SNA Links Overview
SNA/Token Ring Link Overview
SNA/Token Ring Link Overview
SNA/Token Ring Link is composed of hardware and software:
• Token Ring HP-Precision Bus (HP-PB) adapter card (hardware)
• SNA Transport (software)
• Token ring link module (software)
• Token ring link driver (software)
The SNA/Token Ring Link uses the HP Token Ring HP-PB adapter
card to connect to the token ring LAN. The SNA/Token Ring Link
implements an IEEE 802.2 type II driver to handle connection-oriented
traffic and IEEE 802.5 Token-Passing Ring Medium Access Control
(MAC) deterministic access method.
As a token ring allows an any-to-any connection, users on an HP 3000
can run different applications on different remote systems. Figure 1-5
shows how SNA/Token Ring Link and the SNA services implement
HP 3000-to-IBM host or HP 3000-to-AS/400 communication.
