Techopedia Explains Sequenced Packet Protocol

SPP is similar to Transmission Control Protocol (TCP). A key technical difference is that SPP packets count sequence numbers but not bytes.

SPP manages several functions. It uses destination identification (ID) numbers for transport link target end definition. It also uses sequence numbers for transmitted and sequenced packet maintenance. SPP acknowledges allocated numbers for previous packets, which ensure destination reception alongside indicating successful transmission completion.

Novell’s Internetwork Packet Exchange/Sequenced Packet Exchange (IPX/SPX) is directly derived from SPP.
