FIG. 5 is a sequence diagram illustrating an example dynamic high availability process in accordance with techniques described herein. FIG. 5 illustrates a use case describing dynamic high availability (DHA) when any vBNG instance is deemed unalive based on heartbeat and health. NRM 441, NICM 445, NLB 447, and NSDB 443 may create a new vBNG instance and recover all the subscriber and service information corresponding to the faulty vBNG. NRM 441 may instruct instance manager further to clean up the faulty vBNG. FIG. 5 is discussed with respect to FIG. 1 and FIG. 2 for exemplary purposes only. vBNG 1 457 may be an example of vBNG A 57N of FIG. 2. NRM 441 may be an example of NRM 41 of FIG. 2. vBNG N 461A may be an example of vBNG A 61N of FIG. 2. NICM 445 may be an example of NICM 45 of FIG. 2. vBNG N 461N may be an example of vBNG N 61N of FIG. 2. NSDB 443 may be an example of NSDB 43 of FIG. 2. NLB 447 may be an example of NLB 47 of FIG. 2.
