This research will analyze a series of IPv6 transition mechanisms over the Multiprotocol Label Switching (MPLS) backbone using a simulation tool (OPNET) and will evaluate and compare their performances. For the two protocols to coexist, various IPv6 transition mechanisms have been developed. IPv6 is acknowledged to provide more address space, better address design, and greater security however, IPv6 and IPv4 are not fully compatible. The testbed results are compared to those of simulations to precisely assess the model.Įxhaustion of current version of Internet Protocol version 4 (IPv4) addresses initiated development of next-generation Internet Protocol version 6 (IPv6). To assure the most comprehensive environmental evaluation of the model, 128 distinct scenarios are developed and implemented, and the results are obtained in terms of quality of service parameters. The model is further extended by setting up a real-world testbed environment to include four networks for replication of those simulations. The model consists of a simulation environment with four distinct networks: LTE-IPv6-only, LTE-IPv4-only, 802.11ac-IPv6-only, and 802.11ac-IPv4-only. To address the challenges associated with deploying IPv6-only in LTE and 802.11ac networks and quantify the performance, this work proposes a model. Therefore, there are increasing concerns for cellular carriers and mobile service providers regarding migration to IPv6-only and whether the users in LTE-IPv6-only and 802.11ac-IPv6-only networks can achieve better performance than IPv4. The issue is further increased along with the design complexities inherent in LTE and 802.11ac infrastructures.

However, while the full digital connectivity cannot be fulfilled by IPv4 due to its limited address space and failure to support the scalability of the IoT applications, another major problem is that the potential benefits of IPv6 for LTE and 802.11ac mobile networks are completely ambiguous.

To provide a large number of IP addresses, in addition to IPv4, LTE and 802.11ac also support IPv6. The long term evolution (LTE) and very high throughput (VHT) 802.11ac networks are among the alternatives that can fulfill the speed requirements. The presented empirical feasibility data includes network performance data such as: latency, throughput, packet loss, CPU load, and operational capability data, such as: configuration, troubleshooting and applications capability.įull digital connectivity of the Internet of Things (IoT) devices demands several requirements including high-speed networks and a large number of IP addresses. A suitable IPv6 transition implementation, covering multiple transition technologies, was tested in relation with this scenario.

The Enterprise needs to convey communication to IPv4 capable nodes through the IPv6-only infrastructure. The scenario was introduced by the IETF and it was dedicated to an Enterprise Network which is using IPv6 as backbone technology. The paper presents the overview of IPv6NET, the testing methodology and empirical results for a specific network scenario. As an answer, this article is proposing the IPv6 Network Evaluation Testbed (IPv6NET), a research project whose ultimate goal is to obtain feasibility data in order to formulate a coherent, scenario-based IPv6 transition strategy. One of these challenges is to decide which transition technology is more feasible for a particular network scenario. This transition has presented the Internet Community with numerous challenges. Behind this fact is the complicated transition period through which the Internet will have to go, until IPv6 will completely replace IPv4. IPv6 is yet to become more than a worthy successor of IPv4, which remains, for now, the dominant Internet Protocol.
