Description

网络设备管理方法、网络设备和网络设备管理系统技术领域 Network device management method, a network device and the network device management system Field

本发明涉及通信网络管理,尤其涉及一种网络设备管理方法、 网络设备和网络设备管理系统。 The present invention relates to communications network management, and particularly to a network device management method, a network device and a network device management system.

背景技术 Background technique

随着网络规模不断扩大,业务及应用的复杂性不断增加,用户对网络的性能要求越来越高,如果没有一个高效的网络管理系统对网络系统进行管理,那么,很难保证网络的正常运行。 As networks have been expanding, the complexity of services and applications continues to increase, users on the network performance requirements are high, if not an efficient NMS network management system, it is difficult to ensure the normal operation of the network . 一般来说, Generally speaking,

网络管理内容包括:通过某种方式对网络进行管理,协调和组织网络资源,使其得到更加有效的利用;维护网络的正常运行,在网络出现故障时能及时报告并进行有效处理。 Network management includes: be some way to network management, coordination and organization of network resources to be more effectively utilized; maintain the normal operation of the network, timely reporting and effective treatment when the network fails.

电信管理网络(TMN)层次模型(如图1所示)是用于表示通信网络管理方法的参考模型。 Telecommunications Management Network (the TMN) hierarchical model (Figure 1) is a reference model for representing a communication network management method. 国际电信联盟-电信标准部(ITU-T) 于1988年在建议M.3010和其它文档中对电信管理网络体系进行了定义。 International Telecommunication Union - Telecommunication Standardization Sector (ITU-T) in 1988 recommended M.3010 and other documents for telecommunications network management system is defined.

该体系结构的最大好处是将通信网络管理划分为五个功能层次:业务管理层(BML)、服务管理层(SML)、网络管理层(NML)、 网络设备管理层(EML)以及管理层中的网元(网络单元NE,亦称网络设备)。 The greatest benefit of this architecture is divided into five functional communications network management levels: Business Management (BML), service management (SML), network management layer (NML), network device management (EML) as well as the management of NE (network elements NE, also known as network devices). 电信管理网络(TMN)基于这些层次对管理责任进行了分割,使服务运营商的管理功能或应用得以分散,并且使这些功能和应用可以使用不同的操作系统、不同的数据库以及不同的编程语言。 Telecommunications Management Network (TMN) based on these levels of management responsibilities were divided, the management function or application service operators to disperse, and these features and applications can use different operating systems, different databases and different programming languages.

完成网络管理所定义内容的软件和硬件系统称为网络管理系统(NMS),而仅对单个或部分网络设备进行管理的系统通常称为网络设备管理系统(亦称网元管理系统EMS,或管理台),网络设备管理系统处于电信管理网络层次模型中的网元管理层,用于管理一个或多个类型的通信网络设备。 Complete the network-defined contents management software and hardware systems called a Network Management System (NMS), while only a single device or a part of the network management system managing the network device management system is generally referred to as (element management system known as EMS, or Taiwan), network device management system in a telecommunication management network element management level model for managing one or more types of communications network equipment. 网络设备管理系统是伴随通信网络的发展而产生的。 Network equipment management system is accompanied by the development of communication networks generated. 旧的通信网络在设计的时候仅仅考虑了语音交换业务,并且旧的网络是用于用户访问和电话交换网络以处理呼叫的铜线回路,因此其结构相对地比较简单。 The old communication network is only considered when designing a voice switching service and the old network for user access and circuit switched telephone network in copper processing a call, and therefore its structure is relatively simple. 当前,通信网络已经发展为集普通数据传输、语音交换、高速数据以及视频传输等功能为一体的网络。 Currently, communication networks have been developed for the normal data transmission, the exchange of voice, video and high speed data transmission and other functions as one of the network. 由于实现这些功能的技术具有高度复杂性,因此伴随着每种网络设备技术的出现,都会出现与之对应的利用该技术优势的网络设备管理系统。 Since these functions to achieve a high degree of technical complexity, so with the advent of each network device technologies, there will be use of the technological advantages of network device management system corresponding thereto.

通常,将网络设备管理系统应用于一组相同类型的网络设备或者网络设备系统,网络设备管理系统将详细的信息汇总为信息模型, Typically, the network device management system is applied to a group of the same type of network device or a network device system, network device management system will be detailed summary of the information model,

通过接口提供给更高层的网络管理系统(NMS)。 To provide higher-level network management system (NMS) through the interface.

