Description

Method for determining abnormality of IPTV service, network equipment and monitoring server

The present invention relates to a method for determining whether an IPTV service is abnormal, network equipment, and a monitoring server.

In general, the IPTV service transmits “broadcasting” from the headend in a multicast method, and the set-top box of the subscriber receives it and applies it to the TV.

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

Since the multicast packet is duplicated and delivered to the multicast group that wants to receive the multicast packet whenever it passes 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 that each set-top box actually receives different TV channel contents, it cannot be expected that the total amount of multicast traffic between network facilities is identical.

On the other hand, in the prior art, even if an IPTV service malfunction occurs, service failure can be recognized only when customer complaints are received at a certain level or higher. In addition, even if measures for IPTV service failure are completed, it is inconvenient to directly check whether the service is normally provided by calling the customer.

In addition, the existing system-based network monitoring (e.g., network monitoring using ping, SNMP trap, etc.) is not suitable for IPTV services that are sensitive to delay or packet loss. IPTV services have been monitored using methods such as customer service complaints and remote monitoring of set-top boxes. However, this method was also inappropriate for determining the scale of service failure and measures to be taken in a short time, and it was difficult to perform real-time analysis to cope with service failure even in the quality control server that collects quality-related information of the set-top box.

Korean Patent Registration No. 10-1331853, a prior art, discloses a configuration for receiving a plurality of error messages from each of a plurality of devices (IPTVs) of a home network system and determining an error occurrence area from the received error messages.

The present invention is to solve the problems of the prior art described above, and allocates at least one of a plurality of ports of network equipment providing IPTV service as a monitoring port, and measures the amount of traffic received in the allocated at least one monitoring port. Based on the information, it is intended to determine whether or not there is an abnormality in the IPTV service in the network equipment. However, the technical problem to be achieved by the present embodiment is not limited to the technical problems described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, the method for determining whether an IPTV service is abnormal in a monitoring server according to a first aspect of the present invention monitors at least one of a plurality of ports of network equipment providing the IPTV service. allocating to ports; receiving information about the amount of traffic received by the at least one monitoring port from the network equipment; and determining whether or not the IPTV service is abnormal in the network equipment based on the information on the amount of traffic, wherein a channel for receiving traffic can be received through the at least one monitoring port.

Network equipment providing an IPTV service according to a second aspect of the present invention includes a channel receiving unit for receiving traffic through at least one monitoring port among a plurality of ports; and a traffic transmission unit for transmitting information on the traffic volume received through the at least one monitoring port to a monitoring server, based on the information on the traffic volume, whether or not there is an abnormality in the IPTV service in the network equipment. can be judged

A monitoring server providing an IPTV service according to a third aspect of the present invention includes a monitoring port allocator allocating at least one of a plurality of ports of network equipment providing the IPTV service as a monitoring port; a traffic volume receiving unit receiving information on the traffic volume received by the at least one monitoring port from the network equipment; and an abnormality determination unit for determining whether or not the IPTV service in the network equipment has an abnormality based on the information on the amount of traffic, and a channel for receiving traffic can be received through the at least one monitoring port.

The above-described means for solving the problems is only illustrative and should not be construed as limiting the present invention. In addition to the exemplary embodiments described above, there may be additional embodiments described in the drawings and detailed description.

According to any one of the above-described problem solving means of the present invention, the present invention allocates at least one of a plurality of ports of network equipment providing IPTV service as a monitoring port, and the amount of traffic received in the allocated at least one monitoring port It is possible to determine whether there is an abnormality in the IPTV service in the network equipment based on the information about.

Through this, the present invention can implement service-oriented network monitoring reflecting customer sensitivity of the IPTV service beyond the conventional system-oriented network monitoring.

In addition, the present invention can quickly determine whether or not there is a failure by recognizing in advance whether or not there is an abnormality in the IPTV service before a service complaint from a customer is received.

