Abstract
Description
Technical Field
[0001] The present application relates to the field of computers, and in particular to a dual-optical port network card with a Bypass function. Background Art
[0002] Network security devices are generally used between two or more networks, such as between an intranet and an extranet. The application program in the network security device will analyze the network packets passing through it to determine whether there are any threats. After processing, the packets will be forwarded according to certain routing rules. If the network security device fails, such as power outage or crash, all network segments connected to the device will lose contact with each other. At this time, if the networks are required to be connected to each other, Bypass must be used.
[0003] Bypass, or the bypass function, allows two networks to be physically connected directly without passing through the network security device system through a specific trigger state (power off or crash). Therefore, with Bypass, when the network security device fails, the networks connected to this device can still be connected to each other. Of course, at this time, the network device will no longer process the packets in the network.
[0004] Currently, high-bandwidth bypass network cards are mainly implemented through optical bypass, which is usually used for multiplexing and distribution of optical signals to achieve flexible optical network topology. In a fiber optic network, optical signals can be transmitted through different optical devices and optical paths. When a device or path fails or requires maintenance, optical bypass can bypass the optical signal around the device or path, allowing it to continue to be transmitted to the target device or path, thereby ensuring network connectivity.
[0005] With the development of technology, the data traffic of access network devices is increasing, and the bandwidth requirements for bypass network cards are increasing accordingly.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0034] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.
[0035] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.
[0036] In addition, the terms "installed", "set", "provided with", "connected", "connected", and "socketed" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0037] By setting Bypass in the network security device, when the network security device fails, the network segments on the network security device will not be exercised and the networks will remain connected to each other.
[0038] In order to avoid single point failure of the product as a serial product, when the device is powered off or crashes, the user's network cannot be unavailable due to the unavailability of the serial product. The hardware bypass function is already a necessary function for flow control products. When the device is powered off or crashes, the internal and external ports can be directly physically connected to form a network cable, so that the user's data traffic can pass directly through the device without being affected by the current status of the device itself.
[0039] When the power is off, the relay loses power and connects the switch to the line connected to the network port below, so the two ports become one physical line, which is equivalent to a short circuit between the two ports. When the power is restored, the relay connects the switch to the line connected to its own system, so they become two independent network ports. In this way, network interruption can be avoided when the power is off.
[0040] In the prior art, high-bandwidth bypass network cards are mainly implemented through optical bypass, which is usually used for multiplexing and distribution of optical signals to achieve flexible optical network topology. When a device or path fails or needs maintenance, the optical bypass can bypass the optical signal around the device or path so that it can continue to be transmitted to the target device or path, thereby ensuring the connectivity of the network. With the development of technology, the data traffic of access network devices is increasing, and the bandwidth requirements for bypass network cards are increasing accordingly. The highest bandwidth of common bypass network cards on the market is only 40Gb, which cannot meet the needs of high data throughput network devices. Therefore, the bypass network cards in the prior art have the problem of being difficult to meet the needs of high data throughput network devices.
