Recently, communication demands often change because of the various network services in companies and individuals. Software Defined Networking (SDN) has emerged as a viable control paradigm that allows flexible communication, using OpenFlow as its default standard and enabler. However, when changes happen frequently in SDN networks due to unforeseen reasons -such as a network failure or topology changes-it takes a long time to perform all the operations. For instance, to change a routing path, first new paths must be calculated, then the controller must transmit the commands to the network elements, which has to process those commands. This process can cause a delay, or even disruption, in the communication service. Therefore, this paper proposes a network control method to reduce the time to change a path using OpenFlow.

“…Then, the paths with the shortest switching time and the least bandwidth requirements are selected. The basic design was described in [1], and the preliminary simulation experiments presented in [11]. In this paper, the authors evaluate the effectiveness of the proposed method using emulated environments.…”

“…However, both schemes may experience higher flow table operation time thereby affecting path setup switching time. An effective method to minimize the total setup switching time of all paths in the network was presented in Gotani et al [31,32]. The authors considered path route selection based on path switching latency in heterogeneous networks, where switches had different specifications.…”

Route Path Selection Optimization Scheme Based Link Quality Estimation and Critical Switch Awareness for Software Defined Networks

et al. 2021

Software-defined network (SDN) is a new paradigm that decouples the control plane and data plane. This offered a more flexible way to efficiently manage the network. However, the increasing number of traffics due to the proliferation of the Internet of Things (IoT) devices also increase the number of flow arrival which in turn causes flow rules to change more often, and similarly, path setup requests increased. These events required route path computation activities to take place immediately to cope with the new network changes. Searching for an optimal route might be costly in terms of the time required to calculate a new path and update the corresponding switches. However, the current path selection schemes considered only single routing metrics either link or switch operation. Incorporating link quality and switch’s role during path selection decisions have not been considered. This paper proposed Route Path Selection Optimization (RPSO) with multi-constraint. RPSO introduced joint parameters based on link and switches such as Link Latency (LL), Link Delivery Ratio (LDR), and Critical Switch Frequency Score (CWFscore). These metrics encourage path selection with better link quality and a minimal number of critical switches. The experimental results show that the proposed scheme reduced path stretch by 37%, path setup latency by 73% thereby improving throughput by 55.73%, and packet delivery ratio by 12.5% compared to the baseline work.

“…In practice, achieving fast recovery would require faster solvers. In References [20,21], the authors considered the problem of path-switching latency in heterogeneous networks, where nodes had different specifications. The proposed method selected alternative paths based on the switches which had the shortest processing time.…”

There is increasing demand in modern day business applications for communication networks to be robust and reliable due to the complexity and critical nature of such applications. As such, data delivery is expected to be reliable and secure even in the harshest of environments. Software-Defined Networking (SDN) is gaining traction as a promising approach for designing network architectures which are robust and flexible. One reason for this is that separating the data plane from the control plane, increases the controller’s ability to configure the network rapidly. When network failure events occur, the network manager may trade-off the optimality of the achieved network reconfiguration with the responsivenss of the reconfiguration process. Responsiveness may be favoured when the network resources are under stress and the failure rate is high. We contribute SDN recovery methods that leverage information about the structure of the network to expedite network restoration when a link failure occurs. They operate by detecting community-like structures in the network topology and then they find alternative paths which have low operation and installation costs using this information. Extensive simulations are conducted to evaluate the proposed SDN recovery methods using open-source simulation tools. They provide evidence that the proposed approaches lead to performance gains when an alternative path is required among a set of candidate paths.
