Description

METHOOD FOR DETECTING ABNORMALITY OF IPTV SERVICE, NETWORK APPARATUS AND MONITORING SERVER}

The present invention relates to a method, a network equipment and a monitoring server for determining an abnormality of an IPTV service.

In general, the IPTV service transmits a broadcast from the headend in a multicast manner, and the subscriber's set-top box receives the service and applies it to the TV.

When the set-top box sends an IGMP message to the router to determine which multicast group it belongs to, the router constructs a multicast topology through the PIM protocol between the other routers and sends the group confirmation message to the set-top box.

Since the multicast packets are replicated and delivered to the multicast group that wants to receive the multicast packets through each network facility in the topology, the amount of traffic received by the set-top box belonging to the multicast group is the same. However, since there is a high probability of receiving different TV channel contents for each set-top box, the total amount of multicast traffic between network facilities cannot be expected to match.

On the other hand, conventionally, even if an abnormality occurs in the IPTV service, a customer's complaint can be recognized only when a certain amount of complaints are received. In addition, even if the measures for the failure of the IPTV service is completed, there was a hassle to call the customer directly to check whether the service is normally provided.

In addition, failure determination method using existing network monitoring (eg network monitoring using ping, SNMP trap, etc.) is not suitable for IPTV service which is sensitive to delay or packet loss. IPTV services have been monitored using customer complaints and remote monitoring of set-top boxes. However, this method was also inadequate to determine the size and measures of service failures in a short time, and it was difficult to analyze the service in real time to cope with service failures in the quality management server that collects quality-related information of set-top boxes.

1 is a block diagram of a system for determining an abnormality of an IPTV service according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the system for determining an abnormality of the IPTV service may include a monitoring server 100, a plurality of network equipments 110, a plurality of set-top boxes 120, and a quality control server 130.

In general, each component of the IPTV service abnormality determination system of FIG. 1 is connected through a network (not shown). A network refers to a connection structure capable of exchanging information between nodes such as terminals and servers, and includes a local area network (LAN), a wide area network (WAN), and the Internet (WWW: World). Wide Web), wired / wireless data communication network, telephone network, wired / wireless television communication network, and the like. Examples of wireless data networks include 3G, 4G, 5G, 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), World Interoperability for Microwave Access (WIMAX), Wi-Fi, Bluetooth communication, Infrared communication, Ultrasound Communication, visible light communication (VLC), liFi (LiFi), and the like, but are not limited thereto.

The monitoring server 100 may determine whether there is an abnormality of the IPTV service by comparing the amount of multicast traffic received from each of the plurality of network equipments 110 as a server that determines whether there is an abnormality of the IPTV service. Here, the plurality of network equipment 110 may be equipment that provides IPTV service to at least one set-top box grouped in each network equipment 110.

In detail, the monitoring server 100 allocates a monitoring port from each of the plurality of network devices 110, and provides information on the amount of traffic received from the monitoring port allocated to each of the plurality of network devices 110. Received from each, it is possible to determine whether there is an abnormality of the IPTV service in each network equipment 110 based on the information on the traffic volume for each of the plurality of network equipment (110).

In addition, the monitoring server 100 may determine whether there is an abnormality of the IPTV service by using the quality information transmitted from the plurality of set-top boxes 120 to the quality management server 130.

For example, the monitoring server 100 may count the number of quality information whose quality is equal to or less than a threshold value for each IP assigned to the plurality of set-top boxes 120, and may report whether the IPTV service is abnormal to the network operator based on the number of quality information. .

Hereinafter, the operation of each component of the system for determining an abnormality of the IPTV service of FIG. 1 will be described in more detail.

2 is a block diagram of the monitoring server 100 shown in FIG. 1, in accordance with an embodiment of the present invention.

2, the monitoring server 100 may include a monitoring port allocating unit 200, a traffic volume receiving unit 210, an abnormality determining unit 220, and a quality monitoring unit 230. The quality monitoring unit 230 may include a filter unit 232 and a filter unit 232. However, the monitoring server 100 shown in FIG. 2 is only one implementation example of the present invention, and various modifications are possible based on the components shown in FIG. 2. Hereinafter, a description will be given with reference to FIG. 3 along with FIG. 2.

