3. Examples of Ring Protocol Systems

The Ring Protocol offers a simple configuration and high-speed redundant path switching, allowing you to

configure a path redundant system with the smallest possible number of required ports and lines. Therefore, The

Ring Protocol is very suitable for the needs of the core network.

This chapter provides some examples of practical system applications.

3.1 Single ring application for a building network

This section provides an example of a network system in a building that takes advantage of the Ring Protocol.

In a network in a building, the Ring Protocol is best suited to the inter-floor backbone network that connects core

switches and access or distribution switches.

(1) Basic configuration

The following figure shows the equipment configuration and general wiring when you apply the Ring Protocol

to a network in a building.

3.1-1 Basic configuration of a building network

This configuration uses a single ring to connect the backbone between core switches and distribution or access

switches on each floor.

Unlike a redundant configuration with STP, which often requires inconvenient wiring, this configuration

allows you to make wiring on each floor simple and easy. Also, the core switch uses only two ports, regardless of

the number of access or distribution switches on each floor. These advantages are highly cost effective.

However, in this configuration, the nodes on the top and bottom floors must be connected to form a ring, so

that some configurations might require long wiring. If UTP cables are used for wiring of the ring, the length of

cables must be considered.

is long.
