8.2.8 VP-Ring/VC-Ring Protection
VP-Ring/VC-Ring protection switching on the ATM layer is similar to path protection
for SDH in principle and features, as shown in Figure 8-8. VP-Ring/VC-Ring protection
reserves protection resources to achieve protection. It can be used on any physical
topology. The reserved protection resources include routes and bandwidth.
