Marratech's first product, which offered voice, video, whiteboard and group instant messaging, was first released in November 1998. The first release required the presence of an IP multicast network and was built as a server-less architecture. The solution has since evolved to support both traditional IP Unicast and IP multicast, high security and multi-platform computing. For guaranteed, serverless, scalable data delivery over both Multicast and Unicast, Scalable Reliable Multicast (SRM) is used over the Real-time Transport Protocol, called SRRTP.
