[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0025] like Figure 1-Figure 2 As shown, the network redundancy circuit based on the dual network port chip provided in this embodiment includes a server 1 and multiple switches 2. The server 1 is provided with a dual network port chip 101, the model of the dual network port chip 101 is W6100, and the dual network port chip 101 internally integrates the Ethernet data link layer MAC and the 10Base-T / 10Base-Te / 100Base-TX Ethernet physical layer PHY to improve the adaptability of the circuit. The dual network port chip 101 is provided with two network interface cards NIC102, the network interface card NIC102 corresponds to the switch 2 and establishes a communication connection, and one of the network interface cards NIC102 is set as the main interface, and the other network interface card NIC102 is set as the standby interface. The dual network port chip 101 is an integrated circuit chip with dual network port function, which can support data transmission of two network ports at the same time. This chip uses multiplexing technology to transmit the data of the two network ports through different channels respectively, thereby avoiding data conflicts and improving the efficiency of data transmission.
[0026] The dual network port chip 101 supports two independent network interface cards NIC102, which can be connected to different network devices or subnets respectively, and can achieve a transmission rate of gigabit level to meet the transmission requirements of large-volume data. The server 1 is configured with two dual network port chips 101, each of which is connected to a different switch 2, which allows the other interface to remain connected when a switch 2 or link fails;
[0027] The redundant link 301 includes a redundant protocol 302, which includes a VRRP virtual router redundant protocol, a HSRP hot standby router protocol, and a GLBP gateway load balancing protocol. The VRRP virtual router redundant protocol, the HSRP hot standby router protocol, and the GLBP gateway load balancing protocol are used to share IP addresses between multiple network devices and automatically switch to a backup device when a primary device fails. Multiple protocols are supported to adapt to different network environments and device requirements, and the scope and flexibility of use are improved. The redundant link 301 significantly improves the availability of the network and reduces the service interruption time caused by a single point of failure. It can also be used for load balancing to disperse network traffic to multiple paths and improve the overall network performance. When a primary link fails, the system should be able to automatically detect and switch to a redundant link, and the entire network can still remain operational.
[0028] The switches 2 are connected to each other via a main link 3 or a redundant link 301, and an external network 4 is connected to the switch 2. The network redundancy circuit diagram involves two network devices, which are connected via a redundant link 301 to ensure that the continuity of communication can be maintained in the event of a network failure;
[0029] Further, such as Figure 1 As shown, the redundant link 301 is a physical link or a virtual link, wherein the physical link is an optical fiber or a copper cable, and redundancy is achieved by laying additional physical lines of optical fiber or copper cables. This method is more expensive, but also has the highest reliability. The virtual link is a logical link configured through a VLAN, and a redundant path is logically created using a virtual link or a routing protocol. This method is less expensive, but may be limited by the bandwidth and performance of the physical link;
[0030] Furthermore, if Figure 1 As shown, the dual network port chip 101 includes two network processing circuits 103 and two network interface circuits 104, and the two network interface circuits 104 establish communication connections with two network interface cards NIC102 respectively;
[0031] The two network interface circuits 104 are respectively configured to package and process network signals from network devices, and have a network topology management function to help users simplify the network structure and improve the manageability and performance of the network.
[0032] Furthermore, if Figure 2As shown, the network processing circuit 103 adopts a NE6000 chip, and the network interface circuit 104 includes a network transformer. A detection module 303 is provided on the redundant link 301. The detection module 303 is used to detect the network status. The detection module 303 includes a chip NE555. The chip NE555 is electrically connected to an LED and a speaker. It has data security protection functions such as data encryption and access control to prevent data leakage and illegal access. Once a network failure occurs, an alarm will be directly issued through the LED or speaker on the detection module 303 to improve timeliness.
[0033] like Figure 1-Figure 2 As shown, the principle of the network redundancy circuit based on the dual network port chip provided in this embodiment is as follows:
[0034] The dual network port chip 101 supports two independent network interface cards NIC102, which can be connected to different network devices or subnets respectively, and can achieve a transmission rate of gigabit level to meet the transmission requirements of large-volume data. The server 1 is configured with two dual network port chips 101, each of which is connected to a different switch 2, which allows the other interface to remain connected when a switch 2 or link fails;
[0035] Support multiple protocols to adapt to different network environments and equipment requirements, improve the scope of use and flexibility. Redundant link 301 significantly improves network availability and reduces service interruption time caused by single point failures. It can also be used for load balancing, dispersing network traffic to multiple paths and improving overall network performance. When the main link fails, the system should be able to automatically detect and switch to the redundant link, and the entire network can still remain operational;
[0036] The switches 2 are connected to each other via a main link 3 or a redundant link 301, and an external network 4 is connected to the switch 2. The network redundancy circuit diagram involves two network devices, which are connected via a redundant link 301 to ensure that communication continuity can be maintained in the event of a network failure.
[0037] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
[0038] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
[0039] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
