Service Chain Management

摘要

In telecommunications service chains are typically implemented as a chain of services implemented in a virtual environment. The service chain may be changed without causing unnecessary long delay to the operation of the chain by configuring the application implementing the service in the chain and then changing the output identifier of the previous application to correspond with the input identifier of the added application. The data traffic flow starts almost immediately to flow according to the new ser vice chain and there will be no long delays caused by restarting the services but only a minimized delay.