网络设备管理系统在整个通信管理解决方案中是关键部件。 Network device management system is a key component in the entire communication management solutions. 网络设备管理系统是网络设备信息的传递者和网络管理系统中的网络设备控制者。 Network device management system is a network device and network controller transmitting the device information management system in the network. 通常,将网络设备管理系统与特定的网络设备类型进行匹配,并且网络设备管理系统必须与通信网络中的网络设备一起应用以便启动和管理网络设备的功能。 Typically, the matching network device management system with a particular type of network equipment, network equipment and management systems must application function to initiate and manage network devices with network devices in a communication network.

图2A示出一种根据现有技术的通信网络管理系统。 FIG 2A illustrates a communication network management system according to the prior art. 该通信网络管理系统包括许多不同的厂商提供的多种网络设备(NE)、管理这些网络设备的网络设备管理系统(EMS)以及管理所述网络设备管理系统的网络管理系统(NMS)。 The communications network management system includes a plurality of multiple network devices (NE) provided by different vendors, the network management devices network device management system (EMS) and the network management device management system a network management system (NMS). 网络设备和其网络设备管理系统之间的通信协议根据网络设备的不同而不同,也就是说根据网络设备的制造厂商的不同而不同。 Communication protocol between the network device and the network device management system according to which the different devices and different networks, i.e. depending on the manufacturer of the network device to another. 例如,网络设备管理系统和网络设备之间的协议可以是TL,、信令网络管理协议(SNMP)以及通用管理信息协议服务单元(CMISE)等。 For example, the agreement between the network device management system and the network device may be a TL ,, Signaling Network Management Protocol (SNMP) and Common Management Information Protocol service unit (CMISE-) and the like. 如图2A所示,通信网络中的每个网络设备在某一时刻仅仅与一个网络设备管理系统通信。 2A, the communication network to communicate with each network device is merely a network device management system at a time. 例如,网络设备管理系统EMS1与网络设备NE1进行通信;网络设备管理系统EMS2与网络设备NE2进行通信,等等。 For example, network device management system EMS1 NE1 with the network device communications; EMS2 network device management system in communication with the network device NE2, and the like. 对于某个网络设备特定的网络设备管理系统通过专用的或者开放的、标准的界面与提供集成化多厂商网络管理的高层网络管理系统通信。 , Communications interface for a network device-specific network device management system via a dedicated or open standards and providing integrated multi-vendor network management of high-level NMS.

如上文所述,在传统的电信网络中,在同一时刻, 一个网络设 As described above, in the conventional telecommunication networks, at the same time, a network device

备只能由一个网络设备管理系统进行操作维护。 Preparation can only be operated is maintained by a network device management system. 由该网络设备管理 By the network device management

系统通过专用的数字通信网(DCN)对该网络设备进行配置数据下发、告警以及性能数据的采集。 The system configuration data issued, the alarm and performance data collected by the network device dedicated digital communication network (DCN).

在这种传统网络管理系统管理下,远端的操作中心难以获得现场的即时信息。 In this traditional NMS management, remote operations center site is difficult to obtain real-time information. 尤其是网络设备开始启动的时候,由于网络设备管理系统需要对其进行较多的配置操作并且通信网络的拓朴连接结构也还不够稳定,远端的操作维护人员不能通过网络设备管理系统迅速了解网络设备启动的情况。 In particular network equipment started, because of the network device management system needs to be more connected topology structure configuration and operation of the communications network is also not stable enough, remote operation and maintenance personnel can not quickly understand network equipment management system the network equipment started.

另外, 一个网络设备在同一时刻只能由一台网络设备管理系统进行管理,降低了设备管理的灵活性。 In addition, a network device can only be managed by a single network device management system at the same time, it reduces the flexibility of device management. 而且网络设备仅由一台网络设备管理系统管理,无法实现多级行政区域对网络设备的分级监控。 And network equipment only consists of a network device management system management, not multi-level administrative region of hierarchical network monitoring devices. 例如,网络设备启动时的调试测试和监测网络设备运行所关心的信息是不同的,因此需要分级监控机制提高系统的灵活性。 For example, testing, and debugging information to monitor network devices running the network device startup of interest are different and therefore require classification monitoring mechanisms increase the flexibility of the system.

