Request aggregation: the good, the bad, and the ugly

Request aggregation is a fundamental feature of named data networking (NDN). This feature aims to improve consumers' quality of experience and reduce network traffic by reducing content retrieval latency and eliminating redundant communication, respectively. However, the negative aspects of request aggregation have not been studied. In this paper, we inspect different facets of request aggregation and introduce one of its harmful behavior, which can create an implicit Denial of Service (iDoS) vulnerability.
