RESUMO

Network performance measurements that cross different administrative domains are difficult to be obtained, due to use policy issues, security, etc. For these reasons, some national networks started efforts to allow the access to these types of measures, among them the Internet2, Géant2 and RNP. Given these efforts, it was created a document that defined and enabled the development of a prototype of a multi-domain network monitoring environment called perfSONAR. This prototype provided the necessary prerogatives to a broader access to network performance measurements of different administrative domains. To allow the use of the available measurements, many tools for access and visualization of network measurements were adapted or built to access perfSONAR data. However, few of these tools offer adaptability and reuse resources in their development, and those which did, made it without the use of a well accepted software reuse standard, that hamper the adaptation along the time and developed code reuse. Component-based software development is a well known discipline for a long time. It is based on the development of pieces of software that can be put together and composed to build applications. This discipline evolved to a distributed approach, which facilitates their distribution and deployment in a distributed network environment. There are many component models which follow this idea, like: EJB, CORBA, COM and OSGi. This work proposes a framework based on OSGi components to allow dynamic adaptation and easily reuse in network performance measurement access tools. It is being used in a network data visualization tool from RNP called Internet Computer network Eye (ICE), developed by the Measurement Working Group (GT-Medições) from RNP and in a video management environment developed by the Video Management Working Group (GT-GV), also from RNP.
