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 standardized interface to add and remove flow entries. Our goal is to encourage networking vendors

controller for processing table-missed flows. We propose a simple flow entry management scheme for reducing the controller overhead by increasing the flow entry matching ratio. By using an LRU caching algorithm, a switch can keep the flow entries in a flow table as many as possible, and then the flow entry

The flow switching capability is attractive in software defined networking (SDN). Today, variety of flow switches are rolled out utilizing existing switching plat-forms, however, the number of flow entries is effective-

We introduce program shepherding, a method for monitoring control flow transfers during program execution to enforce a security policy. Program shepherding provides three techniques as building blocks for security policies. First, shepherding can restrict execution privileges on the basis of code

The precise research problem is; how to prevent accountants and managers from conducting financial fraud – importance of having an internal control system? The thesis has been commissioned by HAAGA-HELIA University of Applied Sciences, which expects to receive valuable research concerning ethics in financial accounting. To approach the problem, first some theory behind fraud, risk management and internal control will be looked at. The two of the most famous financial fraud cases, Enron and the Lehman Brothers, will be shortly presented. These, and an overview of

. Better performing partnerships are more likely to raise follow-on funds and larger funds. This relationship is concave so that top performing partnerships grow proportionally less than average performing partnerships. At the industry level, market entry and fund performance is cyclical; however

Argentina resembles Continental Europe with smaller flows and less impressive post-entry growth of successful firms.
