SMART Multicast - SMART Multicast Uses

SMART Multicast Uses

IP Multicast has been successfully deployed in private and controlled networking environments, for example; IP over fiber - cable TV operators, educational institutions with significant on-campus student housing and financial sector applications such as stock tickers and hoot-n-holler systems. However, IP multicast has been slow to be adopted in the interdomain routing environment. This is because the current interdomain infrastructure lacks the necessary tools to efficiently handle packet loss and the security needed to create a functional business model.

SMART IP Multicast is an experimental protocol that enables the interdomain transmission of Secure Reliable IP Multicast, thus overcoming the challenges of deploying wide area interdomain IP Multicast transmissions. SMART IP Multicast reduces the complexity of deploying wide area IP Multicast in the same way MFTP (Multicast File Transfer Protocol) accomplishes this goal for file transfer, namely allowing for security and reliability to have full interoperability.

IP Multicast file distribution has been the most successful use of IP Multicast within campus and commercial networks. For file distribution most have used some variant of the experimental protocol MFTP (Multicast File Transfer Protocol). MFTP is both secure and reliable and runs on top of IP Multicast protocol. Like MFTP, SMART Multicast is a wrapper that runs on top of IP Multicast, taking advantage of IP Multicast's efficiency. SMART Multicasts are secure, reliable and provide for bi-directional feedback.
