ABSTRACT
Telecommunication networks have historically relied heavily on the administration of user features and their access to the network. Data networks completely negated this approach and made a wide variety of services available to users, including selfadministration of features and access. As has become evident over the last few years, complete self-administration of user features, user access, and administrative rights without authentication and without any accountability is not working properly anymore. Spam, fake sender identification, and intrusion into networks and data centers have been made possible by a variety of factors, including the lack of at least a basic level of Operation, Administration, Maintenance, and Provisioning (OAM&P) for network access rights. Additionally, traffic engineering in data networks has largely been unsuccessful due to a lack of insight into the networks’ load status and the nodes’ statuses. As a result, in future advanced networks-Internet2 and other, smarter integrated networks-OAM&P will be of paramount importance in advanced router designs. It is a crucial hardware, firmware, and software building block in current and future networks and all nodes thereof.
