Definitions

  • This invention relates to a networking addressing system which provides logical addresses to network devices based on the port of a network switch to which the network device is connected.
  • MAC Media Access Control
  • IP Internet Protocol
  • Every network device 4 has a different MAC address 2, when one network device 4 is unplugged from the network and another network device 4 put in its place, a subsequently connected network device in the same location as the first network device 4 will most likely not be assigned the same IP address 6 as the first. This is especially true in systems where IP addresses 6 are
  • IP address 6 is reserved. This method of assigning IP addresses is desirable where network devices move from place to place but wish to maintain their original logical identity on the network or when a particular location on the network is used by many different network devices at different times, such as in an office environment.
  • a network management professional must be summoned to perform the task of associating the IP address with the new MAC address, and, as a result, the machine must left offline until a networking professional can be summoned.
  • This loss of machine production time costs a significant loss in production and, therefore, money.
  • This invention eliminates the need for the network management professional to be available for replacement of the network device. The present invention solves this and other problems.
  • the present invention discloses a network switch for a computer network which receives a network message from a network device and forwards the network message to an appropriate destination.
  • the network switch has a plurality of ports for receiving and forwarding the network message.
  • the network switch has a logical address server which assigns a logical address to a network device based upon the port of the network switch to which the network device is connected.
  • a logical address server connectable to the port of a network switch.
  • the logical address server assigns logical addresses to network devices connected to the network switch.
  • the logical address server assigns a logical address to a network device based upon the port of the network switch to which the network device is connected.
  • a method of assigning a logical address to network device connected to a port of a network switch comprising the step of assigning the logical address based upon the port of the network switch to which the network device is connected and a device for performing the method.
  • FIG. 1 is a diagram of a system of assigning logical addresses according to the prior art.
  • FIG. 2 is a diagram of a system of assigning logical addresses according to an embodiment of the present invention.
  • FIG. 3 is a diagram of a system of assigning logical addresses according to a second embodiment of the present invention.
  • FIG. 2 there is shown a computer network switch 10 having six ports 12. It should be understood and will be readily apparent to one of ordinary skill in the art that the network switch could have any number of ports 12.
  • the network devices 14 can be any electrical device capable of communication over a computer network, such as a personal computer, a programmable logic controller or an input/output device.
  • the network switch 10 receives a network message from any one of the network devices 14 and forwards the network message to an appropriate destination.
  • the appropriate destination depends on the type of network being used.
  • the network switch could be a "smart" network switch and forward the network message to one or more network devices 14 for which the network message is intended, or it could be a "dumb” network switch and forward the message to all network devices 14.
  • the network devices 14 for which the network message is not intended merely ignore the network message.
  • the network switch might merely pass the network message to the next computer in the ring. All of the scenarios for an appropriate destination are well known and are readily understood by one of ordinary skill.
  • the network switch 10 further comprises a logical address server 18 which assigns an IP address 16 to a network device 14 based upon the port
  • the logical address server 18 In order for the logical address server 18 to know which IP address 16 to assign each port 12, the logical address server 18 must be initially configured by a networking professional to associate each IP address 16 with each port 12. In use, when one of the network devices 14 fails, a technician simply removes the defective network device 14 from the network by disconnecting it from the port 12. A new network device 14 is then placed on the network by connecting it to the port 12 from which the failed network device 14 was disconnected. Either upon connecting the new network device 14 to the network or upon the network device's 14 request, an IP address 16 is assigned by the logical address server 18 to the new network device 14 based on the port 12 of the network switch to which the device is connected. In this manner, the failed network device 14 and the new network device 14 have the same IP address 16.
  • the logical address server 18 can be configurable to assign an IP address 16 based on either the port 12 of the network switch 10 or assign an IP address 16 based upon a MAC address associated with the network device 14.
  • the network switch 10 is preferably connected to network devices 14 by electrical wires and the network messages are preferably electrical signals.
  • the present invention can be easily adapted to accept fiber optical cables to connect the network devices to the network switch which transmit light pulses as the network messages.
