“…Furthermore, the work in [14] attempts to solve the problem of link failures in hybrid scenarios, with coexisting SDN and legacy devices, applying machine learning-based policies. In this regard, the solution provided by eHDDP [5] allows the full discovery of hybrid SDN topologies by using a specific protocol in non-SDN devices that conveys all the topological information to the SDN control plane even if loops of non-SDN devices exist.…”

“…However, all previously mentioned protocols are strictly applicable to fully-SDN environments. For this reason, alternatives such as enhanced Hybrid Domain Discovery Protocol (eHDDP) [5] recently appeared to support hybrid SDN scenarios as a direct consequence of the inclusion of wireless and other heterogeneous network devices in the field. Nevertheless, the setup of SDN in-band control channels in hybrid SDN topologies still remains an open issue.…”

“…This article presents extended capabilities to our previous works Hybrid Domain Discovery Protocol (HDDP) [6], which is only suitable for wired networks, and eHDDP [5], which is suitable for hybrid wired/wireless networks, not only to convey topological information in hybrid SDN scenarios but also to establish SDN in-band control channels. Therefore, the proposal in this manuscript, ieHDDP, is capable of providing an integrated solution that allows effortless and plug-and-play use of SDN technology in any kind of scenario.…”

In-Band enhanced Hybrid Domain Discovery Protocol (ieHDDP) is a novel integral approach for hybrid Software-Defined Networking (SDN) environments that simultaneously provides a topology discovery service and an autonomous control channel configuration in the band. This contribution is particularly relevant since, to the best of our knowledge, it is the first all-in-one proposal for SDN capable of collecting the entire topology information (type of devices, links, etc.) and establishing in-band control channels at once in hybrid SDN environments (composed by SDN/no-SDN, wired/wireless devices), even with isolated SDN devices. ieHDDP facilitates the integration of heterogeneous networks, for example, in 5G/6G scenarios, and the deployment of SDN devices by using a simple exploration mechanism to gather all the required topological information and learn the necessary routes between the control and data planes at the same time. ieHDDP has been implemented in a well-known SDN software switch and evaluated in a comprehensive set of randomized topologies, acknowledging that ieHDDP is scalable in representative scenarios.

An Effective, Efficient and Scalable Link Discovery (EESLD) Framework for Hybrid Multi-Controller SDN Networks

The emergence of Software-Defined Networking (SDN) has revolutionised network management, offering improved flexibility, programmability, and scalability through the introduction of centralised controllers. Such a controller, e.g. an SDN controller, typically uses an OpenFlow discovery protocol to establish and maintain a global view of the topology in the underlying network. An accurate global view of the network topology is essential for effective routing, load balancing, and deployment of mobilitybased applications. However, in a hybrid multi-controller SDN network, the OpenFlow discovery protocol introduces repetitive operations, degrading effectiveness, efficiency, and scalability. This paper addresses this issue by presenting a novel link discovery framework for establishing and maintaining topology information in a hybrid multi-controller SDN network. The framework, named EESLD, uses an event-driven approach utilising the Bidirectional Forwarding Detection (BFD) protocol to detect direct and indirect SDN links in intra-domain and inter-domain networks. Additionally, EESLD uses the sFlow protocol to discover and monitor legacy links and employs a distributed messaging system to maintain a consistent network view across controllers. The EESLD framework has been implemented and evaluated on a Mininet emulator with an RYU controller and sFlow server. Performance evaluation results show that the EESLD framework can discover direct SDN links 10.3 times faster than OFDPv2, and indirect SDN links 12.9 times faster than BDDP in a network with 85 switches. Evaluation results also indicate that the sFlow-based link discovery outperforms the OSPF-based link discovery in legacy link discovery and removal times. These results show that the EESLD framework is a more effective, efficient and scalable solution for dynamic and large-scale hybrid multi-controller SDN networks.INDEX TERMS Software-Defined Networking (SDN), topology discovery, link discovery protocols, OpenFlow protocol, hybrid SDN, Multi-controller SDN.
