Juniper Offers Dynamic Bandwidth Allocation for IPTV

Juniper Networks announced a unique Dynamic Bandwidth Allocation capability for its E-series Broadband Services Router aimed at IPTV. Juniper also introduced its SDX Network Resource Manager for the E-, M- and T-series family of IP routing platforms. Both enhancements provide advanced capabilities for managing bandwidth between large numbers of subscribers and multiple sources of video content. As IPTV rollouts gain momentum, Juniper expects there will be at least 3 main sources of content: large number of broadcast TV channels originating at headend facilities; VOD from server farms and Internet-based video content from other parties.

Dynamic Bandwidth Allocation for the E-series Broadband Services Router enables service providers to flexibly distribute bandwidth between the services offered to an individual subscriber. The E-series flexibly and efficiently adjusts service bandwidth based on subscriber activity, which reduces operational complexity and expense. In contrast, other platforms require service providers to pre-provision bandwidth per service.

The Service Deployment System (SDX) is a customizable application for the E-, M- and T-series routers that enables service providers to rapidly create and deploy IP services to hundreds of thousands of subscribers. The Network Resource Manager is the newest SDX feature enhancement and provides end-to-end, policy-based management of video distribution to ensure efficient, quality delivery of service.

The SDX Network Resource Manager performs Call Admission Control (CAC) per video session request to assure the appropriate bandwidth is available to deliver the video stream with the required quality of service as specified by the studio and provider content distribution agreements.

Working with Juniper Networks E-, M- and T-series routers, the Network Resource Manager dynamically constructs Label Switched Paths (LSPs) from the video source to the network edge and automatically re-assigns allocated bandwidth for each video LSP based upon the utilization of the connection. In the event of an outage, the SDX Network Resource Manager can transparently re-route LSPs or acquire the video content from a secondary source without disrupting the viewing experience.

  • Juniper's announced Triple Play customers include KT, China Telecom, RingGold:, SiOL, Telefonica, FastWeb, and Shenandoah, among others.
