摘要

A communication system includes an Ethernet™ network and a MPLS-TP network connected with each other. A communication device transmits an OAM frame including frame type information showing that a frame type is an OAM frame, MPLS communication device identification information for identifying a communication device configuring the MPLS-TP network, and process content information showing a process content. When the type of a frame from the Ethernet network is an OAM frame, an edge device provides the frame with header information including an OAM identifier including MPLS communication device identification information included by the frame. When a communication device identified based on MPLS communication device identification information included by an OAM identifier of header information of a received frame is the device itself, a communication device executes an OAM process based on a process content shown by process content information.

1. A communication system in which an Ethernet™ network and a MPLS-TP (Multi Protocol Label Switching Transport Profile) network are connected with each other, wherein:
a communication device configuring the Ethernet network comprises an OAM frame transmitting unit for transmitting an OAM frame that includes frame type information showing that a frame type comprises an OAM (Operations, Administration and Maintenance) frame, MPLS communication device identification information for identifying a communication device configuring the MPLS-TP network, and process content information showing a content of a process; an edge device, which is a communication device connected with the Ethernet network among communication devices configuring the MPLS-TP network, comprises an encapsulation process executing unit for, when the edge device receives a frame from the Ethernet network, executing an encapsulation process of providing the frame with header information for transferring the frame through the MPLS-TP network; the encapsulation process executing unit is configured to, in a case where frame type information included by the received frame shows that a frame type comprises an OAM frame, provide the frame with header information including an OAM identifier including MPLS communication device identification information included by the frame; and the communication device configuring the MPLS-TP network comprises an OAM process executing unit for, when the communication device receives a frame and in a case where header information of the frame includes an OAM identifier and a communication device identified based on MPLS communication device identification information included by the OAM identifier comprises the device itself, executing an OAM process based on a content of a process shown by process content information included by the frame.
