摘要： An edge switch for an Ethernet network maintains look-up tables of media access control addresses and network addresses for local sources and destinations at least two sub-nets, so that it can forward packets directly even when the local source and destination are on different sub-nets and forwards packets to a core router when the destination is not local to the edge switch.

摘要： A method and processing device for controlling the communication of data associated with a user on a network 1 is described, in which the communication of data to and from a user is controlled according to user profile information. In a preferred embodiment, the user profile information is maintained in a database 9 accessible to processing devices 5 providing access to the network 1, and includes a volume allowance for a predetermined time period, a maximum transmission rate and current usage information for the user. Each time a user connects to the network 1, the method determines whether the user is within the volume allowance, and if so, permits access to the network 1. The communication of data is controlled according to the maximum transmission rate. The method may be implemented in software.

摘要： A classification search engine for the application of classification rules to a data packet comprises a rules engine for applying a succession of rules, each rule including an operating code. At least some rules are each a single rule of which the operating code specifies a respective portion of the packet, such as a longword, for the extraction of data for the application of the respective rule. Each single rule includes a mask field for controlling the application of the single rule to the data. Other rules are multiple rules of which the operating codes identifies the rule as a multiple rule and which includes a mask for controlling the application of the multiple rule to the results of the application of a multiplicity of single rules to the packet. The operating code for a single rule specifies a pre-determined packet type and a decoder will determine whether a packet conforms to this type (which may be specific or generic) before allowing the application of the rule to the packet.
