Presentation OutlineIntegrated Network ManagementMiNSCEvaluationPrototypeConclusion

Integrated Network ManagementCommunication network’s increase

◦Size, diversity, functionality and complexity

Diversity of management solutions◦Protocols, languages, data models◦Highly complex network management

Translations◦Syntactic Translations – Limitations

Easily automated Overlapped concepts

Data inconsistencies and collisions ◦Semantic Translations – Limitations

Complex to implement Lack of formal semantic description Administrator dependency Complex for highly heterogeneous

management domains

MiNSCMiNSC’s New Management Model

◦Network Service Configuration Management

MiNSCMid-level Network Service

Configuration (MiNSC)◦Service management information models

based on the service’s standard definitions

◦Two management abstraction layers High and low management abstraction layers Active and Candidate nodes classification

◦Secure, reliable and efficient configuration management (SNMPv3 over TCP)

◦Overcomes the implementation of management translations

MiNSCMiNSC’s Two-layer Architecture

EvaluationTheoretical evaluation

◦Objectives: Integrated network management method Verify the support for larger scale

heterogeneous management environments◦Evaluated network management

frameworks: Cfengine WBEM FOCALE MiNSC

EvaluationHeterogeneity

◦Most frameworks support integrated network management based on management translations

◦MiNSC provides a different integrated network management supported by normalized solutions to overcome the translation mechanisms

Resilience & Scalability◦Most framework depend on centralized entities

(single point of failure)◦MiNSC Indirect instance’s configurations

replications

EvaluationInteroperability

◦Implementation of proprietary solutions Standard management information

models & management protocol SNMP + MIB

Summary

PrototypeDNS Service Deployment

◦Independent DNS management◦Automatic setup of a DNS domain

Specified models◦DNS Service management information

model◦DNS node management information model

DNS Servers modules◦Bind9 Linux (A)◦Bind9 Windows (B)◦Posadis MS Windows (C)

Conclusions◦Low variation with deployment heterogeneity◦Quick, secure and automatic DNS service

deployment

ConclusionWith MiNSC proposal

◦Simplifies the heterogeneous network service management

◦Different integrated management framework

◦Management interoperability is guaranteed

◦Overcomes the need for intermediary management translations

◦Service management automation◦Resilience & scalability concerns
