Qosmos Service Aware Module: L7 Classifier for Virtual Switch

The Qosmos Service Aware Module® (Qosmos SAM®) is a Classifier concept adding Layer 7 visibility to virtual switches. Suppliers of equipment, platforms, middleware, and software can leverage this building block to rapidly build application-aware solutions for service providers, data centers and enterprises.

The virtual switch (or vSwitch) plays a critical role in next generation data center networks. It is a software application that allows virtual machines (VMs) to communicate with each other and with the physical network.

Qosmos SAM® is integrated with a vSwitch to provide detailed, real-time traffic intelligence and enable service-awareness at the infrastructure level. The new module classifies flows at the hypervisor level and the resulting protocol information and metadata are either used directly by the virtual switch or passed on to guest applications for e.g. east-west security between VMs or traffic visibility up to Layer 7.

Qosmos SAM conveys real-time intelligence up to Layer 7 via an open API designed to enable short development cycles. Qosmos is working with leading switch vendors and the open source community to drive innovation while ensuring API compatibility and improving performance.

Qosmos SAM is based on Qosmos’ flagship product ixEngine®, which is already established as the de facto industry-standard classification and metadata engine for developers of telecoms and enterprise solutions. ixEngine identifies and extracts information traveling over networks in real time, providing a true picture of the traffic by identifying protocols, types of application, and extracting additional information in the form of metadata. Equipment makers, telco and enterprise software vendors, and cloud service providers use Qosmos to gain application awareness, accelerate time to market and benefit from continuous signature updates.
