Boxborough, Massachusetts-based Agile Networks Inc claims that it has the first virtual local network technology that automatically supports IP Internet Protocol multicast over switched local networks. The function has been incorporated into the virtual local network software which ships with its ATMizer family of local network switches. IETF’s Multicast aims to maximise use of network capacity by enabling a single station on the network to send one IP packet to multiple destinations. It uses IP Class D addresses to identify the desired end-stations and sends data only to those and uses Internet Group Management Protocol to enable end-stations to join and leave multicast groups.
