Abstract: Identifying a component within an application executed in a network includes obtaining a traffic matrix, the traffic matrix defining a rate for which packets of data are exchanged between VMs corresponding to an application, analyzing the traffic matrix to identify VMs within a component, modifying the traffic matrix to create a modified traffic matrix, and defining, for the application, a tenant application graph (TAG) model based on the modified traffic matrix.

Abstract: In some examples, a system can verify a network function by inquiring a model using a query language is described. In some examples, the system can include at least a memory and a processor coupled to the memory. The processor can execute instructions stored in the memory to transmit a plurality of packets into at least one network function that is unverifiable; describe the at least one network function using a model comprising a set of match action rules and a state machine; inquire the model using a query language comprising a temporal logic to obtain a query result indicating an expected behavior of the plurality of packets; and verify the at least one network function based on the query result and the expected behavior of the plurality of packets.

Abstract: Example implementations disclosed herein can be used to allocate network resources in a software defined network (SDN). In one example implementation, a method can include receiving a plurality of resource allocation proposals from a plurality of controller modules, instructing the controller modules to generate votes for the plurality of resource allocation proposals, and selecting one of the plurality of resource allocation proposals based on the votes to instantiate the selected resource allocation proposal in the SDN.

Abstract: Example method includes: receiving, by a network device in a network, a first network policy and a second network policy configured by a network administrator, wherein the first network policy comprises a first metric and the second network policy comprises a second and different metric; detecting, by the network device, a conflict between the first network policy and the second network policy; determining, by the network device, a relationship between the first metric and the second metric; modifying, by the network device, at least one of the first network policy and the second network policy to resolve the conflict based on the relationship between the first metric and the second metric; and combining, by the network device, the first network policy and the second network policy to generate a composite network policy that is represented on a single policy graph.
