“…Based on the in-band control plane, they could also implement load balancing and fast failure recovery. Suo et al [6] devise a new in-band control plane called ERIC, a hybrid-band scalable control designed for DC networks. They use pre-computed rules installed in the switches, both for the initial bootstrapping and in case of link failures or network congestion; however, they do not provide further details about it.…”

“…On the other hand, the channel is in-band when physical links are shared between the control and data planes and no additional links are required. Additionally, hybrid-band control is defined when some links are shared but, at the same time, dedicated links for control also exist [6], as in the example shown in Figure 2. Each type of deployments has its own advantages [6], and the selected approach mainly depends on the network scenario [7][8][9].…”

Some of the disadvantages of out-of-band are advantages of in-band and vice versa, while hybrid-band could be considered a trade-off among both approaches.…”

Software-Defined Networking (SDN) is a thriving networking architecture that has gained popularity in recent years, particularly as an enabling technology to foster paradigms like edge computing. SDN separates the control and data planes, which are later on synchronised via a control protocol such as OpenFlow. In-band control is a type of SDN control plane deployment in which the control and data planes share the same physical network. It poses several challenges, such as security vulnerabilities, network congestion, or data loss. Nevertheless, despite these challenges, in-band control also presents significant opportunities, including improved network flexibility and programmability, reduced costs, and increased reliability. Benefiting from the previous advantages, diverse in-band control designs exist in the literature, with the objective of improving the operation of SDN networks. This paper surveys the different approaches that have been proposed so far towards the advance in in-band SDN control, based on four main categories: automatic routing, fast failure recovery, network bootstrapping, and distributed control. Across these categories, detailed summary tables and comparisons are presented, followed by a discussion on current trends a challenges in the field. Our conclusion is that the use of in-band control in SDN networks is expected to drive innovation and growth in the networking industry, but efforts for holistic and full-fledged proposals are still needed.

“…By summarizing previous studies and implementations, we deem that the biggest challenge of the SDN in-band network is how to promote the QoS of in-band control traffic. To overcome this challenge, researchers have proposed several solutions, such as, setting high priority queue for control traffic [8], adding the number of in-band connecting points [9] and adopting MPTCP to in-band control traffic [10], [11]. All these researches make great contributions to improving QoS of in-band control traffic.…”

In SDN architecture, the control channel between the control and data planes is extremely significant, which has two connection modes: out-of-band mode and in-band mode. For in-band mode, the key to the establishment of SDN control channel is how to forward in-band control traffic in the data plane (control traffic: traffic between controllers and switches). In almost all the existing implementation of the in-band SDN networks, the forwarding of in-band control traffic in the data plane depends on distributed Layer 2 switching that cannot respond to the network state change immediately. In this article, we propose a Centralized Trust-based In-Band (CTIB) control mechanism for SDN in-band control channel. Then based on CTIB control mechanism, we design CTIB routing algorithm to select the most trusted control path for each data plane switch in order to improve the QoS (Quality of Service) of in-band control traffic. Furthermore, we implement CTIB control mechanism in an in-band SDN network and carry out several experiments to test the QoS of the in-band control traffic. The results indicate that there is a huge improvement of in-band control traffic QoS when using CTIB control mechanism compared to the distributed Layer 2 switching. INDEX TERMS SDN, centralized in-band controlling, QoS of in-band control traffic, trust-based routing.
