Detailed Description
- Parameter Description
- Quantum: Number of bytes to send out per slot and round.
- Perturbation: Timer period between changing the hash function.
- Limit: Upper limit of queue in number of packets before SFQ starts dropping packets.
- Divisor: Hash table divisor, i.e. size of hash table.
