Service identification in TCP/IP : well-known versus random port numbers
… at the most fundamental level is only to demultiplex flows of traffic. Several unintended uses of the port number evolved from associating services with a list of well-known port numbers. This thesis documents those unintended consequences in an effort to describe the port number's influence on …

TCP/IP stack fingerprinting for patch detection in a distributed Windows environment
… of finding patterns for missing patches by using TCP/IP Stack Fingerprinting. Malformed TCP packets are sent to the target system and the TCP and IP headers of the response from it are analyzed to find out specific patterns for a missing patch.;Windows based systems are the primary target since …

Adaptive Protocols to Improve TCP/IP Performance in an LMDS Network using a Broadband Channel Sounder
… broadband sounder hold the promise of improving TCP/IP performance by trigging configuration changes in an adaptive data link layer protocol. We present an adaptive data link layer protocol that can use different levels of forward error correction (FEC) codes and link layer automatic …

Identifying and analyzing sources of overhead in the TCP/IP communication protocol over a local area network
… area network for two transport layer protocols: TCP and UDP. The sensitivity of user-level performance to the choice of different speed hosts, host loads, and application program interfaces are studied. Our measurements serve as a guide in designing performance critical applications. Moreover, we …

Simulation Study of an ADSL Network Architecture: TCP/IP Performance Characterization and Improvements using ACK Regulation and Scheduling Mechanisms
… research aims at characterizing and analyzing TCP/IP performance in presence of a new protocol stack (TCP/IP over PPP and ATM) being promoted for one of the ADSL network architectures. Using extensive simulations, we verify the adverse effects of asymmetric links on the performance of TCP and …

Socketless TCP : a connection identification philosophy for end to end mobility
… of this vision is how to support this model in TCP/IP networks. We argue that the TCP/IP socket pair connection identification model restricts this granularity and flexibility of mobility. We present Socketless TCP (SL-TCP), an architectural concept based on reconsidering the socket pair for …

Visual Correlation of Network Traffic and Host Processes for Computer Security
… processes that cause them. The strictly layered TCP/IP networking model that underlies all widely used, general-purpose operating systems makes it impossible to trace a packet seen on the network back to the processes that are responsible for generating and receiving it. The TCP/IP model …

Accountable logging and its applications to intrusion detection
… systems brings us the chance to achieve multiple degrees of accountability, which means we are able to acknowledge the system's behaviors at different levels of accountability. In this dissertation, a multi-resolution flow-net is proposed for achieving multi-layer accountability. Moreover, …

Software Switching for High Throughput Data Acquisition Networks
… systems, is particularly demanding for commodity TCP/IP and Ethernet technologies. The problem arising from this pattern is widely known in the literature as incast and can be observed as TCP throughput collapse. It is a result of overloading the switch buffers, when a specific node in a network …

Interactions between TCP and link layer protocols on mobile satellite links
… networks, satellite-based systems must support TCP/IP traffic. However, TCP performs poorly on land-mobile satellite channels because of large propagation delays and frequent correlated packet loss. The use of a link layer ARQ protocol can improve TCP performance by insulating TCP from data. …

Advanced Network Inference Techniques Based on Network Protocol Stack Information Leaks
… channels, where information flow occurs in the TCP/IP network stack implementations of operating systems. I will describe three new types of idle scans: a SYN backlog idle scan, a RST rate-limit idle scan, and a hybrid idle scan. Idle scans are special types of side channels that are designed to …
