This detailed introduction to all the integrated wiring system management software, for all this software may not be very understanding, this article will give a detailed answer to this software, from technical architecture to the main function, I believe you will read this PDSmanagement system software have a more profound understanding.
With the continuous improvement of degree of information technology, network transmission media continuously improve the performance of network transmission equipment, network management capabilities of the device is expanding.As the network forms the basis of: cabling system become more and more large and complex, this will inevitably lead to a structured cabling system administration requirements of specialization, standardization, increasingly demanding.
Manually based on the traditional management style can not be achieved with low maintenance costs, high efficiency management.To this end, the management of the cabling system is a continuous improvement process.Software, cabling management software, to implement the integrated management system for wiring a scientific and systematic management is very necessary, but also enhance the efficiency of integrated wiring system to protect the investment in structured cabling system the only way.
Cabling system based on current knowledge management software often associated with network management software, electronic patch panels and other vague understanding, it is focused to elaborate cabling management software with their differences.
The difference between the network management software
Integrated wiring systems management software is a system, sub-module is the physical form of the integrated wiring import graphical database.Then, on these devices, links, information points, the terminal-related person who has accurate, efficient, modifiable maintenance.In order to facilitate detailed analysis, the following will be generally familiar with the current domestic market of the Long Yuan Yan Shing Cabling System (CAMS V3.0) as an example.
Management software on the integrated wiring system software, network management software on the market today can be roughly divided into the following categories: network asset management, network monitoring, log analysis, routing, tracking, testing tools, network kits.Of course, this can also be classified according to: network management systems, application performance management, desktop management systems, employee behavior management, security management.Normally less likely to be integrated cabling management software and desktop management systems, employee performance management systems and security management systems to confusion.Therefore, we focus on to elaborate wiring system management software, the difference between CAMS and network management.
Network Management System (NMS) is mainly hardware devices for network monitoring, configuration and troubleshooting.Main features automatic topology discovery, remote configuration, performance parameters monitoring, fault diagnosis.Network management systems are usually developed by the two types, one is a universal software vendors, and the other is the various equipment manufacturers.
The development of common software vendor NMS system is network equipment manufacturers to address all the common network management system, quite popular with OpenView, Micromuse, Concord and other network management systems.
Various equipment manufacturers for their specific product design their own products NMS system monitoring, configuration is complete, some of the common network management system can monitor key performance indicators to monitor, there are some unique configuration.But on the other company's equipment is basically to do anything.Equipment manufacturers currently popular network management software has CiscoWorks2000, NetSight, domestic Linkmanage, iManager.
To discuss the following aspects from several specific differences:
(A), technology architecture
Integrated wiring systems management software to manage cabling system objects are based on WINDOWS, also based on UNIX / LIUNX, a stand-alone, there are B / S, C / S structure.As for development tools, and of course there are different, almost popular development tools can realize the relevant architecture.
However, not to say that a variety of platforms, different technologies, products will vary, because the ultimate aim is the same management.Therefore, we can say that cabling management software, the basic development framework should be integrated wiring system for object-oriented development process.
Integrated wiring system management software software CAMS example: Based on B / S architecture, object-oriented development, relational database, can be based on Oracle database, also can be based on other databases such as SQL SERVER.
The network management system is the most important part of the network management protocol, which defines the network manager and the managed method of communication between agents.
Generated in the network management protocol for a long time before, the managers have to learn a variety of network equipment from different data acquisition methods.Because each manufacturer uses proprietary methods to collect data, the equivalent equipment, manufacturers provide different data collection methods may be quite different.In this case, the urgency to develop an industry standard is increasingly evident.
First began to study the problem of network management communication standard is the internationally best-known International Organization for Standardization ISO, their network management standardization work started in 1979, mainly for the OSI (Open Systems Interconnection) seven layer protocol transmission environments.
ISO resulted in the CMIS (Common Management Information Service) and CMIP (Common Management Information Protocol).CMIS support management processes and communication requirements between the management agent, CMIP is to provide management information transmission service application layer protocol, the two provisions of the OSI network management system standards.OSI standard products are based on AT & T's Accumaster and DEC's EMA, etc., HP's OpenView is initially designed by OSI standards.
