Methods and apparatus for randomly distributing traffic in a multi-path switch fabric
摘要
說明書
In some embodiments, data can be routed through the switch fabric 200 using hash functions, lookup tables, routing tables and/or the like. For example, a first stage switch module 212 can determine to which second stage switch module 214 to send a data cell by using header values of the data cell as inputs to a hash function. A result of the hash function can be an identifier of a second stage switch module 214 and the first stage switch module 212 can send the data cell accordingly. Similarly, a second stage switch module 214 and/or a third stage switch module 216 can determine to which third stage switch module 216 or to which edge device (i.e., coupled to an egress port 262), respectively, to send the data cell, respectively, using such a hash function, a lookup table and/or a routing table.
