Description

System and Method for Managing and Providing Sequential Quality of Service Information

The present invention relates to a system and method for managing and providing sequential quality of service (Sequential QoS) information, and more particularly, to copy packets passing along a network link from a terminal through an electrical scheme in real time. The present invention relates to a system and method for providing QoS information by processing and managing a quality indicator (QI) for each user by detecting, processing, and analyzing a packet through a packet filtering rule.

Today's TCP / IP networks suffer from frequent bottlenecks and congestion due to the explosive growth of Internet usage and increased traffic, and as a result, the quality of network services is becoming more and more serious. In addition, indiscriminate service congestion caused by the emergence of various web-based applications does not guarantee stable services for core tasks. As network utilization increases, there is an increasing demand for stable network service base construction, and service operators are in urgent need of efficient traffic control and bandwidth management for optimal network operation and management.

To solve these problems, until now, there has been no other way than to increase the bandwidth of the circuit. However, such line additions have to bear high costs and are limited in addressing the constantly increasing traffic problem. Not only is Internet traffic quantitatively increasing, but various changes in its nature are also taking place, and change factors must be considered to meet new demands. However, the current best effort network has a problem in that it cannot fundamentally guarantee the quality of a user's important service because it cannot prevent bandwidth monopoly of specific traffic.

Recently, the QoS (Quality of Service) solution has emerged as a solution for various user demands for efficient service quality and efficient network operation, and has become an essential core element of the network, not a temporary alternative to solve the current network problem. Doing.

QoS solution refers to various technologies and concepts that systematically manage traffic and bandwidth in a limited bandwidth by differentiating service levels provided to users or applications according to importance. The QoS solution does not simply increase the network bandwidth by increasing the limited bandwidth, but effectively monitors and analyzes the bandwidth and the traffic generated therein to effectively configure and manage the policy-based network and improve the network management. It is.

In a typical QoS solution, a special dedicated device is installed in a network device such as a gateway of a network or in front of a server in order to collect QoS information, and an average delay in a network device such as a gateway, an average amount of change in a cell group, and a cell loss QoS information is grasped by measuring information such as transmission error rate and transmission error rate. However, it is difficult to collect accurate information because most of the problems in the network operation process are caused by network congestion rather than defects of network equipment. Therefore, there is a demand for a QoS solution centered on users, not quality control using statistical elements extracted from network equipment.

In order to solve the above problems, the present invention, by sequentially copying the packet passing along the network link from the terminal in an electrical manner, and by detecting, processing and analyzing the packet through the packet filtering rules, the quality of service sequential for each user It is an object of the present invention to provide a system and method for providing QoS information by processing and managing an indicator (QI).

1 is a block diagram schematically showing the configuration of a SANQ system 100 according to a preferred embodiment of the present invention.

The service availability and network quality (SANQ) system 100 according to the preferred embodiment of the present invention includes a SANQ agent 110, a web server 120, a QoS manager 130, a database server 140, a database 150, and the like. It includes.

The SANQ system 100 is a system that manages and provides sequential QoS information of a wireless Internet service provided by a mobile communication service. The system can be applied to wired Internet Protocol (IP) networks in the same shape.

The SANQ agent 110 functions to copy packets passing along the network link from the terminal in real time, detect packets based on packet filtering rules, and measure and transmit sequential service quality information.

The web server 120 functions to provide a web service so that an operator can monitor sequential service quality information received from the SANQ agent 110. On the other hand, when the operator and the information management system system is linked to another interface, for example, CORBA, the function of the web server 120 of the present invention may be performed by the QoS manager 130 having a network interface function. That is, when using an interface other than the web, the web server 120 is not necessary, and the QoS manager 130 or the SANQ agent 110, which will be described later, uses a service level agreement (SLA) or operation through an open interface. The sequential service quality information may be provided in connection with an operation support system (OSS) management system.

The QoS manager 130 functions to manage several pieces of sequential quality of service information received from several SANQ agents 110 when there are several physical network links. The database server 140 integrates and manages data collected by the SANQ system 100, and the database 150 is a space for storing such data.

2 is a block diagram showing the hardware configuration and data flow of the SANQ agent 110 and the QoS manager 130 according to an embodiment of the present invention.

The SANQ agent 110 includes a probing device 200, a QoS analyzer 210, and the like, and the QoS manager 130 includes a data and control hub 220, a SANQ QoS server 230, and the like.

The probing device 200 includes a tapper 201 and a filter 202. The tapper 201 copies a packet passing along a network link from a terminal in an electrical manner in real time and filters the filter. In 202, a packet is detected through a packet filtering rule set for sequential measurement of quality of service information.

