Method and system for speed negotiation for twisted pair links using intelligent E-FIFO in fibre channel systems

摘要

Certain aspects of a method and system for speed negotiation for twisted pair links using intelligent elastic first-in-first-out (E-FIFO) in fiber channel systems are disclosed. Aspects of a method may include determination of a priority level based on amount of data in at least one elastic FIFO (E-FIFO) buffer communicatively coupled to at least one of the fiber channel host devices. The E-FIFO buffer may be modified either by insertion or deletion of IDLE words or words from an order set based on the determined priority level. The data may be synchronously communicated between fiber channel host devices communicatively coupled via the twisted pair link based on the modified elastic buffer.
