This report sums up various available methods to find the best matching prefix (BMP) of a string especially for the purpose of IP address lookup in routers. The router decides what to do with an incoming packet according to the longest matching prefix in its routing table. This report does not contain any original methods nor results, it is intended purely as an overview. The method to be used ...

This work relates the areas of steganography, network protocols and security for practical data hiding in communication networks employing TCP/IP. Two approaches are proposed based on packet header manipulation and packet ordering within the IPSec framework. For the former the Internet protocol IPv4 header is analyzed to identify covert channels by exploiting redundancy and multiple interpretat...

lular radio networks is expected to become a critical part of future wireless operators’ service offerings [1]. However, because mobility is an essential characteristic of cellular networks, operators are faced with a confusing array of choices for how to architect such a network. The Internet Engineering Task Force’s (IETF’s) Mobile IP protocol [2] provides a standard solution for wide-area mo...

Over the recent years enormous changes in the telecommunication services, techniques, regulations and markets have taken place. However, even with many new exciting services the telephony service is still popular. This paper provides empirical traffic data and observations of telephony traffic patterns in mobile and IP telephony. They are presented and compared with old telephony patterns from ...

IP telephony, also called voice over Internet protocol (VoIP), is rapidly becoming a familiar term and technology that is implementing in the enterprise, education, government organizations and industry. Mobile IP telephony is the new generation of communications networks that makes possible the convergence of voice and data over wireless local area networks (WLANs). This technology combines da...

This study aimed to evaluate the efficacy of fructose-1,6-bis phosphate aldolase (SMALDO) DNA vaccination against Schistosoma mansoni infection using different routes of injection. The SMALDO has been cloned into the eukaryotic expression vector pcDNA3.1/V5-His TOPO-TA and was used in injecting Swiss albino mice intramuscularly (IM), subcutaneously (SC), or intraperitoneally (IP) (50 µg/mouse)....

Ioannidis, Ioannis. Ph.D., Purdue University, May, 2005. Algorithms and DataStructures for IP Lookups. Major Professor: Ananth Grama. The problem of optimizing access mechanisms for IP routing tables is an impor-tant and well studied one. Several techniques have been proposed for structuringand managing routing tables, with special emphasis on backbone, high-throughputrouting. T...

Smartphones connected to cellular networks are increasingly being used to access Internet-based services. Using data collected from smartphones running a popular location-based application, we examine IP address allocation in cellular data networks, with emphasis on understanding the applicability of IP-based geolocation techniques. Our dataset has GPS-based location data for approximately 29,0...

In this paper we present techniques for allowing Mobile IP to interwork with wide area cellular networks. As an example, we illustrate a network consisting of a GSM General Packet Radio Service (GPRS) air interface and a Mobile IP backbone network. The advantage of such a solution is that the backbone network may easily be used to support integrated wireless and wired data transfer, and the lev...
