Aspects of embodiments provide methods and network criticality managers for controlling data traffic in a network. The method may include: obtaining network topology information from a plurality of physical resources used to transfer data traffic in the network; determining priority levels for data traffic in the network; using the network topology information and the determined priority levels to calculate criticality values for physical resources from among the plurality of physical resources, wherein the criticality values for the physical resources indicate the relative importance of the physical resources in the network; and controlling the data traffic in the network based on the calculated criticality values.

Methods and apparatus for data traffic control in networks

A method () for managing the provision of a service between origin and destination endpoints over a communication network is disclosed. The communication network comprises at least two Autonomous Systems (ASs) and an Abstraction and Control of Traffic Engineered Networks Virtual Network (VN) between the origin and destination endpoints. The method comprises defining, at each of the origin and destination endpoints, a service segregation loopback interface corresponding to a subset of traffic belonging to the service (). The method further comprises binding the subset of traffic to the VN by exposing the service segregation loopback interface defined at the destination endpoint as routing next hop only to traffic belonging to the subset ().