当网络设备801接受网络设备管理系统802发起的连接请求以后,向网络设备管理系统802分配一个新的Invoke—ID,并产生一个新的servant服务于该网络设备管理系统802。 When the network device 801 accepts the connection request initiated by the network device management system 802 to assign a new network device to Invoke-ID management system 802, and generates a new servant serving the network device management system 802. 当网络设备管理系统802 得到新的InvokeJD时,网络设备管理系统802在一个连4妄会话内始终储存该值,每一次向网络设备801发起操作的时候,都携带该值用于向网络设备801标识身份。 When the network device management system 802 to obtain a new InvokeJD, the network device management system 802 in a session even 4 jump always store the value, every time the network to initiate the operation of device 801, carries the value of a device to the network 801 logo identity.

下面参照图9描述根据本发明的一个实施例的网络设备的工作模式,以及上述几个工作模式之间的转换方法。 9 depicts a method for converting the operating mode between a network device in accordance with one embodiment of the present invention, the above and below with reference to several working modes.

图9示出了网络设备的工作模式转换的过程。 FIG 9 shows a network device or operating mode conversion. 在本地/远端网络设备管理系统902、卯3的请求下,网络设备可在这三种模式之间转换。 At the request of the local / remote network device management system 902, d 3, the network device can be switched between modes. 当网络设备卯l处于只读模式或者共享模式下的时候,如果多个网络设备管理系统同时接入网络设备901 ,则网络设备管理系统902或903都可以指示网络设备901转入专用模式,但是优选地只由本地设备管理系统卯2指示网络设备901转入专用模式。 When the read-only mode or shared-mode network device is d l, if a plurality of network device management system access the network device 901, the network device management system 902 or 903 may indicate that the network device 901 into the dedicated mode, but preferably only into the dedicated mode by the local management system of the device 2 indicates that the network device 901 d. 如果只有一台网络设备管理系统连接到网络设备901 ,则无论与所述网络设备901连接的网络设备管理系统是远端网络设备管理系统903还是本地网络设备管理系统902,网络设备901都可以转入专用模式。 If only one network device management system connected to the network device 901, regardless of the network device management system connected to the network device 901 is a remote network device management system 903 or local network device management system 902, network device 901 may be transferred the dedicated mode.

当本地网络设备管理系统902指示网络设备901转入专用模式时,网络设备901立即中断与其他网络设备管理系统903的会话连接。 When the local network device management system 902 to instruct the network device 901 into the dedicated mode, the network device 901 to other disconnect the session immediately network device management system 903. 网络设备901立即清空远端网络设备管理系统903的Invoke—ID和IOR,并释放所记录的远端网络设备管理系统903的IP地址。 Network device 901 immediately empty remote network device management system and the IOR Invoke-ID 903, and releases the remote network device management system 903 records the IP address.

在到所有远端网络设备管理系统903的连接被释放之前,网络设备901并不通知远端网络设备管理系统903,而当远端网络设备管理系统903向网络设备901发送的存活检测(Health check )信号(即, 用于检测连接状态的请求)超时以后,该远端网络设备管理系统自动认为已经与该网络设备失去联系,并释放相关的资源上下文。 Before being released to connect all the remote network device management system 903, the network device 901 does not notify the remote network management system apparatus 903, and when the detected survival (Health check a remote network management system apparatus 903 transmits to the network device 901 ) signal (i.e., a request for detecting the connected state) after a timeout, the remote network device management system automatically considered to have lost contact with the network device, the context and releases related resources.

当网络设备90l处于专用模式下时,网络设备901只能接受一个网络设备管理系统的控制并且能够接受控制该网络设备901的网络设备管理系统发起的任何操作。 When a network device 90l is in dedicated mode, the network control device 901 can accept a network device management system and can accept any operation of the control device 901 of the network management system initiated by the network device. 接受一个网络设备管理系统的控制之后,处于专用模式下的网络设备901拒绝任何其他网络设备管理系统的连接^青求。 After acceptance control a network device management system, the network device 901 is in dedicated mode rejects the connection any other network device management system requirements ^ green.

当网络设备901处于专用模式下并且与本地网络设备管理系统902的连接中断以后,即此时没有一台网络设备管理系统与网络设备901连接,网络设备901自动转入只读才莫式,可以允许其他新的网络设备管理系统进行接入。 When the dedicated mode and the network device 901 is later connected to the local network device management system 902 is interrupted, i.e. this time no one network device management system connected to a network device 901, network device 901 is automatically transferred to the read-only Mohs only be other devices allow new network management system access.

