FLOW MATCHING OPTIMIZATION IN SCALED ENVIRONMENTS |
| 摘要 |
In one embodiment, a method includes identifying at a network device, a number of items for matching at a hash table, the number of items exceeding matching available with ternary content addressable memory (TCAM) at the network device, defining at the network device, an optimal cyclic redundancy check (CRC) polynomial based on the number of items for matching at the hash table, and generating at the network device, an optimal hash function based on the optimal CRC polynomial to extend packet classification capability at the network device. An apparatus is also disclosed herein. |

1. A method comprising:
identifying at a network device, a number of items for matching at a hash table, the number of items exceeding matching available with ternary content addressable memory (TCAM) at the network device; defining at the network device, an optimal cyclic redundancy check (CRC) polynomial based on the number of items for matching at the hash table; and generating at the network device, an optimal hash function based on said optimal CRC polynomial to extend packet classification capability at the network device. |