The monitoring port allocator 200 may allocate at least one of the plurality of ports 300 of each of the plurality of network equipment 110 providing the IPTV service to the plurality of set top boxes 120 as the monitoring port. For example, the monitoring port allocator 200 allocates at least one port 310 of the plurality of ports 300 of the first network equipment 112 as a monitoring port, and the plurality of second network equipment 114. At least one port 310 of the port 300 may be allocated as a monitoring port.

Each of the plurality of network equipment 110 may have a plurality of ports 300 including a transmit (Tx) port and a receive (Rx) port. Here, the Tx port is a transmission port used when transmitting one channel among the plurality of channels received from the broadcast server to the set-top box, and the Rx port is a receiving port used when receiving a plurality of channels from the broadcast server.

Here, the Tx port and the Rx port of the port 310 allocated as the monitoring port among the plurality of ports 300 are looped. Traffic volume for the channel for receiving traffic received at the monitoring port 310 through the looped monitoring port 310 may be collected.

The traffic monitoring circuit configuration method of the present invention will be described in detail with reference to 4a to 4c. 4A is a diagram illustrating a conventional traffic monitoring circuit configuration method.

Referring to FIG. 4A, according to the conventional traffic monitoring circuit configuration method, it may be considered to collect a total amount of multicast traffic by directly connecting a cable between each network equipment 110 and the monitoring server 100. As such, when a cable is directly connected between each network device 110 and the monitoring server 100, it is not a problem when operating a small network in the same area, but for a large network, there are limitations in terms of work time and cost. . That is, in the case of a large network, there is a problem that it is difficult to build such a system.

Figure 4b is a diagram showing a traffic monitoring line configuration method of the present invention. Referring to FIG. 4B, the traffic monitoring circuit configuration method of the present invention loops (ie, connects a Tx port and an Rx port) allocated to each network device 110 to collect multicast traffic. Can be.

4c is a diagram illustrating a traffic monitoring circuit configuration method of the present invention applied to actual equipment. Referring to Figure 4c, by looping the Tx port and Rx port constituting the monitoring port of the network equipment to make the state of the monitoring server up state, there is no need for link configuration with the counterpart equipment.

On the other hand, the port looping processing method in the existing Ethernet network environment may pose a serious risk. Specifically, if the network device clearly knows the port of the destination MAC address, it forwards the data packet only to that port, but if it does not know the port of the destination MAC address, or because of the nature of the MAC address, it should forward the incoming port. Float the data packet to all ports except the one.

Due to the operation characteristics of the network devices, when a looping network is configured between ports, broadcasting storms may occur in which data packets are repeatedly transmitted between the ports indefinitely. Increasing the load, the network equipment is also overloaded with CPU, there is a risk of loss of network function.

In order to eliminate the cause of such a broadcast storming phenomenon, the present invention is configured differently from a general service port by applying a filter to a monitoring server that drops a data packet received at a looped Rx port to a monitoring server. This allows the Rx port at the monitoring port to drop all data packets received from the Tx port to prohibit broadcasting storming.

2 and 3, one port 310 of the plurality of ports 300 provided for each of the plurality of network equipments 110 may be used as a monitoring port.

In this case, a predetermined traffic reception channel is received through at least one port 310 allocated as a monitoring port to each network device 110, and a plurality of airwave channels transmitted from a broadcasting server are received through the remaining ports. Can be. At least one channel (corresponding to a channel requested by the set-top box) of the plurality of airwave channels preset to the plurality of set-top boxes 120 grouped in each network device 110 through the remaining ports except the monitoring port 310 Can be sent. Here, the predetermined traffic reception channel may include a plurality of preset airwave channels and a plurality of control channels.

Each of the plurality of network equipment 110 may receive a plurality of channels for receiving the same preset traffic from the broadcaster server. For example, each of the first network equipment 112 and the second network equipment 114 may include a plurality of preset air channel (seven broadcast channels such as KBS channel, EBS channel, JTBC channel, and the like) through the monitoring port 310. A traffic reception channel including a MBN channel and the like and a plurality of control channels (12 control channels, for example, an SI-ACAP channel, an SI-WEB channel, and an SI-UHD channel, etc.) may be similarly received from a broadcaster server.

