The current infrastructure of the Internet is not suited to simultaneous transmission of live events to millions of people. The problem is that a dedicated stream of data must be sent to every single user. With millions of potential users, the simultaneous streams of data will easily congest the Internet. The Net-HD consortium will develop a new technology that be able to increase the effective bandwidth of the network using Video adaptation, Multi Layer Cache and P2P networks without increasing the physical links.

1. Background

Video on the internet has become an integral part of the 'User Internet Experience' today. There has being unprecedented growth in video related bandwidth consumption over the past few years. According to Cisco, by the year 2012, internet video and file sharing via P2P will consume 85% of the consumer band width.

As on today, 80% of the video viewed by consumers in Israel, comes in as 'Over the top content' content, mostly from Europe. Video related data consumes expensive OTT band width. Rise in High definition (HD) video content will add to current infrastructure limitations.

Such rapid rise in internet video bandwidth consumption will have major implications on current ISP business models. The current infrastructure will not be able to support such a rise in bandwidth consumptions.

Thus ISP will need to adopt new techniques in order to cope effectively with this change in demands.

2. Research Objective

Research objective of the Net-HD group are as follows:

• ISP cannot cope with rapid increase bandwidth consumption by internet HD video. We will concentrate on video content using various streaming protocols
• User friendly experience with internet HD video
• Substantially lower 'Over the top (OTT)' bandwidth consumption. This will reduce ISP expenditures.
• As a result of increase in Internet video consumption, there is bandwidth load in the Interconnect layer. BW in the higher layers is limited and expensive
• In near future, substantial increase in internet HD video is expected.

In our research we aim to reduce BW consumption in higher layers like 'Interconnect' layer and 'core' layer. Thus reduce ISP expenses.

3. Principle Research Solution

MLC related research objectives -

• Develop an optimization algorithm that uses certain aspects from the concept of 'caching' and 'multicast' transmission. These concepts will be modified in order to reduce BW consumption in higher layers like 'Interconnect' layer and 'core' layer.
• Substantial part of TV transmission via internet is in the form of live streaming. For example: news or sports events. Thus we will concentrate on streaming technologies only.
• 'Partial streaming' technologies will be used in our research.
• Technology such as breaking live stream media packets into small packets and sending transferring them as HTTP files will be considered. This technology is currently used by 'movenetworks' and 'Microsoft Smooth Streaming'. In addition, 'Adobe – FLV' file format will also be considered.
• Machine learning techniques will be applied in order to predict and determine the video content that will be brought to ISP local network.
• P2P protocol will be simultaneously used for sharing video content within ISP network.
• Optimization of current caching systems

Internet network topology will be modified. No new protocol will be suggested in this research.
