Abstract
Software tables are much faster to be updated than hardware ones A hybrid architecture can exploit the following logic: • Forwarding tables updates always happen in software first • Entries are eventually moved to the hardware forwarding tables, offloading the Software forwarder Overlapping entries may break the forwarding decisions in respect to their priorities Deleting entries from hardware tables is usually much faster than adding them: • Installation in hardware tables may require a reorganization of the previously installed Flow Table Entries A hybrid architecture can translate an entry installation into a mix of installation in software tables and deletion from hardware tables