On the other hand, when collecting the traffic volume in each of the monitoring port 310 of the plurality of network equipment 110, because the bandwidth of 11Mbps per full HD level channel is minimized to minimize the consumption of bandwidth, the ideal of the national IPTV service To determine the presence or absence, IGMP static-join can be set for the most popular over-the-air channels.

The monitoring port 310 of the plurality of network equipment 110 may receive a plurality of preset airwave channels transmitted by multicast from a broadcaster server in an IGMP static-join manner. By using the IGMP static-join method, the plurality of network equipments 110 do not need to join a plurality of airwave channels one by one to process unnecessary streams, and minimize waste of CPU resources, thereby providing a smooth IPTV service. .

Traffic amount receiving unit 210 is information on the amount of traffic received by at least one monitoring port 310 from each of the plurality of network equipment 110 (traffic for the channel for receiving traffic received at each network equipment 110) Amount) can be received. At this time, the same traffic reception channel is transmitted to the monitoring port 310 assigned to each of the plurality of network equipment 110 in a multicasting manner.

The traffic volume receiver 210 may receive information on the traffic volume from each of the plurality of network equipments 110 using the Simple Network Management Protocol (SNMP) protocol. For example, the traffic volume receiver 210 receives information on the traffic volume of the traffic reception channel received from the monitoring port 310 of the first network equipment 112 from the first network equipment 112, The second network equipment 114 may receive information on the traffic volume of the traffic reception channel received at the monitoring port 310 of the second network equipment 114.

The abnormality determination unit 220 may determine the abnormality of the IPTV service in the plurality of network equipment 110 based on the information on the traffic volume. For example, the abnormality determination unit 220 compares whether the traffic volume of the traffic reception channel received from the first network equipment 112 and the traffic volume of the traffic reception channel received from the second network equipment 114 are the same. It is possible to determine whether there is an abnormality in the IPTV service.

If the traffic volume of the traffic reception channel received from the first network equipment 112 and the traffic volume of the traffic reception channel received from the second network equipment 114 are the same, the abnormality determination unit 220 may determine whether the traffic information is the first. If it is determined that the IPTV service of the network equipment 112 and the network equipment 114 is normal, and the traffic volume of the first network equipment 112 and the second network equipment 114 are different, the abnormality determination unit 220 may determine that there is a problem with the IPTV service of the network equipment with low traffic volume.

Hereinafter, a description will be given with reference to FIGS. 2 and 5. 2 and 5, the quality monitoring unit 230 uses the quality information 500 transmitted from each of the plurality of set top boxes 120 to the quality management server 130 for each set top box 120. Monitor the quality of IPTV services.

At this time, the plurality of set-top boxes 120 includes the quality information 500 for each IPTV service in the SNMP trap (TRAP) message to the quality management server 130, the quality management server 130 is SNMP The quality information 500 collected through the trap message may be analyzed and reported periodically.

The filter unit 232 may filter an analysis target packet among packets for quality information. For example, the filter unit 232 first filters the packet to be analyzed from the packet for the quality information, and then classifies two kinds of quality-related error packets (for example, 'channel black packet' and 'screen dropped packet') from the packet to be analyzed. ) And network error type 2 packets (eg, 'SI channel join failure packet', 'unbound join failure packet').

For example, the quality monitoring unit 230 aggregates the number of set-top boxes that transmit quality information indicating direct service abnormalities, such as 'black screen' and 'screen truncation', among the quality information included in the SNMP trap message in real time. It can detect whether or not it occurred.

For example, the quality monitoring unit 230 may aggregate in real time the number of IPs of the set-top box that has transmitted two kinds of quality-related error packets or two kinds of network errors. At this time, the IP information about the set-top box that has transmitted the quality-related error type 2 packet or the network error type 2 packet aggregated above the threshold value may be output to the web screen of the network manager terminal.

In addition, the quality monitoring unit 230 utilizes pool information of a DHCP (Dynamic Host Host Configuration Protocol) server (not shown) to provide network block and accommodating equipment information to which a poor quality set-top box belongs, resulting in network abnormalities. It can provide information to respond immediately to the IPTV service failure situation. Here, a DHCP server (not shown) allocates IP to each set top box 120 that is arranged for each main node of each region to provide IPTV service. At this time, the DHCP server (not shown) stores the IP block information to be allocated to each set-top box 120, a DHCP poll name (pool name) for distinguishing the service identifier and the terminal L3 equipment.

