Method and apparatus for handling address resolution protocol requests for a device having multiple interfaces
First Claim
1. A method, comprising:
- receiving a message transmitted by a remote device to a host, wherein the message includes a request to provide a value representative of an address associated with the host and wherein the message includes a value representative of an address associated with the remote device;
comparing at least a portion of the value representative of the address associated with the remote device to a value stored in an address field on a storage unit; and
discarding the message in response to determining that at least the portion of the value representative of the address associated with the remote device is substantially equal to the value stored in the address field.

Abstract
The present invention provides a method and apparatus for handling address resolution protocol requests for a device having multiple interfaces. The method comprises receiving a message transmitted by a remote device to a host. The message includes a request to provide a value representative of an address associated with the host and the message includes a value representative of an address associated with the remote device. The method further comprises comparing at least a portion of the value representative of the address associated with the remote device to a value stored in an address field on a storage unit and discarding the message in response to determining that at least the portion of the value representative of the address associated with the remote device is substantially equal to the value stored in the address field.

8. An article comprising one or more machine-readable storage media containing instructions that when executed enable a processor to:
-
receive a message transmitted by a remote device over a first interface of a host, wherein the message includes a request to provide an address associated with the host and wherein the message includes an address associated with the remote device;
receive the message over a second interface of the host;
compare the address associated with the remote device to a value stored in an address field on a storage unit;
store the address associated with the remote device in the address field in response to determining that the address associated with the remote device is not substantially equal to the value stored in the address field; and
transmit a response to the remote device in response to determining that the address associated with the remote device is not substantially equal to the value stored in the address field, wherein the response includes the address associated with the host. - View Dependent Claims (9, 10, 11, 12, 13)

14. An apparatus, comprising:
-
at least a first interface and a second interface; and
a control unit adapted to;
receive a message transmitted by a remote device to a host, wherein the message includes a request to provide a value representative of an address associated with the host and wherein the message includes a value representative of an address associated with the remote device;
compare at least a portion of the value representative of the address associated with the remote device to a value stored in an address field on a storage unit; and
discard the message in response to determining that at least the portion of the value representative of the address associated with the remote device is substantially equal to the value stored in the address field. - View Dependent Claims (15, 16, 17, 18, 19, 20)