In addition, the present invention can determine whether there is an abnormality in the service on the network path without directly checking the IPTV video data, set the total amount of multicast traffic of each network equipment to be the same, and count the number of quality information of the set-top box. By providing a safe environment, network operators can quickly determine failures and take action.

In addition, since the present invention can recognize the presence or absence of an IPTV service failure in advance before service complaints from customers are received, rapid failover is possible and equipment failure time is reduced (eg, from 20 minutes to 7 minutes, 65 %) and can provide the effect of reducing the number of service complaints.

1 is a configuration diagram of a system for determining whether an IPTV service is abnormal according to an embodiment of the present invention.

Referring to FIG. 1 , the IPTV service abnormality determination system 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, such as a local area network (LAN), a wide area network (WAN), and the Internet (WWW: World Wide Web), wired and wireless data communication network, telephone network, and wired and wireless television communication network. Examples of wireless data communication 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, ultrasonic communication, visible light communication (VLC: Visible Light Communication), LiFi, and the like, but are not limited thereto.

The monitoring server 100 is a server that determines whether or not there is an abnormality in the IPTV service and can compare the amount of multicast traffic received from each of the plurality of network equipments 110 to determine whether there is an abnormality in the IPTV service. Here, the plurality of network devices 110 may be devices that provide an IPTV service to at least one set-top box grouped in each network device 110 .

Specifically, the monitoring server 100 allocates a monitoring port in each of the plurality of network equipment 110, and transmits information on the amount of traffic received from the monitoring port assigned to each of the plurality of network equipment 110 to a plurality of network equipment ( 110) It is possible to determine whether or not an IPTV service is abnormal in each network equipment 110 based on information received from each of the network equipment 110 and traffic volume information for each of the plurality of network equipment 110.

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

For example, the monitoring server 100 counts the number of pieces of quality information whose quality is below a threshold value for each IP assigned to the plurality of set-top boxes 120, and reports whether or not the IPTV service is abnormal based on the count to the network operator. .

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

Figure 2 is a block diagram of the monitoring server 100 shown in Figure 1, according to one embodiment of the present invention.

Referring to FIG. 2 , the monitoring server 100 may include a monitoring port allocation unit 200, a traffic volume receiving unit 210, an abnormality determining unit 220, and a quality monitoring unit 230. Here, 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, description will be made with reference to FIG. 3 together 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 equipments 110 providing the IPTV service to the plurality of set-top boxes 120 as a 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 ports of the second network equipment 114. At least one port 310 of the ports 300 of may be allocated as a monitoring port.

Each of the plurality of network devices 110 may include 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 of a plurality of channels received from the broadcaster server to the set-top box, and the Rx port is a reception port used when receiving a plurality of channels from the broadcaster 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. Through the looped monitoring port 310 , the amount of traffic received in the monitoring port 310 may be collected.

For a moment, referring to 4a to 4c, the traffic monitoring circuit configuration method of the present invention will be described in detail. 4A is a diagram illustrating a conventional traffic monitoring line configuration method.

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

4B is a diagram illustrating a method of configuring a traffic monitoring line according to the present invention. Referring to FIG. 4B, the method of configuring a traffic monitoring line according to the present invention collects multicast traffic by looping through one monitoring port assigned to each network equipment 110 (that is, connecting a Tx port and an Rx port). can

4C is a diagram in which the traffic monitoring line configuration method of the present invention is applied to actual equipment. Referring to FIG. 4C , by looping the Tx port and the Rx port constituting the monitoring ports of the network equipment to make the status of the monitoring server up, it is not necessary to configure a link with the opposing equipment.

Meanwhile, in an existing Ethernet network environment, a port looping processing method may cause a serious risk. Specifically, when the network equipment clearly knows the port of the destination MAC address, it forwards the data packet only to that port, but when it does not know the port of the destination MAC address, or when it must be forwarded to all ports due to the nature of the MAC address, the receiving port Floods data packets to all ports except for

Due to the operating characteristics of these network devices, if a looping network is configured between ports, a broadcasting storming phenomenon in which data packets are repeatedly transmitted between ports indefinitely may occur, which is It increases the load, and the network equipment also becomes CPU overloaded and there is a risk of losing network functions.

