Problems solved by technology

The biggest defect of in-band management is that when the channel fails and is interrupted, neither data information nor management information can be transmitted normally
But in general, the path of remote out-of-band management is physically separated from the path of in-band management, which will undoubtedly directly increase the cost of operators

Embodiment 1

[0026] This embodiment provides a remote out-of-band management method of a communication system. The method mainly uses a head-end device to graft the remote out-of-band management link on the same physical link as the in-band link. The remote out-of-band management Links use a different communication mode than in-band links. In the out-of-band management link in this embodiment, at least the downlink adopts a communication mode with stronger anti-interference, such as a modulation and coding mode.

[0027] The detailed process of the grafting is as follows figure 1 As shown, the out-of-band management data is transmitted to the user end by the physical link after being processed by the out-of-band modulation encoder and the out-of-band transmission power controller; the in-band data is transmitted by the in-band modulation encoder and the in-band power controller After being processed by the rate controller, it is transmitted to the user end by the physical link; the modula...

Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is that: the out-of-band modulation encoder and the in-band modulation encoder are time-division modulation encoders. This embodiment needs to maintain reliable and accurate synchronization between the head-end device and the terminal device. The out-of-band management data packet can only be transmitted in a specific time slot, and the receiving end must reliably identify the preamble sequence of the physical layer, and then manage it in the out-of-band The data slot and the in-band data slot (ie user data slot) use different demodulation and decoding methods to accurately separate the two data streams.

Embodiment 3

[0036]The difference between this embodiment and Embodiments 1 and 2 is that: the transmission power of the remote out-of-band management link is greater than that of the in-band link, and at this time the anti-interference performance of the out-of-band management link is stronger than that of the in-band link , and at the same time, it can better ensure the smooth transmission of out-of-band management data to the client. In addition, the out-of-band management link can also increase the transmission power to enhance anti-interference.

Abstract

The invention discloses a remote out-of-band management method and a remote out-of-band management system for a communication system. The method mainly comprises the following steps of: utilizing head-end equipment to graft a remote out-of-band management link onto a physical link identical with an inband link; and leading the remote out-of-band management link to adopt a communication mode different from a communication mode of the inband link. When the interference of noise in the system is increased, and the inband link is interrupted, with the adoption of the method, control and management information still can be normally transmitted to remote equipment to monitor and debug the remote equipment, and the communication of the inband link can be recovered by setting a communication mode of a new inband link; and moreover, the cost is not increased.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a remote out-of-band management method and system of a communication system. Background technique [0002] The currently used network management methods are basically in-band management, that is, control management information and data information are transmitted through the same channel. The commonly used HPOpenview network management software is a typical in-band management system, in which data information and management information are transmitted through the Ethernet port of the network device. The biggest defect of the in-band management is that: when the channel fails and is interrupted, both data information and management information cannot be transmitted normally. [0003] For example, in a broadband access system, the remote management of user access equipment (such as MODEM) is very important. The communication link corresponding to the user equipment is at the ...
