Node and method to provide and keep real-time up-to-date data in a distributed hash table

A node, comprising:

• means for creating a finger table;
• means for subscribing to changes in a network address of at least one other node included in the finger table;
• means for receiving at least one notification including an identifier and a network address of the at least one other node;
• and
• means for updating the finger table with the new network address of the at least one other node received in the at least one notification.

A node, comprising:

• means for creating a reverse finger table;
• means for receiving subscriptions to changes in a network address of the node from at least one other node;
• means for storing the network address of the at least one other node in the reverse finger table;
• and
• means for sending a notification of a new network address from the node to the at least one other node in the reverse finger table when the network address of the node changes.

A node, comprising:

• means for creating a neighbor table;
• means for learning network identifiers and/or network addresses of neighbor nodes;
• means for storing the network identifiers and/or network addresses of neighbor nodes in the neighbor table;
• and
• means for sending a notification of a new network address to the at least one other neighbor node in the neighbor table when the network address of the node changes.

A node comprising:

• means for creating a neighbor table, configured to learn network identifiers and/or network addresses of neighbor nodes;
• means for storing the network identifiers and/or network addresses of neighbor nodes in the neighbor table;
• means for receiving a notification of a new network address from the node at the at least one other neighbor node stored in the neighbor table;
• and
• means for updating the neighbor table of the at least one other neighbor node with the new network address from the node.

A method, comprising:

• creating a finger table at a node;
• subscribing to changes in a network address of at least one other node included in the finger table;
• receiving at least one notification including an identifier and a network address of the at least one other node;
• and
• updating the finger table with a new network address of the at least one other node received in the at least one notification.

A method, comprising:

• creating a reverse finger table at a node;
• receiving subscriptions to changes in a network address of the node from at least one other node;
• storing the network address of the at least one other node in the reverse finger table;
• and
• when the network address of the node changes, sending a notification of a new network address from the node to the at least one other node in the reverse finger table.

A method, comprising:

• creating a neighbor table at a node;
• learning network identifiers and/or network addresses of neighbor nodes;
• storing the network identifiers and/or network addresses of neighbor nodes in the neighbor table;
• and
• when the network address of the node changes, sending a notification of a new network address from the node to the at least one other neighbor node in the neighbor table.

A method, comprising:

• creating a neighbor table at a node;
• learning network identifiers and/or network addresses of neighbor nodes;
• storing the network identifiers and/or network addresses of neighbor nodes in the neighbor table;
• receiving a notification of a new network address from the node at the at least one other neighbor node stored in the neighbor table;
• and
• updating the neighbor table of the at least one other neighbor node with the new network address from the node.
