Restorable VPN Transmission System for Images Broadcasting System

The previous work, suggests a portioned picturebroadcasting system where screens of small size are accumulated togenerate screen of bigger size through Ethernet network interfacethat helps in easy install & implementation of digitized displaydevices. The system makes use of Texas Instruments Da Vinciplatform, that is comprised of Da Vinci TMS320DM6646 dual coreCPU along an ARM9 core & C64+ digitized signal processor as abasic preprocessor & accelerated processor to enhance the speed ofpartitioning the picture & transmission in the several devices fordisplay. A protocol having low value for overhead is taken intoaccount for synchronizing each frame in distributed multimediasystem in the connection. For dealing such issues of delay in nettransmission & loss of packets, a standard precision time protocolIEEE 1588 is applied & transformed to attain seamless partitionedsystem of broadcasting. In this paper, an algorithm is suggestedthat search for backup path for a provided VPN (VPN tree) thatfalls under single link failure model. As any failure of link in a VPNtree is recognized, a backup path associated to the failing link istriggered for restoring the de-linked VPN tree to another one &further ensure reliability of a provided VPN. The proposedalgorithm has the ability for minimizing the delay in transmission & loss of packets.
