Abstract

A method for establishing content indexes includes: determining the size of a content space; determining a content address space according to the size of the content space; establishing the mapping relationship from the content space to the content address space and obtaining the content address; monitoring the corresponding content address and accepting the content publication or the content acquisition request of the content mapping space, by the content indexing node.

Claims

1. A method for establishing content indexes, comprising:

determining a size of a content space;

determining a content address space according to the size of the content space;

establishing a mapping relationship from the content space to the content address space to establish a content mapping space and to obtain a content address;

monitoring the content address; and

accepting a content publication request or a content acquisition request from the content mapping space, by a content indexing node.

2. The method according to claim 1, further comprising:

sending, by the content indexing node, at the content address, a message to identify an existence of the content indexing node.

3. The method according to claim 1, further comprising:

monitoring at least one content address and accepting the content publication request or the content acquisition request from at least one content mapping space, by the content indexing node.

4. A method for publication of contents, comprising:

numbering a content or content identification to obtain a content index number;

converging the content index number according to a masking or modularization rule to obtain a content address; and

storing the content index or content to an indexing node where the content address is located.

5. A method for publication of contents, comprising:

hashing a content or content index to obtain a content index number;

modularizing or masking the content index number.

6. A method for acquisition of contents, comprising:

hashing a content or content identification to obtain a content index number;

masking the content index number according to a content masking rule to obtain a content address; and

monitoring the content address to obtain a content index or content, or sending a request to the content address to obtain the content index or content, or monitoring the content address to obtain a content node address to obtain the content.

7. A method for establishing a content layer, comprising:

joining a network;

monitoring a common address space of the content layer;

determining, by a first indexing node, that there is no content layer node in the network when no action of a content layer indexing node is monitored at the common address space;

periodically broadcasting at the common address spacethat the content layer node has started to work, and accepting a content layer request message from other nodes, by the first indexing node index;

joining the network;

monitoring the periodical broadcast at the common address space;

negotiating with the first indexing node;

acquiring a range of indexing space charged by the second indexing node;

determining, by a second indexing node, a content layer channel at which the second indexing node works;

joining the content layer; and

coordinating, by an Nth indexing node, the works at the content layer,.

8. A content network system, comprising:

a content indexing node configured to manage a content address according to a mapping relationship from a content space to a content address space;

a content node configured to write a content or content index into a content indexing node through a content address channel or a direct connection with the content indexing node; and

a content consumer node configured to obtain the content or content index through the content address channel or the direct connection with the content indexing node.

9. An apparatus for publication of contents, comprising:

a numbering unit configured to number a content or content identification to obtain a content index number;

a content address acquisition unit configured to converge the content index number according to a masking or modularization rule to obtain a content address; and

a storage unit configured to store the content index or content to an indexing node where the content address is located.

10. An apparatus for acquisition of contents, comprising:

a numbering unit configured to obtain a content number from an external source or according to a content identification;

a content address acquisition unit configured to obtain a content address from the content number according to a rule; and

a storage unit configured to store the content index or content to an indexing node where the content address is located.
