In the present invention, a passive optical communication network management system (NMS) capable of establishing an internal network of schools, government offices, etc., and controlling and controlling wired and wireless devices on PONs will be described.

Here, the PON method configures the network with passive devices (passive) rather than active devices (active). In particular, in a PON network, one core can be divided into multiple parts and used. For reference, light travels with vibration and wavelength, and if a vibration margin of about 28 decibels is applied to light, one core can be divided into about 32 pieces. This PON method is called a passive element by dividing the light source without electric power, and if a mirror is reflected on the divided light source using the prism principle, it can be divided into about 32 and one core optical cable can be branched into 32 cores. This can be used to connect classrooms of 32 classes in a computer room of a school with minimal optical wiring, and a device that connects optical cables wired in this way is an optical multiplexing device. At this time, optical multiplexing is used in the same sense as FTTH (Fiber To The Home) and PON.

The PON network, which is significantly different from the Ethernet network, has two main characteristics. First, it has a point-to-multiplex network structure that connects 32 points with one core, and second, it transmits data, voice, and video with one light source. It is to do multiple services that do.

The PON network uses a transmission technology called Time Division Multiplexing (TDMA) to transmit a large amount of traffic to one light source, and uses different data transmission paths, that is, different wavelength bands. With this transmission technology, the speed of the downstream sending data from the computer room to the classroom is about 2.5 Gbps, and the speed of the upstream sending data up from the classroom to the computer room is about 1.25 Gbps. The standardized standard is called G-PON. The standard for transmitting at a speed of about 10 Gbps is called XGS-PON. All of these communication specifications are defined as standards, and the standards for PON networks are managed by the ITU.

In the present invention, an internal network of an optical network is constructed using the PON technology, and wired/wireless devices on the PON are controlled and controlled.

Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the same reference numerals are used for the same components, and only different parts are mainly described so as not to overlap as much as possible for clarity.

It is a diagram showing the detailed network configuration of the passive optical communication network management system according to another embodiment of the present invention.

1 to 3, the passive optical communication network management system according to an embodiment of the present invention builds a mediation network between a central control system and government offices 200 including schools through an SDN mediation module 100. can

Specifically, government offices 200 including schools may construct an internal network using the optical multiplexing device 300 in a PON manner.

Here, the optical multiplexing device 300 is disposed in a computer room, and is connected to a firewall 410 provided by a telecommunications company to form a network at the upper end, and an optical transmitter 310 that transmits light sources to each branch point at the lower end, An optical splitter 320 disposed at the branch point (EPS room) and diverging light sources transmitted from the computer room at a set ratio or number, and disposed in each classroom and wired with the optical splitter 320 to receive the branched light sources An optical receiver 330 may be included.

The optical transmitter 310 includes a network terminal card that converts PON to Ethernet, and when connected to the firewall 410 provided by the telecommunications company via the security switch 420 using the network link card, four network can be formed. Through this, in the school network, it is possible to build 4 networks with 1 core optical cable in each classroom in the school.

In addition, the optical transmitter 310 may include an optical cable aggregation card (Line Terminal Card) for aggregating optical cables, and may aggregate 16 optical distributors 320 at the bottom using 16 ports of the optical cable aggregation card. At this time, 16 ports of the optical cable aggregation card can be used by upgrading to 10G as combo ports. Through this, in the campus network, 512 optical receivers 330 can be connected with optical cables.

The optical splitter 320 can branch light sources received through 4-core optical cables wired from the computer room to each branch point, usually EPS (Electrical Piping Shaft), at a ratio of 1:32. Here, one core of the 4-core optical cable may be directly connected to the optical distributor 320, and the remaining 3 cores may be fused with a reserve line.

The optical receiver 330 may be connected to the optical distributor 320 through a 2-core optical cable wired from each branch point to each classroom. At this time, one core of the two-core optical cable may be directly connected to the optical receiver 330 of each classroom, and the remaining one core may be fused with a spare line. In this regard, the optical receiver 330 may include a built-in 2-port Fiber Distribution Frame (FDF) and an optical receiving board. At this time, the optical distribution box may connect one core of the two core optical cables descending from the optical distributor 320 to the optical receiving board, and fuse the remaining one core with a spare line.

In addition, the optical receiver 330 is equipped with ONT firmware to convert the data of the light source received through the optical splitter 320 into an Ethernet packet, and maps to an Ethernet port as a user interface can make it

In particular, when the optical receiver 330 is installed in a school, it may be connected to the optical splitter 320 in three forms (types) according to the characteristics of classrooms in the school. In this regard, the optical receiver 330 is disposed in the general classroom to receive the light source coming down from the EPS room, which is a branch point, at the top, and connects at least one of the computer 340 and the wireless AP 350 in the classroom at the bottom. A first-type optical receiver for 10G, a second-type optical receiver disposed in an administrative office or teacher's office where a large number of users work, and a third-type optical receiver for 10G disposed in a computer room or multimedia room where a large amount of traffic occurs. can In addition, the optical receiver 330 may include a user interface for providing communication between the optical receivers 330 through the optical splitter 320 .

