Abstract
Abstract A method and apparatus for interconnecting a first device and a second device in a network. The first device and the second device are connected to a plurality of interfaces. The plurality of interfaces emulate a single high-speed interface. According to an embodiment of the present invention, a first identifier is assigned to the first interface and the second interface at the first device. According to another embodiment of the present invention, one of the plurality of interfaces is selected to transmit a packet of data. <IMAGE>
