Abstract

Version 1.1 of the Workstation Program gains a new connectivity to host via a Token Ring. This connectivity supports SNA protocol. The connection to the host is accomplished by means of Token Ring adapter, Token Ring network, and gateway controller, such as 3725. (Image Omitted)

Workstation Program Token Ring Host Data Monitor

Version 1.1 of the Workstation Program gains a new connectivity to host via a Token Ring. This connectivity supports SNA protocol. The connection to the host is accomplished by means of Token Ring adapter, Token Ring network, and gateway controller, such as 3725.

To take full advantage of the existing DFT-SNA capability, a small Token Ring Host connectivity module was developed. This module consists of three components. As shown in Fig. 1, it employs Fixed Length Queue (FLQ) as the means of passing control and associated data. These FLQs are created with names, and thus can be name-resolved externally.

Problem:

The problem is how to monitor both the outbound and inbound data flows for the purpose of protocol verifications and problem determinations. Solution:

The FLQs are system resources; once created, they are known to the system by IDs. Since these FLQs have names, their IDs can be obtained through name resolution by a program loaded in the PC window. A special interface was built into the module to allow insertion of other FLQs into the path of normal data flows. Upon loading, Monitor creates a FLQ and inserts itself between the IDLC and the PU & Path Control components, as shown in Fig. 2. Monitor is then able to examine and to display both the outbound and the inbound data flows. Figs. 3 and 4 show some examples of data displayed by Monitor.
