Information Model
Abstraction of IP networks
- Different views
- router complexes, router, physical (layer 2), abstract (for routing)
- Objects representing
- routers, links, and traffic demands
- Methods for manipulating objects
- finding and selection of objects
- linkage of objects, e.g., router complexes to routers
- statistics: histogram, tables, etc.
Salient features
- Captures important global network properties
- Supports routing simulation (e.g., change of OSPF weights)
- Trade off between accuracy and simplicity of model
