TokenSpeed Module Applications

This chapter provides information about typical uses of the TokenSpeed module to improve network performance. The chapter includes information about the following uses:

•Giving a server a dedicated port (see this page)

•Segmenting a ring (see page 2-2)

•Replacing a source route bridge or router (see page 2-5)

•Concentrating rings into a router (see page 2-5)

Giving a Server a Dedicated Port

You can improve server response and increase throughput capacity by giving a server a dedicated port on the TokenSpeed module.

Note: Giving a server a dedicated port on the TokenSpeed module need not increase the source route hop count. You can maintain or even decrease the source route hop count by assigning the server to the same virtual ring as its communicating stations (refer to Using SpeedView 2.1 for Windows.)
