15、e Message Delivery Protocoliv ISO/IEC 2014 All rights reserved ISO/IEC 17811-1:2014(E) Introduction This International Standard provides the architecture for device control and management (DCM). DCM can support the various control and management services, regardless of the network protocols or inter

16、faces. DCM is composed of two protocols: DCMP (Device Control and Management Protocol) and RMDP (Reliable Message Delivery Protocol). This International Standard consists of the following parts: Part 1: Architecture Part 2: Specification of Device Control and Management Protocol (DCMP) Part 3: Speci

17、fication of Reliable Message Delivery Protocol (RMDP) Part 1 of ISO/IEC 17811 describes the architecture of DCM, which includes definition, general concept, requirements, design principles, service scenarios for device management control, and management. Part 2 of ISO/IEC 17811 specifies the Device

18、Control and Management Protocol (DCMP), which includes the functional entities, protocol operations, message structure, and detailed parameter format associated with DCMP.

For this purpose, DCM is composed of two protocols

28、es various functions for the device management. DCM supports the device and network status information retrieval, device and network initialization, firmware and software update, file transmission and so on. In an administrative domain, there may be a device management server that collects, controls

29、, and manages devices using DCMP. To exchange DCMP messages among the devices, RMDP is needed. RMDP is a message exchange protocol among the devices regardless of the network protocols or interfaces. The detailed protocol stack of DCM is illustrated in the Figure 1. Figure 1 Protocol Stack for the D

30、CM Basically, DCMP messages can be exchanged using the RMDP. RMDP has node information, which maintains the mapping information between DCM device identifier and physical network identifier, such as the IP address and port number in IP network. If there is a device management server (DMS) in an admi

31、nistrative domain, the RMDP might be able to obtain the node information about all devices that 2 ISO/IEC 2014 All rights reserved ISO/IEC 17811-1:2014(E) are connected in the administrative domain from the DMS. Note : There are several ways to retrieve node information. For example, the RMDP is abl

32、e to request node information by using the RMDP messages when there is no DMS or when DMS does not response. Therefore the node retrieval mechanisms depend on implementation. When the RMDP retrieves the node information without DMS, the integrity of node information may not be guaranteed After RMDP

33、retrieves the target node information, DCMP messages, such as DEVICE_INFORMATION_ REQUEST or DEVICE_CONTROL_REQUEST, can be transferred to the target device using RMDP. 6 DCM Service Environments 6.1 Case 1: Local Network with Device Management Server Figure 2 shows an example of DCM service environ

34、ment where all devices and a management server are connected in a local network with device management server (DMS). The DMS retrieves device information in the administrative domain and manages devices with DCMP. In this environment the information device, such as smart phone, is able to control th

35、e devices using the DCMP. When smart phone join the administrative domain, RMDP on smart phone could find the DMS and receive the node information about whole devices which are connected in that administrative domain from the DMS. Then DCMP on the smart phone sends the device discovery request messa

36、ge to the other devices and receives the response message by using the RMDP. After that, smart phone is able to see the all devices in the network. If the target device is selected and control information is available by user, DCMP generates and transmits the device control request messages to the t

37、arget device by using the RMDP. Figure 2 DCM service environment case 1: Local network with device management server 6.2 Case 2: Local Network without Device Management Server Figure 3 shows the example of DCM service environment where all devices are connected in the local network without device ma

38、nagement server. The information device, such as smart phone, can control the DCM devices by using the DCM based application. When a node discovery request message is broadcasted by RMDP on the smart phone, RMDPs on the other devices which receive the node discovery request message would response wi

39、th their node information. Then DCMP on the smart phone sends the device discovery request message to the other devices and receives the response message by using the RMDP. After that, smart phone is able to see the all devices in the network. If the target device is selected and control information

40、 is entered by user, DCMP generates the device control request message and sends that control message to the target device by using the RMDP. ISO/IEC 2014 All rights reserved 3 ISO/IEC 17811-1:2014(E) Figure 3 DCM service environment case 2: Local network without device management server 6.3 Case 3:

41、 Public Network with Device Management Server Recently, more devices are connected to the internet directly and provide various services to users as shown in Figure 4. For example, one of the health care product manufacturers sells the scales that are connected to the internet and upload the users w

42、eight and fat data to the manufacturer server automatically. Then, users can check the changes of their own body weight and fat easily by using the smart phone application. For this service, each scale sends the node advertisement message to the device management server using the RMDP that is instal

43、led when the device is manufactured. Then, also DCMP on scale sends the device advertisement message, device registration message and user registration message to the device management server using the RMDP. After these processes, DCMP on scale is able to upload their own data to device management s

44、erver using RMDP. Figure 4 DCM service environment case 3: Public network with device management server 7 Requirements 7.1 S elf-C onfigur ation When a device is connected to a network, the device is automatically plugged in and is used by many different users. The auto configuration can be achieved

45、 in two levels. First is the network auto configuration. When a device is connected to the network, the network configuration shall be set up 4 ISO/IEC 2014 All rights reserved ISO/IEC 17811-1:2014(E) automatically. For example, when a device is connected to the IP network, IP address could be assig

46、ned by the DHCP (Dynamic Host Configuration Protocol) or Auto IP. In addition, all service available in a network are detected and advertised automatically. Each device has different capabilities and thus available services are different. Therefore users know a set of available services for each dev

47、ice. Then user detects available services and start services among them. The service detection and running is performed automatically without any intervention. 7.2 Multiple Administrative networks Devices are connected to the different networks where it is located. So, the network protocols for the

48、networks shall not be network dependant. This means that network independent device management mechanism is required regardless of where a device is located. Since a device is access through multiple administrative network depending on the network hierarchy. Different administrative policy may be en

49、forced to each device where it is located. So, the device management scheme is required to deal with the multiple administrative policies. 7.3 Uniform device interface A user wants to control many different types of device regardless of the manufacturer, device type and device location. However, different types of device provide different device functions while same type of devices is provide some common functions. So, device control and management architecture covers various types of devices. Since the dev
