application_number US 10639605 A description fig1 shows a block diagram of a typical distributed directory network in accordance with an illustrative embodiment of the present invention a first backend directory server 103 supports a portion of the overall directory of the domain the workload is shared with a second backend directory server 105 each backend directory server may be simply referred to as a backend the combined backends may present themselves to the network as if they were a single device with for example a common internet protocol ip address this is ordinarily accomplished through the use of a proxy server 101 which may provide security and load sharing functions queries for directory service may arrive to the domain through a network connection 109 that may connect with among other things the internet 111 frequently such distributed directory networks are established with more than two backend servers with reference now to fig2 a block diagram illustrating a data processing system is depicted in which the present invention may be implemented data processing system 200 is an example of a computer which may operate in the capacity of a backend distributed directory server a single directory server or a proxy server data processing system 200 employs a peripheral component interconnect pci local bus architecture although the depicted example employs a pci bus other bus architectures such as accelerated graphics port agp and industry standard architecture isa may be used processor 202 and main memory 204 are connected to pci local bus 206 through pci bridge 208 pci bridge 208 also may include an integrated memory controller and cache memory for processor 202 additional connections to pci local bus 206 may be made through direct.
