US 2020/0396200 A1 · USING DNS TO COMMUNICATE MP-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.

Dependent claims

A domain name system (DNS) device comprising:

a memory configured to store a list of Internet protocol (IP) addresses for a set of hostnames, at least one of the hostnames having two or more IP addresses, the memory further storing data representing, for each of the IP addresses, whether a network device corresponding to the IP address is capable of performing multipath transmission control protocol (MP-TCP), the network device being part of a set of network devices;
and
one or more processors implemented in circuitry and 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 of the IP addresses corresponding to the hostname and corresponding to one of the network 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.

A method comprising:

receiving, by one or more processors of a domain name system (DNS) device, a DNS query from a client device, the DNS query including a specification of a hostname and a request for an MP-TCP capability, wherein the DNS device comprises a memory configured to store a list of Internet protocol (IP) addresses for a set of hostnames, at least one of the hostnames having two or more IP addresses, the memory further storing data representing, for each of the IP addresses, whether a network device corresponding to the IP address is capable of performing multipath transmission control protocol (MP-TCP), the network device being part of a set of network devices;
determining, using the memory, at least one of the IP addresses corresponding to the hostname and corresponding to one of the network devices that is MP-TCP capable;
and
sending, by the one or more processors, a DNS response to the client device, the DNS response including an indication of the at least one of the IP addresses.
