35 results about "Multiple aggregation" patented technology

Various systems and methods that allow multiple aggregation protocol sessions to be established in a daisy chain network are disclosed. One method involves sending a first aggregation protocol packet and a first session identifier associated therewith to a first network device via a first interface and sending a second aggregation protocol packet and a second session identifier associated therewith to a second network device via the first interface.

The invention relates to a bandwidth allocation method of a differentiated services architecture network. The method comprises the following steps: dividing the network traffic into a plurality of aggregation classes; calculating the bandwidth ratio and the queue increment ratio of the plurality of aggregation classes; class traffic load; calculate the traffic load ratio according to the traffic load; obtain the bandwidth of the aggregation class according to the traffic load ratio and weight parameters; obtain the target bandwidth size of multiple aggregation classes according to the bandwidth. The implementation method of the invention is simple and efficient, has extremely short response time, and does not introduce any unstable factors to the network.

The invention discloses a topology control method of a wireless sensor network used for monitoring the water quality of an inland river. The topology control method comprises a network initialization stage, a clustering stage, a cluster head election stage, an in-cluster communication stage and an inter-cluster communication stage. Aimed at the wireless sensor network which is used for monitoring the water quality of the inland river and characterized by multiple aggregation nodes and long-distance bilinear distribution, the topology control method divides the wireless sensor network into virtual grids same in size, and all active sensor nodes in each virtual grid constitute a cluster. In each turn, nodes with low communication cost and high residual energy are selected to serve as clusters, other nodes transmit monitoring data to the clusters in a single-hop data transmission mode, data fusion is conducted on the clusters, the data are transmitted to the near aggregation nodes in an inter-cluster multi-hop data transmission mode, and if a path is blocked, the data are reversely transmitted to the far aggregation nodes. The topology control method effectively prolongs the life cycle of the network, balances the load of the network, and optimizes the performance of the network.

The invention relates to a caching optimization method and system for resisting attacks of continuously changing domain name prefixes. The method includes: every set period of time, caching domain name server statistics records of non-existing domain names, and starting automatic aggregation of domain names when the records of non-existing domain names exceed a set threshold; The exact match of the domain name is divided into multiple aggregation categories. If the number of elements in the aggregation category exceeds the set threshold, all the domain names in the aggregation category will be aggregated into an aggregate domain name prefixed with *; for a new domain name query request, if the caching domain name server If there is no corresponding specific record in , it will be matched with the aggregated domain name. If the match is successful, a response that the domain name does not exist will be returned. Otherwise, the domain name query will be made to the authorized domain name server. The method of the invention has the advantages of strong cache stability, high real-time performance, saving cache space and the like.
