![]() ![]() In our experiments, we achieved a drop of 28% on processor energy use for a constant throughput scenario when comparing with the single-core approach. Higher energy efficiency is achieved by a parallel implementation of the controller and lowering each core’s frequency of operation. We performed experiments based on standard network measures, namely latency and throughput, and standard energy efficiency metrics for data centers such as the Communication Network Energy Efficiency (CNEE) metric. We show that a multicore controller can use an off-the-shelf multicore processor to save energy while keeping the level of service. By dividing the tasks among homogeneous cores, one can lower the frequency of operations, lowering the overall energy consumption while keeping the same quality of service level. ![]() It takes advantage of the parallel processing capabilities of modern off-the-shelf multicore processors to split the many tasks of the controller among the cores. This paper proposes a novel approach to energy efficiency focused on the network’s control-plane, which is complementary to the many already existing data-plane solutions. These strategies reduce energy consumption at the expense of processing power of the controllers. On the control-plane, researchers have found algorithms for positioning the controller in a way to reduce the number of used links, thus reducing energy. Many researchers have tackled this issue using existing routing techniques to dynamically adjust the network forwarding plane to save energy. This growth comes with a cost of more processing power and energy consumption. The programmability of these networks is a great feature that allows innovation to be deployed fast, following the increasing number of new applications. SDN is made possible by separating the control plane from the forwarding/data plane.Software-defined networks have become more common in data centers. SDN technology enables IT administrators to configure their networks using a software application, instead of changing the configuration of physical equipment. Software-defined networking (SDN) is a method for managing and configuring networks using software. Network topology is like the way that the roads are arranged, and the computing devices within the network are like the destinations that those roads lead to. Again, think of the stoplights that function at the intersections of a city. The control plane establishes and changes network topology. Network topology refers to the way data flows in a network. Intermediate System to Intermediate System (IS-IS).Enhanced Interior Gateway Routing Protocol (EIGRP).What protocols do routers use to create their routing tables? Meanwhile, the data plane (or the forwarding plane) is more like the cars that drive on the roads, stop at the intersections, and obey the stoplights. Think of the control plane as being like the stoplights that operate at the intersections of a city. The data plane is also called the forwarding plane. In contrast to the control plane, which determines how packets should be forwarded, the data plane actually forwards the packets. ![]() What is the data plane? What is the forwarding plane? Routers use various protocols to identify network paths, and they store these paths in routing tables. The process of creating a routing table, for example, is considered part of the control plane. The control plane is the part of a network that controls how data packets are forwarded - meaning how data is sent from one place to another. The term is used in the sense of "plane of existence." The two most commonly referenced planes in networking are the control plane and the data plane (also known as the forwarding plane). In networking, a plane is an abstract conception of where certain processes take place.
