摘要： After a source address, a destination address, a source port number, and a destination port number are extracted from a communication message and a communication connection and the direction of the communication connection are specified, transmitted/received message amounts every a predetermined elapsed time are determined for each communication connection. Next, a correlation between communication connections is calculated by using the transmitted/received message amounts determined for each communication connection. A server group in which a communication connection group with a high correlation is established is specified and a multilevel system that includes specified servers is determined.

摘要： For each of a plurality of signal processors accommodating respective shares of signalling links to be controlled by a signalling point, a congestion-condition level is determined by comparing an overload condition of a central controller and the number of processed signals with their respective threshold values. Any signalling link, whose priority is lower than the priority corresponding to the determined congestion-condition level, is inhibited for use, and a signalling link accommodated in another signal processor is substituted for the inhibited signalling link. In determining the congestion-condition level, a decision is made at predetermined intervals of time as to whether the condition is a congested condition or a congestion cleared condition; if it is a congested condition, the congestion-condition level is raised, and if it is a congestion cleared condition, the congestion-condition level is lowered.
摘要翻译：对于容纳要由信令点控制的信令链路的各自共享的多个信号处理器中的每个信号处理器，通过将中央控制器的过载条件和处理的信号的数量与它们各自的阈值进行比较来确定拥塞状态等级。优先级低于对应于确定的拥塞状态等级的优先级的任何信令链路被禁止使用，并且容纳在另一个信号处理器中的信令链路被替代被禁止的信令链路。在确定拥塞状态等级时，以预定的时间间隔作出关于条件是拥塞状态还是拥塞清除条件的判定; 如果是拥塞状态，则拥塞状态等级提高，如果是拥塞清除条件，则拥塞状态等级降低。

摘要： A packet identification device has a reception unit that successively receives packets. The device has an obtaining unit that obtains, every time a packet is received, an interval of reception times between the received packet and a packet received immediately before the received packet, in the same connection as that of the received packet. The device has an identification unit that identifies the received packet as a packet containing a forefront segment of a plurality of segments constituting one message when the obtained reception time interval is higher than a predetermined threshold value.
