Policy enforcement based on L7 intelligence
Telco infrastructure based on the principles of software-defined networking (SDN) and network functions virtualization (NFV) will give operators increased flexibility in how and where network functions are deployed. One example is deep packet inspection (DPI), which can be integrated in a virtual switch to enable high-performance and cost-effective traffic shaping.
Network operators require the ability to implement and enforce service-level agreements (SLAs) with priority given to time-sensitive traffic, like voice and video, or subscribers of preferred service plans.
Qosmos DPI technology and traffic shaping functions can be added to a virtual switch, allowing a policy and charging rules function (PCRF) to set policy based on a flow’s application ID and metadata data (e.g., jitter). The hypervisor-hosted solution runs on an Intel® Xeon® processor-based platform and bypasses Linux kernel performance bottlenecks via the Intel® Data Plane Development Kit (Intel® DPDK), which accelerates I/O for the guest virtual applications and virtual switch communication. The policy enforcement OEM application is pre-integrated into the standard hypervisor and provides external interfaces to the policy and rules function.