当网络设备901处于专用模式下时,在接受本地网络设备管理系统902的请求之后,可以转入只读模式或者共享模式。 When the network device 901 is in dedicated mode, after receiving the request the local network device management system 902 may be transferred to a read-only mode or shared mode. 当网络设备901 进入只读模式或者共享模式以后,网络设备901可以接受任何远端网络设备管理系统903的连接请求。 When the network device 901 enters a read-only mode or a sharing mode, the network device 901 can accept any connection request to a remote network device management system 903.

当网络设备901处于只读模式下时,它将拒绝任何"写"操作,但是能够进行性能数据的查询、告警管理以及配置数据的查询。 When the network device 901 is a read-only mode, it will reject any "write" operation, but can be query, alarm management, and performance data of the configuration data.

下面参照图IO描述本发明的网络设备在共享模式下保持数据修改的一致性的方法。 Described method for data consistency modifying network device according to the invention held in a shared mode described below with reference to FIG IO.

图IO示出根据本发明的网络设备在共享模式下保证数据修改的一致性的示意图。 IO shows a schematic view of FIG consistent data modified in accordance with the present invention is to ensure the network device in shared mode. 当网络设备处于共享模式下时,任何一个网络设备管理系统1002或1003都能够向网络设备1001发起配置数据的修改请求。 When a network device is in the shared mode, any of the network device management system 1002 or 1003 can initiate a request to modify the configuration data to the network device 1001. 如果没有数据修改一致性的保证,就有可能造成网络设备中的配置数据与网络设备管理系统中的配置数据不一致。 If no data is modified to ensure consistency, it may cause network device configuration data and configuration data network device management system is inconsistent. 如图IO所示,如果网络设备管理系统1002所发起的数据修改请求是通过Corba接口下发的,则网络设备1001接受该请求,并在完成数据修改以后,通过事件报告通知所连接的其他网络设备管理系统1003。 FIG IO, the data modification request if the network device management system initiated by the Corba Interface 1002 is issued, the network device 1001 accepts the request, and after completion of the data changes, the event report notification via other networks equipment management system 1003. 这样,就能够保证其他网络设备管理系统的数据的一致性。 In this way, we can ensure the consistency of data with other network devices management systems.

当某台网络设备管理系统1002进行批量数据更新的时候,会更新网络设备1001的整个MIB库(管理信息库)。 Time when a network device management system 1002 batch data update will update the entire network equipment 1001 the MIB (Management Information Base). 如果所述网络设备IOOI 同样将配置更新的结果以事件报告的方式通知其他网络设备管理系统1003,则无疑将大大增加网络设备的负担,并且该方式效率低下。 If the network device IOOI the same configuration update notification event reports in a manner other network device management system 1003, it will undoubtedly greatly increase the burden of network devices, and low efficiency of the way. 所以,在网络设备管理系统1002发起批量数据更新时,网络设备IOOI 拒绝其他任何网络设备管理系统1003所发起的任何操作(存活检测除外),包括拒绝本网络设备管理系统的模式转换操作。 Therefore, the network device management system 1002 initiates batch data updating, the network device IOOI reject any operating any other network device management system 1003 originated (except survival detection), including the rejection mode network device management system of the present switching operation. 当批量数据更新成功结束以后,网络设备1001向其他所有的网络设备管理系统1003发送数据同步请求,要求其他网络设备管理系统1003与网络设备1001进行配置数据的同步操作。 When the end of the batch data update is successful, the network device 1001 to send data synchronization request 1003 to all other network device management system, the requirements of other network device management system 1003 synchronize the configuration data to the network device 1001.

为了保证多网络设备管理系统的配置数据的高可靠性,在多网 In order to ensure high reliability of the multi-network device configuration data management system, the multi-network

络设备管理系统的环境中,多个网络设备管理系统1002和1003有可能同时向同一网络设备1001发起相同的操作。 Environmental network device management system, a plurality of network device management system 1002 and 1003 may also have the same operation initiating device 1001 to the same network. 在网络设备1001处于共享模式或者只读模式下时,当网络设备1001接收到第一个请求并开始处理该请求但还未作出回应的时候,如果接收到来自另外一个网络设备管理系统的相同请求,则网络设备1001的处理策略为一律 When network device 1001 is in the shared mode or read-only mode, when the network device 1001 receives the first request and begins processing the request, but not yet time to respond, if receiving the same request from another network device management system , the processing strategy for all network equipment 1001

拒绝该请求。 Deny the request.

