<p>A packet carried on an optical network is routed by carrying out a logic operation on an address word carried in a packet header, and a predetermined discriminator word. A binary routing decision is made in accordance with the product of the logic operation. The operation may be a bit-wise Boolean AND operation. An additional logic operation may be carried out with an additional discriminator word to determine whether the packet is destined for a remoter region of the network. In this case the packet may be steered directly to the remote region.</p> |
