Methods and apparatus for performing continue actions using an associative memory which might be particularly useful for implementing access control list and quality of service features

A computer-readable medium including computer-executable instructions for performing steps for use with an associative memory, said steps comprising:

• identifying a merged element based on a first element and a second element, the first element having first element indications associated therewith, said first element indications including a first operation, a first action, and a first continue indication, and the second element having second element indications associated therewith, said second element indications including a second operation and a second action;
• determining that the first continue indication corresponds to performing a continue action and the second operation corresponds to permit;
• and
• in response to said determining that the first continue indication corresponds to performing a continue action and the second operation corresponds to permit, causing programming of the associative memory to include a first entry and a second entry, the first entry including the merged element and a first entry continue level, the second entry including the merged element and a second entry continue level, the second entry continue level being the next in a continue series after the first entry continue level.

An apparatus for use with an associative memory, the apparatus comprising:

• means for identifying a merged element based on a first element and a second element, the first element having first element indications associated therewith, said first element indications including a first operation, a first action, and a first continue indication, and the second element having second element indications associated therewith, said second element indications including a second operation and a second action;
• means for determining that the first continue indication corresponds to performing a continue action and the second operation corresponds to permit;
• and
• means for causing programming of the associative memory, in response to said determining that the first continue indication corresponds to performing a continue action and the second operation corresponds to permit, to include a first entry and a second entry, the first entry including the merged element and a first entry continue level, the second entry including the merged element and a second entry continue level, the second entry continue level being the next in a continue series after the first entry continue level.

A method for use with an associative memory, the method comprising:

• identifying a merged element based on a first element and a second element, the first element having first element indications associated therewith, said first element indications including a first operation, a first action, and a first continue indication, and the second element having second element indications associated therewith, said second element indications including a second operation and a second action;
• generating one or more associative memory entries and one or more adjunct memory entries, each of said one or more associative memory entries having a corresponding one of said one or more adjunct memory entries, said one or more associative memory entries including a first associative memory entry, said one or more adjunct memory entries including a first adjunct memory entry, the first adjunct memory entry corresponding to the first associative memory entry, the first associative memory entry including the merged element, and the first adjunct memory entry including a first action value;
• wherein, when the first operation does not correspond to permit, then the first action value corresponds to the second action;
• wherein when the first operation corresponds to permit and the first continue indication does not correspond to perform a continue operation, then the first action value corresponds to the first action;
• wherein when the first operation corresponds to permit, the first continue indication corresponds to perform a continue operation, and the second operation does not correspond to permit, then the first action value corresponds to the first action;
• and
• wherein when the first operation corresponds to permit, the first continue indication corresponds to perform a continue operation, and the second operation corresponds to permit, then the first action value corresponds to the first action and the first entry includes a continue level having a first value, and said one or more associative memory entries includes a second associative memory entry, said one or more adjunct memory entries includes a second adjunct memory entry, the second adjunct memory entry corresponding to the second associative memory entry, the second associative memory entry including the merged element and a continuation level having a value after said first value in a predetermined continue level sequence, and the second adjunct memory entry including a second action value corresponding to the second action.

• wherein, when the first operation does not correspond to permit, then the first action value corresponds to the second action;
• wherein when the first operation corresponds to permit and the first continue indication does not correspond to perform a continue operation, then the first action value corresponds to the first action;
• wherein when the first operation corresponds to permit, the first continue indication corresponds to perform a continue operation, and the second operation does not correspond to permit, then the first action value corresponds to the first action;
• and
• wherein when the first operation corresponds to permit, the first continue indication corresponds to perform a continue operation, and the second operation corresponds to permit, then the first action value corresponds to the first action and the first entry includes a continue level having a first value, and said one or more associative memory entries includes a second associative memory entry, said one or more adjunct memory entries includes a second adjunct memory entry, the second adjunct memory entry corresponding to the second associative memory entry, the second associative memory entry including the merged element and a continuation level having a value after said first value in a predetermined continue level sequence, and the second adjunct memory entry including a second action value corresponding to the second action.
