Broadpeak uses AWS Wavelength and 5G for video delivery

Broadpeak, a content delivery network (CDN) provider based in Cesson Sevigne, France, is deploying its advanced CDN technology on AWS Wavelength for streamlined video delivery over the 5G network. 

By leveraging Multi-Access Edge Computing (MEC) and AWS Wavelength, Broadpeak’s local cache servers can directly serve the video traffic requested by local 5G devices instead of having the content streamed from a more distant location. The company says its approach allows video service and content providers to dynamically manage and precisely adjust their CDN capacity based on localized spikes in consumer demand.

“Video streaming is soaring, and with the global rollout of 5G infrastructure, the industry needs more efficient methods for video delivery over next-gen mobile networks. As leaders in 5G and cloud video delivery technologies, we’re excited to help pave that path,” said Jacques Le Mancq, CEO at Broadpeak. “We see MEC as a key enabler for providing a more compelling quality of experience for video streaming over 5G networks. By running our local edge caches on AWS Wavelength, Broadpeak will empower the delivery of immersive experiences, such as 4K video and virtual, augmented, and mixed reality, which are difficult to scale to large audiences today.”

Optimized for MEC applications, AWS Wavelength embeds AWS compute and storage services at the edge of the 5G network so that developers can serve edge computing use cases that require ultra-low latency. By streaming video content from the very edge of the 5G network — closer to end users, Broadpeak’s local cache servers on AWS Wavelength are designed to deliver low-latency, help reduce congestion, and enable video streaming experiences with faster startup times, no rebuffering, and uninterrupted viewing sessions.

Google sharpens Cloud CDN with external origins

Google Cloud has enhanced its CDN and HTTP(S) Load Balancing services with the ability to support hybrid cloud customers. The new capability add support for external origins, enabling customers who have content, workloads or services that are on-prem or in other clouds to benefit of high availability, low latency, and convenience of a single anycast virtual IP address that HTTP(S) Load Balancing and Cloud CDN.  This means Google CDN customers can pull content or reach web services that are on-prem or in another cloud, using Google’s global high-performance network.

The new hybrid configuration are the result of new internet network endpoint groups, which allow the customer to configure a publicly addressable endpoint that resides outside of Google Cloud, such as a web server or load balancer running on-prem, or object storage at a third-party cloud provider. From there, the customer can serve static web and video content via Cloud CDN, or serve front-end shopping cart or API traffic via an external HTTP(S) Load Balancer, similar to configuring backends hosted directly within Google Cloud.

Reliance JIO and Cisco collaborate on Multi-Access Edge Computing

Cisco and Reliance Jio are collaborating in multi-access edge computing. The companies are developing a use case to optimize and enhance video experience over the network by building a mobile content delivery network (CDN). In this concept, the CDN is integrated into the mobile LTE network with edge caches in close proximity to the mobile users.

The idea with a mobile CDN is for the mobile operator to deliver content via edge cloudlets to provide a better user experience with lower latency and higher performance.

Cisco said its mobile CDN work with Reliance Jio uses a combination of IP address management techniques based on the mobile core, requiring tight integration between edge cache, mid-tier cache, and the traffic router in the Cisco Open Media Distribution system. The mobile core and the Cisco Open Media Distribution are combined into one system level solution for the CDN embedded in the mobile network.

To solve the problem of user plane selection, the system uses Control/User Plane Separation (CUPS) as defined in 3GPP R14.

Cisco and Reliance Jio also solved the issue of assigning a geographically appropriate IP address to the mobile device and the issue of handover resiliency in the face of IP address changes on the client side and the CDN cache site without change or disturbance to the current services.

Google Cloud Builds Global Content Delivery Network Partnerships

Google announced collaborations with four of the industry’s leading content delivery network (CDN) providers: CloudFlare, Fastly, Highwinds, and Level 3 Communications.

The new CDN Interconnect program enables the customers of these CDN providers and the Google Cloud Platform to pay reduced prices for in-region Cloud Platform egress traffic (to approved CDN locations).

Google said this CDN Interconnect program will encourage the best practice of regularly distributing content originating from Cloud Platform out to the edge close to end-users. Google provides a private, high-performance link between Cloud Platform and the CDN providers, allowing content to travel a low-latency, reliable route from the Google data centers out to the end users. Google is recommending that publishers on the Google Cloud Platform to also use a CDN provider especially for heavy, frequently accessed content.

