Patent number: 11455184Abstract: Concepts and technologies are disclosed herein for end-to-end validation of virtual machines. A control system including a processor can detect a validation request that can include a request to create an end-to-end validation function to perform end-to-end validation of a service. The processor can analyze a policy to determine components of the end-to-end validation function and a virtual machine that will host the end-to-end validation function. The components can include a generator function and a receiver function that can encompass the service. The processor can load, or trigger loading of, an image to the virtual machine and instantiation of the virtual machine. The image can include the end-to-end validation function. The processor also can validate the service using the end-to-end validation function based upon a test scenario stored in a test library of the end-to-end validation function.Type: GrantFiled: July 12, 2021Date of Patent: September 27, 2022Assignee: AT&T Intellectual Property I, L.P.Inventors: W. Cooper Chastain, Larry B. Pearson, Cameron Scott Blandford

Patent number: 10505901Abstract: Concepts and technologies are disclosed herein for providing a basic firewall using a virtual networking function. A control system having a processor can detect a firewall request that can include a request to create a basic firewall. The processor can analyze a recipe to determine a virtual switch and a basic firewall virtual function that are to provide the functionality of the basic firewall. The processor can trigger instantiation of the virtual switch via a network control function and instantiation of the basic firewall virtual function via a service control function. The processor also can validate the basic firewall. The basic firewall can provide filtering of traffic at the network transport layer using the virtual switch, and as such, the virtual switch may not operate on the application layer.Type: GrantFiled: December 7, 2018Date of Patent: December 10, 2019Assignee: AT&T Intellectual Property I, L.P.Inventor: W.

Patent number: 7907539Abstract: Systems and methods are provided wherein call-blocking probability of a telecommunications system is calculated based on consideration of over flow paths and alternate routes. Once the routes and overflow pathways are identified, the total number of call attempts and calls failed, due to congestion, is determined from statistical route data. Dividing the number of failed calls due to congestion by the number of attempted calls results in the blocking proportion for each route that is used by the methods disclosed herein to calculate the probability of blocking for that route.Type: GrantFiled: November 7, 2007Date of Patent: March 15, 2011Assignee: AT&T Mobility II LLCInventor: W.
