- SPXsearch for term
Sequenced Packet ExchangeA NetWare DOS Requester module that enhances the IPX protocol by supervising data sent out across the network. SPX verifies and acknowledges successful packet delivery to any network destination by requesting a verification from the destination that the data was received. The SPX verification must include a value that matches the value calculated from the data before transmission. By comparing these values, SPX ensures not only that the data packet arrived at the destination, but that it arrived intact.
