Method for adjusting link capacity

Abstract

The invention discloses a link capacity regulating method, for regulating bandwidth configuration of a communication system, including the steps: an initiating end sends a configuration change request message; a response end receives this message and then regulates member channel and constructs a protocol message containing its own state number and the member channel needing to be regulated, and sends the protocol message through service message transmission path to the response end; the response end receives the protocol message and then regulates the member channel and also constructs a protocol message containing its own state number, and then sends back this protocol message through the service message transmission path to the initiating end. The invention can be applied to many kinds of communication systems, convenient to extend and able to fully multiplex transmission bandwidth.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for reasonably adjusting the bandwidth configuration of a communication system. Background technique [0002] Generally speaking, a communication system is composed of a source end and a sink end; where information is sent by the source end and received by the sink end. [0003] see figure 1 , the usual communication systems are bidirectional, that is, the initiator 10 and the responder 20 of the communication respectively have a source device 11, 21 for sending information to the other party, and a sink device for receiving information sent from the other party End devices 12, 22; therefore, the entire communication system can be regarded as two opposite directions and highly independent information source-sink combination. Of course, the positions of the initiator and the responder of the communication system can also be changed. [0004] Usually, the bandwidth configured ...

Problems solved by technology

[0012] First, the existing LCAS technology is a link capacity adjustment method based on virtual concatenation, and its application is bound to be limited

Because many of the current technologies for bundling several channels to obtain channels with larger bandwidth (such as ML-PPP protocol) are not based on virtual concatenation, so the existing LCAS technology cannot be used;

[0013] Second, the existing LCAS technology interaction control information is realized through the H4 and K4 overhead bytes in the SDH frame structure, that is to say, this technology can only be applied to SDH-based transmission systems, other systems (such as data communication Twisted pair port TRUNK in the field) because the SDH technology is not used, the existing LCAS technology cannot be applied;

[0014] Third, the communication system needs to continuously and automatically detect the availability of each member channel during communication. Since the existing LCAS technology is implemented based on the SDH transmission network, and the existing SDH technology provides a convenient and complete hardware detection mechanism, the existing The current LCAS technology does not take this into consideration, and it is all implemented through hardware. Although the functions can be reliably realized through hardware, it also has the disadvantage of being inconvenient to expand.

[0015] Fourth, the existing LCAS technology is inconvenient to implement flexible bandwidth allocation strategies, unless the interface with LCAS technology is specially developed to expand the existing LCAS technology, even so, hardware interface support is still required
