Abstract

The invention relates to network equipment (E₁, E₂, E₃) for transmitting data packets, some of which contain requests for a service implemented by a plurality of servers (S₁, S₂, S₃), which network equipment is characterized in that it includes means for receiving data packets containing or referring to executable code adapted to distribute said service requests among said plurality of servers and means for deciding to transmit said data packets to another network equipment or to execute said executable code.

Claims

1. Network equipment (E₁, E₂, E₃) for transmitting data packets, some of which contain requests for a service implemented by a plurality of servers (S₁, S₂, S₃), which network equipment is characterized in that it includes means for receiving data packets containing or referring to executable code adapted to distribute said service requests among said plurality of servers and means for deciding to transmit said data packets to another network equipment or to execute said executable code.

2. A management device (M) associated with a plurality of servers (S₁, S₂, S₃) connected to a network (N) and implementing the same service, which management device is characterized in that it includes means for transmitting to network equipment (E₁, E₂, E₃) executable code (c₁, c₂, C₃) adapted to distribute the requests among said plurality of servers or references to said executable code.

3. A method of distributing the load within a plurality of servers (S₁, S₂, S₃) connected to a network (N) and implementing a service, which method is characterized in that it includes a step of transmitting data packets containing or referring to executable code (c₁, c₂, C₃) adapted to be executed by equipment (E₁, E₂, E₃) of said network and to distribute service requests among said plurality of servers.

4. A method according to the preceding claim, wherein said plurality of servers is divided into a plurality of groups and each group is connected to a different equipment of said network.