In order to eliminate the cause of such a broadcast storming phenomenon, the present invention applies a filter that drops data packets received from the looped Rx port to the monitoring server, thereby configuring the port for general service differently. Through this, the Rx port in the monitoring port can drop all data packets received from the Tx port to block the broadcasting storming phenomenon in advance.

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

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

Each of the plurality of network devices 110 may receive a plurality of the same preset traffic reception channels from the broadcasting company server. For example, each of the first network equipment 112 and the second network equipment 114 transmits a plurality of predetermined over-the-air channels through the monitoring port 310 (seven broadcast channels, for example, a KBS channel, an EBS channel, a JTBC channel, MBN channel, etc.) and traffic reception channels including a plurality of control channels (eg, SI-ACAP channel, SI-WEB channel, SI-UHD channel, etc.) can be equally received from the broadcaster server.

On the other hand, when the traffic volume is collected from each monitoring port 310 of the plurality of network equipment 110, 11 Mbps of bandwidth is consumed per Full HD-class channel, thereby minimizing bandwidth consumption and improving the nationwide IPTV service. IGMP static-join can be set for a major popular airwaves channel among a plurality of airwaves channels in order to determine presence or absence.

The monitoring ports 310 of the plurality of network devices 110 may receive a plurality of predetermined over-the-air channels transmitted by multicast from a broadcasting company server in an IGMP static-join method. Since the plurality of network equipments 110 use the IGMP static-join method, there is no need to perform unnecessary stream processing by joining a plurality of airwave channels one by one, and waste of CPU resources can be minimized, thereby providing smooth IPTV service. .

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

The traffic volume receiving unit 210 may receive information on the traffic volume from each of the plurality of network devices 110 using a simple network management protocol (SNMP) protocol. For example, the traffic volume receiving unit 210 receives information about 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, and It is possible to receive information about the traffic volume of a channel for receiving traffic received from the monitoring port 310 of the second network equipment 114 from the second network equipment 114 .

The presence/absence determination unit 220 may determine whether or not there is an abnormality in the IPTV service in the plurality of network equipments 110 based on the information on the amount of traffic. 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. Thus, it is possible to determine whether or not 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 determines the first If it can be determined that the IPTV service in the network equipment 112 and the network equipment 114 is normal, and the traffic volumes in the first network equipment 112 and the second network equipment 114 are different from each other, the abnormality determining unit In step 220, it may be determined that there is a problem with the IPTV service of the network equipment having a small amount of traffic.

Hereinafter, description will be made with reference to FIGS. 2 and 5 together. Referring to FIGS. 2 and 5 , the quality monitoring unit 230 uses quality information 500 transmitted from each of the plurality of set-top boxes 120 to the quality control server 130 to determine the quality of each set-top box 120. The quality of IPTV service can be monitored.

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

The filter unit 232 may filter a packet to be analyzed among packets for quality information. For example, the filter unit 232 first filters analysis target packets from packets for quality information, and then, from the analysis target packets, the filter unit 232 filters two kinds of quality-related error packets (eg, 'channel black packet' and 'screen tearing packet'). ) and two types of network error packets (eg, 'SI channel join failure packet' and 'unbound join failure packet') may be filtered through secondary filtering.

For example, the quality monitoring unit 230 aggregates the number of set-top boxes that have transmitted quality information indicating direct service abnormalities such as 'black screen' and 'screen disconnection' among the quality information included in the SNMP trap message in real time, occurrence can be detected.

