RESUMO

In spite of the initiatives that appeared over the years in context of the IETF, some aspects related to con?guration and maintenance of systems currently developed for management of TCP/IP-based networks are still addressed in an adhoc manner. Some times, human intervention is needed, mainly during the occurence of parcial failures. This Thesis presents a study on utilization of JINI technology for building of those systems, in order to improve them for more ?exibility and self-resilience. The general considerations performed in this study point to: association of JINI Services to managed systems; grouping them in Managed Domains; incorporation of ?exible User Interfaces in their related proxies; utilization of security and transactions mechanisms provided by JINI on their communications with Management Applications; and deployment of both components into low computing power devices. In order to validate these considerations, two systems were developed. The ?rst one focus on the device level, being named Bay of Devices. The second, more scalable, has its focus on the wide-network level. This latter is an implementation of a PNMS that uses JINI for communication between the PMA and the PDP. It uses SNMP and the Event MIB for enforcement of Policies on PEPs. An alternative design for this PNMS is presented as well, showing the PEP as a JINI Service and performing such enforcement by means of remote method invocations on that component. Next, JINI is compared to other technologies used in creating revolutionary approaches (more speci?cally, CORBA and Web Services). That comparison, which includes the technology used on traditional approach as well, was performed taking into account the following parameters: modelling of applications, utilization of existent infrastructure and capabilities related to the utilization of ?exible User Interfaces and deployment of low computing power devices in these technologies. The results emerged from that comparison point to an equivalent, and sometimes better, suitability of JINI when compared to these technologies. This conclusion is due partially to its infrastruture, that also includes provision for using transactions. Moreover, auxiliary mechanisms allow users of JINI-based systems to manage devices and applications by means of ?exible and customized User Interfaces. Similar mechanisms allow its deployment on devices with lower computing power without loss of functionality. In fact, these features provide to JINI-based systems an unpreceeded level of ?exibility and automation on their operations. The future directions point to building of additional systems based on this technology, addressing aspects speci?c to devices and/or applications, and merging other technologies, when possible