Google's network footprint currently extends to 70 PoPs in 33 countries.

Level 3 Content Delivery Network is in 90+ major metro cities globally.

CloudFlare posted the following explanation: 30 CloudFlare points of presence (PoPs) are directly connected to Google Cloud Platform’s infrastructure. When one of these CloudFlare PoPs requests content from a Google Cloud Platform origin, it’s routed through a high-performance interconnect instead of the public Internet. This dramatically reduces latency for origin requests, and it also enables discounted Google Cloud Platform egress pricing in the US, Europe and Asia regions.

As of May 1st, Fastly has nine points of presence (POPs) interconnected with Google: San Jose, Los Angeles, Dallas-Fort Worth, Chicago, New York, Ashburn, Frankfurt, London, and Tokyo.

Blueprint: Next Gen Mobile Video Optimization

Mobile Streaming is the Future – It’s Also the Problem We Must Solve

by Mark Fisher, VP Marketing and Business Development at Qwilt

To be sure, streaming video really is the future. The online video phenomenon is creating a market and technology transformation that rivals some of the greatest technology disruptions in history. Just like the disruption of broadcast radio and cable television in their day, streaming video is transforming both consumer behaviour and business models. While the early days of online video were novel, limited to watching clever three minute YouTube videos, it was the advent of long form HD video from sources like Netflix, Amazon and Hulu that ushered in a new generation of viewers.

For many of us with a Netflix account, the notion that you once had to wait for a TV show to come on air in order to view the broadcast already seems laughable. But, the implications for consumers worldwide and the network operators who serve them are profound. We have reached a point where the 40 year old and highly asymmetrical model of broadcast television is being turned upside down. Consumers are now fully in charge – they choose the content, device, time and place. As such, many cable operators are beginning to recognize and, in some cases, admit publicly, that as time goes on, their broadband internet service offering, not their cable TV service, will be their strategic product line.

Furthermore, this transformation ripples out in many directions. High quality video streaming is not only making its way into our living rooms, via the popular uptake of connected smart TVs, but increasingly onto our mobile devices too. Today’s viewers expect to be able to watch their favorite TV show or film, anytime, anywhere and on any device, such as a smartphone or tablet. With research showing that more than half of a mobile viewers’ time is spent watching videos that are longer than 30 minutes, and live streaming of sporting events looming as the next tidal wave to hit mobile networks, it is clear that streaming really is the future. Therefore, it is critical that operators prepare their networks for the future of online video, or else customer satisfaction and retention will be at stake.

This transformation has even more profound implications for mobile networks for two reasons. First, 4G and 5G access speeds now rival fixed broadband performance in many regions. And second, the vast majority of consumers in the coming years will rely on mobile broadband services as their sole access to the Internet. According to Cicso’s 2015 VNI report, by 2019, 4.6 billion smartphones users will drive 97 percent of all mobile data and 72 percent of this mobile traffic will be streamed video. So, the implication for mobile network architects is that consumer will increasingly expect a “broadcast TV” experience while streaming video to a mobile device.

The Problem: Packet loss, Buffer Bloat and Latency

Driven predominantly by the mainstream adoption of over-the-top (OTT) services from popular video-on-demand services like Netflix, Hulu, Amazon and from live-streaming sources like ESPN, NBC and Twitch, this exponential growth in demand for content will push existing mobile networks to their limits. Today’s mobile network operators face two unique challenges: first, they must optimize streaming video traffic so as to make efficient use of expensive RAN resources and, secondly, they must ensure Quality of Experience (QoE) for viewers who expect a high-quality, mobile viewing experience that rivals that of ‘broadcast TV’. The new mobile video optimization architecture must simultaneously resolve these two critical challenges – traditionally at odds with each other.

