The concept of a domain is fundamentally relevant to segment routing (SR) Flexible Algorithm (Flex-Algo) technology and to Border Gateway Protocol (BGP) backbone networks. Additionally, all Internet service providers (ISPs) employ the concept of a domain to distinguish network segments for manageability and traffic control. The existing metrics are, however, confined to nodes and links. To address this limitation, techniques are presented herein that support a number of new metrics which apply to a domain and which help an operator to improve predictive networking, network correlation, and traffic engineering at a domain level. Such metrics provide a measure of, among other things, stability, bandwidth or resource utilization, security, homogeneity, age, traffic resiliency, diversity, cost per bit, etc.
