An SRV record is a DNS record, which is used to forward a domain to a third-party server and use it for a service different from a web site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is created, you are able to specify an Internet Protocol that the domain name will use and the port, which is to be employed to connect to the remote server. Furthermore, provided that you have a few SRV records for the same service, you can set individual priorities and weights for every one of them, in order to spread the load between several machines. Such a record will enable you to employ the same domain address or subdomains under it with different companies, so you're able to employ it for different purposes even if you are unable to get all the services from just one provider.
