Abstract
Description
technical field
[0001] The present invention relates generally to communication devices, and more particularly to generating communication traffic control rules for communication devices. Background technique
[0002] An Access Control List (ACL, Access Control List) is widely used in communication devices to filter Internet Protocol (IP) services. ACLs include a list of rules that are applied to packets based on fields in the packet header, such as source address, destination address, protocol ID, port ID, and the like. ACLs are typically applied in the data path of line cards that provide the interface between a communication device and the communication medium, and can be implemented in hardware for relatively simple rules, or implemented in hardware for more complex rules. implemented in software. ACLs may also be applied at the control card for traffic terminated at the communication device.
[0003] Various configuration settings may also be established for communic...

Embodiment Construction
[0021] figure 1 is a flowchart illustrating a method according to an embodiment of the invention for automatically creating traffic control rules, illustratively ACLs, from configuration information associated with a communication device. In a preferred embodiment, the method is machine implemented so that the ACL is automatically generated without manual input from the user.
[0022] The method begins at 10 with an operation of accessing configuration information of the communication device. At 12, one or more parameters affecting processing of communication services by the communication device are determined according to the configuration information. At 14, one or more traffic control rules are established based on the parameters determined at 12.
[0023] As will be apparent to those skilled in the art, any traffic control rules established at 14 establish the conditions under which traffic is controlled at the communication device. For example, an ACL controls traffic ...
