To understand what an eCDN is, how the eCDN technology works, and why its importance for modern communication gets bigger every day, you need to know how a standard CDN works. You can learn more about content delivery networks here.
What is an eCDN?
ECDN stands for Enterprise Content Delivery Network and it saves the same purpose as a traditional CDN: Distributing data. However, an eCDN technology is not designed to deliver data over long distances but to provide all members of a corporate network with a stable flow of data. A corporate network may contain many different end-devices but has often only limited bandwidth available. Imagine a big company building with thousands of employees. Presumably, they all work in a digital workplace, and usually, the applied amount of bandwidth is enough for their daily work. But when a mass of data is required, e.g. for streaming a video for your employees, network congestions can’t be prohibited without an eCDN technology.

How does an eCDN work?
In general, there are different ways of how an eCDN can reduce the amount of data that has to slap through a firewall. Some companies are using an eCDN based on multicast or caching technology, and others rely on Peer-to-Peer software. StriveCast has developed a P2P eCDN solution, which is pretty appropriate to solve bottleneck problems in streaming situations. Using a P2P-based eCDN technology makes sure, that not every user within a corporate network connects to the source. When even a few do, there won’t be any problems with network congestion anymore. The extant viewers are provided with data by building a sharing network of all corporate network members. If you want to learn more about our P2P eCDN solution, you can find more information here.
Applications of an enterprise Content Delivery Networks
Enterprise Content Delivery Networks are often used when companies need to distribute large amounts of data within their corporate network. A typical application is the delivery of live and on-demand video data, as for example:
- Live video transmission of internal events like digital town hall meetings
- Regularly delivering (enterprise) webcasts to a large audience
- Setting up enterprise live streams within a corporate network
- eLearning sessions for customers, partners, and employees
- Every live streaming application for your corporate communications
- Efficient delivery of live streams for hybrid events like exhibitions and conferences
The main purpose of an eCDN is to enable live video streaming in corporate environments by smartly distributing data to avoid network congestion. However, this is not the only advantage an eCDN brings to the table: most eCDNs are flexible in their use cases. eCDN users profit from better video quality, higher viewer satisfaction, or time savings through complete solutions. Here is an overview of the most important benefits of an eCDN (depending on the provider):
- Bandwidth reduction for video delivery
- Reducing buffering times of the video
- High-quality video streaming
- Scalability to thousands of users
- Minimized latency for live video streams
- Making digital events possible even in limited infrastructures
- Freeing up bandwidth for other business-relevant processes
Different eCDN Technologies
The eCDN providers in the market rely on three different techniques of distributing data: multicast, caching, or peer-to-peer.
A peer-to-peer (P2P) eCDN connects the devices within the company network. It then distributes video content between all connected devices that are streaming the same video content. By sharing their data instead of requesting it individually, companies can save a significant amount of bandwidth while increasing network reliability.
A Multicast eCDN uses the multicast communication protocol to send large amounts of data (e.g., a video stream) simultaneously to several end devices. With multicast video delivery, the origin server sends the stream or data file once to a multicast address, distributing packets to all recipients in the multicast network. This way, network traffic is reduced as devices no longer separately request and pull an independent stream from the origin server.
eCDN with Video Caching
An eCDN based on video caching, stores data in caching servers, which then deliver the video to the viewers. Usually, there are several local caching servers on each office location, enterprise network, or subnetwork. When people within the intranet request the stream or video data, the local cache is checked first before contacting the origin server. If available, the viewer then receives the data directly from the local cache.
