In addition.4.1.7 Policy management • Support for two policy types: Timing execution policy and event-triggering execu tion policy. • • 6.ZXMSG 5200 Product Description 6. operation log clearance policy. EMS data are transmitted together with service data in the same data network. All rights reserved.3. the SNMP-based management inf ormation does not need the establishment of a DCN network. The user can customize the policy execution time and date so that the system will trigger the policies at the specified time. the policy is registe red and triggered in the policy engine. • In-band EMS The NetNumen N31 manages data products. Such policies are alarm clearance policy.1.1. the only standard for judging the effectiveness of the EMS channels is to check if TCP/I P links are established between the EMS (the EMS server) and the managed equipme nt. and the system supports automatic dispat ching and protection based on the network operation condition. reliable EMS chann els must be provided for the EMS.1 EMS Networking EMS Data Channels To ensure that the EMS can stably manage the equipment in it.1. A simple method is to use the ICMP P ing tool to judge so. and creates reports periodically 6. therefore. Since ther e is no need to establish a special DNC network for the EMS. Policy customization. The centralized management mo de is generally used for the networking. In the central ized management mode. • Outband EMS In many application cases. we can consider configuring a standalone router in the EMS center to transmit all the EMS data and avoid affecting the ba ckbone equipment. that is. Because the EMS adopts the centralized management mod e. the EMS is composed of the client and the server and the w hole managed network has only one server that exchanges management information w ith all the managed equipment. The client configurations may take the fo llowing two modes: Local client and remote client. Since the outband channels are separated from the data n etwork. Also. there may be multiple clients and th ey connect with the server to implement man-machine interactions with users but cannot directly connect the equipment. the EMS data of all the managed equipment are converged at the EMS. the EMS manages plenty of equi pment distributed in the managed network in a centralized manner. for example. In contrast. The outband channels are generally implemented via the existing data network. ZTE Confidential Proprietary . the DCN ne twork in the 97 Project. • 70 © 2009 ZTE Corporation. All rights reserved. • Local client: Both the client and the server are located in the same LAN and they implement the centralized m anagement of the entire network together. in the outband ma nagement mode. Therefore. the fault information will no t be able to be reported timely and the EMS thus cannot timely monitor the netwo rk and send personnel to repair the faults when faults occur to some node equipm ent to cause the link break of the data channels.4. The outband management mode improves the reliability of the EMS.ZXMSG 5200 Product Description factors will affect the transmission of EMS information and may cause the instab ility of the EMS channels. where the data volume is tremendous. In contrast. Or the EMS can also connect the serial port of the mana ged NE via MODEM through the dialup network to implement remote configuration ba sed on man-machine commands. the remote clie nt does not directly connect the managed equipment.1.2 Centralized Management The NetNumen N31 is an EMS constructed over the data communication network. It c an maintain and manage all kinds of network equipment in a centralized manner in a broad area and complex application environment. Remote client: The client is connected with the server via the WAN and can be located in the remote equipment room to manage the local equipment by dividing management domains. standalone data channels (outband) are needed for the equipment configurations to ensure the reliability of the equipment configurati ons. the inband management channels are mutually complementary to the outband management channels to ensure the reliability of the EMS. 6. users can log in to each node to observe the running status of th e node equipment and configure it to shoot the troubles once the network perform ance is found abnormal. Because th e EMS data are transmitted through the data network established by the managed e quipment in the case of using the inband channels. so that the management terminals in the lowerlevel EMS can only access the subnets within its management right scope after lo gin to the EMS server. When the system manages a network across multiple domains. the network is split into several subnets (generally th ese subnets are divided according to the areas or the equipment type) and all th e equipment in the network are connected to the upper-level EMS to exchange mana gement information with the EMS. In the EMS server. Since there is only one EMS serv er in the entire network to exchange information with all equipment in the netwo rk. administrators c an monitor the running status of the entire network (including several subnets) through the local terminals. the management rights o f different subnets are assigned by the upper-level EMS and the data are uniform ly maintained by the upper-level EMS. In the lowerlevel EMS center. it has ZTE Confidential Proprietary © 2009 ZTE Corporation. The lower-level EMS center for managing the subnets is extended from the remote client in the upper-level EMS center to the local c lient to monitor the local subnet. 71 . Figure 16 Centralized Management Mode Two issues exist when the remote client mode is used to implement hierarchical m anagement: • The server needs higher performance.ZXMSG 5200 Product Description The remote client networking can implement hierarchical management in the centra lized management mode. thus ensuring that the upperlevel EMS can monitor the entire network and correct & reliable data are obtained. management rights can be set according to the management area and content. The lower-level EMS client can both monitor the network t hrough graphical interactions and output a variety of reports. no EMS server i s configured but there are only management terminals to exchange management info rmation with all the equipment in the local subnet via the EMS sever in the uppe r-level EMS center. When the remote c lient mode is used to implement hierarchical management. so this is equiva lent to the Manager-Agent mode in terms of management content. as shown in Figure 16.
