Ubiquisys and Saguna ride RAN caching trend
To integrate Saguna's content optimization system with Ubiquisys' small cells to bring apps close to the user
Published: 11 February, 2013
There is a growing trend to carry out functions like content caching as close to the user as possible, boosting specialist suppliers of RAN-based applications platforms such as Saguna Networks. The company has announced an alliance with small cells vendor Ubiquisys to provide an integrated content and apps acceleration offering.
UK-based Ubiquisys will incorporate Saguna's CODS (Content Optimization Delivery System) product in its Smart Cell platform. The latter combines a cellular/Wi-Fi hotspot with an x86-based computer to carry out processing close to the end user, rather than in the core network. Functions for the processor, co-developed with Intel, include content caching and optimization of apps delivery based on the user's location and other settings.
The solution created with Saguna supports transparent caching of frequently viewed media, and DNS caching, on the smart cell, which includes carrier capabilities such as lawful interception, real time charging and policy management. The system can deal with cloud content and aims to harness app processing resources at the edge of the network to improve user experience and the costs of delivering mobile content.
"Mobile content delivery is an ongoing challenge for service providers. Working with RAN optimization experts Saguna, we've shown that it's possible simultaneously to reduce network traffic and improve quality of experience," said Pete Keevill, VP of engineering at Ubiquisys. "This is yet another example of the power of moving application processing resources to the network edge, closer to mobile users."
CODS uses RAN caching to reduce the delivery cost of web content and applications over HSPA and LTE. Popular content is stored at the network edge using a string of interlinked caching software nodes which can live in various locations such as base stations and gateways.
Last year Saguna integrated CODS with the VideoExchange content delivery network from The Netherlands' Jet-Stream to increase intelligence at the network edge; and in November, backhaul firm ADVA Optical Networking took a 10% stake in the Israeli company. Saguna says it could get its caching functionality into backhaul switches or even base stations for less than $100, which in turn could help carriers achieve a holistic view of traffic across the RAN, core and backhaul elements of the network.
