Resilient Interdomain Traffic Exchange: BGP Security and DDos Mitigation

December 17, 2019
Author(s)
Kotikalapudi Sriram, Douglas C. Montgomery
In recent years, numerous routing control plane anomalies, such as Border Gateway Protocol (BGP) prefix hijacking and route leaks, have resulted in denial-of-service (DoS), unwanted data traffic detours, and performance degradation. Large-scale distributed

vPROM: vSwitch Enhanced Programmable Measurement in SDN

October 10, 2017
Author(s)
An Wang, Yang Guo, Songqing Chen, Fang Hao, T.V. Lakshman, Douglas C. Montgomery, Kotikalapudi Sriram
Network programmability is a salient feature of Software Defined Networking (SDN), which allows users to program network applications with the perception that the underlying network is a single device. While still at an early stage of development, SDN

A Comparative Analysis of BGP Anomaly Detection and Robustness Algorithms

January 28, 2009
Author(s)
Kotikalapudi Sriram, Oliver Borchert, Patrick Gleichmann, Douglas C. Montgomery
We present an evaluation methodology for comparison of existing and proposed new algorithms for Border Gateway Protocol (BGP) anomaly detection and robustness. A variety of algorithms and alert tools have been proposed and/or prototyped recently. They

Architectural Considerations for Mapping Distribution Protocols

August 1, 2008
Author(s)
Kotikalapudi Sriram, Young-Tak Kim, Douglas C. Montgomery
In this paper, we present a discussion of some architectural ideas pertaining to the mapping distribution protocol. The efficiency of this protocol in terms of response time and the volume of traffic load it generates are important considerations. We

Border Gateway Protocol Security

July 17, 2007
Author(s)
D. Richard Kuhn, Kotikalapudi Sriram, Douglas Montgomery
This document introduces the Border Gateway Protocol (BGP), explains its importance to the internet, and provides a set of best practices that can help in protecting BGP. Best practices described here are intended to be implementable on nearly all

Study of BGP Peering Session Attacks and Their Impacts on Routing Performance

October 1, 2006
Author(s)
Kotikalapudi Sriram, Douglas C. Montgomery, Oliver Borchert, Okhee Kim, David R. Kuhn
We present a detailed study of the potential impact of BGP peering session attacks and the resulting exploitation of Route Flap Damping (RFD) that cause network-wide routing disruptions. We consider canonical grid as well as down-sampled realistic

Autonomous System (AS) Isolation under Randomized BGP Session Attacks with RFD Exploitation

April 1, 2006
Author(s)
Kotikalapudi Sriram, Douglas Montgomery, Oliver Borchert, Okhee Kim, D. Richard Kuhn
BGP peering session attacks are known to drive routes into route flap damping (RFD) suppression states and thus cause isolations between autonomous systems (ASes) and destinations. We present a detailed study of the impact of BGP peering session attacks

Protection Switching for Optical Bursts Using Segmentation and Deflection Routing

October 1, 2005
Author(s)
David W. Griffith, Kotikalapudi Sriram, Nada T. Golmie
Burst segmentation in OBS networks can significantly reduce the amount of data that is lost due to contention events by dropping or deflecting only the portion of a burst that overlaps another contending burst. In this letter, we demonstrate how

Resource Planning and Bandwidth Allocation in Hybrid Fiber-Coax Residential Networks

October 1, 2005
Author(s)
David W. Griffith, Kotikalapudi Sriram, L Krivulina, Nada T. Golmie
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Wireless Enhancements for Storage Area Networks

October 1, 2005
Author(s)
David W. Griffith, Kotikalapudi Sriram, J Gao, Nada T. Golmie
We propose the creation of a wireless storage area network (SAN) and analyze its benefits. The proposed wireless SAN (WSAN) consists of a SAN switch that is connected to multiple wireless access points (APs) that communicate with the storage devices. This

A Review of Current Research Work on BGP Security
