Problems solved by technology

However, for the EOC system, the management device at the central office cannot know from which terminal device the message is sent to the central management device, so the exact user that caused the loop cannot be determined, and loop detection cannot be realized

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0019] The invention discloses a method for realizing loop detection on EOC equipment, which specifically includes the following steps: the central office management equipment sequentially sets the identifiers of each user terminal, and in the protocol message sent by the central office management equipment Add identifiers for different user terminals. After each user terminal receives a message, through the message filtering mechanism, only the protocol messages that match the identifier of the user terminal are allowed to pass, and other protocol messages are discarded; the authority manages the device When the protocol message returned by the loop is received, the user under which user terminal generates the loop by checking the identifier in the message. The above method enables loop detection to be implemented in all EOC systems, does not require a special EOC chip to id...

Abstract

The invention relates to an EOC (Ethernet Over Coax) system. The invention discloses a method for realizing loop detection on an EOC device. The method comprises the followingconcrete steps that: a central office management device sets an identifier for each user terminal in succession; the identifiers of different user terminals are added in protocol messages sent by the central office management device; after receiving the messages, each user terminal activates a message filter mechanism which only allows the protocol message matched with the identifier of the user terminal to pass, and rejects all the other protocol messages; and when the central office management device receives the protocol message returned by the loop, the identifier in the message is checked so that the user terminal under which the loop is generated can be known. The invention can realize loop detection in all EOC systems and is dispensed with a special EOC chip to identify the source user terminal of the message, the system cost is reduced, and simultaneously, the detection efficiency and the practibility are improved.

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 realizing loop detection on an EOC device. Background technique [0002] EOC is the main technology of the triple play access layer. It consists of 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. [0003] 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 can connect to multiple user devices. User equipment accesses the Internet through the EOC network. [0004] Once a user equipment under a...
