SMS: Remote Control Uses TCP Instead of UDP

• Microsoft Systems Management Server version 2.0

SUMMARY

Systems Management Server 1.2 uses User Datagram Protocol (UDP) for socket-based Remote Control sessions. UDP is a datagram-based protocol. It is an unreliable, or best-effort protocol that does not verify that packets are not received out of order, lost, or corrupted. Consequently, UDP-based Remote Control was prone to connectivity problems.

With Systems Management Server 2.0, socket-based Remote Control now uses Transmission Control Protocol (TCP). TCP is a stream-oriented protocol. TCP breaks the transmission into smaller sizes, retransmits lost packets, reorders out of order packets, and filters any extra packets that might occur if the transmission is faulty. Consequently, TCP is more reliable than UDP.

Remote Control performance across a wide area network (WAN) is improved in Systems Management Server 2.0 over 1.x when using sockets-based Remote Control because routers tend to give TCP packets a higher priority for transmission.
