Nas redes de dados das operadoras de telefonia celular é fundamental que o protocolo utilizado na comunicação entre terminais seja confiável e seguro e que possa prover o máximo de garantias a integridade dos dados. Os protocolos usualmente utilizados na comunidade científica fazem parte da pilha TCP/IP. O protocolo UDP não acrescenta confiabilidade à rede e apenas implementa a multiplexação. Por outro lado, o protocolo TCP tem a vantagem de ser um protocolo confiável possuindo conexões ponto-a-ponto. Na rede de telefonia celular, considera-se nas maioria das vezes o protocolo TCP e deseja-se que as vantagens de UDP existam no TCP. Desta forma, nessa dissertação optou-se pelo estudo dos protocolos SCTP e XTP por possuírem tais características em comum e acrescentar alguns diferenciais. Entre os recursos que mais de destacam no SCTP estão a transmissão de mensagens indivisíveis, múltiplos fluxos de mensagens por conexão, variação da confiabilidade das mensagens, entre outras. Por outro lado o XTP tem como características trabalhar em aplicações de alto desempenho, e por possuir similaridades com o TCP. A proposta deste trabalho de pesquisa é de prover um estudo empírico utilizando-se dos protocolos TCP, SCTP e XTP. O estudo caracteriza-se por considerar os recursos do SCTP e XTP, a fim de demonstrar em uma rede real interna de uma operadora de telefonia móvel o diferencial dos mesmos suportando protocolos de aplicação e simulando diversas condições de rede.

Der volle Inhalt der QuelleInteractive applications such as web browsing, audio/video conferencing, multi-player online gaming and financial trading applications do not benefit (much) from more bandwidth. Instead, they depend on low latency. Latency is a key determinant of user experience. An increasing concern for reducing latency is therefore currently being observed among the networking research community and industry. In this thesis, we quantify the proportion of potentially latency-sensitive traffic and its development over time. Next, we show that the flow start-up mechanism in the Internet is a major source of latency for a growing proportion of traffic, as network links get faster. The loss recovery mechanism in the transport protocol is another major source of latency. To improve the performance of latency-sensitive applications, we propose and evaluate several modifications in TCP. We also investigate the possibility of prioritization at the transport layer to improve the loss recovery. The idea is to trade reliability for timeliness. We particularly examine the applicability of PR-SCTP with a focus on event logging. In our evaluation, the performance of PR-SCTP is largely influenced by small messages. We analyze the inefficiency in detail and propose several solutions. We particularly implement and evaluate one solution that utilizes the Non-Renegable Selective Acknowledgments (NR-SACKs) mechanism, which has been proposed for standardization in the IETF. According to the results, PR-SCTP with NR-SCAKs significantly improves the application performance in terms of low latency as compared to SCTP and TCP.

Der volle Inhalt der QuelleThis thesis deals with a multipath solution for multi-interfaced mobile terminals that enables the use of parallel data paths to achieve higher throughput as well as transmission reliability in heterogeneous wireless networks. it proposes a transport-layer multipath solution called forward prediction scheduling (fps). fps alleviates the out-of-order data reception problem by estimating the delays incurred to data on each candidate path beforehand, and then scheduling the transmission of a data packet such that it is received in line with packets from other paths.preliminary performance evaluation of fps is carried out using ns-2's sctp-cmt model. this is then followed by fps implementation in linux kernel version of sctp (lksctp) and tests using a mobile device with heterogeneous set of wired and wireless network interfaces. the results prove the performance improvements brought by fps in face of high path delay ratios and dynamic wireless links.a cross-layer extension of fps mechanism is also proposed which contributes to accurate path delay calculations using layer-2 information in 802.11 wireless links.finally, a reliability-driven network coding multipath solution is proposed which enables a multi-interfaced host to transmit linearly encoded combinations of original data packets using its multiple paths. with the help of preliminary results, it is shown that the application of linear coding with fps mechanism significantly improves data transmission reliability as well as leads to less out-of-order reception problem

Der volle Inhalt der QuelleDenna uppsats behandlar säkerheten för morgondagens "peer-to-peer" (P2P) realtidskommunikation i heterogena nät. På grund av den adderade fördröjning som orsakas av inbandssignalering och dålig kompabilitet hos många transportprotokoll, så kan man fastställa att existerande säkerhetsprotokoll, såsom "(Datagram) Transport Layer Security" (TLS och DTLS), inte är lämpade för denna typ av kommunikation och att ett nytt säkerhetsprotokoll bör tas fram. "Transport Encapsulation Security Payload" (TESP) är ett sådant protokoll. TESP har inte bara fördelar såsom låg uppstartsfördröjning, utan har också stöd för många transportprotokoll, t.ex. "Transport Control Protocol" (TCP), "User Datagram Protocol" (UDP), "Stream Control Transmission Protocol" (SCTP) och "Datagram Congestion Control Protocol" (DCCP). Även en säkerhetsanalys av TESP har gjorts, där inga säkerhetsproblem har kunnat påvisas.

SCTP(Stream Control Transmission Protocol), a new fourth layer transport protocol, was proposed by the SIGTRAN Working Group of the IETF(Internet Engineering Task Force). The protocol is a connection-oriented and reliable transport service. It also supports multi-homing and multi-streaming mechanisms and can improve the transmission efficiency and enhance the security of traditional TCP. In this thesis we will focus on the congestion control for TCP (Transmission Control Protocol) (Tahoe, NewReno, SACK) and SCTP(SCTP, NewReno) and will compare the performance issue on delivery. We use the NS-2(Network Simulator-Version 2), a network simulation software, to simulate several scenarios of packet loss and congestion window size. The number of packets received, throughput and distribution of packet loss was simulated under two fourth layer transport protocol existing at the same time. The simulation results shows that the design of congestion control of SCTP is better than using TCP. The SCTP can not only reduce the probability of packet loss, but also improve the performance of delivery than TCP while face the suffering of multiple packet loss.
