Abstract
Method and system for processing frames in a fibre channel network is provided. The method includes, determining if an incoming frame in a port of a fibre channel switch includes a FR_Header with a time to live time ('TTLT') field value; determining if the TTLT field value is greater than a certain number; adjusting the TTLT field value at a pre-determined time interval if the TTLT field value is greater than the certain number; and inserting an adjusted TTLT field value in the incoming frame before it is sent out. The switch element includes, a port that receives an incoming frame and determines if a FR_Header with a time to live time ('TTLT') field value is received with the FR_Header, and using a timer adjusts the TTLT field value and inserts the adjusted TTLT field value in the incoming frame, before it is sent out.
