Failover in an internet location coordinate enhanced domain name system
First Claim
1. A system comprising:
- memory;
at least one processing unit of a client computing device, wherein the at least one processing unit is communicatively coupled to the memory;
instructions stored in the memory and executable by the at least one processing unit, the instructions to;
request resolution of a domain name using a Domain Name System (DNS) protocol;
receive, in response to the request, a list of Internet protocol (IP) addresses and Internet Location Coordinates (ILCs) for host servers associated with the domain name, the ILCs for the host servers being determined based at least in part on communication with network beacons by the host servers;
respond to a connection problem to a host server at an IP address by selecting a different IP address from the list, the selecting the different IP address comprising comparing an ILC of the client computing device, as determined based at least in part by the client computing device sending packets to network beacons, with an ILC of a different host server at the different IP address, as determined based at least in part by the different host server sending packets to network beacons; and
initiate a connection to the different host server at the selected, different IP address, the client computing device being configured to connect to at least one of a plurality of host servers.

Abstract
An exemplary failover module includes (a) instructions to respond to a connection problem to a host server at an IP address by selecting a different IP address from a cached list of IP addresses for a domain name associated with the host server and (b) instructions to return the selected, different IP address to future name queries where the instructions to respond, the instructions to initiate, and the instructions to return execute at an operating system level of a computing device configurable to connect to at least one of a plurality of host servers. Such a module may include instructions to optionally initiate a connection to a host server at the selected, different IP address. An exemplary failover module may optionally select an IP address based in part on Internet Location Coordinates (ILCs) where the host servers reside in an ILC enhanced Domain Name System (DNS). Other methods, devices and systems are also disclosed.

memory; at least one processing unit of a client computing device, wherein the at least one processing unit is communicatively coupled to the memory; instructions stored in the memory and executable by the at least one processing unit, the instructions to; request resolution of a domain name using a Domain Name System (DNS) protocol; receive, in response to the request, a list of Internet protocol (IP) addresses and Internet Location Coordinates (ILCs) for host servers associated with the domain name, the ILCs for the host servers being determined based at least in part on communication with network beacons by the host servers; respond to a connection problem to a host server at an IP address by selecting a different IP address from the list, the selecting the different IP address comprising comparing an ILC of the client computing device, as determined based at least in part by the client computing device sending packets to network beacons, with an ILC of a different host server at the different IP address, as determined based at least in part by the different host server sending packets to network beacons; and initiate a connection to the different host server at the selected, different IP address, the client computing device being configured to connect to at least one of a plurality of host servers. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A method for failover, implemented by a computing device, the method comprising:
-
requesting, by the computing device, resolution of a domain name using a Domain Name System (DNS) protocol; receiving, in response to the requesting, a list of Internet protocol (IP) addresses and Internet Location Coordinates (ILCs) for host servers associated with the domain name, the ILCs for the host servers being determined based in part on communication with network beacons by the host servers; selecting, by the computing device, a first IP address from the list; recognizing a connection problem to a host server associated with the first IP address; selecting, by a failover module operating at an operating system level of the computing device, a second IP address from the list, wherein the selecting the second IP address comprises comparing an ILC determined by the computing device based in part on sending packets to network beacons with one of the ILCs determined by a different host server at the second IP address; and returning, by the failover module operating at the operating system level of the computing device, the second IP address to further DNS queries for the given domain name. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method for failover, implemented by a client computing device, the method comprising:
-
acquiring an Internet Location Coordinate (ILC) based at least in part on communication, by the client computing device, with network beacons; requesting, by the client computing device, resolution of a domain name using a Domain Name System (DNS) protocol; receiving, in response to the requesting by the client computing device, a list of Internet protocol (IP) addresses and Internet Location Coordinates (ILCs) for host servers associated with the domain name, the ILCs for the host servers being derived based in part on communication with network beacons by the host servers; comparing, by the client computing device, the ILC of the client computing device with the ILCs for the host servers; selecting, by the client computing device, an IP address from the list based at least in part on the comparing; recognizing, by the client computing device, a connection problem to the host server associated with the IP address; selecting, by the client computing device, a next IP address from the list based at least in part on the comparing; and establishing, by the client computing device, a connection to the host server at the next IP address. - View Dependent Claims (19)
