摘要: Load balancing is a key technique for improving Internet performance. Effective use of load requires good traffic distribution schemes. We study the performance several hashing schemes distributing over multiple links while preserving order packets within flow. Although hashing-based have been proposed in past, this first comprehensive their using real traces. evaluate five direct methods and one table-based method. find that 16-bit CRC five-tuple gives excellent Further, load-adaptive exclusive OR source destination IP addresses achieves comparable to CRC. Table-based can also distribute according unequal weights. report on four other with poor moderate