For example, the quality monitoring unit 230 may count the number of IPs of set-top boxes that have transmitted type 2 quality-related error packets or network error packets in real time. At this time, IP information about the set-top box that has transmitted the Type 2 quality-related error packets or the Type 2 network error packets counted above the threshold 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, Configuration, and Protocol) server (not shown) to provide network block and accommodating equipment information to which a set-top box of poor quality belongs, thereby preventing network failure due to network abnormalities. It can provide information to respond immediately to IPTV service failures. Here, a DHCP server (not shown) is disposed for each primary node in each region and allocates an IP to each set-top box 120 providing IPTV service. At this time, the DHCP server (not shown) stores IP block information to be allocated to each set-top box 120, a service identifier, and a DHCP poll name for distinguishing end 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, thereby providing information that can be used to cope with failure of the set-top box over the network. It can be provided to the administrator terminal.

On the other hand, those skilled in the art, each of the monitoring port allocation unit 200, the traffic volume receiving unit 210, the presence or absence determination unit 220, the quality monitoring unit 230, and the filter unit 232 are separately implemented, or among them It will be fully understood that one or more may be implemented in an integrated manner.

6 is a flowchart illustrating a method for 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 step S601, the monitoring server 100 may allocate at least one of a plurality of ports of network equipment providing an IPTV service as a monitoring port. At this time, a predetermined channel for receiving traffic may be received through at least one monitoring port.

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

In step S605, the monitoring server 100 may determine whether or not there is an abnormality in the IPTV service in the network equipment based on the information on the amount of traffic.

In the above description, steps S601 to S605 may be further divided into additional steps or combined into fewer steps, depending on the implementation of the present invention. Also, some steps may be omitted if necessary, and the order of steps may be changed.

FIG. 7 is a block diagram of the first network equipment 112 shown in FIG. 3 according to one embodiment of the present invention.

Referring to FIG. 7 , the first network equipment 112 may include a channel receiver 700 for receiving traffic, a traffic transmission unit 710, and a mirroring unit 720. Here, the channel receiver 700 for receiving traffic may include a filter unit 702 . However, the first network equipment 100 shown in FIG. 7 is only one implementation example of the present invention, and various modifications are possible based on the components shown in FIG. 7 .

The channel receiving unit 700 for receiving traffic may receive a channel for receiving traffic 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 of a plurality of channels received from a broadcasting company server to at least one set-top box, and the Rx port is a receiving port used when receiving a plurality of channels from a broadcasting company server. At this time, the Tx port and the Rx port of the monitoring port are looped so that the traffic amount for the channel for receiving traffic can be collected.

The channel receiving unit 700 for receiving traffic may receive a plurality of predetermined over-the-air channels through the monitoring port 310 in an IGMP static-join manner. For example, the channel reception unit 700 for receiving traffic receives a plurality of preset airwave channels transmitted by multicast from a broadcasting company server in an IGMP static-join method, thereby joining a plurality of airwave channels one by one to perform unnecessary stream processing. Since there is no CPU resource waste and the waste of CPU resources can be minimized, smooth IPTV service can be provided.

The filter unit 702 may drop packets received from the looped Rx port. Specifically, in order to prevent a broadcast storming phenomenon that may occur due to looping between the Tx port and the Rx port of the monitoring port 310, the filter unit 702 filters packets received from the Rx port of the monitoring port. Drops can be processed. Here, the broadcasting storming phenomenon refers to a phenomenon in which data packets are transmitted indefinitely and repeatedly between ports when a looping network is configured between ports, resulting in overload of network equipment and loss of network functions.

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

The traffic amount transmission unit 710 may transmit information about the amount of traffic received through the monitoring port 310 to the monitoring server 100 . Here, the monitoring server 100 may determine whether or not the IPTV service in the first network equipment 112 is abnormal based on the information on the amount of traffic.

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

Meanwhile, for those skilled in the art, each of the channel receiving unit 700 for receiving traffic, the filtering unit 702, the traffic transmission unit 710, and the mirroring unit 720 may be separately implemented, or one or more of them may be integrated and implemented.
