Pending Interest Table (PIT) in Named Data Network (NDN) maintains a track of forwarded Interest packets so that the returned Data packet can be sent to its subscriber(s). PIT size is a crucial parameter, which can have a huge impact on the number of both satisfied and timed out Interest packet, and consequently, on the number of packet delay in terms of PIT overflow. There are a lot of studies focusing on caching, applications, and security to make NDN getting perfect, while the management of PIT is still one of the primary concerns of high-speed forwarding. Thus, PIT manages mechanism is one of the most important design specifics that have not been studied in the context of NDN to a significant extent. NDN needs to define concise mechanisms to monitor traffic when multiple users contend for access to the same or different resources, which may lead the PIT is overflowing and as a result increasing the delay. In order that, the objective of this study is to provide an adaptive mechanism under network load, namely Smart Threshold Interest Lifetime (STIL) to adjust incoming Interest packet in the early phase of occurrence to propose possible response decisions to realize PIT overflow recovery. The ndnSIM network simulator was used to measure the STIL. The results demonstrate that the proposed mechanism outperforms the performance of standard NDN PIT with respect to average Interest lifetime, Interest satisfaction, Interest retransmission and Interest satisfaction delay. The significance of this study is to provide a fundamental direction of a new adaptive Interest lifetime mechanism in NDN router to decrease the delay, especially on the natural disaster in a city, which will be very much useful for emergency operation centers, emergency rescue teams, and citizens.

In Named Data Networking (NDN), Pending Interest Table (PIT) is proposed to record the forwarding information of interest packets forwarded but not responded. Each incoming interest packet or data packet needs to be queried and processed in PIT, and the overhead would rise as the scale of PIT increases. Therefore, PIT is required to have a very high processing speed. To effectively improve the forwarding efficiency of PIT in NDN, a new architecture of the PIT using a hot table to achieve prefix ...

Most of the services used by Internet consumers such as social network platforms, video-on-demand, on-line gaming, web Media, and IP Television which are content-centric in nature; meaning they focus on named content objects instead of being focused on the host-location. In this context, many projects around named data propose redesigning and developing the communication of Internet-based on named data. NDN (Named Data Networking) is an ideal solution to achieve efficient data sharing and retrie...
