Description

Technical Field

[0001] This invention belongs to the field of communication technology, specifically relating to a centralized monitoring system and method for computer rooms based on EPON networking. Background Technology

[0002] When planning the deployment of communication systems, the principle of proximity is typically followed. Aggregation sites are established at user convergence points, and a single communication system is deployed to cover surrounding users, which can reduce the cost of installation at individual homes to some extent. During the deployment of the communication system, a supporting network management server and network management terminals are also deployed simultaneously for the management of the entire system and daily maintenance operations. Maintenance personnel operate on the network management terminals, transmitting maintenance data to the network management server, which then transmits it to the continuously running front-end devices. Due to the distributed deployment of the system, the network management server and terminals are also deployed in a distributed manner.

[0003] Initially, each site had personnel on-site to perform daily maintenance. However, in recent years, with the continuous improvement of personnel efficiency, the requirements for network centralization have also increased. The previously dispersed systems now need to be centrally monitored and operated in the central control room. Traditional solutions include: 1) using point-to-point direct fiber optic transceivers, where one transceiver is installed in each remote site's computer room and the central control room, interconnected by fiber optic cables. The transceivers convert optical signals to electrical signals, connecting the client and server respectively, thus achieving communication. Due to the point-to-point method, the central control center has a large number of fiber optic transceivers. 2) using Layer 2 data switches / hubs to form a dedicated data exchange network. Each remote site deploys an access switch (usually a simple, non-remotely managed type), and the central control center deploys an aggregation switch. The access switches and aggregation switch are interconnected by fiber optic cables to form a dedicated data network. The dispersed network management servers, system front-ends, and network management terminals connect to this data network for interconnection. The above solutions have the following problems:

[0004] 1. Although using fiber optic transceivers for networking is logically very simple, it will consume a large amount of backbone fiber optic resources due to point-to-point transmission. In addition, a large number of fiber optic transceivers need to be installed in the central control center, and the power supply and placement issues increase the difficulty of data center management. Fiber optic transceivers have a high failure rate and are consumables, which will increase the cost of later operation and maintenance.

[0005] 2. While using switches for networking, with only one aggregation switch deployed in the control center for ease of data center management, this approach does not reduce the use of backbone fiber optic resources. Port isolation on the switches is disabled by default, and some low-performance switches lack this feature, posing a network security risk. In later network maintenance, unmanaged switches cannot be remotely logged into to check port status and quickly locate faults. While managed switches allow remote login to check port status, this is often only done after the client malfunctions, by which time the fault has already occurred, directly impacting troubleshooting efficiency. Furthermore, the large number of switch ports, especially for dedicated networks, results in a significant number of idle ports, leading to wasted resources and increased costs.

[0006] EPON (Ethernet Passive Optical Network) is a PON technology based on Ethernet. It employs a point-to-multipoint structure and passive fiber transmission, providing various services over Ethernet. EPON offers advantages such as low cost, high bandwidth, strong scalability, compatibility with existing Ethernet networks, and ease of management. An EPON network consists of three parts: the OLT (Optical Line Terminal) at the central office, the ODN (Passive Optical Network), and the ONU (Optical Network Unit) at the user end. Summary of the Invention

[0007] To address at least some of the aforementioned problems in the existing technology, this invention provides a centralized monitoring system and method for data centers based on EPON networking.

[0008] This invention is implemented as follows:

[0009] In a first aspect, the present invention provides a centralized monitoring system for a data center based on EPON networking, comprising a first optical network unit, an optical splitter, an optical line terminal, and multiple network management clients deployed in a core data center, and a second optical network unit deployed in each peripheral data center. The first optical network unit and the second optical network unit are connected to the optical line terminal via the optical splitter. The first optical network unit is interconnected with the multiple network management clients, and the second optical network unit is interconnected with each server in the corresponding peripheral data center. Each network management client is used to access the servers in the core data center and the peripheral data centers, respectively. The optical line terminal is interconnected with the servers in the core data center via the network management network.

