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.

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.

Providing a basic firewall using a virtual networking function

A system that incorporates teachings of the present disclosure may include, for example, utilizing a first diameter agent function to route messages between network elements that provide policy control and charging for a communication session, utilizing the first agent function to maintain transaction and session state during the communication session, and utilizing the first agent function to selectively adjust routing and non-routing information for the messages. Other embodiments are disclosed.

System and apparatus for providing policy control and charging to support communications

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.
