Abstract:
A decentralised method is disclosed of deciding a common configuration parameter in a network. The network comprises at least one node designated to perform the method. In the method, a designated node makes a local decision relating to the configuration parameter in dependence upon information relating to its local operating environment (M3). The designated node sends its local decision to other designated nodes, if any, and receives corresponding local decisions made by other designated nodes, if any (M4). Following such receipt, the designated node makes a common decision relating to the configuration parameter in dependence upon its local decision and the received local decisions (M5). The common decision is made using a decision algorithm common to the designated nodes.

métodos e aparelhos para criar múltiplos modelos de perfilagem de trafego em pacote e para perfilar fluxos de trafego em pacote. modelos múltiplos de perfilagem de tráfego em pacote são criados a partir de fluxos de tráfego em pacote conhecidos que são rotulados, onde um rótulo é um valor real de um fator influenciando uma ou mais características do fluxo de tráfego em pacote conhecido. características, que são diferentes dos fatores, são medidas para cada fluxo. agrupamentos de fluxo são definidos a partir dos fluxos de tráfego rotulados, processando suas características e rótulos. os modelos de perfilagem são criados com base em informação de agrupamento. quando um fluxo de pacote desconhecido é recebido, os modelos de perfilagem de tráfego em pacote são avaliados de acordo com uma confiança e plenitude associadas a cada um dos modelos de perfilagem de tráfego em pacote. o modelo de perfilagem de tráfego em pacote com uma confiança e plenitude predeterminada é selecionado e aplicado ao perfil do fluxo de tráfego em pacote desconhecido.
Abstract:
An apparatus (30) method network server (42 43 44 46 48) and system (40) for detecting data patterns in a data stream (37) comprising a plurality of data symbols representing characters of an alphabet said apparatus (30) executing a deterministic finite automata. The apparatus comprises a state transition register (31) comprising a plurality of states (11 12 13 14 15) including a start state (11) and at least one accepting state (14) and state transitions (16a 16b 16c) from an initial state to a destination state triggered by a data symbol of the data stream (37). The apparatus (30) further comprises character position determining means (32) for determining for each data symbol of each state of the state transition register (31) a corresponding character position in the alphabet it further comprises updating means (33) for updating the state transition register (31) to comprise data symbol ranges (18x 18y) for data symbols with corresponding subsequent character positions (18b) in the alphabet triggering transitions to a same destination state. The apparatus (30) also comprises range determining means (34) for determining whether a data symbol of the data stream (37) is comprised in a data symbol range (18x 18y) of the updated state transition register (37) and determining the corresponding destination state (18b) thereof and triggering means (35) for triggering a state transition (16a 16b 16c) from the initial state to the determined destination state for detecting the data pattern.
Abstract:
Methods, a system and a computer program are provided for the execution of adaptable composed computer-implemented services having at least one integrated policy. A method comprises executing a service portion of said composed computer-implemented service 600, and executing a policy portion of the composed computer-implemented service at substantially the same time as said step of executing said service portion of said composed computer-implemented service 602. The policy portion of the composed computer-implemented service affects a behavior of the composed computer-implemented service. The policy portion of the composed computer-implemented service and the service portion of the composed computer-implemented service are integrated into a same service code 604. The service may comprise a flower delivery service where the service portion comprises a deliver real flower function and the policy portion comprises an age verification function. A method of integrating policies and services in a service refinement cycle comprises mapping a specified service to a process, the process including a policy operation affecting behavior of the service. A process outcome of policy operation is then mapped to an external service.