[0010] Furthermore, it also includes a switch management computer located in the core computer room and a switch located in the peripheral computer room. The switch management computer is interconnected with the first optical network unit, and the switch is interconnected with the second optical network unit in the corresponding peripheral computer room.

[0011] Secondly, the present invention also provides a centralized monitoring method for a data center based on EPON networking as described above, comprising the following steps:

[0012] (1) Install a first optical network unit in the core computer room and a second optical network unit in the peripheral computer room. Connect the first optical network unit and the second optical network unit to the optical line terminal in the core computer room through an optical splitter. Connect the first optical network unit to multiple network management clients. Connect the second optical network unit to each server in the corresponding peripheral computer room. Connect the optical line terminal to the server in the core computer room through the network management network.

[0013] (2) Register the first optical network unit and the second optical network unit on the optical line terminal and configure the remote management addresses of the first optical network unit and the second optical network unit;

[0014] (3) Configure virtual local area network transparent data between the optical line terminal and the first optical network unit and between the optical line terminal and the second optical network unit, and transmit the virtual local area network management data of the optical line terminal to the first optical network unit and the second optical network unit.

[0015] (4) Configure the corresponding IP address of the server accessed on each network management client;

[0016] (5) Manage the network of each server through the network management client.

[0017] Furthermore, step (3) is followed by setting up a three-layer virtual gateway on the optical line terminal.

[0018] Furthermore, step (4) is followed by: pinging the virtual gateway address and the server address of the optical line terminal segment by segment to verify connectivity.

[0019] Furthermore, step (5) specifically includes:

[0020] Log in to the network management system via the network management client or remotely log in to the server to manage the network.

[0021] Furthermore, it also includes centralized monitoring through an external network management system, with the following steps:

[0022] (1) Connect the ETH port of the corresponding peripheral equipment room switch through the network port of the second optical network unit;

[0023] (2) Connect the switch management computer through the network port of the first optical network unit;

[0024] (3) Remotely control the switch through the switch management computer to perform routine maintenance.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The centralized monitoring and monitoring method for data centers based on EPON networking provided by this invention is based on EPON networking. The OLT-ODN-ONU network structure is simple and intuitive, and there will be no network loops. The default isolation performance of the physical ports of the optical network unit (ONU) further improves the reliability of network transmission.

[0027] 2. Optical splitter (ODN) can maximize the conservation of backbone optical cable resources and save costs;

[0028] 3. The dedicated EPON network management system can monitor the status of PON ports and optical network units (ONUs) in real time. If an alarm occurs, the network management platform will immediately issue an audible alarm, shortening the fault response time. The system segments the optical line terminal (OLT) and optical network unit (ONU) and judges the connectivity of each segment one by one, thereby quickly locating the fault point and improving the work efficiency of maintenance personnel.

[0029] 4. For new network management systems, only one or two optical network units (ONUs) need to be added. The ONUs register with the optical line terminal (OLT) through the optical splitter (ODN) network, which can easily enable communication between devices connected to the ONUs and facilitate expansion.

[0030] 5. This invention utilizes EPON networking. Due to the wide coverage of the optical splitter ODN network and the flexibility of the optical network unit ONU deployment, and with the configuration of corresponding security access control policies, maintenance personnel can access the servers in the core computer room from information points near their homes or even at home via a client on a mobile laptop, without having to go to the computer room, thus creating conditions for remote operation and maintenance.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figure 1As shown, this embodiment of the invention provides a centralized monitoring system for a data center based on EPON networking, which is applied to a core data center and at least one peripheral data center. Each core data center and peripheral data center is equipped with at least one server. In this embodiment, there is only one peripheral data center, and the core data center is equipped with two servers, namely server 1 and server 2, and the peripheral data center is equipped with two servers, namely server 3 and server 4. The monitoring system includes a first optical network unit (ONU1), an optical splitter (ODN), an optical line terminal (OLT), and four network management clients, namely network management client 1, network management client 2, network management client 3, and network management client 4, all located in the core computer room. Each network management client is used to access servers in the core computer room and peripheral computer rooms. The system also includes a second optical network unit (ONU2) located in each peripheral computer room, with one ONU2 in each peripheral computer room. The first ONU1 and the second ONU2 are connected to the OLT via the optical splitter (ODN). The first ONU1 is interconnected with multiple network management clients, and the second ONU2 is interconnected with servers in the corresponding peripheral computer room. The OLT is interconnected with servers in the core computer room via the network management network.