Later, Internet Engineering Task Force (IETF) to manage the geometric growth of the Internet, decided to use the CMIP protocol based on OSI management protocol as the Internet, and it was revised, the revised protocol is called CMOT (Common ManagementOverTCP / IP).However, due to the delay in the introduction of CMOT, IETF decided to have the SGMP (Simple Gateway Monitoring Protocol) and further modified as a temporary solution.Developed on the basis that the SGMP solution is well-known SNMP (Simple Network Management Protocol), also known as SNMPv1.
SNMPv1 biggest feature is the simplicity, easy to implement and low cost.In addition, its features include: Scalability - SNMP can manage most of the standard equipment meet the Internet; Extensibility - by defining the new "managed objects", can easily extend management capabilities; "robust"(Robust) - Even in a managed device when critical errors occur, it will not affect the manager's work.
In recent years, SNMP has developed rapidly, beyond the traditional TCP / IP environment, subject to more extensive support and become de facto standards for network management.Products support SNMP is the most popular IBM's NetView, Cabletron's Spectrum and HP's OpenView.In addition, many other production network communications equipment manufacturers, such as Cisco, Crosscomm, Proteon, Hughes, also provide SNMP-based implementation.Relative to the OSI standard, SNMP simple and practical.
As TCP / IP protocol stack, the other agreements, the beginning of SNMP security issues not considered, for many users and vendors made changes SNMPv1, increase the security module requirements.Thus, IETF began in 1992 to the development of SNMPv2.Planned second edition will enhance the safety and more effective management information to improve delivery, specifically including the provision of authentication, encryption, and time synchronization mechanism and operation of a one-GETBULK the ability to retrieve large amounts of data.
Simple Network Management Protocol (SNMP) has become the de facto standard network management protocol.SNMP is the IETF as the first research group to address in Internet management issues on the router, so many people that run SNMP in IP due to Internet running TCP / IP protocol, but in reality, SNMP is designed toand protocol independent, so it can be IP, IPX, AppleTalk, OSI, and other transport protocols used to use.
SNMP is a protocol consisting of groups and specifications, they provide a device from the network to collect network management information.
Therefore, the technical architecture, network management system is based on SNMP, which integrated wiring systems management software with integrated wiring system for a totally different development environments and development methods.
(B), the main function
In the functional areas:
CAMS, can involve a variety of equipment, cabling, transmission media, information terminal management, management is visual, the link-based relationship management.From the expansion of the function, it can also achieve asset management, aggregate statistics, random sampling queries, fault maintenance, document information, the trial record management, user management, standard operation.
Network management software, network topology search function, however, for specific technical details, we must consider specific agreements tailored to the search, otherwise, the case in the presence of VLAN, prone to search is not complete, of course, different productsPerformance is not the same.Custom device configuration.According to the needs of different users to define different strategies, but also with different network management software to achieve more matching network specification and management.
(C), the user needs
CAMS, integrated wiring system for information about content management.Can solve the user's daily time-consuming and inefficient document management queries; to resolve individual user information from the link between the failure to locate the difficulty; can be resolved when the user in the deluge of information, management, the orderliness of human action; cansolve the user on the network equipment, patch panels, cables, terminal statistics and random queries.
Network management software, network management, the most important thing is for monitoring network equipment, configuration, fault diagnosis, the user can solve the network layer and above the level of management, such as routing, switching the port monitoring, diagnostic equipment, such as the connectivity.However, it is clear the link between the graphics, visualization is not clear enough, but not to the management of structured cabling system to implement a complete information of the process.
(D), applications
CAMS, applications and integrated wiring system, all equipment, cables, terminal management, the core is a relational database of links to solve management problems, innovative management methods; network management software, the professional tool for network administrators, is adiscovery and technical tools to solve the problem, not an integrated wiring system management tools.
(E), not replace the relationship between each other, but mutually complementary relationship
CAMS obviously can not do the configuration of network routing equipment and monitoring, nor a relationship with the network protocol, but the link can be made on the data of the physical storage, so that cabling system management more efficient.
Network management software, because it is based on TCP / IP, SNMP under the agreement, therefore, can penetrate into the network, network equipment, operating parameters and status management.Is a network management process, one aspect of a technical tool, obviously no substitute for CAMS on the management of the entire cabling system.
For now, integrated wiring systems management software for the management, CAMS is necessary; and specific settings for network planning and operation, network management software tools is an inevitable choice.Management of these two software systems are necessary, although the starting point is the CAMS system management, daily management is the standardization of the network; and network management software is specific for each specific management tools.
