Problems solved by technology

It can be seen that in this solution, the bandwidth cannot be reasonably allocated according to the bandwidth demand of the current business. For example, if there are no EF services and AF services in the authorized time slot, or when there are few EF services and AF services, the bandwidth will be allocated for it. Allocate fixed bandwidth or bandwidth that satisfies Wmin / Wmax, so that the bandwidth cannot be used reasonably; on the other hand, if the bandwidth is insufficient, low-priority BE services will be discarded, but when a user only needs low-priority services, there will be It may be that its business needs cannot be met for a long time, and the fairness of various businesses cannot be reasonably considered

Embodiment 1

[0042] see figure 1 , is a kind of bandwidth allocation method that the embodiment of the present invention provides, is used for optical line terminal OLT to allocate bandwidth for various services of optical network unit ONU end, and described method comprises the following steps:

[0043] Step S101: When the OLT receives the no-transmission service notification message reported by the EF service, it does not allocate the EF service bandwidth; The application bandwidth carried in the EF service allocates bandwidth for the EF service.

[0044] Preferably, the allocation of bandwidth for EF services according to the application bandwidth carried in the REPORT message based on the principle of using the remaining bandwidth in the link as much as possible is as follows:

[0045] When R 请EF SLAEF When , the allocated bandwidth for EF service is R 请EF ;

[0046] When B SLAEF 请EF total -B SLAAF -B slabe When , the allocated bandwidth for EF service is R 请EF ;

[0047] When...

Embodiment 2

[0060] see figure 2 , a bandwidth allocation module provided by an embodiment of the present invention, which is set at the OLT end of the optical line terminal, and is used to allocate bandwidth for various services at the ONU end of the optical network unit, including:

[0061] The EF service bandwidth allocation sub-module 201 is configured to not allocate EF service bandwidth when receiving the no-transmission service notification message reported by the EF service, and to utilize the remaining bandwidth in the link as much as possible when receiving the REPORT message reported by the EF service In principle, the bandwidth is allocated for the EF service according to the requested bandwidth carried in the REPORT message.

[0062] Preferably, the EF service bandwidth allocation sub-module 201 allocates bandwidth for the EF service according to the application bandwidth carried in the REPORT message based on the principle of utilizing the remaining bandwidth in the link as ...

Abstract

The invention discloses a bandwidth allocation method and a bandwidth allocation module, and relates to the technical field of access networks. The method comprises that: when no transmission service notification message reported by an EF service is received, an EF service bandwidth is not allocated; when REPORT message reported by the EF service is received, the bandwidth is allocated to the EF service based on the principle of using the rest bandwidth in a link as much as possible according to the applied bandwidth; when no transmission service notification message reported by an AF service is received, an AF service bandwidth is not allocated; when REPORT message reported by the AF service is received, the bandwidth is allocated to the AF service based on the principle of using the rest bandwidth in the link as much as possible according to the applied bandwidth; and a BE service assured bandwidth is allocated to a BE service. The module comprises an EF service bandwidth allocation sub-module, an AF service bandwidth allocation sub-module and a BE service bandwidth allocation sub-module. Based on the principle of using the rest bandwidth in the link as much as possible, the bandwidth can be reasonably utilized, and the fairness of various services can be taken into reasonable consideration.

Description

technical field [0001] The invention relates to the field of access network technology, in particular to a bandwidth allocation method and module. Background technique [0002] With the popularization of the Internet and the rapid development of Internet technology, the number of network users and business volume have increased rapidly. To meet the needs, the backbone network has reached Gigabit or even 10 Gigabit. At the same time, the local area network on the user side has also reached hundreds of megabits. Therefore, optical fiber access technology has gradually become the mainstream. Among them, Ethernet Passive Optical Network (EPON) combines the advantages of low price, high bandwidth, mature technology, good compatibility, and low maintenance cost of Ethernet technology and optical fiber network, and has become the best solution to the "last mile" of the access network. Program. [0003] EPON is mainly divided into three parts, namely OLT (OPtical Line Termination,...
