HSC offers the following Accelerators today:
The Pub-Sub Framework and SDK is used to share live data among independent network entities or service endpoints in near-Realtime. This accelerator is well-suited for sharing internal state, counters and similar monitoring points among virtual network functions running in context of VMs or containers. Using an optional SDN controlled, OVS or OVS-DPDK based virtual data bus, this solution promises real-time data sharing in a distributed deployment. Inter-VM Data is shared over OVS bridge or DPDK compliant OVS bridge using the OVS-DPDK provided para-virtualized virtio PMD.
The SDK provides a publish-subscribe mechanism to distributed applications or network functions, using which they can expose their internal states or variables to peering entities. This information can then be used for any kind of monitoring or decision making.
The SDK is based on a library offering APIs for the following:
The SDK provides easy integration of these APIs with any proprietary application code base under test. The “publish” APIs can be used to publish the internal states or variables of an application. The user can also associate context information with the published info. The consumer of the information can be another application which can call “subscribe” APIs. The “subscriber” application can subscribe for a particular state or variable – retrieving information from all instances of the publishing application. It can subscribe for all states/variables published from a specific instance or all instances of the publishing application.
The SDK can handle diverse underlying networking mechanism. But it can give tangible benefits in a virtualized environment. Using OpenStack as VIM and VMs/containers to deploy the network functions or s/w components, the SDK provides a robust infrastructure to share data/states among the VMs/containers.
The SDK APIs are integrated in the application code and packaged along with the applications. Thus, the publishing and subscribing of data is triggered automatically from the functional flow of the applications from the VMs/containers running them.
The diagram below shows one deployment scenario where the SDK has been used to share data among applications running in context of OpenStack VIM based network.
Though the SDK itself is modular enough to run over any networking infrastructure, but to attain real-time data sharing in a virtualized environment (as depicted in the figure above), following requirements exist:
The aforesaid accelerator solution can be applied in the following use-cases:
