Dynamic Resource Allocation Based on Software Defined Networking

Abstract

Traditional IP networks are complex and very hard to manage. Software Defined Networking (SDN) is an emerging paradigm that promises to change this, separating the network’s control logic from the underlying routers and switches, promoting centralization of network control, and introducing the ability to program the network. SDN create and introduce new abstractions in networking, simplifying network management and facilitating network evolution. Quality of Service (QoS) deals with providing end to end guarantees to the users. These guarantees may include parameters like bandwidth and latency guarantees, packet loss, jitter, congestion control, etc. There are many ways in which such assurances can be obtained. On the control plane, a network operating system may exploit various services like prioritized scheduling, resource reservation, queue management, routing, etc. Configured data center network model that manage by one floodlight controller and connected to one OpenFlow switch by used Mininet simulation. Mininet software is emulated in order to evaluate the connectivity and performance of SDN networks parameters that indicate such as end to end delay, packets delay variation, and throughput are obtained and analyzed by using jperf tool to investigate that the SDN networks can meet the basic function. After analysis the results from SDN with bandwidth of 10Mb/s found that when starting to sending TCP as data stream between host1 to host3, the first bandwidth receiving when starting to send packet is 11.5Mb/while the data at end of transmission is 9.66 Mb/s with total interval of 10 sec. Transfer data between host1 to host2 when sending TCP packet, the first bandwidth receiving is 11.5 Mb/s while the data at end of transfer is 9.74 Mb/s with total interval of 10 sec. The result between host2 to host3 when sending TCP packet, the first bandwidth receiving when starting to send packet is 11.5Mb/while the data at end of transfer is 9.66Mb/s with total interval of 10 sec. When sending UDP as data stream between host1 and host3 the first bandwidth receiving when starting to send packet is 1.07Mb/s while the data at end of transfer is 1.05Mb/s received with jitter of 0.05 ms with total interval of 10sec. The result between host1 to host2, the first bandwidth receiving when starting to send packet is 1.24Mb/s while the data at end of transfer is 1.05Mb/s with jitter of 0.04 ms with total interval of 10 sec. The final result of sending packet between host2 to host3, the first bandwidth receiving when starting to send packet is 1.07Mb/s while the data at end of transfer is 1.06Mb/s received with jitter of 0.09 ms with total interval of 10 sec.
