It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a session information statistics method according to an embodiment of the present invention, where this embodiment is applicable to a case of performing statistics on session information between an end user and an interactive system, and the method may be executed by a session information statistics apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a logic chip in a switching device, and specifically includes the following steps:
In this embodiment, the switching device may specifically be a device that performs forwarding processing on a received data packet (for example, a unicast packet or a multicast packet, and the like), and typically, the switching device may be a two-layer switch, a three-layer switch, a router, or the like. When the terminal communicates with the interactive system, the terminal usually sends the data packet to the switching device first, and the switching device forwards the data packet to the interactive system.
In this embodiment, the Logic chip may refer to a hardware unit having a preset Logic processing function in the switching Device, and specifically, the Logic chip may be implemented by a Complex Programmable Logic Device (CPLD) or a Field Programmable Gate Array (FPGA). When the terminal communicates with the interactive system, the terminal may first send the data packet to a specific switching chip in the switching device, and after receiving the data packet, the switching chip sends the data packet to the logic chip in real time.
In this step, optionally, after the logic chip receives the data packet, the session corresponding to the data packet may be identified according to the source information and the destination information in the data packet. The source information may be address information of a sender (i.e., a terminal) corresponding to the data packet, and the destination information may be address information of a receiver (i.e., an interactive system) corresponding to the data packet. Typically, the Address information may be a Media Access Control (MAC) Address, an Internet Protocol Address (IP Address), or the like. If the source information and the destination information corresponding to the two data messages are the same, the two data messages can be considered to correspond to the same session; if the source information and the destination information corresponding to the currently received data packet are different from the source information and the destination information corresponding to all the previously received data packets, it may be determined that the currently received data packet corresponds to a new session.
In a specific embodiment, after receiving a current data packet, a logic chip first extracts packet description information (that is, source information and destination information) from the current data packet, and then compares the packet description information with stored session description information (that is, stored packet description information corresponding to each session), if the packet description information corresponding to the current data packet is different from the stored session description information, it may be considered that the current data packet corresponds to a new session, and adds one to the total number of sessions in the session statistical information, and adds the packet description information corresponding to the current data packet to the session statistical information, so as to complete updating of the session statistical information.
In this embodiment, the master processor may send a session statistics query request to the logic chip at regular time, or may send the session statistics query request to the logic chip after receiving a query instruction sent by an end user. After receiving the session statistical information query request, the logic chip may transmit the currently stored session statistical information to the master processor.
In a specific embodiment, the master control processor may further be connected to a display device (e.g., a display screen) for presenting the received session statistics information to the user through the display device, so that the user can query the session statistics information; alternatively, the master processor may also send session statistics information to the terminal, so that the terminal presents the session statistics information to the user.
In this embodiment, the logic chip performs session identification on the received data packet, and updates the session statistical information according to the identification result, instead of updating the session statistical information by using the master processor, so that the problems that the session statistical information is updated in a long time and the update result is inaccurate due to a large amount of session description information received by the master processor under the condition of a large number of sessions can be avoided; and secondly, the session statistical information is updated through the logic chip, so that the updating efficiency of the session statistical information can be improved.
The technical scheme of the embodiment of the invention carries out session identification on the data message received in real time through the logic chip, updates the session statistical information according to the identification result, responds to the session statistical information query request of the main control processor in the switching equipment, and transmits the current session statistical information to the main control processor, thereby avoiding the problems of long time consumption and inaccurate update result of session statistical information update caused by receiving a large amount of session description information by the main control processor under the condition of more sessions, and improving the update efficiency of the session statistical information and the accuracy of the update result.

Wherein, the source IP address is the IP address of the sender (namely the terminal) corresponding to the data message; the destination IP address is the IP address of the receiver (namely the interactive system) corresponding to the data message; the Protocol type is a Transmission Protocol type to which the data message conforms, such as a Hyper Text Transfer Protocol (HTTP) or a Transmission Control Protocol (TCP); the source port number is a port number corresponding to a port for sending a data message in the terminal; and the port number corresponding to the port for receiving the data message in the destination port number interactive system.
In this step, optionally, target quintuple information may be extracted from the received data packet according to a preset identifier, and the target quintuple information may be compared with each quintuple information in the current session statistics information.
In this step, it may be determined whether the target quintuple information is the same as one of the current session statistics information, and if there is a quintuple information that is the same as the target quintuple information in the current session statistics information, it is determined that the target quintuple information matches the quintuple information, and the target quintuple information is considered to correspond to the same session as the quintuple information.
