Juniper Offers "Liquid LSPs" and MPLS Point-to-multipoint (P2MP) Broadcast Video Capabilities

Juniper Networks announced a series of product enhancements aimed at improving video transport throughout an IP network core. The new features include several enhancements to MPLS-based point-to-multipoint (P2MP) broadcast video distribution and new capabilities for the company's SDX-300 Service Deployment System.

Juniper is also introducing "Liquid LSPs", a solution that leverages the SDX-300's open APIs to ensure efficient network handling of video-on-demand content. Using an open API, third-party video serving platforms communicate with the SDX-300 and Juniper routers to map the best possible path between subscribers and content sources to increase network efficiency, while also preserving high levels of video quality. The Liquid LSP feature also supports Fast Failover capability for split-second failover, ensuring the quality and reliability of video services even in times of network congestion and equipment failures.

Juniper said that by enabling the dynamic activation and modification of LSPs between video serving locations, Liquid LSPs enable providers to serve videos from multiple locations, reducing costs and increasing network design flexibility.

SeaChange International is the first to integrate its open IPTV platform with Juniper's Liquid LSP capability.

Juniper has also implemented a number of enhancements to further extend the point-to-multipoint (P2MP) capabilities of JUNOS. P2MP is
an MPLS-based multicasting solution that provides efficient, scalable and reliable delivery of broadcast TV traffic across the backbone. P2MP enables providers to leverage the simplicity of MPLS for core video distribution without adding new protocols or increasing operational complexity. The new features include the extension of constrained shortest path first (CSPF) functionality to P2MP LSPs, which enables the network to automatically determine the most efficient path through the network for a given video stream. This allows a few super head-ends to service many remote video sites
over long distances while assuring delivery quality of the broadcast TV channels.

Juniper is also announcing enhancements to BGP (Border Gateway
Protocol)-based VPLS (Virtual Private LAN Services) that simplifies the scaling of metro video distribution networks.

"Much of the attention around IPTV to date has been focused on the network edge, but efficient delivery of IP-based video through the core IP network is just as important to our customers," said Shailesh Shukla, vice president of service provider marketing and partnerships, Juniper Networks.
