SNA PU type 2.1 allows local user ports to communicate without going
thorough a host node's SSCP services.s
Reverse Address Resolution Protocol. A TCP/IP protocol used for
downloading IP addresses in UNIX/Linux networks. It requires a RARP
daemon on your system, and only operates within a single network
segment. A request made to an active RARP daemon initiates a search of
the Ethernet Address Table for an entry matching the print server's
Ethernet address. If a matching entry is found, the daemon downloads the
IP address to the print server.
Reduced Instruction Set Computing. A processor that recognizes only a
limited number of assembly-language instructions.
Service Advertising Protocol. A NetWare network name advertising
service that e.g. file servers can use for advertising their existence to
network clients.
Service Access Point. Field defined by the IEEE 802.2 specification that is
part of an address specification. Thus, the destination plus the DSAP
define the recipient of a packet. The same applies to the SSAP
SNA Character String. A sequence of control commands that allows
sophisticated control of printers and other devices.
Systems Network Architecture. IBM's data communications architecture
defining levels of protocols for communications between terminals and
applications as well as between programs. Originally SNA was strictly
host-based with VTAM controlling the network except for path control
which was provided by NCP in the FEP. Recently, with the APPN/APPC
and HPR additions SNA has become more distributed.
Simple Network Management Protocol. Standard management protocol
for network attached devices.
Sequenced Packet Exchange, a NetWare communications protocol used to
transmit messages reliably over a network.
System Services Control Point. SNA software within VTAM which
handles network name/address conversion, device configuration, network
diagnostics and recovery. The SSCP is a NAU located on a host node in
the network.
Secure Sockets Layer, a protocol designed to provide secure
communications on the Internet.
Transmission Control Protocol. The connection-oriented, transport-level
protocol used in the TCP/IP suite of protocols.
