An upstream line card including a digital or analog multiplexer front end circuit for a Cable Modem Termination System. Each upstream line card has only upstream receivers and allows a CMTS to share one or a handful of receiver chips to receive and recover data from a larger number of input cables coupled to the front end multiplexer. A control circuit for the multiplexer uses MAP data and burst assignment data and upstream mini-slot counts for each of the input cables to determine when a burst is about to arrive on a cable and cause appropriate switching by the multiplexer or crossbar switch. In some embodiments, there is only one RF channel circuit coupled to the output of the multiplexer, so the multiplexer is controlled to couple the input cable upon which the burst is expected to the single RF channel. In other embodiments, there are multiple RF channels coupled to the inputs of the multiplexer so the multiplexer is controlled to connect each input cable on which a burst is expected to an available RF channel. In some embodiments, the sample data generated by each RF channel is buffered and an arbiter picks one burst at a time for application to the input of a CMTS receiver or doles out bursts to different receivers. In other embodiments, no buffers or arbiter are used, and each RF channel has its own dedicated CMTS receiver.

This invention is to enable appropriate routing based on transition prediction of network traffic. This routing control method includes: reading out predicted utilization transition data (e.g. utilization rate, or utilized bandwidth) associated with a received connection set-up request from a predicted utilization transition data storage storing said predicted utilization transition data for each resource (e.g. links between routers, or server) in a network in future; and selecting a resource satisfying a predetermined condition based on the read predicted utilization transition data. Thus, by using said predicted utilization transition data, an appropriate resource is identified in accordance with future time transition of the resource utilization rate, for example, and thereby, appropriate routing is possible. For example, when a link that a traffic volume will increase after a predetermined time exists, it is possible to judge that such a link is not used even when there are a lot of available bandwidths now.

Ethanol and other liquid products are produced by contacting syngas components such as CO or a mixture of CO2 and H2 with a surface of a membrane under anaerobic conditions and transferring these components in contact with a biofilm on the opposite side of the membrane. These steps provide a stable system for producing liquid products such as ethanol, butanol and other chemicals.

The present invention relates to a method for preparing, from wood-based biomass, a high concentration of fermentable sugar which can be effectively used in culturing various industrial fermented bacteria. According to the method of the present invention, biomass can be extracted by hot water prior to a pre-treatment so as to remove extractible substances such as mineral salts to thus minimize the content of impurities in raw materials for an enzymatic saccharification.
