* Hashing.
|
|
*
|
|
* The server uses a chained hash table to provide quick and efficient
|
|
* hash table maintenance (providing the hash function works evenly over
|
|
* the input range). The hash table is thus not susceptible to problems
|
|
* of filling all the buckets or the need to rehash.
|
|
* It is expected that the hash table would look something like this
|
|
* during use:
|
|
* +-----+ +-----+ +-----+ +-----+
|
|
* ---| 224 |----| 225 |----| 226 |---| 227 |---
|
|
* +-----+ +-----+ +-----+ +-----+
|
|
* | | |
|
|
* +-----+ +-----+ +-----+
|
|
* | A | | C | | D |
|
|
* +-----+ +-----+ +-----+
|
|
* |
|
|
* +-----+
|
|
* | B |
|
|
* +-----+
|
|
*
|
|
* A - GOPbot, B - chang, C - hanuaway, D - *.mu.OZ.AU
|
|
*
|
|
* The order shown above is just one instant of the server.
|
|
*
|
|
*
|
|
* The hash functions currently used are based Fowler/Noll/Vo hashes
|
|
* which work amazingly well and have a extremely low collision rate
|
|
* For more info see http://www.isthe.com/chongo/tech/comp/fnv/index.html
