Embracing New Internet Transport Technology

World Multicast, Inc. (WMI) is well aware that the amount of data traveling across the public Internet is growing at an unprecedented rate, and that bandwidth, or the lack thereof, is becoming an extremely critical issue. The problems associated with Internet congestion must be addressed if crucial infrastructures are to continue to function in an effective and dependable manner. It is not surprising that industry research shows viewers of streamed content over the Internet are not fully satisfied with their experience. For operators to manage mounting costs and bandwidth limitations, their customers often must deal with extended buffering times, poor video quality and system failures. Regardless of the significant challenges facing streaming media technology, it is still destined to become Television’s next delivery model. To remain cost effective and retain sufficient bandwidth reserves, it is imperative for the broadcast industry to embrace emerging technologies that are designed to address both today’s streaming demands and the inevitable expanding needs the future will bring. The sooner more comprehensive transport technologies are adopted, the sooner the industry will begin to realize greater infrastructure efficiencies and increased financial returns.

Unicast Streaming (one-to-one): Unicast transport technology was not engineered to meet today’s massive video demands. One of the main drawbacks of Unicast is that it requires the sending of a separate stream to each and every end user, which often consumes more bandwidth than is available. This congestion can cause serious problems including system crashes, unpredictable service levels, poor quality and slow connection speeds. It is also increasingly clear that Unicast technology may not be capable of supporting the full-scale deployment of higher resolution television, such as 4K. Certainly, future Internet transport demands will surpass Unicast’s inherent capacity limitations.

SMARTcast Streaming (one-to-many): One significant advantage WMI’s SMART technology has over Unicast is its ability to send a single stream to a massive number of end users, simultaneously. With SMART, the large-scale distribution of linear content can be very efficiently sent over existing Internet infrastructures, resulting in exponentially lower transport and systems costs. SMART’s comprehensive platform delivers unsurpassed quality, reliability and accountability. SMART also addresses serious cyber security vulnerabilities that continually threaten the Internet. These are some of the reasons why World Multicast is poised to play a significant role in online video growth.

Internet traffic depends on a complex association of previously recorded data objects. This document defines an association mechanism that provides an extensible and scalable protocol to access persistent data. The mechanism is called the Discovery Protocol for a Directory of Persistent Objects (DP-DPO).

A good example of IT manager’s resistance to add additional tables to their routing infrastructure is the lack of native support for MSDP on the Internet2.

Providing an IPV6 compatible Discovery Protocol that could efficiently discover the sources for IP Anycast and IP Multicast would be a good initial use for the Directory of Persistent Objects. Internet Message Processors could retain (cache) the more frequently used persistent objects, hence increasing performance without maintaining a separate table for MSDP.

This powerful platform, which includes a sophisticated bidirectional reporting mechanism, can be used as the backbone for transporting virtually any type of data, including high-definition video, through the use of existing Internet protocols and infrastructures.

The foundation of Worldcast’s technology is a patented middleware solution called SMART. This platform is capable of transporting virtually any type of data (including high-definition video) to a mass audience with unprecedented efficiency and quality. SMART accomplishes this by using a comprehensive suite of integral components developed by World Multicast, Inc. The following information provides a brief description of each of these components.

SMARTtransport enables a multipoint network to transmit data in a manner that not only greatly enhances bandwidth efficiencies, but that is also highly secure, reliable and scalable. This platform can be used as the backbone for the transport of Multipoint Video, Stock Ticker Data, C2 Communications, Electronic Medical Files, SCADA (Supervisory Control and Data Acquisition), etc.  SMARTtransport also provides a distributable mechanism for usage accounting.

This is where a SMARTcast begins. The SMARTencoder server incorporates two components. The first module contains the actual video encoder software that constructs multiple bitrate streams, using H.264 Codec compression. These encoded streams are sent locally, via Real Time Messaging Protocol (RTMP) to the second SMART component called the “Tunneling Data Master”(TDM). The TDM adds Forward Error Correction (redundant data) and integrates the SMART Header data that allows SMART packet replacement and encryption to be incorporated into the stream. The TDM software also creates the Multipoint transmission that is “tunneled” to the network interfaces, which are routed publicly to the SMARTmaster. Importantly, SMART is able to automatically tunnel where native Multipoint is not available, and then continues using native Multipoint where it is available.

The SMARTmaster server also incorporates two integrated components. The first is Worldcast’s “Tunneling Data Client” (TDC). The TDC is a software application that continuously monitors downstream client-side data and reconstructs packets that have been lost or damaged while in transit from the TDM and network interfaces. The second component uses Worldcast software to reencrypt the data and retranslate it into SMART Multipoint protocol. The SMARTmaster also  provides packet replacement, which adds reliability to the rest of the SMART MDN and is integral to the logging of SMART Analytics.

The SMARTrepeater provides multi-tiered encryption that obfuscates the system backbone of public or private networks from unauthorized users. SMARTrepeater software translates the stream from the SMARTmaster and re-encrypts and rebroadcasts it to multiple new IP Addresses and Ports, which are isolated and hidden from the end user. A version of this security mechanism is also incorporated into the network by the SMARTencoder, during the ingest process at the headend. The SMARTrepeater is a close-ended, undetectable system that adds layers of protection that insures heightened security for the backbone. The repeater function also enhances scalability by allowing packet replacement closer to the SMARTendnodes.

The SMARTendnode component redistributes the HLS adaptive stream to the end users. These edge servers also help to isolate a private network (backbone) from the public Internet and reduces transmission costs, while enhancing security and quality of service. SMARTendnodes utilize integrated software to decode encrypted transmissions received from the SMARTmaster, or SMARTrepeater. These endnodes provide automatic, low latency, client-side packet replacement and build specific video formats that are dynamically cached and forwarded to the end users. Multiple SMARTendnodes and custom geolocation load balancing capabilities are employed to spread the user load. Additionally, SMARTendnodes incorporate Accelerated Buffering Technology (ABT), which provides unprecedented channel switching speeds by reducing buffering times.

The SMARTvisualizer is a powerful tool, that allows an operator to perform comprehensive real-time monitoring of network conditions between the SMARTencoder and the SMARTmaster. Through remote Secure Shell (SSH) terminals, an administrator can “visually” detect various anomalies that may occur on specific interfaces. This information can be used to quickly analyze and resolve various network problems.

The SMARTadministrator is a management tool, that allows network operators to continually monitor and control an extensive system of cloud based SMARTendnode servers in real-time. This tool features a graphical user interface, which displays the number of clients that are connected to the SMARTendnodes and the amount of bandwidth that is streaming to and from each server. The SMARTadministrator is also used to configure new servers that have been added to Worldcast’s geolocation database system.
