Can you explain what a media server is and how it relates to or differs from a media gateway? What are media servers used for, and how would they be useful in an environment running voice or video?
A media server stores and provides videos or voice to end users. A media gateway is a device that provides protocol translation services to control how the content is delivered to end users. Media servers are a very effective way of distributing voice and video. Depending on how the servers and the network are configured, both media gateways and servers may be required to distribute voice and video.
Probably the easiest example to understand is a service like Netflix. Netflix has many media servers that store movies and television shows for its users. A gateway may change the protocol to deliver the media to users based on their network, end device and capabilities at both ends. This sets up a session so users can view the media stream.
