Octoshape and Juniper Networks, Delivering Multicast OTT

White Paper – It’s Time to Rethink What You “Know” About Multicast

But to enjoy these benefits, you have needed to deploy IP multicast protocols on every router in the path. Consequently, IP multicast exists today primarily in small, highly controlled pockets of networks.   However, if you’ve read Juniper Networks’ joint solution brief with Octoshape titled TV Quality, TV Scale, TV Economics via Broadband Multicast, you know that new technologies have emerged which turn yesterday’s truths about IP multicast into nothing more than today’s myths. Unfortunately, the persistence of these myths is preventing you, along with many other service providers, from deploying IP multicast on the broadband side of the network. As a result, you’re missing a huge opportunity to harness the scalability and bandwidth efficiency of IP multicast to deliver video across the Internet to any connected device. You’re also missing opportunities to control traffic loads, conserve bandwidth, offer new services, generate additional revenues, capture bigger market share, and strengthen long-term profitability.

The good news is that tools now exist to break through these barriers and deliver on the promise of multicast. Working together, Juniper Networks and Octoshape have produced a solution which makes IP multicast resilient and reliable, enabling you to deploy it on your best-effort broadband network to support the linear distribution of Internet video service. So forget everything you think you know about deploying multicast—you now have the tools you need to build a deployment model that works.

Finally, You Can Make Multicast Work

This solution knocks down all of the barriers which so far have prevented the widespread deployment of IP multicast. As you know, these barriers include the following assumptions, which may or may not have been accurate:

• Every routing device in the delivery path must support IP multicast, which means that if IP multicast is to be ubiquitous, every service provider must decide to offer multicast service.

• It’s a big challenge to deliver multicast service reliably in the inherently best-effort environment that exists on the Internet today.

• Broadband video transmission requires adaptive bit rate streaming, which multicast lacks.

• Today’s video streaming formats, designed to use progressive download mechanisms, are not inherently multicast capable.

• Interdomain multicast, or multicast peering between Internet service providers (ISPs), requires complex business arrangements and network configurations.

• This is a classic chicken-and-egg problem—which comes first, multicast capable content or multicast capable networks?

To tackle these issues, you need a software solution which basically glues together the video delivery elements in a way that can transparently blend multicast into the distribution chain, but does not require multicast to be everywhere. Using such a solution, you can integrate multicast into your system at your own pace, according to your unique business requirements and, as you deploy multicast, the linear video stream traversing your network simply becomes more efficient.

Octoshape’s client/server-based video distribution technology encodes unicast and multicast video streams using multiple simultaneous sources and user datagram protocol (UDP) transport. As the ecosystem “glue,” the core Octoshape components of the solution perform the following functions:

1. Ingest traditional streaming formats, which are based on Real-Time Messaging Protocol (RTMP) or HTTP, and transform these into a stream for either unicast or multicast reception.

2. Add a unique resiliency layer which enables the video streams to survive over best-effort networks around the world. Consequently, you do not have to provision for quality of service (QoS) or complex resiliency mechanisms in your network to ensure that multicast can deliver high-quality content reliably.

3. Preserve the multi-bit-rate features of new streaming protocols, thereby accommodating various wireless connectivity speeds and giving individual users on different networks operating at different speeds a buffer-free video experience.

4. Transparently blend unicast and multicast data to give the user a high-quality video experience, regardless of whether the network to which the user’s device is connected is multicast capable.
