Abstract
A method and apparatus for parameter borrowing for network address translator (NAT) configuration by receiving, at a first dynamic host configuration protocol (DHCP) device, a DHCP lease request from a client, determining, from the DHCP lease request, first communication parameters of the client, and enabling the determined first communication parameters to be used by a second DHCP device, the determined first communication parameters adapted for use in upstream DHCP lease requests by the second DHCP device.
Claims19
A method, comprising:
- receiving, at a first dynamic host configuration protocol (DHCP) device, a DHCP lease request from a client;
- determining, from the DHCP lease request, first communication parameters of said client;
- and
- enabling said determined first communication parameters to be used by a second DHCP device, said determined first communication parameters adapted for use in upstream DHCP lease requests by said second DHCP device.
9 An apparatus, comprising:
- a first dynamic host configuration protocol (DHCP) device, for receiving DHCP lease requests from a client;
- a second DHCP device, for generating upstream DHCP lease requests;
- a memory for storing communications parameters and instructions;
- and
- a processor, upon executing said instructions, configured to:
- receive at said first DHCP device, a DHCP lease request from said client;
- determine, from the DHCP lease request, first communication parameters of said client;
- and
- enable said determined first communication parameters to be used by a second DHCP device, said determined first communication parameters adapted for use in upstream DHCP lease requests by said second DHCP device.
The apparatus of claim 9, wherein said processor, upon executing said instructions, is further configured to:
- determine, from a DHCP lease grant sent in response to said upstream DHCP lease request by said second DHCP device, second communications parameters;
- and
- enable said determined second communication parameters to be used by said first DHCP device.
The apparatus of claim 9, wherein said first DHCP device comprises a DHCP server.
The apparatus of claim 9, wherein said second DHCP device comprises a DHCP client.
The apparatus of claim 9, wherein said apparatus is incorporated into an edge networking device.
Computer-readable medium for storing a set of instructions, wherein when said set of instructions is executed by a processor performs a method comprising:
- receiving, at a first dynamic host configuration protocol (DHCP) device, a DHCP lease request from a client;
- determining, from said DHCP lease request, first communication parameters of said client;
- and
- enabling said determined first communication parameters to be used by a second DHCP device, said determined first communication parameters adapted for use in upstream DHCP lease requests by said second DHCP device.
A method for self-configuration of a NAT device, comprising:
- receiving, at a first dynamic host configuration protocol (DHCP) device, a DHCP lease request from a client;
- determining, from the DHCP lease request, first communication parameters of said client (110);
- enabling said determined first communication parameters to be used by a second DHCP device, said determined first communication parameters adapted for use in upstream DHCP lease requests by said second DHCP device;
- determining, from a DHCP lease grant sent in response to said upstream DHCP lease request by said second DHCP device, second communications parameters;
- and
- enabling said determined second communication parameters to be used by said first DHCP device.
A communication network, comprising:
- a local area network (LAN);
- a wide area network (WAN);
- a network address translator (NAT), comprising,
- a first dynamic host configuration protocol (DHCP) device, for receiving DHCP lease requests from said LAN;
- a second DHCP device, for generating upstream DHCP lease requests to said WAN;
- a memory for storing communications parameters and instructions;
- and
- a processor, upon executing said instructions, configured to:
- receive at said first DHCP device, a DHCP lease request from said LAN;
- determine, from the DHCP lease request, first communication parameters of said LAN;
- and
- enable said determined first communication parameters to be used by a second DHCP device, said determined first communication parameters adapted for use in upstream DHCP lease requests by said second DHCP device to said WAN.
An apparatus, comprising:
- means for receiving, at a first dynamic host configuration protocol (DHCP) device, a DHCP lease request from a client;
- means for determining, from the DHCP lease request, first communication parameters of said client;
- and
- means for enabling said determined first communication parameters to be used by a second DHCP device, said determined first communication parameters adapted for use in upstream DHCP lease requests by said second DHCP device.
