An SRV record is a DNS record, that is used to forward a domain name to a third-party server and employ it for some service different from a website. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you could specify an Internet Protocol which the domain name will use and the port, which will be employed to connect to the remote server. Moreover, if you have a few SRV records for the same service, you could set different priorities and weights for every one of them, allowing you to distribute the load between a number of machines. Such a record will enable you to use the same domain address or subdomains under it with different providers, so you can use it for various purposes even if you are not able to get all of the services from one provider.
