Problems solved by technology
[0002] The network access system is used to connect each user to the metropolitan area network, so that the user can enjoy various services brought by the network. One end of the multiple user switching devices in the network access system is connected to the metropolitan area network switching device , and the other end is connected to a certain number of users to realize the connection between the MAN and the users. With the upgrade of the user network bandwidth, the user switching equipment is gradually moved to a place closer to the user. The MAN switching equipment and the The distance between user switching devices is relatively long. Faced with this situation, there is no mature network access system. If the above-mentioned original tree connection method is continued, due to municipal construction and other reasons, it is likely to cut off the metropolitan area. If the optical fiber between the network transfer device and the user transfer device is used, then all the users connected to the user transfer device will be disconnected from the MAN, resulting in a network disconnection accident. The reliability of the user network is poor, which brings users inconvenient

The invention discloses a network access system. The network access system comprises an annular fiber network, user switching devices connected to a preset number of users respectively, a MAN switching device connected to the MAN, a first data direction management device arranged in the annular fiber network and connected to the MAN switching device, and second data direction management devices arranged in the annular fiber network and connected to the user switching devices in one to one correspondence; and via the second data direction management devices, received user data is transmitted inthe annular fiber network according to the preset direction, and is transmitted to the first data direction management device along a path in the annular fiber network when there is a breakpoint in the annular fiber network. A network outage accident can be avoided even if there is the breakpoint in the annular fiber network, and the reliability of the user network is improved. The invention alsodiscloses a MAN system with the same effect of the network access system.
Description
technical field [0001] The present invention relates to the field of metropolitan area network, in particular to a network access system, and also to a metropolitan area network system. Background technique [0002] The network access system is used to connect each user to the metropolitan area network, so that the user can enjoy various services brought by the network. One end of the multiple user switching devices in the network access system is connected to the metropolitan area network switching device. , the other end is connected with a certain number of users to realize the connection between the metropolitan area network and the user, and with the upgrade of the user's network bandwidth, the user switching equipment is gradually moved to a place closer to the user, and the metropolitan area network switching equipment and The distance between the user's switching devices is long. In this situation, there is no mature network access system. If the above-mentioned orig...
