The invention provides an integrated management method for services and users based on an Ethernet layer-two extension technology and a system thereof, which are applied to scenes such as operation management, user access authentication, service use and the like in metropolitan area and wide area or regional Ethernet services. In the integrated management method and the system thereof, relevant fields in a message format of the Ethernet layer-two extension technology are mapped to the services and the users by utilizing characteristics of the Ethernet layer-two extension technology; definitions of various binary bits in a single field are rearranged or multiple fields are combined for use or residual numerical value space which is not fully used is used to match one or more fields which are defined in a message of the Ethernet layer-two extension technology and are not fully used currently or used as a single field with a service identification and a user identification; and integrated management problems of the services and the users are solved by operations such as service request, service status update and service quitting and the like. The integrated management method and the system thereof have advantages of high service identification efficiency, difficult forgery, strong traffic isolation and the like.
