Building the Cache UltraBand P2P caches are deployed empty of content ISP subscriber makes a download request or is uploading a file Layer 7 redirector transparently redirects P2P traffic to UltraBand cache If file is not already in cache, UltraBand simultaneously acquires the file, caches and forwards the file to ISP subscriber or Internet user

Downstream Cache Out ISP subscriber queries P2P network and finds a file to download from a P2P user on the Internet ISP subscriber makes a download request. Layer 7 redirector transparently redirects P2P traffic to UltraBand cache UltraBand serves ISP subscriber’s request directly if file is already stored in cache hence saving bandwidth on the internet transit link UltraBand maintains the connection with the Internet user to maintain transparency
