===SDT (Session Data Transport)===

SDT is a [[reliable multicast]] transport protocol which operates over [[User Datagram Protocol|UDP/IP]] which can be used to group peers within a network into ''sessions'' and deliver messages to them individually or as a group. Messages delivery is ordered and messages may be selectively sent [[Reliability (computer networking)|reliably or unreliably]] on a message-by-message basis (reliability is very important for some data while avoiding the time and resource overhead of the reliability mechanism is beneficial for others). The reliability mechanism also provides online status so a component will detect when a connection is broken. SDT provides a high degree of fine tuning over the trade-off between latency, reiabilityreliability levels and resource requirements and availability of large numbers of concurrent sessions means they are a powerful tool for grouping and managing components whose functions are related or whose communication requirements are similar.
