Solutions for Mobile Operators

Video is already consuming the majority of your wireless network and it’s just the start.
Is your network ready?

Qwilt's Video Fabric Controller Combines Open Caching, Video Delivery, and Analytics

Problem – Effective transmission rate of online video over TCP in wireless networks and overall network throughput is reduced severely due to latency, packet loss and buffer bloat conditions.

Solution – Open caching, coupled with TCP optimization increases the effective throughput rates and overall network utilization by up to 35%

Your Subscribers Love Online Video

Online video has changed from short-form progressive download to long-form with Adaptive Bit Rate and DRM protected content. Live streaming of sporting events will be the next tidal wave to hit mobile networks.

More than half of viewers’ time in mobile was spent watching videos that were longer than 30 minutes. Your network could use a boost.

Common Mobile Network Problems

Without Open Caching

Mobile Networks Without Open Caching Experience Congestion and QoE Issues

High End to End Network Latency

Inherent latency inside the mobile network can reach 10ms, while additional internet latency can at times be up to 50ms. The combined effect on the TCP connection over which video is transmitted is profound and can severely impact consumer experience and effective network throughput.

Packet Loss and “Buffer Bloat”

Wireless TCP heavily suffers from timeouts, the result of multiple losses in one window. Some radio networks have unnecessarily long and variable TCP RTT even when ping times are short – these delays are caused by data building up in the buffer queues in the RAN. The result is severe performance degradation.

Costly and Congested Mobile Backhaul

LTE improved the bandwidth of wireless air interfaces – however, the traditional mobile backhaul network has become a key bottleneck for LTE deployments. It restricts the upstream and downstream traffic flow and compromises user experience as LTE bandwidth is an order of magnitude greater than 3G networks.

Poor Video Quality of Experience

Long latency from content sites and RAN congestion during peak consumption periods result in slower downloads, delays in response, lower bit rates, and subpar experiences for consumers. In a highly competitive industry, consumer QoE is key to subscriber retention.

Operator Networks with Open Video Caching Provide Higher Level of Network Service and Quality of Experience for their Subscribers

Optimized video delivery

By delivering video from within the mobile network, at the Gi-LAN or inside the eNodeB, overall latency is reduced, video throughput is increased which enables delivery of higher resolution streams to today’s phablets and large screens.

Superior Network Utilization

Best-in-class caching and mobile-oriented TCP acceleration combine to shorten the video delivery path, reduce latency and overcome inherent mobile network issues to increase the overall network utilization, untapping the network’s true potential.

Infrastructure Savings

Operators can achieve substantial CAPEX and OPEX savings by drastically reducing the amount of backhaul infrastructure investment needed to support the rapid growth in bandwidth demand. By leveraging open caching at the eNodeB for video delivery, service providers can prepare their networks for the future of online video.

Optimal QoE

Operators can ensure a quality, immersive experience every time by delivering video from close proximity to the subscriber. With an open caching solution, high quality video is always delivered in the original content provider fidelity, without the pesky disruptions, lengthy download times, and control response delays.

Minimize Your Infrastructure Spend

Your mobile network is currently not used to it’s full potential. Video is the most dominating content type and it was not designed to handle the unique conditions a mobile network creates. Deploying an open caching solution means that you can extract more value from your existing network spend and enable your network to support rapidly increasing video traffic. Rather than continually investing budget and resources into acquisition and deployment of costly equipment just to keep up with the required network capacity, operators can maximize the return on investment from their existing infrastructure while making strategic investments to create a more agile and robust network.

Offloading Traffic to Caches Helps Reduce and Minimize Infrastructure Investment Costs

Reduce Operational Costs

A Video Fabric Controller can reduce the amount of OTT video traffic in your network by up to 80%. With video traffic exceeding 50% of total bandwidth in most markets, this reduction translates into substantial savings on bandwidth, peering, and other transit-related costs. A unified video delivery solution requires less rack space, energy, and management effort by the network operations staff.

Open Video Caches Reduce OPEX Operational Costs and Transit Costs

Improve Subscriber QoE

In a highly competitive market where end user satisfaction ranks among top differentiators, a Video Fabric Controller enables carriers to take subscriber QoE to previously unattainable levels. Next-generation open caching solutions are designed and engineered specifically for high demands of video delivery at the subscriber edge, capable of delivering a maximum number of concurrent streams to a large number of subscribers while ensuring content originator’s fidelity and optimizing the end user QoE.
