A reliable network function virtualization (rVNF) system includes a virtualized network function (VNF) application instance that includes a plurality of physical VNF instances. A load balancer provides an interface between a client and the VNF application instance. A load balancer interface facilitates delivery of packets related to a particular user context to the same physical VNF instance. A communication interface facilitates communication between the client and the VNF application instance. Application storage stores session data associated with the VNF application instance.

Reliable virtualized network function system for a cloud computing system

In various examples there is a telecommunications network access point of a telecommunications network in which the control plane is implemented using a data center comprising a plurality of interconnected computation nodes. The access point comprises a memory holding a log of encapsulated control messages the control messages being messages of a control protocol of the telecommunications network. The access point has a processor configured, for a control message to be sent by the access point to a node in the data center, to: generate a message identifier; encapsulate the control message in a packet of a communications protocol of the data center, add the message identifier to a header of the encapsulated control message; send the encapsulated control message to the node of the data center; and store a record of the encapsulated control message and node of the control plane in the log.

Techniques are described for operating a core cellular network stack on a cloud computing environment (e.g., a public cloud infrastructure). For example, virtualized packet gateways can be run on virtual machines of the cloud computing environment and standard load balancers can distribute network traffic of the cellular network among the virtualized packet gateways. The virtualized packet gateways can be setup with a local cache of an external key-value store containing bearers of the cellular network and process received data plane network packets using the local cache. Bearers can be updated within the cellular network using the external key-value store, and virtualized packet gateways can obtain and use updated bearer details.

Implementation of core cellular networking stack on cloud infrastructure

Methods, systems, and computer readable media for simulating realistic movement of user equipment in an LTE network are disclosed. According to one method, a logical topology of a long term evolution (LTE) access network is defined that includes defining connections between one or more eNodeBs (eNBs). A physical topology of the LTE access network is defined that includes defining locations of the eNBs and sectors, where the physical network topology is mapped to the logical network topology. One or more problem areas are defined within the physical network topology, where the one or more problem areas include locations where signal quality is degraded. One or more paths are defined through the physical network topology. A traffic profile for a user equipment (UE) device is defined. A plurality of messages is generated for simulating the movement of a UE device along a path through the physical network topology.

Methods, systems, and computer readable media for stress testing mobile network equipment using CPRI are disclosed. According to one method, a plurality of messages is generated for simulating a plurality of user equipment (UE) devices. The plurality of messages is transmitted over a common public radio interface (CPRI) link to a radio equipment controller (REC) in order to stress test the REC component.
