Abstract

A method and apparatus for dynamically and automatically configuring an endpoint device to a computer network of a network system. When the endpoint device, such as a computer or router, initially connects to a computer network, it is dynamically assigned or allocated a first unique network (IP) address, as by a DHCP (Dynamic Host Configuration Protocol) server. The allocation of the first network address is monitored and, in response to the monitored allocation, a connection between a configuration manager and the endpoint device is established. The class of the endpoint device is then remotely identified and appropriate configuration information stored in a configuration database is retrieved and utilized to automatically configure the endpoint device within the network system.

Claims

storing configuration information in a configuration database, the configuration information comprising one set of configuration information for each class of the plurality of classes of endpoint devices, such that each class associated with a different variety of endpoint device and each one set of configuration information is applicable to all endpoint devices in the each class;

monitoring a dynamic allocation of a first unique network address to the endpoint device when the endpoint device is connected to the computer network;

establishing, in response to said monitoring, a connection between a configuration manager and the endpoint device;

identifying, through said established connection, a class of the endpoint device connected to the network from said plurality of classes of endpoint devices;

retrieving the set of configuration information from the configuration database that is associated with the identified class of the endpoint device; and

configuring the endpoint device to the computer network using the retrieved configuration information.

2. The method according to claim 1, further comprising the step of:

assigning to the endpoint device a second unique network address that is selected from a block of predetermined network addresses for the identified class of the endpoint device, to replace the first unique network address.

3. The method according to claim 2, wherein the first unique network address is a first IP address allocated by a DHCP (Dynamic Host Configuration Protocol) server and the second unique network address is a second IP address assigned by the configuration manager.

4. The method according to claim 1, further comprising the steps of:

receiving, by the computer network from the endpoint device, a request signal for assignment of a network address to the endpoint device; and

providing the first unique network address to the endpoint device in response to said request signal.

5. The method according to claim 1, further comprising the steps of:

transmitting a polling signal to the endpoint device when the endpoint device is connected to the network;

receiving from the endpoint device a reply signal in response to the transmitted polling signal; and

providing the first unique network address to the endpoint device in response to said reply signal.

6. The method according to claim 1, wherein the endpoint device comprises a router operatively connected to a second computer network for effecting a configuration of a plurality of computer networks.
