Written Summary of Chapter Seven "Multimedia Networking" from the text
"Computer Networking: A Top-Down Approach"
The internet is becoming a place which increasingly meets the all the electronic needs of its users. With the advent of multimedia content and the ability of people, even in remote areas, to have access to broadband capabilities, any function of a telephone, television, or other single-use multimedia device is becoming intertwined with a computer's new multimedia ability. Chapter seven in the text defines and discusses the technologies that are, and are becoming, available to the public. This summary will include what these multimedia services are, a simple synopsis of how they work, and, finally, the future of the many applications that providers continue to implement.
The text broke the advances into three simple groupings -- streaming stored audio and video, one-to-many real-time audio and video, and real-time interactive audio and video (Krouse and Ross 598) -- which encompass all phases of the technology currently in use. Streaming stored audio and video can be further broken down into three component parts: stored media, which is prerecorded and stored on a dedicated server; streaming, audio or video that continues to load as the customer is watching it; continuous playout, which requires that the media be received instantly by the consumer or "users experience frustrating buffering delays"...
Another aspect of the security management area of a network management system is the development of policy-based auditing and alerts by role in the organization (Merilainen, Lemmetyinen, 2011). This is one of the areas of knowledge-enabled security management, specifically in the area of role-based access and advanced auditing and reporting. Fault management is also an area that no single suite of network management systems can completely meet per the ISO standards
Network Management and System Administration The aim of the paper is to establish the difference between a system administrator and a network administrator. The paper is thus divided into three sections. The first section deals with the basic definition and responsibilities of a system administrator; the second does the same for a network administrator and the third compares their responsibilities to clearly identify the differences between the two. System Administrator The maintenance of
). Such security should also preplan strategic responses to attacks associated with the network (Dawkins et al.). A book entitled "Surviving Security: How to Integrate People, Process, and Technology" explains that the rapid expansion networking and networking technologies necessitates greater security needs. The author asserts that parts of the network such as routers, switches and even network printers are vulnerable (Andress). The article further explains that the router or switch contained
competitive, fast-paced business world, a network failure can be disastrous. The pressure placed on network administrators to fix issues immediately is daunting; these important players need all the tools they can get to troubleshoot, prevent, and repair problems. Network administrators must remain vigilant and work constantly to monitor for interface or host failures, detect route flapping or intrusions, perform LAN segment switches or bandwidth adjustments, and monitoring overall performance
Network Design The process of gathering technical requirements for a network design project may differ from one organization to another, but the requirements themselves can be described using many of the concepts discussed in the lecture this week (i.e. Scalability, Availability, Network performance, Security, Manageability, and Affordability). Analyzing technical requirements for the customer is important in helping one best fulfill the customer's expectations. The various objectives that need to be fulfilled involve
