Abstract

A first computational device receives a response generated by a second computational device for a third computational device. A target that is suitable for use by the third computational device is determined. The response is transmitted with an address of the target to the third computational device.

Claims

1. A method, comprising:

receiving, via a first computational device, a response generated by a second computational device for a third computational device;

determining a target that is suitable for use by the third computational device; and

transmitting the response with an address of the target to the third computational device.

2. The method of claim 1, wherein suitability of the target for use by the third computational device is based on at least a distance of the target from the third computational device, an available bandwidth, and a processing load on the target.

3. The method of claim 1, wherein the target that is determined has a relatively light processing load and is relatively more proximate to the third computational device in comparison to other potential targets of a plurality of targets.

4. The method of claim 1, wherein:

the first computational device is a control plane processor;

the second computational device is a Dynamic Host Configuration Protocol (DHCP) server; and

the third computational device is an initiator.

5. The method of claim 4, the method further comprising:

transmitting, by the initiator, via a switch configuration that includes one or more switches, a request for a DHCP address to the DHCP server; and

transmitting, by the DHCP server via the switch configuration, the response comprising the DHCP address.

6. The method of claim 5, the method further comprising:

redirecting, by the one or more switches the response to the control plane processor instead of returning the response to the initiator.

7. The method of claim 6, wherein the address of the target is added to the response by modifying a DHCP Option 17 command.

8. A system, comprising a first computational device that is communicatively coupled to a second computational device and a third computational device, wherein the system comprises:
