Twin-wavelength ring optical network for computer cluster

It is well known that a wavelength can be regarded as an address code of a packet in the optical interconnection network. In our scheme, we use wavelength as a part of an address to build a multiple wavelengths optical interconnection ring network. The network consists of double layer rings, the routing inside a ring is electronic, and wavelength routing technology is applied to switch between rings. Two wavelength are used in the network, one is for transmitting data inside local ring, another is for switching to another ring. The detail of the network is described in this paper. Besides, a low-cost virtual parallel optical link and optical interconnection interface, which is bound up with the multiple-wavelengths network, is presented.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
