Abstract
There is described a method of managing a flow of data packets in a multiple-processing entity system comprising a plurality of look-up tables adapted to store information associated to actions to be performed on packets received by the system. The method comprises storing, on a per entry basis, in a shadowed entry associated to any table entry being updated, the previous content of said table entry being updated, in association with a table entry version number, for use for managing packets received in the system prior to any update operation. It is thus possible to continue using look-up tables while updating process is being carried out for some or all of the table entries. The solution provides benefits for systems that are limited in space and cost, by use of minimal memory thanks to the storing of small shadowed data instead of full shadowed table.
