Abstract

In one embodiment, a first server computing is configured to send, to a network component, a request to subscribe to a multicast group. In addition, the first server computing device may receive a message sent from a second server computing device to the multicast group. The first server computing device may determine, from the message, an internet protocol (IP) address and port number associated with the second server computing device. In addition, the first server computing device may determine that the first server computing device has not previously received information associated with the second server computing device. The first server computing device may cause a connection to be established between the first server computing device and the second server computing device, the connection for enabling the first server computing device to determine whether the second server computing device offers storage for the first server computing device.

Claims17

Dependent claims

A first server computing device, comprising:

one or more processors;
and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
storing a list for indicating one or more server computing devices that offer storage for the first server computing device;
sending, to a network component, a request to subscribe to a multicast group;
receiving a message, sent from a second server computing device to the multicast group, specifying an internet protocol (IP) address associated with the second server computing device, a port number for connecting to the second server computing device, a protocol supported by the second server computing device, and an indication of whether an amount of storage on the second server computing device has changed;
determining, from the message, the IP address, the port number, and the protocol supported by the second server computing device;
determining, based at least in part on the IP address, that the first server computing device has not previously received information associated with the second server computing device;
determining that the first server computing device also supports the protocol supported by the second server computing device;
and
in response to determining that the first server computing device has not previously received information associated with the second server computing device and that the first server computing device also supports the protocol supported by the second server computing device:
causing a connection to be established between the first server computing device and the second server computing device using the IP address and the port number;
determining, via the connection, that the second server computing device offers storage for the first server computing device;
and
updating the list to indicate that the second server computing device offers storage for future use by the first server computing device.

12 more elements

A method implemented at least in part by a first server computing device, the method comprising:

storing a list for indicating one or more server computing devices that offer storage for the first server computing device;
sending, from the first server computing device and to a network component, a request to subscribe to a multicast group;
receiving, at the first server computing device, a message sent from a second server computing device to the multicast group, the message indicating an internet protocol (IP) address associated with the second server computing device, a port number for connecting to the second server computing device, a protocol supported by the second server computing device, and an indication that an amount of available storage on the second server computing device has changed;
determining, from the message, that the amount of available storage on the second server computing device has changed;
determining that the first server computing device also supports the protocol supported by the second server computing device;
and
in response to determining that the amount of available storage on the second server computing device has changed and that the first server computing device also supports the protocol supported by the second server computing device:
causing a connection to be established between the first server computing device and the second server computing device;
determining, via the connection, that the second server computing device offers storage for the first server computing device;
and
updating the list to indicate that the second server computing device offers storage for future use by the first server computing device.
