Title
(EN) Data flow classification method and message forwarding equipment
(ZH) 数据流的分类方法和报文转发设备
Abstract
(EN) The embodiment of the invention discloses a data flow classification method, which is applied to message forwarding equipment between an internal network and the Internet. The method provided by the embodiment of the invention comprises the following steps: message forwarding equipment acquires a plurality of data streams, and extracts address information and time information of each data stream in the plurality of data streams; according to the source IP address of each data stream, a data stream set generated is screened when a first client device accesses the plurality of services from theplurality of data streams; according to the destination IP address and the destination port number of each data stream in the data stream set, a service set which is accessed by the first client device and comprises a first service and a second service is confirmed; the correlation among services is determined in the service set according to the time information of each data flow in the data flowset so that first service and second service are used for realizing a first application. therefore, the message forwarding device determines that the data streams corresponding to the first service and the second service are the data streams of the first application.
(ZH) 本申请实施例公开了一种数据流的分类方法,应用于内部网络和互联网之间的报文转发设备。本申请实施例方法包括:报文转发设备获取多条数据流,并提取多条数据流中每条数据流的地址信息和时间信息;根据每条数据流的源IP地址,从多条数据流中筛选出第一客户端设备访问多个服务产生的数据流集合;根据数据流集合中每条数据流的目的IP地址和目的端口号,确定第一客户端设备访问的包括第一服务和第二服务的服务集合;根据数据流集合中每条数据流的时间信息,确定服务集合中的各服务之间的相关性;进而确定第一服务和第二服务用于实现第一应用;由此报文转发设备确定第一服务和第二服务对应的数据流为第一应用的数据流。
