摘要： In a congestion control method for a system having a first network of one congestion control unit representing a subset of a switching network constituted by a set of switching nodes connected to each other and a second network which serves as a subset of the switching network and does not have a switching node common to the first network, thereby controlling congestion of the first and second networks, the traffic is classified into first traffic generated in the first network and reaching a target switching node of the first network through a switching node in the first network, second traffic having the switching node of the first network as a start point and directed toward the second network, third traffic having a switching node in the second network as a start point and transmitted through a switching node in the second network and a switching node in the first network, and fourth traffic which does not correspond to any one of the first traffic, the second traffic, and the third traffic. Upon occurrence of congestion in the first network, the traffic flow amounts and traffic rates of the first traffic and the second traffic are limited in the first network.

摘要： A router allowing the entry hit probability of the cache to be increased is disclosed. The cache is searched using a different mask for each cache entry. A maximum or optimum cache prefix length is determined as a length of upper bits of the destination address of the received packet which are not masked by a corresponding mask. Alternatively, the cache is searched using longest prefix match (LPM). A cache entry allowing a plurality of destination addresses to be hit can be registered in the cache, resulting in increased cache hit probability.

摘要： The prior art suffered from problems such as communication quality degradation including reductions in network throughput, delays, and cell loss. An additional problem was the consumption of large amounts of the VCI and VPI required at links between nodes of each connection due to the use of a plurality of connections. In response to these problems, according to the routing system of the present invention, the plurality of connections are not changed for sections in which the routes to be taken are different but are consolidated into one connection for sections in which the routes to be taken are the same; and a connecting device provided at the node, which are set up for a plurality of connections to either or to both the input and output sides, discretionary makes either a first connection, which is either the plurality of connections or one consolidated connection, to the input side, or a second connection, which is either the plurality of connections or one consolidated connection, to the output side.

摘要： A packet switching apparatus is disclosed which is adapted to determine and control an allowed transmission rate of a transmitting terminal in a packet switching network. The packet switching apparatus comprises a rate discriminator (102) to monitor an interval of packet reception for each of connections, judge, based on the interval of packet reception, whether the transmitting terminal having sent the packet is in pause of transmission and determine a first allowed transmission rate for the transmitting terminal correspondingly to a result of the judgment, an ER calculator (109) to calculate, based on a predetermined algorithm, a second allowed transmission rate for the transmitting terminal, and an ER setter (111) to select one of the first allowed transmission rate determined by the rate discriminator (102) and second allowed transmission rate calculated by the ER calculator (109), whichever is smaller, and write it into a packet returned to the transmitting terminal.
