Using DNS to communicate MC-TCP capability of server devices

Abstract:

This disclosure is related to devices, systems, and techniques for using a Domain Name System (DNS) server to identify one or more network devices capable of operating according to a protocol. For example, a DNS system device includes a memory and one or more processors implemented in circuitry. The one or more processors are configured to receive, from a client device, a DNS query including a specification of a hostname and a request for an MP-TCP capability, determine, using the memory, at least one IP address corresponding to the hostname and corresponding to one of the devices that is MP-TCP capable, and send, to the client device, a DNS response including an indication of the at least one of the IP addresses.
