Abstract
Abstract A packet control list (456) controls the transfer of data packets between at least one source location (452) and at least one destination location (460) each associated with a data packet transfer device (20). Packet control list (456) associates a plurality of data packet transfer control instructions (454) in a sequential list (466) including a plurality of logical functions (472) for controlling logical operations relating to the transfer of data packets from at least one source location (452) to at least one destination location (460). Instructions (486) control the operation of data packet transfer device (20) according to instructions (486).

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
106 words
A method for controlling transfer of data packets between at least one source location and at least one destination location each associated with the data packet transfer device, the method comprising the steps associating a plurality data packet transfer control instructions in a packet control list, said packet control list comprising a plurality of logical functions for controlling logical operations relating to the transfer of data packets from said at least one source location to said at least one destination location; and controlling the operation of the data packet transfer device according to the plurality of data packet transfer control instructions on said packet control list.
Claim 2
Independent Claim
106 words
A method for controlling transfer of data packets between at least one source location and at least one destination location each associated with the data packet transfer device, the method comprising the steps associating a plurality data packet transfer control instructions in a packet control list, said packet control list comprising a plurality of logical functions for controlling logical operations relating to the transfer of data packets from said at least one source location to said at least one destination location; and controlling the operation of the data packet transfer device according to the plurality of data packet transfer control instructions on said packet control list.
Claim 3
Dependent Claim
21 words
The method of claim 1, further comprising the step of associating an auxiliary packet control command in said packet control list.
Claim 4
Dependent Claim
27 words
The method of claim 1, further comprising the step of storing both a plurality of receive and a plurality of transmit commands in said packet control list.
Claim 5
Dependent Claim
27 words
The method of claim 1, further comprising the step of associating a plurality of receive commands and a plurality of auxiliary commands in said packet control list.
Claim 6
Dependent Claim
19 words
The method of claim 1, further comprising the step of linking together a plurality of said packet control lists.
Claim 7
Dependent Claim
26 words
