Systems Network Architecture

system services control point

source-route bridging. Method of bridging originated by IBM and popular in Token Ring networks. In an SRB network, the entire route to a destination is predetermined, in real time, prior to transmission of the data to its destination.

System Services Control Point. Focal point within an SNA network for managing network configuration, coordinating network operator and problem determination requests, and providing directory services and other session services for network end users.

Session used by SNA to allow an SSCP to manage the resources of a node through the PU. SSCPs can send requests to, and receive replies from, individual nodes in order to control the network configuration.

Switch-to-Switch Protocol. Protocol specified in the DLSw standard, used by routers establish DLSw connections, locate resources, forward data, and handle flow control and error recovery. See also DLSw.

An explicitly configured route entered into the routing table. Static routes take precedence over routes chosen by dynamic routing protocols.

T

target

Any IP-addressable device or IBM Multiple Virtual Storage (MVS) mainframe that can be reached

 

by the source router. The target is the destination of the network performance measurement.

TCP

Transmission Control Protocol. Connection-oriented transport layer protocol that provides reliable

 

full-duplex data transmission. TCP is part of the TCP/IP protocol stack. See also TCP/IP.

TCP/IP

Transmission Control Protocol/Internet Protocol. Common name for the suite of protocols developed

 

by the U.S. DoD in the 1970s to support the construction of worldwide internetworks. TCP and IP

 

are the two best-known protocols in the suite. See also IP and TCP.

throughput

timeout

Rate of information arriving at, and possibly passing through, a particular point in a network system.

Event that occurs when one network device expects to hear from another network device within a specified period of time, but does not. Typically, a timeout results in a retransmission of information, or the cancellation of the session between the two devices.