The first type optical receiver has four Ethernet ports and can connect four terminals. At this time, the four Ethernet ports may be used separately to correspond to each of the work network 510, the education network 520, the wireless network 530, and the telephone network in the campus network of the school. In addition, three of the four Ethernet ports can supply power so that the wireless AP or IP phone can be used without a separate power adapter.

In addition, the first type optical receiver may prohibit the use of an Ethernet port to which a terminal is not connected, that is, an Ethernet port that is not in use by using a port shutdown function. In addition, the first-type optical receiver can variably change the purpose or function of the Ethernet port in consideration of the fact that the purpose of the classroom may vary from year to year, the consistency of the network configuration throughout the school, and the convenience of network management. For example, the first type optical receiver can change the purpose or function of an Ethernet port for the purpose of constructing a work network by connecting three terminals for teachers or eliminating an educational network by connecting two wireless APs 350 . The first type optical receiver is an available port disposed outside the enclosure, and may include 1 port of Power over Ethernet (Non-PoE) for business network, 1 port of PoE for education network, 1 port for PoE for wireless network, and 1 port for PoE for telephone network.

The second type optical receiver has a built-in 8-port hub, and when connected to an outlet on a classroom wall or a system box on the floor, the number of ports that can connect terminals can be increased up to 16. A teacher's office that needs to connect more than 16 terminals configures a hub terminal box after arranging the first type optical receiver. The hub terminal box has a 24-port switching hub and a patch panel built in. The ports expanded by using the hub terminal box can be connected to terminals such as computers, laptops, multifunction devices, and IP phones through outlets on the walls or system boxes on the floor.

Here, the second type optical receiver has a 1G user interface to communicate with an aggregation network composed of a business network, an education network, a wireless network, and a telephone network, and can include two 8-port hubs to connect more terminals. For example, the office network user interface expands the number of ports with a built-in 8-port hub for teachers, and then is mapped with ports of the office network outside the enclosure to connect up to 7 terminals such as teachers' computers, laptops, and multifunction devices. In this case, one terminal may be directly connected to a port protruding from the outside of the enclosure, and six terminals may be connected to the inside of the enclosure. In addition, the telephone network user interface is mapped with telephone network ports outside the enclosure after expanding the number of ports to the built-in 8-port hub for telephones, allowing up to 7 IP phones to be connected. At this time, one phone can be directly connected to a port protruding from the outside of the enclosure, and six phones can be connected to the inside of the enclosure. The second type optical receiver is an available port disposed outside the enclosure, and may include 1 port of Power over Ethernet (Non-PoE) for business network, 1 port of PoE for education network, 1 port for PoE for wireless network, and 1 port for PoE for telephone network.

The third type optical receiver is made for 10G capable of handling large-capacity traffic, and after adding ports to the 10G switching hub of the hub terminal box, terminals such as computers can be connected through the system box on the floor. At this time, the phone is preferably directly connected to the third type optical receiver.

Here, the third type optical receiver has a 10G user interface to communicate with the convergence network, and can include two 8-port hubs to connect more terminals. In this case, the 10G user interface may build a 10G network by mapping with one of the business network, education network, wireless network, and telephone network. For example, after mapping a 10G user interface with an educational network, a computer room can be built as a 10G network by uplinking a 10G switching hub with a 10G Ethernet port protruding from the enclosure. For another example, if a wireless network is established by connecting a Wi-Fi wireless AP to a 10G Ethernet port, a large amount of wireless traffic can be processed.

In the third type optical receiver, the work network user interface is mapped with the Ethernet port for teachers protruding from the outside of the enclosure, and there are 6 extra ports inside the enclosure, so that a total of 7 teacher terminals can be connected, and the telephone network user interface is built-in 8 ports. After expanding the number of ports with a port hub, it is mapped with PoE ports outside the enclosure so that a total of 7 IP phones can be connected without a power adapter. In addition, the student network user interface may be mapped with a student network Ethernet port protruding outside the enclosure, and the wireless network user interface may be matched with a Wi-Fi port protruding outside the enclosure. A total of 17 terminals can be connected to the third type optical receiver for 10G.

However, the phone in each classroom is connected to the telephone switching facility (IP-PBX, IP-Phone) in the computer room, so the network can be physically separated from the PON.

On the other hand, since the network environment is not common due to the characteristics of the campus network, the teacher's office and the administrative office must communicate, and the computer room data and the administrative office data must be separated. Accordingly, even in the PON network, the basic network configuration utilizes a virtual LAN (VLAN), and each of the business network 510, education network 520, and wireless network 530 is assigned a unique virtual LAN identification information (VLAN ID). can be taken and bound. For example, a virtual network may be constructed by grouping the business network 510 with VLAN ID 10, the education network 520 with VLAN ID 20, and the wireless network 530 with VLAN ID 30.

