In a communication network system having a multi-switch Fiber Channel
fabric, adjacent switches are communicatively coupled together by a
plurality of links. The links are selectively determined to join a
trunked group for enabling frames received at one switch to be routed
over the links in the trunked group to the adjacent switch in an evenly
distributed manner. In one embodiment, a link within the trunked group is
coupled to a pair of ports residing on adjacent switches each having a
designated trunking master port. The traffic load at one switch is routed
through the trunking master port which distributes the load across
multiple links and guarantees that the load is received at the adjacent
switch with "in-order" delivery.
