Stoke Tunes its Mobile Data Offload for CDNs

Stoke has tuned its mobile data offload solution to enable core-bound applications to be deployed with greater effectiveness at the edge of the Radio Access Network (RAN).

Through a set of enhancements to its flagship mobile broadband gateway, Stoke is providing the capability to selectively steer traffic at the edge of a mobile to a collocated Content Delivery Network (CDN). In laboratory trials combining the Stoke MDO with a collocated Content Distribution Network (CDN) edge server, mobile user website load time latencies have been reduced by 60%.

Stoke said this new edge deployment location, together with control plane information not available in the network core, is affording application providers new opportunities for innovation and is already leading to service delivery improvements. Essentially, Stoke's selective traffic breakout solution enables application providers to improve performance and QoS by locating critical traffic control, optimization, and content acceleration functions closer to subscribers.

Specifically Stoke's 3GPP standard selective breakout gateway intelligently intercepts and re-directs select data traffic. New enhancements in support of the Edge Service Exchange ecosystem include the following:

  • API accessible RAN routing area details for offloaded sessions (e.g. RAC/SAC)

  • API accessible session details (e.g. IMSI, APN, Device IMEI, etc.)

  • API accessible Radio Access Bearer (RAB) and QoS parameters for sessions

  • Network controlled, real-time offload policy updates

  • Programmatic session start and stop notification for Service Exchange applications

  • Enhancements to breakout controls that mitigate potential failures in Service Exchange partner applications.

"Existing mobile data infrastructures are strained to the limit, and surviving the next wave of data growth may well exhaust current infrastructure upgrades and traffic mitigation solutions, said Daniel McBride, Senior Director, Product and Solutions Marketing at Stoke. "Stoke MDO, together with Edge Service Exchange ecosystem companies, effectively modernizes today's mobile network infrastructure while also managing unpredictable data growth."

Stoke is currently assembling an "Edge Service Exchange" ecosystem. It has begun testing with a number of globally recognized application providers, including Volubill, a leading provider of real-time policy management and charging solutions, and major players in mobile traffic optimization, cloud-based web application and content acceleration, and video CDN technologies.
