The fibre channel frame includes time stamp information associated with fibre channel switches between a second fibre channel switch and the first fibre channel switch. A time-to-live (TTL) value included in the fibre channel frame is determined. The fibre channel frame is sent back to the second fibre channel switch upon determining the TTL value included in the fibre channel frame.
12. The apparatus of claim 11, wherein the fibre channel frame is sent back to the source fibre channel switch when the TTL value is determined to be 1.
13. The apparatus of claim 11, wherein the fibre channel frame includes a loop back field indicating that the fibre channel frame should be looped back when the TTL value reaches 1.
CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 10/170,855 filed Jun. 12, 2002 by Maurilio Cometto and Thomas Edsall, now U.S. Pat. No. 7,206,288 and titled �METHODS AND APPARATUS FOR CHARACTERIZING A ROUTE IN A FIBRE CHANNEL FABRIC,� which is incorporated herein by reference in its entirety and for all purposes.
TECHNICAL FIELD The present disclosure relates to determining route characteristics in fibre channel networks
DESCRIPTION OF RELATED ART Techniques and mechanisms for determining route characteristics in fibre channel network are limited. Many fibre channel networks lack efficient mechanisms for performing functions such as determining connectivity to a destination, understanding the path followed by a specific data flow, evaluating the latency of each hop, tracing a route, etc.
