High quality multimedia streaming over the Internet has proliferated in modern society due to the ever-increasing ties amongst people and businesses, thereby occupying the majority of all exchanged data traffic. The Internet is the primary multimedia exchange medium that is being used beyond its intended design. Using Hypertext Transfer Protocol/Transmission Control Protocol (HTTP/TCP), multimedia can be delivered to virtually all devices connected to the Internet. HTTP-based streaming suffers from the increasing overhead generated as the stream length, quality, and non-deterministic path conditions vary. In this paper, a novel cross-layer signalling reduction scheme is proposed to alleviate resource consumption in networks exchanging multimedia. The proposed scheme is a steganographic-based protocol translator that encodes information within multimedia payloads prior to packet flight to reduce the size of exchanged data. The encoded data is used by node pairs to replace bulky protocols, such as TCP, with lightweight protocols, such as User Datagram Protocol (UDP). In addition to the protocol translator, a routing scheme is given to be used in place of the inflated networking protocols to further reduce the header footprint. A utility function is developed to find the optimal overhead savings where simulations are conducted to verify the designs. Using virtual machines, the proposed translator is implemented where a multimedia file is exchanged and subject to encoding. The simulations and implementation show that the proposed methodologies will decrease the amount of signalling needed while increasing the overall network capacity. Furthermore, the proposed methods are capable of successfully extending existing signalling reduction methods.

基于隐写术的多媒体流头大小减少技术

由于人们与企业之间日益紧密的联系,互联网上高质量的多媒体流在现代社会中激增了,从而占据了所有交换数据流量的大部分。互联网是主要的多媒体交换媒体,其使用超出了其预期的设计。使用超文本传输​​协议/传输控制协议(HTTP / TCP),多媒体可以传递到几乎所有连接到Internet的设备上。随着流长度,质量和不确定路径条件的变化,基于HTTP的流将遭受越来越大的开销。本文提出了一种新颖的跨层信令减少方案,以减少多媒体交换网络中的资源消耗。所提出的方案是基于隐写术的协议翻译器,其在分组飞行之前对多媒体有效载荷内的信息进行编码以减小交换数据的大小。节点对使用已编码的数据,以轻量级协议(例如用户数据报协议(UDP))替换大容量协议(例如TCP)。除了协议转换器之外,还提供了一种路由方案来代替膨胀的网络协议,以进一步减少报头占用量。开发了一种实用程序功能,可以找到最佳的开销节省,在其中进行仿真以验证设计。使用虚拟机,可以实现所建议的翻译器,其中交换多媒体文件并进行编码。仿真和实现表明,所提出的方法将减少所需的信令数量,同时增加整体网络容量。此外,所提出的方法能够成功地扩展现有的信令减少方法。
