Publication number: 20220311671Abstract: A processing system may obtain an intent comprising a desired network state for a telecommunication network, determine an existing network state, where the desired network state and the existing network state are defined in accordance with a graph representing the telecommunication network, where the graph includes objects and relationships between the plurality of objects, and where each of the objects includes one or more properties. The processing system may compose a strategy that includes a plurality of policies to obtain the desired network state from the existing network state, where each of the policies comprises an action that is to be implemented in the telecommunication network, where the composing comprises performing a state exploration process over the graph, and where each state transition of the process corresponds to one of the policies.

Publication number: 20220263771Abstract: Performance issues in a service function chain having a plurality of resources and a plurality of network functions each having a network function queue are diagnosed. Each network function queue is monitored and queueing information for input packets for each of the plurality of network functions is dumped to a data store. Each resource that is under contention is identified as well as which of the network functions is a contender for the resources. A diagnosing algorithm is used to diagnose performance problems and an impact graph for each victim packet is generated. A summary of results as a list of rules is then provided.Type: ApplicationFiled: May 3, 2022Publication date: August 18, 2022Applicants: AT&T Intellectual Property I, L.P., President and Fellows of Harvard CollegeInventors: Muhammad Bilal Anwer, Aman Shaikh, Junzhi Gong, Minlan Yu, Yuliang Li
