Network operators need to rethink CDNs for 5G, says Varnish, as it offers tech solution

Varnish Software has launched a new, 5G-ready content delivery network (CDN) that enables customers to build new services that harness the power of 5G and mobile edge computing (MEC). Varnish Edge Cloud is a carrier-grade, 5G-ready virtualized CDN and edge caching software solution that enables 150Gbps throughput from a single node, sub-millisecond time-to-first-byte latencies and 100,000 concurrent users per node. It also offers efficient storage and caching of 100TB of data on each node, high-speed TLS termination, dynamic cache placement, and 24/7/365 support with monitoring, alerting and incident response. Espen Braastad, VP Engineering at Varnish Software, says: “Varnish Edge Cloud enables our partners to match the speed gains that 5G makes possible while protecting the core network and origin servers from huge demand.”

Varnish Edge Cloud enables network providers to handle more client requests with less infrastructure utilisation. Offered with a fully managed service option, it helps operators offer new services and exploit revenue opportunities that will stem from 5G access networks, starting with streaming video as the dominant subset of enhanced mobile broadband services.

“With 5G rollout accelerating across the globe, and operators faced with growing consumer appetites for high-fidelity video, user-generated content and new experiences like virtual reality, traditional content delivery networks will struggle to match 5G for speed and capacity,” Varnish Software declares. “As third-party services running on telecommunications hardware, these CDNs also miss out on optimal resource utilisation. Network operators therefore have an opportunity to take control of content distribution on their networks and offer these 5G services themselves.”

The cache capacity of Varnish Edge Cloud nodes is the key to giving telcos greater control. These also scale on demand, whether deployed at the network edge in virtualized PoPs, in aggregate data centres or between 5G base stations. “This highly elastic, cloud-native technology can handle high density situations, such as those needed in stadiums and city centres, as well as demand spikes from live sports events, season finales and viral content,” the vendor confirms. “The solution is already being used by a major telecommunications service provider, preparing for exactly those eventualities.”

When offered as a fully managed software solution, Varnish staff become an extension of the operator, designing and supporting a network that is unique, based on specific business needs. “We can provide all the expertise, experience and resources required for deploying and running the 5G-ready vCDN [virtualized CDN], overcoming hurdles such as lack of in-house knowledge or timescale concerns,” the company emphasises.

Lars Larsson, CEO at Varnish Software, calls Varnish Edge Cloud the next stage in the evolution of Varnish. “As mobile devices come to dominate how content is accessed, and increasing levels of data processing occur at the network edge, the speed and latency of content delivery is more important than ever. Consumer expectations of 5G have been set high, but to make these a reality, operators are going to have to rethink how they architect their systems, and move storage and caching to the outermost edge of the network.”

Lars Larsson will be explaining why the 5G era requires a new approach to streaming content delivery at Connected TV World Summit. More details here.
