Survivability in optical network with differential delay using dynamic buffer size

Providing the survivability in optical networks over wavelength-division multiplexing (WDM) is a critical concern. The design issue on WDM network is to minimize the buffer size and providing survivability based on differential delay and Multipath provisioning with the support of Virtual Concatenation (VC). In this paper, we propose the Shared Protection of the Largest Individual Traversed link (SPLIT) for survivable multipath and MFI (Multiframe Indicator) Buffer to reduce the buffer requirement at the receiver end of the VC with the help of minimized differential delay.
