File Downloads And Software Updates

Data Sheet


A constant for smart phone, PC users, video game players, and any user of the many products that are part of daily life, is the periodic need to download software and file updates. Provide users with a great download experience and you enhance their desire to remain a customer. Don’t let things go wrong with a download and turn them off and risk bad word of mouth. Limelight’s Download Solution solves the challenges unique to each download scenario.

Challenges: Continuously Growing Download Sizes and Global a User Base

Download file sizes increase with every release as new capabilities and features are added. Distributing massive downloads to a large global user base and living up to user expectations for a fast and robust experience is challenging.

Addressing These Challenges

Limelight’s Download Solution ensures your file and software updates are optimally delivered with the lowest latency, best reliability, and highest origin offload. These services are part of Limelight’s powerful edge services platform, which integrates a massive global private infrastructure, advanced content delivery capabilities, and support services.

CDN Origin Storage and edge caching allows you to position large software and file downloads at CDN edges near where your users are located. This speeds time to download and protects your origin from large numbers of requests. The solution allows you to access powerful analytics such as download completion rates, download receipts, and traffic patterns, for smarter business decision-making.

  • Edge Caching—Caching large objects to reduce cost and improve delivery performance.
  • ARC Light Computed Edge Policies—ARC Light enables Content Delivery Services to bring compute to the edge. User request and origin responses are modified in realtime to increase speed to content and offload complex business logic from your application infrastructure.
  • SmartPurge—Realtime purge with instant global content invalidation, deletion and purge verification, including purging by content tag and dry run capabilities.
  • IP Protocols—IPv4 and IPv6 Internet protocols supported.
  • HTTP Protocol Support—HTTP/2 supported.
  • Dedicated VIPs—A set of dedicated IP addresses for delivery of “zero-rated” traffic into carriers.
  • Rate Limiting—Large downloads can be rate limited, capping the data transfer rate allocated to each delivery.
  • MTLS—Mutual TLS is a type of mutual authentication in which the origin server and the receiving end point authenticate each other using the TLS protocol for encrypting communications.
  • Global Scale—Limelight’s CDN has the global reach and scale to deliver the largest downloads to massive user bases.


Delivering software downloads and device updates is no easy task. Although the components may seem simple, optimizing them is not. In order to provide the best possible download experience for your end users, you need to fine-tune three critical features of your workflow—the speed at which you deliver your files, the availability of your downloads, and the security of your file-based content. Limelight’s solutions ensure that your files are delivered quickly to your users regardless of where they are, so that you can focus on product development.
