There are several reasons why network operators need to guarantee flow-based quality of service (QoS), for instance:
Sandvine provides several means by which network operators can guarantee quality of service.
For standards-driven QoS, like VoLTE requires, the Sandvine universal policy controller provides the signaling (e.g., Gx, Rx) that ensures different network components know what quality guarantees to apply to each flow.
By linking this standards support with Sandvine’s traffic classification capabilities, network operators can offer QoS guarantees for practically any traffic.
Additionally, Sandvine’s inline components can ‘mark’ traffic (e.g., DSCP) so that other network elements can observe the mark and apply the appropriate QoS.
Sandvine’s PCRF will play a key role in ensuring our customers enjoy a superior experience when making VoLTE calls.
Network operators who implement QoS guarantees do so knowing that crucial services will deliver a predictable quality of experience, either as required by a standard or as demanded by the marketplace.
