  14. Features; more • Supports vendor specific objects through code-generation • Support Client/Server connectivity through • High performance TCP/IP • RMI/CORBA • 고객의 요구에 부응하여 빠른 시간내의 개발이 가능(e.g Nortel 개발기간 75%단축) • Developer Tools; Nar, Config Checker, Deployment Wizard, MIB Browser, Patch Manager, ObjectToRelational Tool, Trap/Event/Alert Filter, Trap/Event Parser, etc.

  15. Studies By Nortel 80% Saving 75% Saving AdventNet Enables a Quantum Leap in Implementation Productivity of Its Partners Our Mission: Enable Our Customers’ Success • Our engineers become a virtual R&D extension to your team during your implementation • Studies by Nortel point to a substantial improvements in • productivity and • time-to-market • enabled by AdventNet

  16. WebNMS 개발과정1 MOC작성 • MIB을 기반으로 관리하고 자하는 객체의 MOC정의. • AdventNet에서 제공하는 MO들을 상속 받아 구현. • 관리하고자 하는 User Property를 단순히 추가만 하면 됨. • MOC(Managed Object Class) : Java Object to represent the Network Elements(AtmSwitch, Shelf, Slot, Card, Port, etc.) • MOI(Managed Object Instance) : real managed Network Elements created by MOC

  17. MOC정의 • MOC : AtmSwitch, Card, Port를 표현하는 Java Object • MOI : MOC에 의해 생성된 여러타입의 객체 인스턴스들

  18. Topology DB Objects

  19. MOC작성 예제 public class AtmSwitch extends SnmpNode implements ContainerInterface { public AtmSwitch() { setType("AtmSwitch"); setClassname("AtmSwitch"); setPollInterval(300); } private String atmSwitchId = "atmSwitchId"; public void setAtmSwitchId(String atmSwitchId){ this.atmSwitchId = atmSwitchId; } public String getAtmSwitchId(){ return atmSwitchId; } } AtmSwitch Shelf Slot Card Port

  20. WebNMS 개발과정1 DataBase Schema자동생성 • 작성되어진 MOC를 기반으로 ObjectToRelational Tool을 • 사용하면 DatabaseSchema및 query문까지 자동생성. • OIDType.data에 관리되는 객체의 sysObjectID등록.<DATA OIJ=“.1.3.6.1.4.9.5.18” • TYPE=“ cisco Catalyst’” • POLL_INTERVAL=“600”/> • Discovery filter를 사용하여 원치않는 type을 filter out. Discovery Configuration Status Polling • 사용자정의의 Polling 추가시 UserTester Interface를 구현. MOC작성 • MIB을 기반으로 관리하고 자하는 객체의 MOC정의. • AdventNet에서 제공하는 MO들을 상속 받아 구현. • 관리하고자 하는 User Property를 단순히 추가만 하면 됨.

  21. WebNMS 개발과정2 • 동적인 Custom Map 생성. • Map filter를 사용하여 원하는 형태의 Layout및 Sub-map • 생성. • 메뉴화일(XML)의 Configuration 이 용이하고, User가 • 작성한 GUI화면을 쉽게 Integration 할 수 있다. MapConfiguration • Trap/Event Parser의 단순한 setting만으로 enterprise • Trap처리. • 특정 Event/Alarm에 대한 Action설정 (e.g. E-mail ) Trap Configuration

  22. Trap Parser

  23. Event Filter

  24. Database Module • Flat-file, RDBMS • 100 database transactions per second on 450 MHz/256 Mb Pentium machine • many databases engines – Oracle, Informix, MySQL, SQLAnywhere, Cloudscape and others

  25. Protocol Module • Northbound, southbound SNMP 지원 • multiple interface extension and connectivity through CORBA, JAVA, RMI, XML, etc. • Enables flexibility to integrate with OSS or upper manager

  26. Management Server Module • Consists of set of modules • Run either as stand-alone processes or, • Bundled threads in single process • Modules functionality includes • Auto-Discovery • Event Management • Topology • Device Management • Report Management • Polling Engine • Communication Layer • Database Interface Layer

  27. Management Server Module • Modules functionality can be customized to meet user needs • Web NMS is highly scalable, supports up to 100,000 MOs per server • Includes configuration server for applying configurations to devices and the MO database • Evolving to an XML based stateless session model, with multi-protocol support

  28. Communication Module • Web NMS supports industry standard Web Servers – Apache, Netscape, JAVA Web Server, IIS • Servlet support for HTML, JAVA GUI • Web NMS Client session manager modules are separate from the functional modules • Scalability to support large number of clients

  29. Client Module • Modular architecture enables Web NMS to support HTML, JAVA applets or JAVA application clients. • Web NMS provides easy of use tree based GUI, with plug-in panels for functionality • Panels can be customized to meet user specified behavior models. • GUI support common facilities such as right-click, pull-down menus, keyboard shortcuts, etc. • Web NMS GUI requires no user installation for HTML or JAVA applets clients • Enabling causal usability

  30. Fault Management • Reporting • Displaying events/alarms via tables, messages, etc • Events/Alarms summaries, Events/Alarm trees • Clearing events/alarm • Monitoring • Receiving and logging events/alarms • Acknowledge/unacknowledged events/alarms • Alarm Correlation • To avoid event flood • Support for Root cause analysis • Support Sorting and filtering through SQL engine • Configurable Severity and Threshold

  31. Configuration Management • Configuration server module • Apply changes via XML to devices and database simultaneously • Device Provisioning • Real-time and pre-provisioning through MIB browser • User definable default provisioning template • Support device-level status and control • Support Inventory Management

  32. Performance Management • PM threshold setting and monitoring • PM usage measurements • PM reporting based on user configuration • Policy driven administration • PM historical data • Current and archived

  33. Security Management • User/password protection • Client and Server levels • fine-grained access control • LDAP directory server based Authorization • Management functionality • Area management • audit trial for all security events • security through access-control method

  34. Topology • Support for Modeling Object Containment and Parent/Child Relationships • Automatic Discovery • Network-level • Device-level • Network Maps • Automatic map generation • Multi-level topology maps(object containment hierarchies) • Customizable menus to access functions, e.g. add/delete symbols or links, and to perform other actions • Transient map support for dynamic displays

  35. Product Benefits • Ease of development • Time to market; rapid development • Extensibility • Enables focus on higher value areas • Enables more functionality; pre-built application modules and tools • Reduces risk • Useful new technology evolution
