Abstract

A method and system for transmitting data including pieces of data. The method includes the steps of: placing a piece of data on at least one cache memory; and sending a signal indicating a presence of the piece of data on the cache memory to at least one client, where at least one of the steps is carried out by a computer device.

Claims

1. A server system comprising:

a repository memory;

a cache memory;

a network interface; and

a processor configured to;

place a piece of data on at least one cache memory, wherein said piece of data is a block of data constituting the whole data that are to be transmitted; and

send a signal indicating a presence of said piece of data on said cache memory to at least one client.

2. A client system comprising:

a memory;

a network interface; and

a processor configured to;

receive a signal indicating a presence of a piece of data on a cache memory, wherein said piece of data is a block of data constituting the whole data that are to be transmitted.