The QoS analyzer 210 is a device that processes and processes packets detected through the probing device 200 to calculate and manage a sequential quality indicator (QI) of each user and perform statistical processing in real time. QoS analyzer 210 is distributed for decoding of WAP packets among packets transmitted through probing device 200 and L2 S / W 211 used to distribute packets detected through probing device 200. Gathering unit 212 performing the pre-processing function, the analysis unit 214, Gathering unit for calculating and managing the sequential service quality indicators of each user from the processing result of the gathering unit 212 and statistical processing in real time The data hub 213 serving as a relay device for data transmission and reception between the 212 and the analysis unit 214, and the analysis database 215 for storing and managing the processing results of the quality indicators for each measurement unit of the quality index. Include.

Here, the quality indicators include Service Setup Quality, Service Setup Time / Throughput, Service Session Quality, and Service Re-Setup Quality. / Time) and the service closure time of the service. Detailed description thereof will be described later.

The analysis database 215 is a QI database (not shown) that stores the processing result of the analysis unit 214 for each measurement unit of the quality indicator and a session information database that stores separate session information for restoring the list of the quality indicator. (Not shown). At this time, the session information includes a mobile identification number (MIN), a sequential quality of service number, a user-agent field, a session number, a service type, a session start time, a session end time, and whether the service is normally terminated. The reason for backing up the quality indicators to the analysis database 215 for each measurement unit is that the system load of the analysis unit 214 becomes large when all the processing results for all users are maintained in the analysis unit 214.

The data and control hub 220 is a control signal between the data hub 221 and the analysis unit 214 and the QoS server 231 serving as a relay device for data transmission and reception between the analysis unit 214 and the QoS server 231 which will be described later. A control hub 222 acts as a relay device for transmitting and receiving.

The SANQ QoS server 230 is a QoS server that graphically processes the processing results of the sequential service quality indicators of the users transmitted through the data hub 221 in a form that is easy for the operator to understand and provides them in the form of a graphical user interface (GUI). 231 and a QoS database 232 for storing and managing processing results performed by the QoS server 231.

3 is a flowchart briefly illustrating a process of managing and providing sequential service quality information according to an exemplary embodiment of the present invention.

First, the packet passing along the network link from the terminal is copied in real time in the tapper 201 of the probing device 200 in an electrical manner, and the filter 202 detects the packet through the packet filtering rule (S300). In this way, the WAP packet among the detected packets should be preprocessed for decoding. In a preferred embodiment of the present invention, when the amount of the received WAP packet is large, the WAP packet is distributed through the gathering unit 212 for more efficient preprocessing. (S302). The analysis unit 214 calculates and manages a sequential service quality index of each user from the processing result of the gathering unit 212 and performs statistical processing in real time (S304). The statistical processing result processed in this way is managed in a memory (not shown) of the QoS analyzer 210 and then stored in the analysis database 215 for each measurement unit of the quality indicator (S306). The QoS server 231 processes the received processing result of the sequential service quality index of each user graphically and provides it in the form of a GUI (Graphic User Interface) which is easy for the operator to understand (S308). In order to be used as more accurate information for each terminal, these processing results are divided and provided based on the base station sector unit, terminal type, browser type, and service type to which each terminal belongs. .

4 is a flowchart illustrating a process of measuring sequential service quality indicators according to a preferred embodiment of the present invention.

As shown in Fig. 4, a plurality of analysis lists for sequential quality of service for a service user (MIN number) of the present invention are managed. The flowchart of FIG. 4 is for one analysis list.

First, when the PPP (Point to Point Protocol) is set up (S400), the quality of the service from the time when the terminal downloads the first page provided by the wireless Internet service of the present invention to the stage before receiving the streaming / download service is provided. Measure and analyze the set quality / time / speed (Service Setup Quality / Time / Throughput) (S402). Next, the user of the terminal measures and analyzes the service session quality (Service Session Quality), which is the quality at the stage of receiving the streaming / downloading service (S404), and the user uses the inheriting function to stream the detailed service of the service. Alternatively, the service re-setup quality / time, which is the quality of the service after receiving the download service and before receiving the other detailed service, is measured and analyzed (S406). Finally, the service closure time, which is the quality at the stage of completely exiting from the wireless Internet service, is measured and analyzed (S414).

As shown in FIG. 4, the steps of measuring and analyzing the service session quality and the measuring and analyzing the set quality / time / speed of the service are repeated several times (S408 to S412). This is a factor that is considered because one terminal may be provided with multiple streaming / download services through the resuming function without completely exiting from the wireless Internet service of the present invention.

5 is a diagram illustrating a list of quality indicators (QIs) calculated and managed according to a preferred embodiment of the present invention.

