“…The notion of everything defined by software has evolved from theory to practice, which has allowed software-defined technologies to flourish, such as software-defined forwarding (SDF) [13], software-defined interconnection (SDI) [14], software-defined hardware (SDH) [15], software -defined protocol (SDP) [16], and software-defined chips (SDC) [17]. The above technologies can define topologies, protocols, hardware and software, and interfaces of basic networks in all dimensions, so as to provide diversified and personalized applications with fine-grained and definable network components and services.…”

In this paper, we explore potential innovations that could lead to breakthrough developments in Internet technologies. The deep integration of the Internet and economic society brings professionalized service capacity demand, while existing Internet infrastructure with its current technological systems still face a number of challenges, such as intelligence, diversification, personalization, robustness, and efficiency. First, we analyze the actual foundation of innovation and specify the basic technical features of a novel network. Then, we propose a fully dimensionally definable open architecture as the primary direction, and consider reshaping baseline technologies as a starting point and discuss the core operational mechanisms of the novel network based on such reshaped baseline technologies.

“…The protocol-dependent and compatibility issues induced by OpenFlow can be resolved by leveraging the efforts made to realize protocol-independent forwarding (PIF) [23]. More specifically, by incorporating protocol-oblivious forwarding (POF) [16] in the NVH system, we realized SR-PVX in [8], which allows tenants to customize the packet forwarding behaviors in their vSDNs in an arbitrary manner.…”

“…1 and is developed based on the well-known ONOS platform [15]. By following our previous idea in [8], we first expand the NVH module in ONOS to add in the support of protocol-oblivious forwarding (POF) [16]. Hence, the programmability and flexibility of the NVH system can be significantly improved to accomplish protocolindependent vSDN slicing.…”

In this paper, we design and implement a distributed network virtualization hypervisor (NVH) system, namely, DPVisor, which can provide superior network programmability based on protocol-oblivious forwarding to realize highly-available, scalable, and protocol-independent virtual software-defined network slicing. The experimental comparisons indicate that DPVisor achieves comparable performance as ONVisor (i.e., an OpenFlow-based ONOS benchmark), in terms of the message processing latency, message processing throughput, and failure recovery time. Moreover, to optimize the performance of the distributed NVH systems, we carefully adjust the consistency model used in the state synchronization of NVH instances and propose a local cache-based scheme to balance the tradeoff between the consistency and availability of network status. Our experimental results confirm that the message processing throughput of the distributed NVH systems can be greatly improved (i.e., for both DPVisor and ONVisor), while the data consistency among NVH instances is still maintained well.INDEX TERMS Software-defined networking (SDN), network virtualization, distributed network hypervisor, consistency model, protocol-oblivious forwarding (POF).
