ethernet home media devices such as IPTV set-top boxes. It also enables non-stop forwarding for multicast traffic - even in the event of primary control processor failure.

  • Last month, Laurel Networks announced that Grande Communications had selected its ST50 Broadband Routing Platform to support a large-scale rollout of fiber-to-the-home in locations across Texas. The Laurel ST-series broadband platform provides the edge routing functionality for delivering advanced services such as VoIP, video-on-demand and IP VPNs.
