Embodiment Construction
[0051] The core idea of the present invention is to utilize the set multi-channel input rate shaper (i.e. Shaper) to realize the effective utilization of bandwidth resources in the RPR network, so that the rate shaper allocated recyclable bandwidth resources does not use the bandwidth resources in its own business. In some cases, the reclaimable bandwidth resource can be used by other services.
[0052] The specific implementation of the method of the present invention is as follows:
[0053] First of all, it is necessary to set corresponding rate shapers for different types of services in the RPR network, and set the control parameters and transmission control modes of each rate shaper respectively. The transmission control mode includes the associated way to control;
[0054] The different types of business are: in the RPR network, according to the transmission priority of the business to be transmitted, it is divided into different types of business, and the different ty...

A method for effectively utilizing bandwidth resource in resilient packet ring network includes utilizing input speed rate reshaper with multi-channel to control and manage bandwidth resource in RPR network to let each said shaper occupy recoverable bandwidth resource for setting said shaper so as to effectively ensure resource utilization in RPR network , simultaneously designing relevant ensuring measures to ensure that recoverable bandwidth distributed to said shaper but occupied by the other service can be recovered when recoverable bandwidth is required by said shaper .
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a bandwidth allocation method and device for different types of services in an elastic packet ring network. Background technique [0002] RPR (Resilient Packet Ring) technology is a new MAN networking technology, which belongs to the MAC (Media Access Control) layer protocol. RPR technology is proposed to optimize the transmission of data packets. The economy of network technology, SDH (Synchronous Digital Hierarchy) technology strictly guarantees delay and jitter, and features such as 50ms ring network ring protection and recovery, and has the characteristics of space multiplexing, bandwidth dynamic allocation, and support for multiple service levels. This makes it an optimization technology for transmitting data packets on the current optical network, and is receiving extensive attention and attention from the industry. [0003] In order to have a further underst...
