| 1. A method of transmitting a sequence of cells from a first network device to a second network device, said first network
device comprising a plurality of port interfaces, each of said plurality of port interfaces being coupled to a corresponding
port interface on said second network device by a corresponding communication path, said method being performed in said first
network device, said method comprising:
maintaining a group information indicating that a first port interface and a second port interface are comprised in a cluster
interface, said first port interface and said second port interface being comprised in said plurality of port interfaces;
sending a first plurality of cells on a virtual circuit assigned to said first port interface, wherein said first plurality
of cells are comprised in said sequence of cells;
examining said group information to determine that said virtual circuit can be moved to said second port interface, wherein
said moving is performed based on said examining,
moving said virtual circuit from said first port interface to said second port interface based on said examining; and
sending a second plurality of cells on said virtual circuit moved to said second port interface, wherein said second plurality
of cells are also comprised in said sequence of cells.
