In multi-site systems, when a site goes down (e.g., due to failure), those radios affiliated with the site re-affiliate with a neighboring site. Because all the radios affiliated with the failed site will attempt to re-affiliate with a neighboring site at about the same time, the neighboring sites may become flood- ed and the system may become unusable. A typical system can affdiate about two users per second, and if a large site is involved, thousands of users may need to re-affiliate. Consequently, it will take a long time to re-affiliate some users, and in the mean time, no one can use the system until the re-afftlia- tions are all handled. A similar problem results when a normally heavily-loaded site comes back on line, and users try to re-affiliate with the site due to site preferences, available resources, etc.
