OpenFlow: enabling innovation in campus networks
This whitepaper proposes OpenFlow: a way for researchers to run experimental protocols in the networks they use every day. OpenFlow is based on an Ethernet switch, with an internal flow-table, and a

TLDR
An architecture for Burst Switching Systems designed to switch data among WDM links, treating each link as a shared resource rather than just a collection of independent channels is presented.
Overcoming the Internet impasse through virtualization
The Internet architecture has proven its worth by the vast array of applications it now supports and the wide variety of network technologies over which it currently runs. Most current Internet
Scalable high speed IP routing lookups
TLDR
This paper describes a new algorithm for best matching prefix using binary search on hash tables organized by prefix lengths that scales very well as address and routing table sizes increase and introduces Mutating Binary Search and other optimizations that considerably reduce the average number of hashes to less than 2.
Algorithms to accelerate multiple regular expressions matching for deep packet inspection
TLDR
This paper introduces a new representation for regular expressions, called the Delayed Input DFA (D2FA), which substantially reduces space equirements as compared to a DFA, and describes an efficient architecture that can perform deep packet inspection at multi-gigabit rates.
Fast hash table lookup using extended bloom filter: an aid to network processing
TLDR
This work presents a novel hash table data structure and lookup algorithm which improves the performance over a naive hash table by reducing the number of memory accesses needed for the most time-consuming lookups, which allows designers to achieve higher lookup performance for a given memory bandwidth.
ClassBench: A Packet Classification Benchmark
TLDR
This work presents ClassBench, a suite of tools for benchmarking packet classification algorithms and devices and seeks to eliminate the significant access barriers to realistic test vectors for researchers and initiate a broader discussion to guide the refinement of the tools and codification of a formal benchmarking methodology.
Curing regular expressions matching algorithms from insomnia, amnesia, and acalculia
TLDR
It is argued that the traditional DFA based NIDS has three main limitations: first they fail to exploit the fact that normal data streams rarely match any virus signature, and second, DFAs are extremely inefficient in following multiple partially matching signatures and explodes in size, and third, finite automaton are incapable of efficiently keeping track of counts.
Efficient Mapping of Virtual Networks onto a Shared Substrate
TLDR
This paper develops a method for mapping a virtual network onto a substrate network in a cost-efficient way, while allocating sufficient capacity to virtual network links to ensure that the virtual network can handle any traffic pattern allowed by a general set of traffic constraints.
