Internet Traffic Models: Features
LAN connections differ from WAN connections
- higher bandwidth (more bytes/call)
- longer holding times (free and higher bandwidth!)
Many parameters are heavy-tailed
- e.g. number of bytes in call, call duration
- means a few calls are responsible for most of the traffic
- these calls must be well managed
- also means that even aggregates with many calls are not smooth (self-similar or LRD traffic)
New models appear all the time, to account for rapidly changing traffic mix