当任何网络设备管理系统1002或1003发起模式转换请求的时候,网络设备1001必须确保并没有正在进行的"写,,操作。如果当前正在处理的数据修改请求还没有得到回应,则必须等待该网络设备IOOI作出回应以后再进行模式转换操作。 When any network device management system 1002 or 1003 launch mode conversion request, the network device must ensure that 1001 is not going ",, write operation. If the data modification request is currently being processed has not been a response, you must wait for the network IOOI device then converts the operating mode to respond later.

下面参照图3描述根据本发明的一个优选实施例,即,网络设备响应于网络设备管理系统的请求而在所述三种工作模式之间所进行的切换操作以及在每个工作模式下的处理过程。 FIG. 3 is described below with reference to a preferred embodiment of the present invention, i.e., the switching operation of the network device in response to a request network device management system being performed between the three modes of operation and a processing in each mode of operation process.

图3示出根据本发明优选实施例的网络设备工作模式切换方法的流程图。 Figure 3 shows a flowchart of a network device operating mode switching method according to a preferred embodiment of the present invention embodiment.

图3的流程开始于步骤301。 Process 3 begins at step 301. 在步骤302,网络设备判断是否接收到来自网络设备管理系统的连接请求。 In step 302, the network device determines whether it has received a connection request from a network device management system. 如果接收到连接请求,则处理转到步骤303,否则就定期执行该判断,直到接收到一个连接请求时为止。 If the connection request is received, the process proceeds to step 303, otherwise perform the determination periodically, until such time as a connection request is received.

在步骤303至步骤310,网络设备根据自身工作模式允许或拒绝网络设备管理系统的连接请求,允许或禁止对该网络设备进行管理操作。 In step 303 to step 310, the network device to allow or deny the connection request network device management system according to the working mode, permit or prohibit the operation of the network management device.

在步骤303,网络设备判断自身是否处于专用模式下。 In step 303, the network device determines whether it is in dedicated mode. 如果网络设备处于专用模式下,则处理转到步骤304,否则网络设备就处于共享模式或只读模式下,并且处理转到步骤306。 If the network device is in a dedicated mode, the process proceeds to step 304, otherwise the network device is in shared mode or the read-only mode, and the process proceeds to step 306.

在步骤304,网络设备处于专用模式下,只允许与一个网络设备管理系统建立连接,因此网络设备需要判断是否有已经连接到其本身的网络设备管理系统。 In step 304, the network device is in a dedicated mode, only establish a connection with a network device management system, the network device needs to determine whether there has been connected to its own network device management system. 如果已经有网络设备管理系统与该网络设备建立了连接,则处理转到步骤307,该网络设备拒绝其它网络设备管理系统发送的连接请求,并且处理转到步骤311,否则处理就转到步骤305。 If you already have network device management system with the network connection device is established, the process goes to step 307, the network device rejects the connection request sent to other network device management system, and the process goes to step 311, otherwise the process goes to step 305 .

在步骤305,网络设备与网络设备管理系统建立连接,以下将结合图4对该连接过程进行详细描述。 In step 305, the network device to establish a connection with the network device management system, in conjunction with the connection process will be described in detail in FIG. 4 this. 接着转到步骤309,允许网络设备管理系统进行管理操作。 Then passes to step 309, network device management system allows for management operations. 然后执行步骤311,判断是否满足断开连接的条件,下文中将详细描述该步骤。 Then step 311 determines whether or disconnected condition is satisfied, this step will be described in detail below.

在上文所述的步骤303中,如果网络设备判断其自身不处于专用模式下,则转到步骤306,建立连接。 In the above step 303, it determines if the network device itself is not in a dedicated mode, then proceeds to step 306, to establish a connection. 然后执行步骤308,网络设备判断自身是否处于共享模式下,如果网络设备处于共享模式下, 则处理转到步骤309,否则处理就转到步骤310。 Then step 308 is executed, the network device determines whether it is in shared mode, if the network device is in the shared mode, the processing proceeds to step 309, otherwise the process goes to step 310.