In particular, a virtual LAN (VLAN) of an Ethernet network is based on a physical port, whereas a virtual LAN (VLAN) of a PON network may be set based on a virtual port.

The network link card of the optical transmitter 310 can configure a network by being connected to a firewall through four Ethernet ports. The virtual LAN identification information (VLAN ID) of the network link card (NT card) connected to the upper Ethernet network is mapped with the optical cable aggregation card (LT card) that aggregates the light source of the PON network, and the optical transmitter 310 connects the network link Virtual LAN (VLAN) information (setting value) of the card (NT card) can be transmitted to all optical receivers 330 that are aggregated.

The optical receiver 330 may complete a network by mapping the received virtual LAN identification information (VLAN ID) with a user interface, that is, an Ethernet port.

If data is transmitted from the administrative office to the administrative office, packets generated in the administrative office may move to the optical transmitter 310 along the virtual LAN identification information (VLAN ID). In addition, a packet to communicate with other virtual LAN identification information (VLAN ID) or to go out to the Internet may move to the firewall along the virtual LAN identification information (VLAN ID) mapped in the optical transmitter 310 . In this way, communication with other virtual LAN identification information (VLAN ID) is blocked by the security policy of the firewall, and network configuration can be completed. In addition, optical receivers 330 having the same virtual LAN identification information (VLAN ID) can communicate with each other.

Again, in the case of sending data from the administrative office to the office, describing the communication process between the optical receivers 330, the packets generated in the administrative office move to the optical transmitter 310, and the packets from the optical transmitter 310 are aggregated. may be transmitted to all optical receivers 330 therein. At this time, all the optical receivers 330 receive the signal, but since the optical transmitter 310 encrypts and transmits the information of the optical receiver 330 to transmit data together with the packet, the optical receiver 330 that can respond to this is determined Here, the responding optical receiver 330 may generate a GEM (G-PON Encapsulation Methode) port, which is a logical port, to map one light source to N user interfaces (N is a natural number equal to or greater than 2). In addition, the responding optical receiver 330 may map the GEM port with virtual LAN identification information (VLAN ID) of the Ethernet port. At this time, the GEM encapsulates and has important information among frames of Ethernet packets. The optical receiver 330 decrypts the encrypted packet contained in the capsule, and then checks the MAC address of the destination among the packets and transmits the packet to the office, which is the destination.

Referring to the above-described method of moving packets, looking at the data flow of the business network as an example, packets generated in the administrative office move to the business network, LAN 1 port of the optical receiver 330 connected to the connector (outlet). In addition, packets from the administrative office pass through the optical splitter 320 on the connected optical cable, reach the optical transmitter 310 of the computer room, and move to the work network port of the firewall by taking the VLAN ID 10 of the optical transmitter 310. At this time, the firewall transmits the packet going to the Internet to the outside, and the data to be transmitted to the office as a packet for internal communication is encapsulated with the source and destination information encrypted and moved to the office. The packets from the administrative office are transmitted to the terminal connected to the system box after going through the switching hub uplinked to the office network and LAN 1 port of the office.

In addition, referring to the aforementioned method of moving packets, looking at the education network data flow as an example, the packets generated in the computer room move along the VLAN ID 20 along the education network and PoE 1 port of the optical receiver 330.

In addition, referring to the aforementioned method of moving packets, looking at the data flow of the wireless network as an example, packets generated from the tablet move along the VLAN ID 30 via the wireless network and the PoE 2 port.

In addition, referring to the aforementioned method of moving packets, looking at the telephone network data flow as an example, the telephone network packets from the administrative office take the PoE 3 port of the optical receiver 330 and move to the telephone switching facility (IP-PBX) and then to the VLAN Move along ID 40. Conversely, the signal from the internally switched phone is transmitted to the office via VLAN ID 40 and PoE 3 port.

Meanwhile, the passive optical communication network management system 10 according to the present invention may further connect the wireless control network 620 to the internal network of the government office 200 built in a passive optical communication network (PON) method. Here, the wireless control network 620 controls and controls the passive optical communication network management system 10 by connecting the POE network previously constructed through the PoE 610 to the optical transmitter 310 through the optical receiver 330. can receive

The SDN brokerage module 100 is one of the orchestrator (SDN-O) 110 and the controller (SDN-C) 120 according to the form of the brokerage network in order to build a brokerage network between the central control system and government offices including schools. may contain at least one. Here, the orchestrator (SDN-O) 110 may be in charge of integrated control and control of wired and wireless devices (resources) on the PON network. In addition, the controller (SDN-C) 120 directly controls wired/wireless devices (resources) on the PON network and may provide information to the user through the orchestrator (SDN-O) 110.

As such, the SDN mediation module 100 secures failure management for failure detection, configuration management for device status, account management for usage status, performance management for usage analysis, and leakage prevention through integrated wired and wireless control and control. It can perform monitoring and management functions including management. For example, the SDN mediation module 100 can perform traffic separation, isolation, and recovery for failure management, modify, delete, and add settings for configuration management, and use values for account management.
