Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] The present invention discloses a method for restricting learning of MAC addresses at the EOC local end, which specifically includes the following steps: Step 1. The user equipment sends a message to the EOC terminal connected to the user equipment, and the EOC terminal learns the MAC address of the message, and reports The source MAC address in the text data frame is recorded in the MAC address learning table of the EOC terminal, and then the message is sent to the corresponding EOC central office. Such as figure 1 As shown in the typical EOC application scenario structure diag...

Abstract

The invention relates to the technical field of an EOC (Ethernet over Coax) system, and discloses a method for learning EOC local side MAC (Medium / Media Access Control) address restriction. The method comprises the following steps of: judging the source of a message after receiving the message at EOC local side equipment; directly learning the MAC address of the message if the message is transmitted from an EOC terminal; judging whether the message is an error message or not if the message is transmitted from a data network, if so, discarding the message directly, otherwise, learning the MAC address of the message; and after learning the MAC address of the message, transmitting the address according to the destination MAC address of the message. According to the method, error messages are discarded directly, so that wrong learning of the MAC addresses of the error messages is avoided. Messages from the data network are judged, the messages are discarded directly if the messages are error messages, and wrong learning of the MAC addresses of the messages are avoided, so that messages which are correctly transmitted to users can still be accurately sent to users after being received, and the severe network problem that a part of users cannot receive messages within a certain period of time is solved.

Description

technical field [0001] The invention relates to an EOC system, that is, an Ethernet signal transmission technology on a coaxial cable, in particular to a method for learning restriction of an EOC local end MAC address. Background technique [0002] The original text of EOC is "Ethernet over Coax", which is a transmission technology of Ethernet signals on coaxial cables. It is the main technology of the triple play access layer. It consists of three parts: central office management equipment, terminal equipment, and user equipment, which form a two-layer network. Wherein, the central office equipment is connected to the terminal equipment through a coaxial cable, and the terminal equipment is connected to the user equipment through an Ethernet cable. Under normal circumstances, one central office device is usually connected to multiple terminal devices, such as 10 to 32. The terminal devices are placed in the user's home to connect to user devices, and each terminal device c...
