Synchronizing services across network nodes

A method of synchronizing a network-enabled device with other devices on a network, comprising:

• accessing peer nodes of network-enabled devices on the network;
• executing at least a node service and a service repository service on the network-enabled device, wherein the service repository service maintains a service list which includes services available locally at the network-enabled device and services available remotely at peer nodes, wherein the node service manages synchronized access to the service list of the service repository service by multicasting a change notification responsive to a change in the services available locally at the network-enabled device, and by listening to multicasts of change notifications from peer nodes, and
• wherein responsive to a change in services available locally at the network-enabled device, the method further includes:
• collecting by the node service a list of services locally at the network-enabled device;
• generating a SyncGUID by using a hash function applied to the list of services available locally at the network-enabled device;
• formatting a change notification message which includes the SyncGUID;
• and
• multicasting the formatted change notification message via the network to peer nodes on the network.

A computer-readable storage medium storing computer-executable process steps for causing a computer to perform a method for synchronizing a network-enabled device with other devices on a network, comprising:

• accessing peer nodes of network-enabled devices on the network;
• executing at least a node service and a service repository service on the device, wherein the service repository service maintains a service list which includes services available locally at the network-enabled device and services available remotely at peer nodes, wherein the node service manages synchronized access to the service list of the service repository service by multicasting a change notification responsive to a change in the services available locally at the network-enabled device, and by listening to multicasts of change notifications from peer nodes, and
