Abstract

Provided are a method and device for processing a service crossing the master node, which relate to the communications field, and solve a problem of a resource conflict caused by the service crossing the master node in the OBTN. The method comprises: when assigning a bandwidth for a service requested by each node within the present DBA period, a master node selects a processing strategy; the master node eliminates, according to the selected processing strategy, a resource conflict caused by the service crossing the master node, and assigns a bandwidth to the service requested by each node. The technical solution provided by the present disclosure is applicable to the OBTN, thereby implementing highly reliable OBTN resource scheduling.

Claims11

Dependent claims

A method for processing a service crossing a master node, comprising:

selecting, by the master node, a processing strategy when assigning a bandwidth for a service requested by each node within a present Dynamic Bandwidth Assignment (DBA) period, wherein the processing strategy applied to a case where a resource conflict caused by the service crossing the master node;
and
eliminating, by the master node, the resource conflict caused by the service crossing the master node according to the selected processing strategy, and assigning, by the master node, the bandwidth for the service requested by the each node;
wherein selecting, by the master node, the processing strategy when assigning the bandwidth for the service requested by the each node within the present DBA period comprises:
selecting, by the master node, the processing strategy for the service crossing the master node according to a requirement of a DBA operation, wherein the processing strategy comprises at least one of the following:
a retention strategy or an elimination strategy;
wherein the retention strategy comprises:
a state of the service crossing the master node of a previous correlative frame is transmitted to a present frame set;
and the elimination strategy comprises:
a service crossing the master node is eliminated from the previous correlative frame set;
wherein a DBA period is M times of a frame period, a ring period is N times of the frame period, M and N are integers, and M is an integral multiple of N or N is an integral multiple of M, and the selecting, by the master node, the processing strategy for the service crossing the master node according to the requirement of the DBA operation, wherein the processing strategy comprises at least one of the following:
the retention strategy or the elimination strategy, comprises:
in a case where M is slightly greater than N or M=N or M<N, selecting the retention strategy;
and
in a case where M is much greater than N, selecting the elimination strategy;
wherein when M is not greater than 8 times of N, M is slightly greater than N;
when M is greater than or equal to 8 times of N, M is much greater than N.

and the elimination strategy comprises:
a service crossing the master node is eliminated from the previous correlative frame set;
wherein a DBA period is M times of a frame period, a ring period is N times of the frame period, M and N are integers, and M is an integral multiple of N or N is an integral multiple of M, and the strategy selection component comprises:
a first selection element, configured to select the retention strategy in a case where M is slightly greater than N or M 32 N or M<N;
and
a second selection element, configured to select the elimination strategy in a case where M is much greater than N;
wherein when M is not greater than 8 times of N, M is slightly greater than N;
when M is greater than or equal to 8 times of N, M is much greater than N.
