Adaptação de um Protocolo de Medição Ativa para Redes Tolerantes a Atrasos/Desconexões
Abstract
Delay/Disruption Tolerant Networks (DTNs) can be characterized by high delays and disconnections between the participating nodes. Despite these characteristics, DTNs need network management features similar to those found in conventional networks such as, for example, latency monitoring in message exchanges. One of the approaches commonly used for such monitoring is the use of standardized protocols for active measurements, such as, for example, the Two-Way Active Measurement Protocol (TWAMP). However, protocols like TWAMP are not prepared for DTNs because they consider conventional network environments, such as the Internet. This paper describes the Delay/Disruption Two-Way Active Measurement Protocol (DTWAMP), a proposal for the execution of active measurements in DTNs. In addition, experiments were performed to evaluate the proposed solution. The results demonstrate that DTWAMP has desirable properties to perform monitoring tasks in DTNs.
