Systems and methods for address translation in switch apparatuses

A switch apparatus comprising:

• a first port configured to receive a first request associated with a first address;
• a cache configured to store a plurality of mapping entries;
• a routing unit coupled to the cache, the routing unit being configured to:
• determine a presence or an absence of a second address in the plurality of mapping entries, the second address being associated with the first address;
• in response to a determination of the presence of the second address in the plurality of mapping entries, retrieve the second address;
• and
• in response to a determination of the absence of the second address in the plurality of mapping entries, forward the first request to a first device to obtain the second address;
• and
• a second port coupled to the routing unit, the second port being configured to transmit the first request based on the second address;
• wherein the routing unit is configured to update the cache with a first mapping entry associating the first address with the second address obtained from the first device.

A switch apparatus comprising:

• a first port configured to receive a first request associated with a first address;
• a cache configured to store a plurality of mapping entries, the plurality of mapping entries comprising a first mapping entry associating the first address with a second address;
• a controller coupled to the cache, the controller being configured to manage the plurality of mapping entries stored in the cache based on a predetermined criterion;
• a routing unit coupled to the cache, the routing unit being configured to determine a destination for the first request based on the second address;
• and
• a second port coupled to the routing unit, the second port being configured to transmit the first request to the destination.
