AbstrakStream Control Transmission Protocol (SCTP) merupakan protokol yang mirip dengan Transmission Control Protocol (TCP) dan User Datagram Protocol (UDP). SCTP merupakan protokol yang bersifat reliable dan connectionless. Protokol ini memiliki kemampuan multistreaming dan multihoming dalam melakukan transmisi data. Penelitian ini merupakan pemodelan terhadap SCTP menggunakan simulator OPNET yang dapat menjadi akselerasi bagi peneliti dalam bidang jaringan. SCTP pada simulator dibangun dengan melakukan modifikasi terhadap TCP. Pemodelan dimulai dengan membangun skenario jaringan dan menentukan bandwidth pada jalur yang akan dilewati oleh paket data.Modifikasi ukuran window dalam penelitian ini menggunakan nilai 1 MMS, 2 MMS hingga 10 MMS pada pengendali kemacetan. Tujuannya adalah untuk melihat pengaruh modifikasi ukuran window terhadap nilai packet loss, delay dan throughput. Hasil pengukuran memperlihatkan bahwa nilai throughput tertinggi terdapat pada Skenario Kedua sebagaimana diperlihatkan pada Tabel 6.4 dengan nilai throughput sebesar 433.566,0244 bit/s. Penggunaan ukuran window dalam pengendali kemacetan dimaksudkan untuk menghindari banjir data pada sisi endpoint yang dapat menyebabkan packet loss. Kata kunci—Pengendali kemacetan, throughput, delay, packet loss, ukuran window, multihoming, SCTP  Abstract Stream Control Transmission Protocol (SCTP) is a protocol that is similar to the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). SCTP is a protocol that is both reliable and connectionless. This protocol has the ability multistreaming and multihoming in the transmit data.This research is the modeling of the SCTP using OPNET simulator that can be accelerated for researchers in the field of networking. SCTP on the simulator was built to perform modifications to TCP. Modeling starts with building a network scenarios and determine the bandwidth on the path that will be passed by data packets.Modification of window size in this research using 1 MMS, 2 MMS up to 10 MMS on congestion control. The aim is to disclose the effect of modification of the window size to the value packet loss, delay and throughput. The measurement results show that the throughput rate is highest in the Second Scenario as shown in Table 6.4 with throughput value of 433.566,0244 bits/s. Using window size in congestion control is intended to prevent a flood of data on the endpoint that can lead to packet loss. Keywords—Congestion control, throughput, delay, packet loss, window size, multihoming, SCTP

Este artículo investiga los mecanismos de diferentes protocolos de transporte en transferencias sobre redes de alta capacidad y alto retardo, conocidas como Long Fat Networks (LFNs) para un envío eficiente de los datos. Transport Control Protocol (TCP) presenta limitaciones de rendimiento y flexibilidad. En la literatura se pueden encontrar diferentes propuestas de variantes del comportamiento de TCP, protocolos como Stream Control Transmission Protocol (STCP) o soluciones que proporcionan una comunicación confiable y mecanismos de control de congestión sobre User Datagram Protocol (UDP). En este artículo se presentan una serie de mecanismos de nivel de transporte para la optimización de transferencias de datos sobre redes LFN. Estos mecanismos ofrecen un rendimiento elevado utilizando todo el ancho de banda disponible del enlace mediante un proceso de cálculo del estado de la red y un control de congestión activo para la utilización de todo el bandwidth, a la vez que reactivo en caso de producirse pérdidas para evitar congestiones en la red. El objetivo es demostrar la eficiencia de dichos mecanismos, así como su adaptabilidad y aggressive friendliness respecto a otros protocolos de transporte mediante el despliegue de una serie de pruebas expuestas en este artículo.

Congestion Control Mechanism

The technologies of Wireless local networks and cellular network are very popular and more and more service under the integrated heterogeneous environment. Stream Control Transmission Protocol (SCTP) is considered as an ideal to support the communication between them by enabling a mobile client to freely switch the IP address in different networks. In this paper, we propose an extended analytical model for SCTP which consider the congestion window and scalable of congestion control mechanism. A great advantage of our model is that establishing a relationship between the throughput and congestion control mechanism. Furthermore, the analytical model provides a useful tool to improve congestion control mechanism of SCTP.

Use Of The Internet

The use of the internet has increased significantly with the continued increase in wireless communication devices. Recently, there is a large number of research contribution focused on Stream Control Transmission Protocol (SCTP). Multi-homing is an important feature of SCTP which improves the communication performance by usage of multiple paths during association establishment, and it can bring significant improvements of throughput. In this thesis we evaluate the performance of SCTP and TCP traffic in the WLANs and we investigate the SCTP multi-homing to improve the communication performance in WLANs. We conducted some experiments to evaluate the performance of SCTP multi-homed host under various channel bit rates and mobility speeds. The results indicate that when the intensity of background traffic increases the SCTP multi-homed host with higher channel bit rate has better performance. In addition, the SCTP multi-homed host with using lower mobility speed has higher performance (throughput, delay and packet loss).

Congestion is an un-avoiding issue of networking, and many attempts and mechanisms have been devised to avoid and control congestion in diverse ways. Random Early Discard (RED) is one of such type of algorithm that applies the techniques of Active Queue Management (AQM) to prevent and control congestion and to provide a range of Internet performance facilities. In this chapter, performance of RED algorithm has been measured from different point of views. RED works with Transmission Control Protocol (TCP), and since TCP has several variants, the authors investigated which versions of TCP behave well with RED in terms of few network parameters. Also, performance of RED has been compared with its counterpart Drop Tail algorithm. These statistics are immensely necessary to select the best protocol for Internet performance optimization.

This chapter will introduce three new IETF transport layer protocols in support of multimedia data transmission and discuss their usage. First, the stream control transmission protocol (SCTP) will be described; this protocol was originally designed for telephony signaling across the Internet, but it is in fact broadly applicable. Second, UDP-Lite (an even simpler UDP) will be explained; this is an example of a small protocol change that opened a large can of worms. The chapter concludes with an overview of the datagram congestion control protocol (DCCP), a newly devised IETF protocol for the transmission of unreliable (typically real-time multimedia) data streams.

Protocol Analyzer

This study aims to analyze Performance of TCP, UDP and SCTP Protocol on Multimedia Traffic. The TCP (Transmission Control Protocol) protocol, UDP (User Datagram Protocol) and SCTP (Stream Control Transmission Protocol) reside on the same layer in the OSI-Layer at the Transport layer that controls the flow of data, data packets and so on. This research uses windows operating system and Softperfect Network Protocol Analyzer software. Where network analysis software has a complete feature such as can filter almost all the protocol on the OSI-Layer, has a report of easy to read results and so forth. From the test results conducted for three days by analyzing the online and offline way obtained SCTP protocol results both for Multimedia activities but can not be used simultaneously with other activities (such as video conversations). for everyday activities should use TCP and UDP protocol because it tends to be stable.Keyword : TCP, UDP, SCTP
