Abstract
A system may be provided which is operable to determine a routing node for a data object. The system can comprise an identifier generator operable to generate an identifier for the data object on the basis of data content thereof, and a lookup engine operable to compare the identifier for the data object to a routing table to determine a routing node for the data element.
Claims16
A distributed storage system comprising:
- a storage agent operable to perform a look-up in a routing table to determine a routing node for a data object on the basis of an identifier therefore, the identifier for the data object being based on data content thereof, and to send a message including the identifier relating to that data object to the identified routing node;
- and
- a plurality of routing nodes, each operable to perform a look-up in a routing table to determine a further routing node for a data object described in an identifier included in a message received at the routing node, and to forward the message to the identified further routing node;
- wherein at least a subset of the routing nodes are each operable to store data objects having an identifier within a predetermined range, and wherein the routing table for each such node indicates that the further routing node is the current node for identifiers within said predetermined range.

A distributed storage system comprising:
- means for performing a look-up in a routing table to determine a routing node for a data object on the basis of an identifier therefore, the identifier for the data object being based on data content thereof, and for sending a message including the identifier relating to that data object to the identified routing node;
- and
- a plurality of routing means, each for performing a look-up in a routing table to determine a further routing means for a data object described in an identifier included in a message received at the routing means, and for forwarding the message to the identified further routing means;
- wherein at least a subset of the routing means are further for storing data objects having an identifier within a predetermined range, and wherein the routing table for each such routing means indicates that the further routing means is the current routing means for identifiers within said predetermined range.
