METHOD FOR DETERMINING STORAGE LOCATION FOR TABLES, FORWARDING DEVICE, AND CONTROLLER

摘要

Embodiments of the present invention provide a method for determining a storage location for tables. The method comprises: a forwarding device receives M pieces of description information that are sent by a controller and are in a one-to-one correspondence with M forwarding services, each piece of description information comprising predetermined performance of the corresponding forwarding service and an identifier of a table to be searched; a set formed of the predetermined performance of the M forwarding services comprises Q elements; the forwarding device generates Q pieces of simultaneous access information according to the M pieces of description information; and the forwarding device determines, according to the Q pieces of simultaneous access information, that N tables are to be stored in at least one memory of the forwarding device. In addition, other methods and devices are also provided. Simultaneous access information of tables to be searched for executing forwarding services is generated by means of the description information of the forwarding services, and it is further determined that the tables are to be stored in at least one memory of a forwarding device, thus enabling actual performance of the forwarding services to reach predetermined performance as far as possible.
