UR SWITCH MODULE – QUICKSTART GUIDE QS–3
QS.1.2 Supported Network Topologies
With both media, supported topologies include Star, Mesh, and Ring. The port that
connects one switch to another is often called the uplink port and with many switches the
uplink port can operate at much higher baud rates than the standard ports. The link
formed by the connection of several switches’ higher speed uplink ports is often referred to
as a backbone.
Star Architecture
• Single point of failure before loss of communications
• Additional Ethernet Switches Required
Mesh Architecture
• Multiple points of failure required before loss of communications
• Additional Fiber Cables required
Ring Architecture
• Full Network Redundancy
• Allows for Fastest Network Recovery
*
• Most Cost Effective Solution
* RO mode has typical recovery time of ≤ 5 ms/hop.
