VNS is a high-capacity 3GPP PCEF compliant system in respect to service flow detection, user plane traffic handling, triggering control plane session management, QoS handling and service data flow management. In addition to mandatory features it provides a host of features such as in-line captive portal re-direction, subscriber traffic rerouting, dialogue injection, precise time metering (as opposed to connection based – which includes paused durations) and application sensitive volume metering (for example accurately identifying true facebook.com traffic from mashup applications) to truly enable operators to address innovative and profitable service differentiation.

Business Capabilities : Micro-meter fair-usage policies and segment services by parameters such as volume, time, application, traffic source and events. Implement application and service sensitive interactions such as video clip pause, domain access (e.g. Google group, operator portals or all video protocols) and first use triggers. Assure revenue by authorising, reserving balances or checking credit limits before session starts or event is delivered and committing upon thresholds or successful event delivery. Eliminate bill-shock and settlement loses. Ensure transparency, control and personalisation by interacting with subscribers in real-time by redirecting sessions to service dialogues that advice in real-time on usage, top-ups and other options. Not only collect new revenue but improve customer experience across pre-pay, post-pay and on-demand users. Deliver on SLA by enforcing service policies dynamically on an individual subscriber/service basis by gating, buffering, filtering, allocating bandwidth and prioritising traffic to specific applications or services. Enable new revenue collection from on-demand service personalisation. Improve or degrade experience on specific services, partner domains and applications by shaping the traffic appropriately – to maximise revenue from new services or protect traditional revenue streams. Move up the value chain by charging not only on cost-plus access basis but also on advanced data service basis such as VoIP, Messaging, VPN Access, Video on Demand and IPTV. Maximise investments and minimise upgrade costs of service delivery platforms, by providing richer subscriber information through header enrichment, packet marking and traffic routing on a subscriber or service level. Minimise service latency and capacity upgrades, by smartly routing traffic in a non-serial fashion. Understand what your subscribers are actually using with the help of traffic and service reporting.

Functional Capabilities : Layer 3, 4 and 7 based classification, bi-directional Shallow (Layer 3 /4) and Layer 7 Deep Packet Inspection (DPI) with traffic identification based on heuristic and 7-tuple analysis Protocol detection of over 1000 protocols and applications Regular protocol database update User defined protocols to track or shape traffic to and from specific applications Encrypted protocol detection Shaping (Prioritisation) Real-time policy enforcement Real-time charging Tethering detection IPv6 support 3GPP PCEF/TDF compliant Radius, Diameter, Gx and proprietary interface support Multiple APN support Multi Gigabyte support GUI based usage reporting for charging, policy management, billing and regular traffic monitoring In-built load-balancing and routing capability Redundant components and high availability system ToS and Header Enrichment

The Policy and Charing Enforcement functionality within VNS can be deployed in a modular format, to suit existing eco-system investments. Volubill Network System suite contains two products: 

• VNS Core Controller - an enhanced 3GPP PCEF product
• VNS Service Controller – service control and dialogue management product