在步骤309,如果网络设备处于专用模式下,则允许网络设备管理系统对该网络设备进行任何操作;如果网络设备处于共享模式下, 则由于所述网络设备同时受到多个网络设备管理系统的控制,因此网络设备管理系统对网络设备所进行的操作会存在某些限制,以下将对这些限制进行描述。 In step 309, if the network device is in a dedicated mode, the network device management system allows operation on any network device; if the network device is in the shared mode, since the plurality of network devices controlled by the network device management system , the operator of the network device management system will be performed by network devices there are some restrictions, restrictions will be described hereinafter. 如果某个网络设备管理系统通过Corba接口发送数据修改请求,则网络设备接收、完成该请求后,通过Corba 接口的事件报告通知其它与之连接的网络设备管理系统。 If a network device management system Corba interface to send data via the modification request, the network device receives, after the completion of the request, notifies the other network device management system connected thereto via event report Corba interface. 如果所述请求要求进行的是批量数据更新(例如,对网络设备的整个管理信息库(MIB)的更新),则使用事件报告无疑会加重网络设备的负担。 If the request requires that bulk data update (for example, to update the entire network equipment management information base (MIB)), then use the event report will undoubtedly increase the burden of network devices. 因此,当本发明的网络设备管理系统发起批量数据更新时,网络设备将拒绝其它任何网络设备管理系统对其进行的除了存活检测(Health Check)之外的任何操作。 Thus, when the network device management system according to the present invention is initiated when the batch data update, the network device will reject any operation other survival detector (Health Check) than any other network device management system of them. 并且在数据更新完成之后,网络设备将向其它所有网络设备管理系统发送数据同步请求,要求其它网络设备管理系统进行配置数据同步操作,以保持数据的一致性。 And after the data update is complete, the network device will send a data synchronization request to all other network device management system, device management system requirements other network configuration data synchronization operations to maintain data consistency.

如上文所述,在步骤308中,如果网络设备判断其自身不处于共享模式下,则该网络设备处于只读模式下,并且处理转到步骤310。 As described above, in step 308, it determines if the network device itself is not in shared mode, the network device is in read-only mode, and the process proceeds to step 310. 在步骤310,由于网络设备处于只读模式下,因此不允许网络设备管理系统对该网络设备的配置数据进行修改,但允许网络设备管理系统进行其它的管理操作。 In step 310, since the network device is in a read-only mode, the network device management system is not allowed to modify the configuration data to the network device, but allowing the other network device management system for management operations.

在上述步骤307、 309和310之后,处理都转到步骤311。 After the above step 307, 309 and 310, all the processing proceeds to step 311. 在步骤3U,网络设备判断是否满足断开连接的条件。 In step 3U, the network device determines whether the condition is satisfied disconnected. 该条件可以是网络设备管理系统向该网络设备发送断开请求,还可以是网络设备收到与其连接的多个网络设备管理系统之一发出的专用模式转换请求。 The condition may be a network device management system by sending a disconnect request network device, the network device may also receive one of the plurality of dedicated mode, the network device management system connected thereto conversion request issued.

在步骤312,该网络设备与该网络设备管理系统的连接将被断开。 In step 312, the network device connected to the network device management system will be disconnected. 在步骤313,处理结束。 In step 313, the process ends.

图4示出根据本发明优选实施例的网络设备管理系统与网络设备建立连接过程的流程图,即图3中的步骤305、 306。 Figure 4 shows a flowchart of the process of establishing a connection according to the network device management system according to a preferred embodiment of the present invention, a network device, step 3305 in FIG i.e., 306.

处理开始于步骤401。 Processing begins at step 401. 在步骤402,网络设备管理系统与网络设备建立基于会话的加密套接字层连接(SSL)。 In step 402, network device management system based on network devices establish a session connection Secure Sockets Layer (SSL). 网络设备管理系统具有网络设备的IP地址,因此能够通过该地址与需要管理的网络设备建立连接。 IP address of the network device management system having a network device, it is possible to establish a connection through the network device address to be managed.

在步骤403,网络设备管理系统向网络设备发送改变IOR (Interoperable Object Reference )请求,该请求中包括具有网络设备管理系统IP地址的网络设备管理系统IOR和用于表示网络设备管理系统的标识(Instance—ID ),该标识还可以用于区分本地和远端网 In step 403, the network device management system sends to the network device change IOR (Interoperable Object Reference) request, which includes the network device management system having a network device management system IP address and a flag indicating IOR network device management system (Instance -ID), the identification may also be used to differentiate between local and remote network

络设备管理系统。 Network equipment management systems.

