  • Patent number: 5461611
    Abstract: A management system for local area networks ensures selected levels of quality of service to all transmission requests submitted to the management system. This management system is attached to the network and receives requests from all other stations on the network to reserve facilities for a particular quality of service data stream. An allocator in the management system determines if the requested facilities are available and, if so, reserves these facilities for the requesting station. If the facilities are not available, the request is denied. A hierarchical data base containing all of the current parameters of all of the network resources and all of the currently supported data streams is used to support the allocation process.

  • Patent number: 5245608
    Abstract: A method and arrangement for providing a layered communications environment for the routing of information blocks between layers to layer entities forming a logical group based on information block type and the function provided by the individual entities of the group. When an access point (AP) between layers, is first activated, it is given a group classification. As other APs between the layers are activated, they too are given group classifications. All APs between the layers having the same group classification are considered to form a single logical grouping of APs. Each of these APs can be attached to different entities in the adjacent upper layer. This logical grouping allows for information block routing from a lower layer to the adjacent upper layer based on both logical group and block type. The entities in the upper layer that are within one logical group may include separate entities for control and management functions and separate entities for data transport purposes.