The technical performance problem faced by mobile networks given their current architecture is twofold: first, packet loss and buffer bloat across the RAN results in under-utilized Radio resources and second, latency and packet loss across the backhaul network and through the packet core result in underutilized and congested backhaul networks. The increasing amount of streaming video traffic on mobile networks exacerbates both of these problems as the streams are delivered from origin servers upstream of the packet core. The aggregate latency across this network path, from core to RAN, is a key driver for the downstream problems of packet loss and buffer bloat, which greatly hamper RAN efficiency. These conditions call for a new mobile architecture to address the onslaught of streaming video.

A New Architecture is Needed

Conventional wisdom would guide an operator to address this problem with brute force – buying more routers, switches and links to increase capacity. This is no longer a scalable or cost-effective approach. Choosing an intelligent open architecture and open caching solution can dramatically reduce the volume of repetitive streams clogging up the network by identifying, storing and delivering the most popular, high-quality video content from inside the service provider network. It’s interesting to note that an effective open architecture and open caching platform can reduce streaming video traffic demands by as much as 60 to 80 percent in some cases.

The Solution – Move Content To The Edge

At the heart of the new mobile network architecture is a simple principle: move content to the edge of the network, as close as possible to consumer.

From a technical perspective, this new architecture calls for an open caching function, which is integrated with the eNodeB. There are already a number of disruptive forces at work in mobile architecture, including the notion of a Cloud RAN, which employs innovative front haul technology. This virtual RAN architecture can be deployed at a fraction of the cost of conventional systems. The integration of an open caching layer at each eNodeB can be accomplished through Network Function Virtualization (NFV) as the caching function can be enabled entirely through software running on commodity hardware. Furthermore, this NFV-based cache can use local compute and storage resources as needed to manage content at peak demand, when resources are strained. During after peak hours, the compute and storage resources can be assigned other tasks leveraging the NFV architecture.

In combination, this new open caching architecture dramatically reduces network latency and, pivotally, improves viewer QoE. Resulting in substantial increase in RAN efficiency and dramatic improvement in capital utilization, hidden network capacity is unlocked. In addition, mobile operators can optimize their backhaul capacity spend, thereby tackling the next bottleneck in LTE networks.

Ultimately, this new mobile architecture results in a substantial reduction in end to end latency. The impact on RAN utilization is significant as radio resources are able to manage streaming content with greater efficiency. Many technology providers expect this new architecture to improve RAN efficiency by 20 to 30 percent. So, at the end of the day, this new architecture will allow mobile operators to continue to leverage current radio network assets, unlocking capacity that would have otherwise been lost.

Consumers have spoken – It’s time to build the new network for mobile video

As network operators and the technology companies that support them, we don’t have the luxury of pondering the outcome – consumers have spoken. They love the freedom and choice that comes with this new model of streaming video. It’s up to us now to create the infrastructure in mobile networks that will profitably support this new model of consumption.

The Internet can certainly be relied on to deliver television, but only if network traffic is managed appropriately. Given that video is swiftly becoming a standard fixture in the consumer web experience, and deterioration in end-user Quality of Experience (QoE) can drive churn, operators must have the right network architecture as a starting point. It is this new architectural foundation that will allow mobile operators to deliver the future of streaming video to the consumers who want it so desperately.

ETSI's Mobile-edge Computing ISG Gets Underway

ETSI’s newly created Mobile-edge Computing (MEC) Industry Specification Group (ISG) kicked off its development work earlier this month with a first meeting hosted by Nokia Networks in Munich. The group is aiming to complete five documents by mid-2015: Terminology, Service Scenarios, Technical Requirements (including use cases and their benefits), a Proof of Concept Framework leading to a Framework and Reference Architecture. When the first documents get to the required maturity level, work on platform services, APIs and interfaces will commence.

Mobile-edge Computing provides IT and cloud-computing capabilities within the Radio Access Network (RAN) in close proximity to mobile subscribers. Located at the base station or at the Radio Network Controller, it also provides access to real-time radio and network information such as subscriber location or cell load that can be exploited by applications and services to offer context-related services.

For application developers and content providers, the RAN edge offers a service environment characterized by proximity, ultra-low latency, high-bandwidth, as well as real-time access to radio network information and location awareness. Mobile-edge Computing allows content, services and applications to be accelerated, maintaining a customer’s experience across different radio and network conditions.

So far, the MEC ISG has attracted 24 member and participant organizations, including network operators, vendors, technology suppliers and content delivery network (CDN) providers.