The quality monitoring unit 230 maps the information stored in the DHCP server (not shown) and the quality information 500 to the IP assigned to each set-top box 120 to provide information that can be utilized for failure response of the set-top box. It can be provided to the manager terminal.

On the other hand, those skilled in the art, monitoring port allocator 200, traffic volume receiving unit 210, abnormality determination unit 220, quality monitoring unit 230, and filter unit 232 are each implemented separately, or It will be appreciated that more than one can be implemented in an integrated manner.

6 is a flowchart illustrating a method of determining whether an IPTV service is abnormal in the monitoring server 100 according to an embodiment of the present invention.

Referring to FIG. 6, in operation S601, the monitoring server 100 may allocate at least one of a plurality of ports of network equipment that provides an IPTV service as a monitoring port. In this case, a predetermined traffic reception channel may be received through at least one monitoring port.

In operation S603, the monitoring server 100 may receive information on the traffic amount received by the at least one monitoring port from the network equipment.

In operation S605, the monitoring server 100 may determine whether an IPTV service is abnormal in the network equipment based on the information on the traffic volume.

In the above description, steps S601 to S605 may be further divided into additional steps or combined into fewer steps, according to an embodiment of the present invention. In addition, some steps may be omitted as necessary, and the order between the steps may be changed.

Here, the traffic reception channel receiver 700 may include a filter unit 702. However, the first network equipment 100 shown in FIG. 7 is just one implementation example of the present invention, and various modifications are possible based on the components shown in FIG. 7.

The traffic reception channel receiver 700 may receive a traffic reception channel through at least one monitoring port among a plurality of ports. Here, each of the plurality of ports includes a Tx port and an Rx port. The Tx port is a transmission port used when transmitting one channel among the plurality of channels received from the broadcaster server to the at least one set top box, and the Rx port is a receiving port used when receiving a plurality of channels from the broadcaster server. At this time, the Tx port and the Rx port of the monitoring port may be looped to collect traffic volume for the channel for receiving traffic.

The traffic reception channel receiver 700 may receive a plurality of preset airwave channels through the monitoring port 310 in an IGMP static-join manner. For example, the traffic reception channel receiver 700 receives a plurality of preset air channels transmitted by multicast from a broadcaster server in an IGMP static-join method, and joins the plurality of air channels one by one to perform unnecessary stream processing. And minimizing the waste of CPU resources can provide a smooth IPTV service.

The filter unit 702 may drop a packet received at the looped Rx port. Specifically, in order to prevent broadcasting storming that may occur due to the looping of the Tx port and the Rx port of the monitoring port 310, the filter unit 702 may filter the packet received at the Rx port of the monitoring port. Can be dropped. Here, the broadcasting storming phenomenon is a phenomenon in which a data packet is repeatedly transmitted indefinitely between ports when a looping network is configured between the ports, which causes overload of network equipment and loss of network function.

The mirroring unit 720 may mirror a packet for quality information transmitted from each of the plurality of set top boxes 120 to the quality control server 130. For example, the mirroring unit 720 may mirror the quality information transmitted to the quality control server 130 through a mirroring device (for example, a TAP device) installed on the top of the quality control server 130. For example, the mirroring unit 720 may mirror the packet of the quality information by duplicating the SNMP trap message transmitted from each of the plurality of set-top boxes 120 to the quality management server 130.

The traffic volume transmitter 710 may transmit the information on the traffic volume received through the monitoring port 310 to the monitoring server 100. Here, the monitoring server 100 may determine whether there is an abnormality of the IPTV service in the first network equipment 112 based on the information on the traffic volume.

The traffic volume transmitter 710 may transmit the information on the traffic volume to the monitoring server 100 using a simple network management protocol (SNMP) protocol.

On the other hand, those skilled in the art, each of the channel receiving unit 700, the filter unit 702, the traffic amount transmitting unit 710 and the mirroring unit 720 for receiving traffic may be implemented separately, or one or more of them may be integrated. I will understand enough.

An embodiment of the present invention may also be implemented in the form of a recording medium including instructions executable by a computer, such as a program module executed by the computer. Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, computer readable media may include all computer storage media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data.
