NFV Decouples the Network Functions Such As NAT, Firewall, DPI, IPS/IDS, WAAS, SBC, RR Etc
Virtualizing Enterprise Network Functions • BRKCRS-3447 Matt Falkner, Distinguished Engineer, Technical Marketing Agenda BRKCRS-3447 • Introduction & Motivation • Deployment Models and Characteristics • The Building Blocks of Virtualization (today) • Virtualization Trade-offs and Research Topics • Conclusion Abstract Network Function Virtualization (NfV) is gaining increasing traction in the industry based on the promise of reducing both CAPEX and OPEX using COTS hardware. This session introduces the use-cases for virtualizing Enterprise network architectures, such as virtualizing branch routers, LISP nodes, IWAN deployments, or enabling enterprise hybrid cloud deployments. The sessions also discusses the technology of Virtualization from both a system architecture as well as a network architecture perspective. Particular focus is given on understanding the impact of running routing functions on top of hypervisors, as well as the placement and chaining of network functions. Performance of virtualized functions is also discussed. BRKCRS-3447 © 2016 Cisco and/or its affiliates. All rights reserved.

Freelab: a Free Experimentation Platform
FreeLab: A Free Experimentation Platform Matteo Varvello|; Diego Perino? |AT&T Labs – Research, ?Telefónica Research ABSTRACT In this work, we set out to build a free experimentation As researchers, we are aware of how hard it is to obtain access platform which can also be reliable and up-to-date. In classic to vantage points in the Internet. Experimentation platforms experimentation platforms applications run directly at vantage are useful tools, but they are also: 1) paid, either via a mem- points; we revert this rationale by proposing to use vantage bership fee or by resource sharing, 2) unreliable, nodes come points as traffic relays while running the application at theex- and go, 3) outdated, often still run on their original hardware perimenter’s machine(s). By leveraging free Internet relays as and OS. While one could build yet-another platform with vantage points, we can make such experimentation platform up-to-date and reliable hardware and software, it is hard to free. The drawback of this approach is the introduction of imagine one which is free. This is the goal of this paper: we extra errors (path inflation, header manipulation, bandwidth set out to build FreeLab, a free experimentation platform shrinkage) which need to be carefully corrected. which also aims to be reliable and up-to-date. The key idea This paper presents FreeLab, a free experimentation plat- behind FreeLab is that experiments run directly at its user form built atop of thousand of free HTTP(S) and SOCKS(5) machines, while traffic is relayed by free vantage points inthe Internet proxies [38]—to enable experiments based on TCP, Internet (web and SOCKS proxies, and DNS resolvers). -

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. -
