Penggunaan akses internet di dunia semakin berkembang, dan selaras dengan perkembangan teknologi jaringan komputer yang semakin kompleks. Oleh karena itu, keamanan data pada sebuah komputer menjadi salah satu bagian yang sangat penting dalam sebuah jaringan. Dan SDN merupakan sebuah solusi untuk menyediakan kebutuhan jaringan komputer saat ini. Software Defined Network (SDN) merupakan pendekatan pada teknologi jaringan yang melakukan penyederhanaan terhadap kontrol dan manajemen jaringan. Pada jaringan ini nantinya akan menggunakan protokol openflow, yang prinsip utamanya memisahkan fungsi control plane dan data plane pada perangkat. Kontrol jaringan pada sebuah controller bersifat programmable, jadi dengan adanya SDN maka jaringan akan mudah diatur dan lebih fleksibel. Implementasi dan analisis firewall ini menggunakan emulator mininet untuk membuat topologi jaringan yang sederhana. Dalam pengujian firewall menggunakan bahasa XML untuk implementasi aliran data, lalu menggunakan aplikasi postman sebagai alat untuk menambahkan flow table baru pada switch, dan controller yang digunakan adalah opendaylight.

Software Defined Network (SDN) is a new network architecture which separates the data plane from the control plane. The SDN controller implements the control plane and switches implement the data plane. Many papers discuss about DDoS attacks on primary servers present in SDN and how they can be mitigated with the help of controller. In our paper we show how DDoS attack can be instigated on the SDN controller by manipulating the flow table entries of switches, such that they send continuous requests to the controller and exhaust its resources. This is a new, but one of the possible way in which a DDoS attack can be performed on controller. We show the vulnerability of SDN for this kind of attack. We further propose a solution for mitigating it, by running a DDoS Detection module which uses variation of flow entry request traffic from all switches in the network to identify compromised switches and blocks them completely.

Network Switch

Standard core of communications’ networks is represent by active elements, which carries out the processing of transmitted data units. Based on the results of the processing the data are transmitted from sender to recipient. The hardest challenge of the active elements present to determine what the data processing unit and what time of the system to match the processing priority assigned to individual data units. Based on the analysis of the architecture and function of active network components and algorithms, artificial neural networks can be assumed to be effectively useable to manage network elements. This article focuses on the design and use of the selected type of artificial neural network (Hopfield neural network) for the optimal management of network switch.

Ethernet Switch

The SDN controller is interfaced with the hardware of the network (i.e., with switches and routers) using OpenFlow. Basically, OpenFlow is an open interface used for configuring the forwarding tables of network switch according to the desired path derived by the SDN controller. OpenFlow enables more innovation in controller platforms and applications, and describes a solution for each frame or packet flow. OpenFlow is based on an ethernet switch with an internal flow-table and a standardized interface to add and remove flow entries of forwarding table of the system. The control mechanism from each one of the switch and router up to SDN controller are encrypted with the transport layer security (TLS) and secure socket layer (SSL) OpenFlow protocols to provide the additional security inside the network.

This work presents a network processing unit based on specialized computational cores that is used for packet processing in network devices (e.g. in network switches). Nowadays stateful data-plane algorithms are developing in software-defined networks. The idea of stateful data-plane algorithms is to move a part of control information from control plane to data plane. But these algorithms require hardware support because they need resources for state handling. This work presents the network processing unit architecture modifications that allow to use stateful data-plane algorithms that require state synchronization between the NPU processing pipelines.
