Abstract This draft presents a LDAP schema for the DMTF CIM Network model version 2.2 [4]. 1. Introduction This draft presents a LDAPv3 [1,2] schema for the DMTF CIM Network model. Associations are mapped using a combination of auxiliary classes and DIT structure rules. Where auxiliary classes are used, name form and DIT content rules are specified. This document is not a product of the DMTF, and represents the view of the authors. Expires 6/30/00 [Page 1]
INTERNET DRAFTLDAP Schema for the DMTF Network CIM v2.2 ModelDecember 1999 2. LDAP Mapping Considerations 2.1 Differences Between this Mapping and the CIM Device Model There are some differences between the classes and associations specified in the CIM model and the schema here. First, because the core model requires services to be contained by systems the NetworkServicesInAdminDomain association doesn't add any new information. Second, there are a couple of classes that don't have structural rules specified for them as they don't specify any new RDNs. There are a couple of namespace collisions between this model and and other models, a couple of attributes in this model have been renamed. Finaly, the classes TransparentBridgingStatistics, SpanningTreeStatistics, SwitchPortStatistics, SwitchPortTransparentBridingStatistics, SwitchPortSpanningTreeStatistics, SwitchPortSourceRoutingStatisitcs, BGPStatistics, and BGPServiceStatistics aren't included as they contain counter information that is considered too dynamic for directory storage. 2.2 Changes to cimAssociationInstance The core mapping [3] defined cimAssociationInstance as a helper class. To support the auxiliary classes, the following classes should be added to cimAssociationInstance's content rule: Also, the following structure rules defined here need to be added to the structure rule for cimAssociationInstance: 3. Class Definitions For efficiency in the LDAP representation, associations are specified as a combination of auxiliary classes and DIT structure rules. Attribute definitions for each class are presented with the object class. Other definitions are also provided when necessary. This approach minimizes the number of DN pointers stored in the schema, but some pointer dereferencing is necessary. While not explicitly stated in the definitions below, we assume that all attributes with DN support the matching rule defined in [3]. Attribute names for DN pointers also follow the convention that a single pointer's name ends in "Ref", while an array of pointers' name ends in "Refs". Note: all attribute, object class, and name form OIDs are place holders, and syntax OIDs in definitions have been replaced by names for clarity. Expires 6/30/00 [Page 2]

On the other hand, services that provide quality of service (e.g., DiffServ) and security (e.g., IPSec) do affect the traffic stream.

The following are the most popular: "Aggregate only", where only the aggregate is advertised, and all of its more specific routes are suppressed; "Aggregate Plus Specific Routes", where both the aggregate as well as its more specific routes are advertised (e.g., send the aggregate to the NAP, but send the more specific routes to providers); "Aggregate Based on a Subset of Specific Routes", where the aggregate route is formed by looking at certain more specific routes and forming an aggregate on them, suppressing all others.'
