Crossing the Gi: Will Edge Caching Be the Key to Managing Mobile Traffic?

Mobile data traffic is growing exponentially, driven by penetration of smartphones and adoption of mobile broadband. This trend is being facilitated by growing volumes of content, particularly rich media content such as video, becoming available via video sharing sites and social networks. In addition, operators are themselves launching multimedia services, in many cases extending pay TV services to mobile and other devices.

Usage of dynamic, multimedia applications is particularly significant. These applications take up a disproportionate amount of capacity on the network and can create congestion. Video is perhaps the most significant of these applications, and will account for the majority of mobile traffic this year. What's more, it is expected to keep growing.

This growth in traffic is starting to strain mobile networks, and affect operating expenses. Operators are finding that congested networks result in latency and lower quality of experience (QoE) for end users. This can aggravate consumers and drive churn something operators cannot allow in competitive markets.

In a survey of 50 mobile operators around the world conducted by Heavy Reading, 86 percent agreed this would be a serious challenge in the coming years and more than half strongly agreed, as shown in the excerpt below. This suggests a clear recognition within these organizations that the problem was severe and needed urgent resolution.

Mobile operators are looking for solutions to manage network traffic in a cost-effective way while still preserving a high end-user QoE. Fixed-line operators, already feeling the pressure of video traffic growth on their networks, have been deploying transparent caches at the edge of their networks in recent years. Mobile operators with even scarcer network capacity are also now hoping to leverage this technology. But mobile networks are a different environment from fixed, and create a new set of challenges for video caching and delivery. Can caching work in the mobile network?

Crossing the Gi: Will Edge Caching Be the Key to Managing Mobile Traffic? explores the growth in mobile traffic, its primary drivers and the current status of caching on mobile networks. The report reviews the unique challenges of caching on mobile networks and evaluates the primary drivers and challenges for operators using caching as a solution.


The report also includes specific analysis of 16 key vendors in this space, describing their solutions and strategic positioning in this market, as well as their relative strengths and weaknesses.

In a sense, the mobile caching space is not a separate market as much as it is an extension of other, adjacent markets. Caching is unlikely to be deployed on a mobile network in isolation; we anticipate most solutions will be integrated, partnered or part of larger traffic management solutions. Mobile optimization, network infrastructure, policy and RAN intelligence-type capabilities will all be leveraged alongside caching to better manage network traffic. This is evidenced by the types of vendors that are targeting this market.

Broadly speaking, mobile caching vendors can be categorized into four groups, based on their history and the types of solutions they offer. Individual vendors within the same grouping have similar objectives, strategies and opinions. Unsurprisingly, they also demonstrate many similar strengths and weaknesses, though they do have individual attributes.
