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.

Abstract: A method for computing a frequency slot channel, a path computation element and a node are disclosed. The method includes: when a frequency slot channel needs to be established, an ingress node sending to a path computation element a path computation request message which carries spectrum resource information needed for establishing the frequency slot channel; according to the received spectrum resource information sent by the ingress node, the path computation element computing out the frequency slot channel by combining of topology information of a network and spectrum resource information of each node in the network. The path computation element includes a receiving module and a computing module. When working as an ingress node in a process of establishing a frequency slot channel, the node includes a message construction module and a sending module.

Abstract: Provided are a method and device for monitoring Operation Administration and Maintenance (OAM) performance. The method includes that: a switch receives OAM performance monitoring rules sent by a controller; the switch receives OAM performance monitoring messages, and filters the OAM performance monitoring messages according to the OAM performance monitoring rules; the switch reports each first OAM performance monitoring message obtained by filtering to the controller for processing, wherein the first OAM performance monitoring message is a message, conforming to the OAM performance monitoring rules, in the OAM performance monitoring messages. The technical solution can reduce controller performance consumption and excessive occupation of control channel bandwidth caused by reporting performance monitoring delay measurement results and packet loss measurement results.
