Key Market Factors
P2P delivery of multi-media files (BitTorrent), real time streaming (mlb.com) and the viewing video clips (YouTube) today consume 2/3 of broadband traffic.
Fast and efficient delivery of broadband video and games IS the killer application to drive subscriber growth and satisfaction
Most estimates project an 8 fold increase in the volume of bandwidth consumed by broadband households from 2006 to 2010.
Rapid growth of media consumption results in higher bandwidth costs for ISPs without added revenues.

4. PeerApp Solutions
Caching: Most cost effective means to satisfy increase in media consumption (P2P and HTTP streaming).
Media files are highly cacheable due to flash crowd effects
Control: Allows service provider to assert complete control over media delivery and resource allocation (speed, bandwidth, & performance)
Acceleration: Content Acceleration creates a distinct competitive advantage by delivering media at much faster rates to promote subscriber growth and top tier bandwidth packages.
Value-Added Services: Create premium value-added services to participate in the revenue chain associated with accelerating multi-media delivery. 4

There are multiple methods in which one can interface with a service provider’s network in order to provide a service. There are several questions one needs to ask himself beforehand, what is he trying to solve in the short and the long term?, what will be the most effective way in approaching such problems & what is the longevity of such a solution?
Such questions are the reason why connectivity is key. The ability to adapt to needs and the dynamic of the challenge cannot and mustn’t be addressed with a tactical solution, but must be addressed with a strategy, which relies on multiple networking technologies and partnerships. PBR, Redirection, server load balancing represents three methods to comply with the heterogeneous of customer networks and needs, it provides customers with the breath to create a solution that will comply with their unique needs & that will provide them with the ability to introduce support of new protocols, i.e. HTTP video streaming, new P2P networks and what ever the future holds. This distributed design and applying different networking methodologies creates a strong infrastructure for what is to come. For instance, PBR, is a method applied on the SP’s routers, which may take multiple paths. By using high performance DPI switches, we can classify P2P traffic and mark it for caching. The PBR identifies such marks and allows us to deal only with the relevant traffic. This approach makes us ambivalent to the size of the pipes being used by the customer, for example, 10GB pipes, affect the caching servers, the piece that we are interested in the percentage of P2P traffic which is part of this pipe. In order to support 10GB networks the device that needs to handle it is the DPI switch, NOT the cache server.

7. How UltraBand Works: P2P Caching In1
ISP subscribers request file L7
Redirector

Files Cached
Transparently

UltraBand
Switch redirects P2P traffic to UltraBand (by L4 port or L7 signatures)
PeerApp works in spoofing mode – non intrusive and transparent
If the file does not exist in the cache, UltraBand simultaneously caches and forwards the downloaded file
