What Does Service Advertising Protocol (SAP) Mean?
Service Advertising Protocol (SAP) is an automated internetwork packet exchange (IPX) protocol component for adding and removing services. It is mostly implemented by system administrators and application developers.
SAP is a distance vector protocol that allows network services, such as file/print/gateway servers, to dynamically register data in server information tables. IPX services are then periodically broadcast across a network and its subnetworks.
