Video is a unique data format. It is impacted by network latency and dropped data packets differently than other information types because even the smallest delay in getting data to users can lead to performance problems. An enterprise content delivery network can use software-defined technologies to help you deal with video challenges, and a few issues it is particularly useful in combating are:
1. Dropped data packets are intolerable
Most Ethernet systems are designed to automatically drop data packets if the network is overloaded and automatically resend that packet. This can lead to millisecond delays – and slowdowns that are even longer when other forms of latency emerge on the network. This isn’t a big deal for most data types, but video can end up stalling and buffering if data packets are dropped, with the impact on the end-user experience being far greater than the small delay experienced in the network.
ECDNs use intelligent routing functions that come from software-defined technologies ensure that video data packets move smoothly through the network and get to users without disruption.
2. Capacity demands are overwhelming
Dropped data packets aren’t the only issue that come into play with video. Sometimes video packets are so large that even moving one through the network can completely fill your WAN’s capacity or clog any bottlenecks that exist within your LAN. Intelligent routing may get your video through the network well, but productivity can still decline for users not consuming video because the data types they are depending on are getting delayed because of video.

Capacity is a major problem, but ECDNs don’t just route data intelligently, they do so without being limited by the typical restrictions of layered network pathways. SD technologies allow the network to share hardware resources across the configuration, making it much easier to overcome capacity challenges without adding hardware to the system.
3. Consumption can escalate quickly
Video streaming within your organization can get out of hand so quickly that network systems can struggle to keep up. It is one thing to have a few users leveraging a data-rich application. That will put a burden on the network, but it is nothing compared to having half of your company attending a livestream of a meeting. The data consumption escalation that comes with video can be overwhelming.
This is another area where the ability to use hardware resources freely is key, as you can eliminate bottlenecks and make sure data moves to each user in the best route – preventing the network from being overwhelmed.