[0036] This embodiment interconnects the network management servers deployed in distributed peripheral equipment rooms with the network management clients deployed in the core equipment room for centralized monitoring. Optical splitter network (ODN) saves backbone fiber optic cable resources, significantly reducing networking costs; the optical network unit (ONU) offers a variety of device types, providing 1-24 interfaces, allowing users to flexibly choose according to their application scenarios, further reducing networking costs; the PON ports of the ODN and the ports of the ONUs are physically isolated by default, ensuring network security; in later maintenance, the EPON network management system can intuitively obtain the real-time status of each ONU and simultaneously push audible and visual alarms, enabling maintenance personnel to promptly detect and respond, greatly improving efficiency.

[0037] This invention also provides a centralized monitoring system and method for data centers based on EPON networking, as described in the above embodiments, comprising the following steps:

[0038] (1) Install the first optical network unit ONU1 in the core computer room and the second optical network unit ONU2 in the peripheral computer room. Connect the first optical network unit ONU1 and the second optical network unit ONU2 to the optical line terminal (OLT) in the core computer room through the optical splitter ODN. Connect the first optical network unit ONU1 to multiple network management clients. Connect the second optical network unit ONU2 to each server in the corresponding peripheral computer room. Connect the optical line terminal (OLT) to the server in the core computer room through the network management network to complete the physical connection.

[0040] (3) Configure virtual local area network transparent data between the optical line terminal OLT and the first optical network unit ONU1 and between the optical line terminal OLT and the second optical network unit ONU2, and transmit the virtual local area network management data of the optical line terminal OLT to the first optical network unit ONU1 and the second optical network unit ONU2.

[0041] (4) Configure the corresponding IP address of the server accessed on each network management client;

[0042] (5) Manage the network of each server through the network management client.

[0043] At this point, EPON networking has enabled communication between the network management server and network management client, which are respectively connected to the two optical network units (ONUs). All data configurations made by operation and maintenance personnel on the network management client are synchronized to the server side.

[0044] Preferably, after step (3), the method further includes: setting up a three-layer virtual gateway on the optical line terminal (OLT) so that three-layer interconnection can be achieved between the OLT and the first optical network unit (ONU1) and between the OLT and the second optical network unit (ONU2) under the condition of default two-layer port isolation.

[0045] More preferably, after step (4), the method further includes: pinging the virtual gateway address and the server address of the optical line terminal segment by segment to verify connectivity until the ping is successful, thereby enhancing reliability.

[0046] Furthermore, step (5) specifically includes: logging into the network management system of the network management client or remote desktop login server for network management, which is convenient.

[0047] The following is combined with Figure 1 This embodiment provides a detailed description of the centralized monitoring system and method for data centers based on EPON networking.

[0048] like Figure 1As shown, there are two servers in the core data center, namely Server 1 and Server 2, and two servers in the peripheral data center, namely Server 3 and Server 4. Four network management clients are deployed centrally in the core data center, requiring access to each of the four servers. The four network management clients are designated as Network Management Client 1, Network Management Client 2, Network Management Client 3, and Network Management Client 4. Server 1 uses the 192.168.10 network segment, Server 2 uses the 192.168.20 network segment, Server 3 uses the 192.168.30 network segment, and Server 4 uses the 192.168.40 network segment. The specific implementation steps are as follows:

The first optical network unit (ONU1) and the second optical network unit (ONU2) are connected to the optical line terminal (OLT) in the core equipment room through the optical splitter (ODN). Ports 1, 2, 3 and 4 of the first optical network unit (ONU1) are respectively connected to the network management client 1, network management client 2, network management client 3 and network management client 4. The two network ports of the second optical network unit (ONU2) are connected to the server 3 and server 4 through the network management network. The optical line terminal (OLT) is interconnected with the server 1 and server 2 through the network management network.

