Abstract:
1. A security system in a communication system including an IP network and a plurality of groups of servers in a server farm, each of said groups being associated with a customer, and wherein a user connected to said IP network can access information provided by a customer from a server within the group of servers associated with said customers through a dispatching device adapted to select a server amongst the servers of said group of servers according to a predefined algorithm, said dispatching device being connected to the servers through switches adapted to control the data transmission exchanged between said dispatching device and said servers, said security system comprising: setting means in each one of said switches for setting, to a predefined value, a field of bits in an IP header of a potentially irregular packet transmitted from a customer server; identifying means in said dispatching device for identifying any packet wherein said field of bits has been set to said predefined value; relaying means for relaying a packet from a server in the server farm to a user via the Internet in the case that the packet is not identified as a potentially irregular packet; and disposing means for disposing said potentially irregular packet as being an irregular packet because the destination of such a packet is a server in the server farm.
