Abstract Software Defined Networking (SDN) is a novel architecture that separates the data plane from the control plane using an external controller. Similar to traditional networks, load balancing has a great impact on the performance and availability of SDN. Therefore, the Controller Placement Problem (CPP) in SDN influences on the load balancing solutions. In this paper, various topologies of CPP including different load balancer controllers are simulated and evaluated in the SDN using the OFSwitch13 module of ns-3 network simulator. The results provide a solid comparison of the proposed topologies in different network situations.

ABSTRAKJumlah pengguna yang meningkat merupakan salah satu penyebab menurunnya kualitas jaringan jika hanya menggunakan ukuran bandwidth yang sama. Sebagai contoh pada implementasi jaringan kampus, jaringan LAN antar gedung yang berbeda biasanya dihubungkan dengan menggunakan perangkat switch. Penurunan performansi jaringan pada jaringan tersebut akibat pertambahan jumlah pengguna bisa diatasi dengan menggunakan konsep load balancing dengan memanfaatkan teknologi EtherChannel. Implementasi teknologi tersebut dapat menggunakan dua pilihan protokol yaitu PAgP dan LACP. Penelitian ini bertujuan untuk menguji performansi jaringan yang menerapkan konsep load balancing dengan menggunakan protokol PAgP dan LACP. Skenario pengujian menggunakan konsep client-server, dimana aplikasi server yang digunakan adalah FTP untuk implementasi layanan pertukaran data dan penggunaan software VLC untuk implementasi layanan video streaming. Pada penggunaan layanan FTP dengan protokol PAgP dihasilkan nilai delay 42% lebih baik dibandingkan dengan LACP. Begitupula untuk nilai throughput, penggunaan protokol PAgP masih lebih baik 10% dibandingkan dengan LACP.Kata kunci: LAN, Load balancing, Etherchannel, PAgP, LACP ABSTRACTThe increasing number of users is one cause of declining network performance if only use on the same bandwidth value. For example, in the implementation on the campus network, LAN among different building is usually connected using a switch. The decreasing of network performance on that network due to the increasing of the number of users which can be overcome by using a load balancing concept with EtherChannel technology utilization. The implementation of that technology uses two protocols, namely PAgP and LACP. This research intends to test the network performance by applying the load balancing concept using both PAgP and LACP protocols. The experiment scenarios used a client-server concept, where the implemented application server is FTP for exchanging data services and VLC software for implementing video streaming services. In the use of FTP services with using PAgP protocol showed a delay value of 42% better than LACP. The same with throughput value, the use of PAgP protocol still better 10% than LACP.Keywords: LAN, Load balancing, Etherchannel, PAgP, LACP

Due to the increase in the number of users on the internet and the number of applications that is available in the cloud makes Data Center Networking (DCN) has the backbone for computing. These data centre requires high operational cost and also experience the link failures and congestions often. Hence the solution is to use Software Defined Networking (SDN) based load balancer which improves the efficiency of the network by distributing the traffic across multiple paths to optimize the efficiency of the network. Traditional load balancers are very expensive and inflexible. These SDN load balancers do not require costly hardware and can be programmed, which it makes it easier to implement user-defined algorithms and load balancing strategies. In this paper, we have proposed an efficient load balancing technique by considering different parameters to maintain the load efficiently using Open FlowSwitches connected to ONOS controller.

In today’s age of digital media and social networks, delivering content to a massive scale of recipients became one of the main challenges. Load Balancers and Content Delivery Networks are used to distribute content to multiple locations, which increase the scalability of services and decrease the load on content origins. Both technologies rely on redirections. Redirections have not received a significant amount of attention in the recent years; however, they do impose some limitations. In this article, we propose a transparent redirection mechanism, which exploits the versatility of Software Defined Networking. The redirection method is achieved by handing off existing TCP sessions without any required modifications to the endpoints. This article demonstrates how the proposed redirection mechanism can be adopted in Content Delivery Networks and Load Balancing scenarios. The performance of the solution is thoroughly tested and compared to existing legacy solutions.