The QoS analyzer 210 should calculate and manage the quality indicators of FIG. 5 for all users currently connected to the wireless Internet service of the present invention. For this purpose, the memory of the QoS analyzer 210 for each quality indicator measurement unit of each user is calculated. After the management is performed (not shown), the data is backed up to the analysis database 215.

The user of the wireless Internet service of the present invention accesses the wireless Internet in order to use various services provided by the service, and then downloads the top menu page to the terminal. The user selects a desired detailed service while performing navigation based on the top-level menu page downloaded to the terminal, from which the streaming or downloading process of the content is performed according to the selected service. The set quality item 500 of the service represents a quality index for measuring the quality of the WAP-related quality from the time when the user downloads the top menu page, which is the first page provided by the service, to the stage before the first detailed service of the service is provided. Item. Detailed quality indicators of the set quality indicators include the number of WAP gateway connection retries and the success rate of the WAP gateway connection. The unit of measurement of the service setting quality may be expressed as '%'. In addition, if it is determined that there is no response within a predetermined time for the download request of the menu page, a specific event is generated. When an event for such a failure call occurs, the terminal of the terminal is analyzed to analyze the cause of the failure. The RF (Radio Frequency) status, an error in network configuration equipment, a PPP link setup error or a signaling error, and the like are considered as targets of the failure.

Although the service setting quality and the setting time / speed of the service are shown in the same item in FIG. 5, the two items are managed and analyzed as separate items. Since the time and throughput elements are the main elements of the quality measurement of the multimedia, it is more preferable to manage them separately from the quality of service setting. The setting time / speed item 500 of the service is an item indicating a quality index for measuring the time until the user first receives the detailed service and the speed when downloading the service related WAP page. The detailed quality indicators of the set time / speed quality item of the service include the download time of the first page provided by the service, the download speed, the download time and the download speed of the menu provided by the service. The service setting time / speed quality index is expressed in the form of PDF (Probability Density Function) and CDF (Cumulative Distribution Function) using statistical data. On the other hand, when a user accessing the wireless Internet service of the present invention retries the same menu page, a retry request may be found through sequence analysis of a menu request packet, and at this time, a cause of retries may occur. Analyze If the download time and download speed exceed the specified threshold, an event will occur and the cause will also be analyzed.

The wireless Internet service of the present invention is classified into a streaming service and a download service. The service user performs various procedures necessary for the service selected by the user through the service setting process, and then performs the streaming or download process in earnest. In addition, service users may continue to be provided with streaming / download services for other Video on Demand (MoD) / MoD (Music on Demand) contents through the function of resuming while accessing the wireless Internet service of the present invention. The quality for this inheritance function may be indicated using the service session quality items 502 and 506 and the service reset quality / time item 504. The session quality items 502 and 506 of the service are items representing quality indicators for measuring the quality of the detailed service in the process of the terminal receiving the selected detailed service after the user of the service selects the detailed service, as shown in FIG. 5. Likewise, it is represented as two aspects of the download item 502 and the streaming item 506. The detailed quality indicators of the download item 502 among the session quality items of the service are the download time, the download speed, and the download success rate of the content, and the detailed quality indicators of the streaming item 506 include the streaming setup time, the streaming rate, the packet delay variation, Packet loss rate, packet header error rate, streaming end time, and streaming success rate. Download success rate and streaming success rate are respectively calculated using detailed quality indicators. That is, the download success rate is expressed as a value of 0 or 1 as an indicator for indicating that the download was successful when all the detailed quality indexes related to the download satisfy the threshold set by the operator. Streaming success rate also has the same meaning as download success rate.

After the service user is provided with the streaming / download service, the user can navigate other VoD / MoD contents by using the resume function without exiting the wireless Internet service of the present invention and stream / download the selected VoD / MoD contents. The resetting quality / time item 504 of the service is an item indicating a quality index for measuring the quality of the service from the time when the user receives the detailed service to the stage before receiving the other detailed service by using the inherit function. Detailed quality indicators of the reset quality / time item 506 of the service include the number of WAP gateway connection retries, the success rate of the WAP gateway connection, and the download time of a menu provided by the service. Here, the detailed quality indicator of the reset quality / time item 506 of the service is a component of the service setting quality and the service setting time / speed item 500 and is measured using the same measurement method. Probing device 200 is passed to the QoS analyzer 210 without this distinction, the received QoS analyzer 210 receives the service setting quality / time / speed items (depending on whether the request / response for the first page is included) ( 500) and service reset quality / time item 504.

The end time of the service is recognized as a case in which no transaction occurs between the terminal and the system providing the service or the first page provided by the service is downloaded to the terminal for a predetermined elapsed time. The QoS analyzer 210 records service start time and service end time for each user.
