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)
PrototypeDNS Service Deployment
PrototypeResults
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
