What are the advantages in using optical rings based on PurePacket technology?
One of the significant advantages of the Integral Access packet optical ring is the ability to protect traffic on a services and customer basis, rather than on a physical or logical facility basis which is the case with SONET/SDH and other traditional technologies. Customers that pay for full protection can have their traffic protected using dual paths, while unprotected traffic can use the balance of the dual path connection bandwidth. In the event of a path failure, the protection traffic is guaranteed to continue on a hitless basis, with other traffic transported on the remaining bandwidth based on traffic priority levels.
