For example, UNSM 53 may receive network security data from vBNG instances 57 and 58. In this example, UNSM 53 may analyze received network security data to generate one or more alerts. As used herein, one or more alerts that may be generated by UNSM 53 may refer to informing a human administrator and/or operator. For example, an alert may include, a syslog, pop-up, or another alert. In this example, UNSM 53 may configure vBNG instances 57 and 58 based on the network security data. For instance, UNSM 53 may exchange (e.g., receive and/or output) security related information with each vBNG instance of vBNG instances 57 and 58 as discussed above. In some examples, UNSM 53 may output, to each vBNG instance of vBNG instances 57 and 58, updates. In this example, each vBNG instance of vBNG instances 57 and 58 may receive updates from UNSM 53 of BNG controller 35.
In accordance with one or more techniques described herein, NSDB 43 stores vBNG instance information for one or more subscriber devices. The vBNG instance information may specify vBNG instances 57 and vBNG instances 58A-58M. NICM 45 modifies the vBNG instance information to include an additional vBNG instance to be added to vBNG instances 57 and 58. For example, NICM 45 may add vBNG instance 58N to vBNG instances 57 and vBNG instances 58A-58M. NICM 45 outputs an instruction to generate vBNG instance 58N at edge router 30N.
