摘要： A Control Unit is described, including a Processing Unit (12) controlled by a Service Processor (14), and a plurality of adapters (18) exchanging data and/or control signals with said Processing Unit (PU). For ensuring a continuous operation of the Control Unit, the adapters are partitioned into at least two sets (56,58), and the PU is partitioned into at least two parts (26,28), each set of adapters being connected to a dedicated PU part by a primary bus (52,54). Besides, in order to allow the fallback of a set of adapters onto another PU part if the PU part to which it is normally connected is inoperative, a bus switching device (30) is provided. This bus switching device includes at least two Switch parts (38,40), and each Switch part performs the switching of a given set of adapters onto a given PU part, according to the status of each PU part. Therefore, each Switch part is connected to a given set of adapters by a primary bus (52,54), and to the other sets of adapters by secondary busses (46,48) which become active in fallback mode.

摘要： The present invention relates to an efficient point-to-point and multi-points routing system and method for programmable data communication adapters in packet switching nodes of high speed networks. The general principles of this efficiency are the following:First, data packets are never copied, only packet pointers are copied for each destination: Space in Buffer Memory is saved, the number of instructions is significantly reduced improving the packet throughput (number of packets per seconds that the adapter is able to transmit). and the routing is independant of the packets length.Second, no overhead is generated by the multi-points mechanism in the real time procedures: the underrun/overrun problems on the ouputs are reduced and the efficiency of the adapter in term data throughput (bits per second) is significantly improved.Third, each output is processed independently by means of interrupts: lines are managed in real time and lines of different speed or protocol can be supported in parallel.Fourth, the release of the resources is entirely realized on a non priority mode.