[0050] (3) Register the first optical network unit ONU1 and the second optical network unit ONU2 on the optical line terminal (OLT) and configure the remote management addresses of the first optical network unit ONU1 and the second optical network unit ONU2.

[0051] (4) Create vlan10, 20, 30 and 40 in the optical line terminal OLT, bind vlan10 and 20 to the PON port, and bind vlan30 and 40 to the uplink port;

[0052] (5) Create VLANs 10, 20, 30, and 40 on the first optical network unit ONU1 and bind them to ports 1, 2, 3, and 4 in sequence. Create VLANs 10 and 20 on the second optical network unit ONU2 and bind them to ports 1 and 2 in sequence.

[0053] (6) Configure virtual gateway vlanif10 on the optical line terminal OLT;

[0054] (7) Configure the corresponding IP address of the server accessed on each of the four network management clients, ping the virtual gateway address of the optical line terminal and the server address segment by segment to verify connectivity.

[0055] (8) Log in to the network management client to manage the network.

[0056] Example 2

[0057] like Figure 2As shown, this embodiment of the invention provides a centralized monitoring system for a data center based on EPON networking. It adds an external data center to the monitoring system of Embodiment 1. The monitoring system of this embodiment also includes a switch management computer located in the core data center and switches located in the external data center. The switch management computer is interconnected with the first optical network unit (ONU1), and the switches are interconnected with the second optical network unit (ONU2) in the corresponding external data center. The switch management computer allows for remote control of the switches, enabling routine maintenance and external network management.

[0058] This invention also provides a centralized monitoring method for a data center based on EPON networking, as described in the above embodiments. Based on the method in Embodiment 1, it adds a method for centralized monitoring via an external network management system. The steps are as follows:

[0059] (1) Connect the ETH port of the corresponding peripheral equipment room switch through the ONU2 network port of the second optical network unit;

[0060] (2) Connect the switch management computer through the network port of the first optical network unit ONU1;

[0061] (3) Remotely control the switch through the switch management computer to perform routine maintenance.

[0062] In summary, the present invention has the following beneficial effects:

[0063] 1. The centralized monitoring system and method for data centers based on EPON networking provided by this invention is based on EPON networking. The OLT-ODN-ONU network structure is simple and intuitive, and there will be no network loops. The default isolation performance of the physical ports of the optical network unit (ONU) further improves the reliability of network transmission.

[0064] 2. Optical splitter (ODN) can maximize the conservation of backbone optical cable resources and save costs;

[0065] 3. The dedicated EPON network management system can monitor the status of PON ports and optical network units (ONUs) in real time. If an alarm occurs, the network management platform will immediately issue an audible alarm, shortening the fault response time. The system segments the optical line terminal (OLT) and optical network unit (ONU) and judges the connectivity of each segment one by one, thereby quickly locating the fault point and improving the work efficiency of maintenance personnel.

[0066] 4. For new network management systems, only one or two optical network units (ONUs) need to be added. The ONUs register with the optical line terminal (OLT) through the optical splitter (ODN) network, which can easily enable communication between devices connected to the ONUs and facilitate expansion.

[0067] 5. Network management networks are typically private networks and inaccessible via the public internet. Even when accessing the internal network from the public internet via a VPN, it's generally impossible to access the private network. Therefore, the traditional method to log in to the network management network server is to go to a data center with the necessary network access. This invention utilizes EPON networking. Due to the wide coverage of the optical splitter ODN network and the flexibility of the optical network unit (ONU) deployment, along with the configuration of appropriate security access control policies, maintenance personnel can access the servers in the core data center from nearby information points or even at home using a client on a mobile laptop, without having to go to the data center, thus creating conditions for remote operation and maintenance.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
