摘要： In a high speed multicast route searching method of searching information of a transmission port to which a received multicast packet is next transferred: a route address is formed by coupling a receiver address and a sender address in this order; one p-th power-of-2-branch tree node is configured by a collection of one two-branch tree node and two-branch tree nodes of p−1 stages totalling ((p-th power of 2)−1) nodes just under the one two-branch tree node to form a p-th power-of-2-branch tree which is stored in a memory; not one bit but consecutive p bits of the route address coupling the receiver address and sender address in a received multicast packet in this order are checked at the same time; and in accordance with the values of the consecutive bits, a search tree stored in the memory is searched. In this manner, a search process can be completed by tracing nodes (the number of bits of a search key divided by p) times at a maximum, independently from the number of entries.

摘要： A data processing system is provided which includes a plurality of subsystems each including at least one instruction processor, at least one input/output device and at least one main storage device connected by local bus. The subsystems are connected to one another through bus extenders and inter-subsystem transfer lines. Each of the main storage devices is assigned for a partial address space as a part of the system address space. When an instruction processor or an input/output processor on each of the subsystems makes access to a main storage device, the operation of the system is as follows. If the address of access is in the address space limit of a main storage device on an inner subsystem, access to the main storage device on the inner subsystem is made. If the address of access is out of the address space limit of the main storage device on the inner subsystem and in the system address space assigned to the system, access to a main storage device on one of outer subsystems is made through a bus extender on the inner subsystem, inter-subsystem transfer lines and another bus extender on the one outer subsystems.

摘要： For setting up a connection belonging to a particular traffic class which does not make bandwidth reservation, information indicative of a priority related to cell discard declared by a source unit is stored in either of nodes in an ATM network corresponding to an identifier of the connection, such that the node selectively performs discard processing on cells belonging to the particular traffic class, when congestion occurs on the connection, in conformity to a predetermined discard condition determined by a relationship between the status of the congestion and the priority. In this way, traffics can be protected for connections having higher priorities even if they do not make bandwidth reservation.

摘要： A router comprising a priority level distinguishing means for distinguishing the priority level of a packet by referring to the information contained in the header of the packet, a routing table where an output path comprising one or more output lines can be mapped to each level of priority, an output path determining unit that searches the routing table and determines an output path to be used for sending out packets, and a preferential delivery controller that executes delivery control in accordance with the priority level for each output line corresponding to the output path. In response to a fault state in a preferred output line, the router can reroute high priority packets over an alternative output line while maintaining priority. The router may also calculate a distribution ratio to determine the optimal load for each output line for a given packet priority.
