....a declarative language for modeling network con guration and operation for fault analysis where the emphasis was on deducing the cause of failures that have occurred by tracing the propagation of operational rules in the model. Constraint based management has been pursued previously in [10] and [11] where constraints are employed for the diagnosis of network faults. In the area of con guration management automation, the GeNUAdmin system[6] is an o line tool for extracting network con guration information into a centralized database, performing updates on that database which are checked ....

.... been applied to routing to solve bandwidth allocation planning [Frei Faltings, 1999] and QoS based multi domain routing [Calisti Faltings, 1999] In our work, we have extended the problem domain to encompass fault management of Internet network services [Sabin, Russell, Freuder, 1997] [Sabin et al. 1999] . At the center of constraint technology lies the concept of the constraint satisfaction problem (CSP) Freuder Mackworth, 1994] A CSP is defined by a set of variables, a set of value domains, and a set of constraints. Each variable has an associated domain of values that can be assigned to ....
....database. The main goal of this project is to enhance SPECTRUM s management capabilities with constraint based reasoning techniques. This work is a direct extension of previous results from diagnosing problems with Internet network services, such as FTP and DNS [Sabin, Russell, Freuder, 1997] [Sabin et al. 1999] . The example considered in this paper is a simple local area network monitored with SPEC TRUM management tools. The network manager provides sets of specifications which are used to synthesize a constraint representation of the network configuration. This is used to automatically build a ....

....and diagnose special classes of randomly generated circuits (El Fattah Dechter 1992) Riese 1993) employs constraints to model and diagnose communication protocols. In our work, we have extended the problem domain to encompass management of network services (Sabin, Russell, Freuder 1997) (Sabin et al. 1999). Our contribution in this application domain includes: 1) modeling network services, 2) detecting and isolating faults with the network services, and (3) proactive diagnosis and explanation support. With our approach, we model the network service as a CSP. A CSP contains variables with ....
.... Freuder 1996) The composite CSP representation has the advantage of facilitating modeling of complex systems by supporting composition, local models, and parameterized relationships or ports. A more detailed application of composite CSP to modeling replication groupware service can be found in (Sabin et al. 1999). In Figure 1 we show a simplified part of the DNS resolution model. It contains variables (drawn within rectangles) composite values (drawn within ovals) and one constraint, on variables remoteHost and hosts. The constraint asks for the name of the remote host to be listed in the hosts file on ....
