  Due to the popularity of network applications, such as multimedia, online
shopping, Internet of Things (IoT), and 5G, the contents cached in the routers
are frequently replaced in Content-Centric Networking (CCN). Generally, cache
miss causes numerous propagated packets to get the required content that
deteriorates network congestion and delay the response time of consumers. Many
caching strategies and routing policies were proposed to solve the problem.
This paper presents an alternative solution by designing a query-based routing
table update mechanism to increase the accuracy of routing tables. By adding an
additional query content in interest packets, our approach real-time explores
the cached content in routers and updated the routing table accordingly. This
paper uses a general network simulator, ndnSIM, to compare basic CCN and our
approach. The results show that our approach improves the response time of
consumers and network congestion and is compatible with general forwarding
strategies.
