    • A congestion control access gateway and a congestion control method for the same are provided. The congestion control access gateway interfaces between a broadband convergence network and a ubiquitous sensor network including sensors and terminals. The congestion control access gateway receives data from the ubiquitous sensor network. When a congestion situation has occurred, the congestion control access gateway detects the congestion situation based on data received in the congestion situation and broadcasts congestion notification and control messages in response to the congestion situation detection. The congestion control access gateway generates a congestion situation detection profile as a result of the congestion situation detection and performs priority queuing of the received data based on the congestion situation detection profile and service classes. The congestion control access gateway determines destination of the queued data using the congestion situation detection profile and routes the data to a corresponding service.
    • 提供了一种拥塞控制接入网关及其拥塞控制方法。 拥塞控制接入网关在宽带融合网络和包括传感器和终端的普遍存在的传感器网络之间进行接口。 拥塞控制接入网关从普遍存在的传感器网络接收数据。 当发生拥塞情况时,拥塞控制接入网关根据拥塞情况下接收到的数据检测到拥塞状况,并根据拥塞情况检测广播拥塞通知和控制消息。 拥塞控制接入网关作为拥塞情况检测的结果,生成拥塞情况检测配置文件,并根据拥塞情况检测配置文件和服务等级对接收到的数据进行优先级排队。 拥塞控制访问网关使用拥塞情况检测简档来确定排队数据的目的地,并将数据路由到相应的服务。

    • A system and method for performing a traffic process in an integrated network of a VoIP (Voice over Internet Protocol) network and a PSTN (Public Switched Telephone Network) are provided. The system includes: a softswitch which has a plurality of ASPs (Application Server Processes), transmits a data signal to other nodes through an ASP that is selected from among the ASPs, and transmits a heartbeat request message when a CPU (Central Processing Unit) utilization ratio and an SCTP (System Control Transmission Protocol) level congestion of the ASPs exceed respective reference points according to AS (Application Server)/ASP information; and a signaling gateway which updates the reference points of the CPU utilization ratio and the SCTP level congestion in response to the heartbeat request message and transmits a heartbeat acknowledgement message to the softswitch, and checks the CPU utilization ratio and the SCTP level congestion for a plurality of active ASPs within a predetermined CIC (Circuit Identification Code) or SSN (Sub-System Number) range according to the AS/ASP information, to determine the selected ASP when the signaling gateway receives data signal from outside and traffic is distributed.
    • 提供了一种用于在VoIP(因特网协议语音)网络和PSTN(公共交换电话网络)的集成网络中执行流量处理的系统和方法。 该系统包括:具有多个ASP(应用服务器处理)的软交换机,通过从ASP中选择的ASP向其他节点发送数据信号,并且当CPU(中央处理单元)发送心跳请求消息时, 利用率和ASP的SCTP(系统控制传输协议)级拥塞根据AS(应用服务器)/ ASP信息超过相应的参考点; 以及信令网关,其响应于心跳请求消息更新CPU利用率和SCTP级拥塞的参考点,并向软交换机发送心跳确认消息,并且检查多个CPU的CPU利用率和SCTP级拥塞 在根据AS / ASP信息的预定CIC(电路识别码)或SSN(子系统号)范围内的活动ASP的活动ASP,以在信令网关从外部接收数据信号并且业务量分布时确定所选择的ASP。
