Real-time bandwidth encapsulation for IP/MPLS Protection Switching [PDF]

, 2011
Bandwidth reservation and bandwidth allocation are needed to guarantee the protection of voice traffic during network failure. Since voice calls have a time constraint of 50 ms within which the traffic must be recovered, a real-time bandwidth management ...
