DDOS Detection and Denial Using Third Party Application in SDN
International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS-2017) DDOS Detection and Denial using Third Party Application in SDN Roshni Mary Thomas Divya James Dept. of Information Technology Dept. of Information Technology Rajagiri School of Engineering & Technology Rajagiri School of Engineering & Technology Ernakulam, India Ernakulam, India [email protected] [email protected] Abstract— Software Defined Networking(SDN) is a developing introduced i.e, Software Defined Networking (SDN). Software area where network managers can manage the network behavior Defined Networking (SDN) is a developing area where it programmatically such as modify, control etc. Using this feature extract the limitations of traditional network which make we can empower, facilitate or e network related security networking more uncomplicated. In SDN we can develop or applications due to the its capacity to reprogram the data plane change the network functions or behavior program. To make at any time. DoS/DDoS attacks are attempt to make controller the decision where the traffic needs to send with the updated functions such as online services or web applications unavailable to clients by exhausting computing or memory resources of feature SDN decouple the network planes into two. servers using multiple attackers. A DDoS attacker could produce 1. Control Plane enormous flooding traffic in a short time to a server so that the 2. Data Plane services provided by the server get degraded. This will lose of In control plane we can add update or add new features customer support, brand trust etc. to improve the network programmatically also we can change To detect this DDoS attack we use a traffic monitoring method the traffic according to our decision and in updated traffic are iftop in the server as third party application and check the traffic applied in data plane. -
Data Transfer Node (DTN) Tests on the GÉANT Testbeds Service (GTS)
09-12-2020 Data Transfer Node (DTN) Tests on the GÉANT Testbeds Service (GTS) Grant Agreement No.: 856726 Work Package WP6 Task Item: Task 2 Document ID: GN4-3-20-265f683 Authors: Iacovos Ioannou (CYNET), Damir Regvart (CARNET), Joseph Hill (UvA/SURF), Maria Isabel Gandia (CSUC/RedIRIS), Ivana Golub (PSNC), Tim Chown (Jisc), Susanne Naegele Jackson (FAU/DFN) © GÉANT Association on behalf of the GN4-3 project. The research leading to these results has received funding from the European Union’s Horizon 2020 research and innovation programme under Grant Agreement No. 856726 (GN4-3). Abstract Many research projects need to transfer large amounts of data and use specialised Data Transfer Nodes (DTNs) to optimise the efficiency of these transfers. In order to help NRENs to better support user communities who seek to move large volumes of data across their network, a DTN Focus Group was set up in the Network Technologies and Services Development work package (WP6) of the GN4-3 project, which has performed several activities around DTN deployment, the results of which are summarised in this document.

Lab Manual SECTION 4 NETWORK PROGRAMMING AND ADMINISTRATION EXERCISES Structure Page Nos. 4.0 Introduction 48 4.1 Objectives 48 4.2 Lab Sessions 49 4.3 List of Unix Commands 52 4.4 List of TCP/IP Ports 54 3.5 Summary 58 3.6 Further Readings 58 4.0 INTRODUCTION In the earlier sections, you studied the Unix, Linux and C language basics. This section contains more practical information to help you know best about Socket programming, it contains different lab exercises based on Unix and C language. We hope these exercises will provide you practice for socket programming. Towards the end of this section, we have given the list of Unix commands frequently required by the Unix users, further we have given a list of port numbers to indicate the TCP/IP services which will be helpful to you during socket programming. To successfully complete this section, the learner should have the following knowledge and skills prior to starting the section. S/he must have: • Studied the corresponding course material of BCS-052 and completed the assignments. • Proficiency to work with Unix and Linux and C interface. • Knowledge of networking concepts, including network operating system, client- server relationship, and local area network (LAN). Also, to successfully complete this section, the learner should adhere to the following: • Before attending the lab session, the learner must already have written steps/algorithms in his/her lab record. This activity should be treated as home- work that is to be done before attending the lab session. • The learner must have already thoroughly studied the corresponding units of the course material (BCS-052) before attempting to write steps/algorithms for the problems given in a particular lab session.
