Traffic Steering Engine
Price On RequestThe Traffic Steering Engine (TSE) delivers carrier-grade horizontal scale and reliability in a completely virtualized solution, so it s aligned with communications service providers network functions virtualization (NFV) strategies; plus, the TSE is subscriber-aware, so it s the perfect enabler of today s subscriber-centric network services. Service Function Support The TSE supports steering traffic to service functions provided by Sandvine (e.g., TCP acceleration, policy control, etc.) or any third-party service function that s compliant with the IETF Service Function Chaining (SFC) standard. Asymmetry Support Unlike data center networks, communications service provider (CSP) networks have routing asymmetry. The TSE can be deployed in networks with any degree of asymmetry, while still guaranteeing service function instance affinity. Horizontal Scalability The TSE delivers the cost-effective horizontal scalability that CSP networks need, but is lacking in alternatives re-purposed from other markets/applications. Subscriber Awareness The TSE s subscriber awareness ensures the traffic from only the appropriate subscribers is sent through the appropriate service function chain, ensuring an efficient, high-performance deployment. Deploying the Traffic Steering Engine The TSE is deployed in the network s data plane, where it intersects the network s traffic.In practice, the TSE s tunnel/encapsulation support means that it can be installed almost anywhere in the network, which unlocks a number of very interesting deployment scenarios. For instance, an operator could install TSE deployments throughout the network, near the subscriber edge, and configure each deployment to collectively (and selectively) steer traffic to a central deployment of the Sandvine Policy Traffic Switch (PTS) Virtual Series (i.e., for policy control use cases to be applied).
