Storage (Lecture 17)

Scribed by Gregory Chanan Joy Jiang and Claudio DeSanti, The role of FCoE in I/O consolidation, Proceedings of the 2008 International Conference on Advanced Infocomm Technology Summary: This paper describes the trend towards data center I/O consolidation. Conventionally, there are different networks running in parallel, optimized for different uses: Ethernet for LAN, Fibre Channel for [...]

Storage (Lecture 17)

Scribed by Matt Fichman The Role of FCOE in I/O Construction Summary Recently there has been a trend in data center networks toward the consolidation of multiple traffic types over a unified data network.  Currently, several different high-speed networking technologies exist.  Ethernet is used primarily for the LAN.  Fibre Channel is used for the SAN, [...]

Storage (Lecture 17)

Scribed by Haruki Oh The Role of FCoE in I/O Consolidation Summary: This paper explores the possibility and benefit of Fibre Channel over Ethernet protocol to consolidate multiple traffic types in datacenters. The greatest benefit of consolidating multiple traffic type is the significant reduction in the number of wires and switches, and power consumption. Internal [...]

Storage (Lecture 17)

Joy Jiang and Claudio DeSanti, The role of FCoE in I/O consolidation, Proceedings of the 2008 International Conference on Advanced Infocomm Technology Summary of Paper The paper describes the rational for adopting FCoE protocol as a way to I/O consolidation at the datacenter level. Specifically, FCoE describes running Fibre Channel over 10GB Ethernet, and thus [...]

Network Security (Lecture 16)

Network Security (Lecture 16) Scribed by Frank Nothaft Abraham Yaar et al., SIFF: A Stateless Internet Flow Filter to Mitigate DDoS Flooding Attacks, IEEE Security and Privacy Symposium 2004 Summary: This paper discusses a filter that should mitigate DDoS attacks by allowing a packet flow recipient to prevent disruptive flows from impacting them. SIFF realizes [...]

UNH-IOL Fibre Channel Tutorial and Joy Jiang and Claudio DeSanti, The role of FCoE in I/O consolidation, Proceedings of the 2008 International Conference on Advanced Infocomm Technology Scribed by Nishchay Sinha Summary: This lecture was our introduction to fiber channel protocol used in  storage area network.The tutorial tersely discussed an idiot’s introduction to  FC which [...]

Network Security (Lecture 16)

A. Yaar, A. Perrig, D. Song, SIFF: A Stateless Internet Flow Filter to Mitigate DDoS Flooding Attacks, IEEE Security and Privacy Symposium, 2004 Summary of Paper SIFF provides network hosts with a defense against DDoS flooding attacks by providing them with a means of signaling to the upstream routers to drop a particular traffic flow. [...]

Lecture 16:Security

A. Yaar, A. Perrig, D. Song, SIFF: A Stateless Internet Flow Filter to Mitigate DDoS Flooding Attacks, IEEE Security and Privacy Symposium, 2004 Scribed by:Nishchay Sinha Summary: The paper focuses on paradigms of  DDOS  attacks and one of its solutions.By allowing the server to let only those traffic reach to it,the SIFF is able to [...]

Network Security (Lecture 15)

V. Paxson, Bro: A System for Detecting Network Intruders in Real-Time, In the ACM Workshop on Hot Topics in Networks (HotNets), Dec 1999/Nov 2005 Summary of Paper A standalone system for network intrusion detection Bro is described. Bro passively monitors a network link and is characterized by high speed monitoring, real-time notification, clear separation between [...]

Network Security (Lecture 15)

Scribed by Kyle Horimoto Handley and V. Paxson, Network Intrusion Detection: Evasion, Traffic Normalization, and End-to-End Protocol Semantics, USENIX 2001 Summary Network intrusion detection systems (NIDS) are often used to increase network security by preventing known attacks from entering the network. However, sometimes data sent sent through NIDS cannot be unambiguously deciphered as valid traffic [...]