在步骤404,网络设备从网络设备管理系统发送的Corba客户机IOR中提取与网络设备管理系统相关的信息,并对其进行检验以确认其是否合法。 In step 404, Corba client IOR network equipment sent from the network device management system to extract information related to the network device management system, and its test to confirm its legitimacy. 所检验的信息包括所述网络设备管理系统的标识(Instance—ID )、所述网络设备管理系统的IP地址、已经连接的网络设备管理系统的数量是否超过预订值等。 The test information includes identifying the network device management system (Instance-ID), the number of IP address of the network device management system, the network device management system has been connected exceeds the value like reservation. 在对IP地址进行检验时, 如果发现该IP地址已经与在网络设备连接,则检验失败,以保证一台网络设备管理系统只能有一个管理器对同一网络设备进行管理。 When tested on the IP address, if the IP address has been found in connection with the network device, the test fails to ensure that a network device management system can be only one manager on the same network device management.

在步骤405,网络设备判断连接请求是否通过了检验,如果通过了步骤404的检验,则处理转到步骤406,否则转到步骤409。 In step 405, the network device determines whether the connection request passed the test, if the test of step 404 passed, then the processing proceeds to step 406, otherwise, to step 409.

在步骤406,网络设备为网络设备管理系统分配一个新的标识(InvokejD),该标识用于表示该网络设备管理系统,并且在整个连接会话中存活,每次网络设备管理系统在发起操作请求时,请求中将包括该标识。 At step 406, the network device is a network device management system assigned a new identity (InvokejD), the identifier is used to indicate that the network device management system, and survived throughout the session connection, each network device management system initiates a request operation , the request will include the identification.

在步骤407,网络设备将在步骤406中所分配的标识和网络设备管理系统的IP地址存储在网络设备中的会话表(Session Table )中, 对配置数据进行更新。 In step 407, the network device stores the IP address allocated in step 406 and the identity of the network device management system in a network device in the session table (Session Table), the configuration data is updated.

在步骤408,网络设备通过在其中安装的Corba服务器端Servant 的IOR向网络设备管理系统返回由步骤406所分配的标识。 In step 408, the network equipment identified by step 406 by returning assigned to network device management system in which the IOR Corba server installed in Servant.

在步骤409,连接处理结束。 In step 409, connection processing is terminated.

通过以上操作,网络设备和网络设备管理系统建立连接,之后网络设备管理系统定期向网络设备发送存活检测(Health check)以验证连接的有效性。 By the above operation, the network device to establish a connection and network device management system, after the network device management system periodically transmits survival detector (Health check) to verify the validity of the connection to the network device. 如果网络设备接收到存活检测,则该网络设备向网络设备管理系统发送应答信息以告知其连接有效。 If the network device receives the detection survival, the network device sends a reply message to inform the network device management system which is connected to valid.

如在步骤311中所述并结合上文参照图9的描述,如果网络设备收到与其连接的多个网络设备管理系统之一发出的专用模式转换请求,则网络设备断开与其它网络设备管理系统的连接。 As in step 311 described above in conjunction with reference to FIG. 9, if the network device receives one of the plurality of dedicated mode, the network device management system connected thereto conversion request issued, the device disconnects the network management and other network devices system connection. 因此,尽管其他网络设备管理系统仍继续发送存活检测,但却得不到网络设备的应答。 Thus, while the other network device management system continues to send survival test, but did not meet the response network devices. 在发出存活检测后,如果经过一定时间仍未收到应答, 则网络设备管理系统认为与该网络设备的连接已经断开,从而释放为该网络设备分配的资源上下文。 After issuing the survival test, if after a certain period of time have not received a response, the network device management system considers the connection to the network device has been disconnected, freeing resources context for the network equipment distribution.

如上所述,网络设备的工作模式可以通过与之连接的网络设备管理系统来设定,也可以由其本身进行改变。 Mode of operation described above, the network device may be set by the network device management system connected thereto, may be changed by itself. 当网络设备处于专用模式下时,如果网络设备管理系统断开与该网络设备的连接,则该网络设备自动转入只读模式。 When a network device in a dedicated mode, if the network device management system is disconnected to the network device, the network device automatically into read-only mode. 当网络设备处于只读模式或共享模式下并且有多个网络设备管理系统与其连接时,为了便于本地网络设备管理系统的调试工作,在一些实施例中可以只允许本地网络设备管理系统指示网络设备转入专用模式。 When the device is in read-only mode or the network mode and a plurality of shared network device management system connected thereto, in order to facilitate debugging of the local network device management system, in some embodiments, may only allow local network device management system indicating the network device into a special mode.
