Smart Service Gateway Video Optimization Media Server


1. Description
   The wide take-up of the latest generation of smart devices together with the exponential increase in the number of application that provide a wireless multimedia service means there is a growing need for a device that can classify, optimize and thus offload traffic caused by such devices and applications.

Plus, there are more R&D projects being promoted to target improvements to networks that help VAN (Value Added Network) devices become easily adopted as a way to boost user QoE and the CAPEX of the operator.

SSG (Smart Service Gateway) is a carrier-level DPI/DFI solution providing features to detect/control/classify traffic from services and applications created/removed/changed frequently. This is to facilitate the adoption of the x-aware service and, at the same time, support the simple and flexible operation of the mobile core network. In addition, the solution interworks with SDN networks to implement a Smart Network that is capable of service chaining.

2. Key Features

Policy-based traffic control by subscriber, by category and by application (Pass/Drop, Rate Control,
   Route, Mirror, Limit, Divert available)
Destination IP-based traffic bypassing
Policy management: manages traffic by subscriber, by rate system and by service
Statistics: complies statistics of traffic by application, by user and by mVoIP
