Open Caching

Open video caching reduces bandwidth consumption by up to 80%



Watch Video: What is Open Caching?

An open cache identifies data that’s frequently sent in network traffic, caches it locally, and delivers it from the network edge when requested – without requiring any change of behavior or business logic by content providers, CDNs, or subscribers.

The challenge with caching video is doing this seamlessly and efficiently to ensure optimal subscriber experience, preserve content provider’s fidelity – while reducing the strain of video traffic on the network.

The 80/10 Rule of online video caching

The 80/10 Rule of online video caching

In most service provider networks, over 80% of video volume is typically consumed by only 10% of titles. This means that most of the traffic volume consists of duplicate titles repeatedly traversing the network and causing congestion.

Open Caching is the Cost-Effective Approach to Bandwidth Management

Stop Throwing Routers at the Problem

In the past, the only way to increase capacity was by adding more costly infrastructure. But as consumer demand for bandwidth continues to soar, simply adding more routers is no longer a scalable or cost-effective approach.

An intelligent open caching solution can dramatically reduce the volume of repetitive traffic by identifying, storing and delivering the most popular, high-quality video content from inside the service provider network.

Common Problems in Networks

Without Open Caching

Service Provider Networks Without Open Caching Experience Congestion and QoE Issues

Growing Transit Costs

Even when a high percentage of subscribers are watching the same titles, each video has to be delivered directly (over-the-top) from the content provider every time it is requested. The redundant streams exponentially increase the total amount of bandwidth, and results in high transit costs for operators.

Network Congestion

Each over-the-top (OTT) video has to traverse the entire network to get to the subscriber. The increased traffic load during peak video consumption hours causes network congestion, which impacts performance and QoS for all services, including video and other latency-sensitive applications.

Costly Infrastructure

As video consumption continues to grow and shift from short single-file clips like Youtube, towards full-feature HD titles like Netflix, service providers are forced to heavily invest into costly network infrastructure to continually expand capacity needed to meet the growing bandwidth demand.

Poor Quality of Experience

Long transit from content sites and network 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.

Key Improvements in Networks

With Open Caching

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

Reduced Bandwidth Costs

Open caching minimizes the number of times video titles are delivered from the content provider sites, which substantially reduces the total volume of data crossing the transit links. Popular, frequently viewed videos are identified, stored, and delivered to subscribers from within the network.

Robust Network

As the overall volume of OTT video traffic traversing the service provider network decreases, network conditions improve dramatically even during peak consumption periods. This improves performance for all other bandwidth-sensitive non-cacheable network traffic, applications, and services, and non-cached video content.

Infrastructure Savings

Operators can achieve substantial CAPEX savings by drastically reducing the amount of infrastructure investment needed to support the rapid growth in bandwidth demand. By leveraging open caching 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.

Caching and the Video Delivery Ecosystem

Open caching adds tremendous value for all members of the video delivery chain – creating a symbiotic ecosystem of network operators, content providers, CDN operators, and subscribers.

Why Should Network Operators Deploy a

Open Caching Solution?

Minimize Your Infrastructure Spend

It’s time to stop throwing routers at the problem. Deploying an open caching solution at the subscriber edge substantially reduces the need for costly network-wide infrastructure upgrades 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.
