Systems and methods for establishing routing information between software containers or other virtualized environments within a network, and providing inter-container routing between the software services operating on the network, are disclosed herein. The system utilizes an existing routing protocol such as Open Shortest Path First (OSPF) and establishes an overlay network that provides end-to-end connectivity between services of a customer operating in an Infrastructure as a Service (IaaS) network, while maintaining isolation from the traffic of other customers of the IaaS network. The system uses OSPF to learn aspects of the routes between containers in the network, and further builds a customer-specific overlay network based on IP-to-IP encapsulation of the OSPF messages.

Container routing algorithm using OSPF

The disclosed method tests performance of a wireless telecommunication network. The method obtains from the network a network trace including packets exchanged among devices associated with the network. The method identifies packets within the network trace that match properties specified by the first and second tables, and obtains a call flow by chronologically mapping the identified packets, using the timestamps of the packets. The method determines whether a packet associated with the call flow matches the properties specified by the third table by comparing an IE value contained in the packet to the IE value included in the third table. Based on the determining, the method creates a call flow validation results report indicating whether the call flow satisfied the properties specified in the multiple tables. The call flow validation results report can indicate whether the network has passed the test, and/or whether the wireless network has any problematic components.
