Subnetwork Access Protocol
An
Internet protocol that operates between a network entity in the subnetwork and
a network entity in the end system. SNAP specifies a standard method of IP
datagram and Address Resolution Protocol (ARP) message encapsulation on IEEE
networks. The SNAP entity in the end system makes use of the services of the
subnetwork and performs three key functions: data transfer, connection
management, and QoS selection.
