## 5 Conclusions  
The primary contribution of this study is the combination of SDN with NDN. It centered on three things. First, we designed the SDPCACM for NDN that addressed consumer mobility issues by extending new features to the NAR, such as pre-fetching and proactively caching contents on behalf of the consumer, in which the controller of the SDN maintains the network information for network topology to forward the updated routes in the handoff/handover situations. Watching a real-time video in a state of mobility that changes position from one access point to another, the controllers in the SDN preserve the network layout and topology. They also link metrics to transfer updated routes with the occurrence of the handoff or handover scenario, and through the proactive caching mechanism, the previous access router proactively sends the desired packets to the new connected routers which reduces the handover delay time. Secondly, this study described the intra- and inter-domain handover handling management scenarios for SDPCACM with respect to NDN to sustain routing stability with the existence and presence of consumer mobility, as well as to efficiently control consumer mobility and request stuffiness issues in order to decrease the loss of interest as well as the hand-off delay for a data packet. Thirdly, this paper provides examples of parameter settings for an ODL controller, OpenFlow switches, and virtual machines (VMs). This research offers exemplary techniques and parameter settings for OpenFlow switches, ODL controllers, and virtual machines (VMs). In addition to addressing problems like connection loss due to handoffs, incomplete data receipt, packet transmission delays, etc., this research also addresses benefits like flexibility, scalability, programmability, dynamic allocation of network resources, and centralized control. It also assists in meeting the NDN's performance and mobility management criteria. Additionally, it simulates the SDPCACM that is suggested for NDN. The experimental

and simulation result shows that our scheme has an improvement in results in terms of reducing handover delay time, increasing CPU usage, throughput, as well as reduction in jitter and packet loss ratio.
