Recommended: Implementation of multicast in network routing protocols

Multicast Tree Algorithm in ATM Network Environment

Overview:
The use of optical fiber has tremendously increased network bandwidth. The data used in video-on-demand (VOD), distant learning, distant diagnosis, video conferences, and many other applications have popped up one after another in recent years. They all require that the same data be sent to multiple recipients. This operation is called multicasting.

Introduction:
Asynchronous Transfer Mode (ATM) is the mostly implemented in high speed networks. ATM is the transmission system for CCITT's next-generation ISDN, Broadband ISDN (B-ISDN). B-ISDN is designed to provide subscriber communication services over a wide range of bit rates from megabits to several gigabits.
The primary goal in routing multicast connections is to make efficient use of the network resources and to establish fast connections for data transmission. The network is often defined by a graph G(V,E) . Multicast routing protocols are been used in practical systems such as multicast backbone(M bone).M bone chooses the shortest path to each destination using the IP routing mechanism.Multicast routing in ATM Switch performs two basic functions such as switch and queuing.

PROBLEM DESCRIPTION:
ATM NETWORK
ATM Network can be modeled by an connected graph G(V,E).The performance of the multicast routing in a system can be measured by following criteria.
Cost of establishing connection Ce: Total number of VPs connected from source to all destinations. The VC connection between the source and destination is either direct VP or the concatenation of multiple VPs. Ce is the cost of setting up connection for subsequent multicasting
Cost of bandwidth (Cb)and switching(Cs): Bandwidth cost ...

MBS synchronization. In other technique R-MP-MBS PER is improved and MBS synchronization is not
Possible in this technique this is the only disadvantage in this technique. Both these techniques attractively gives solution for next-generation relay based wireless network. By this multicasting broadband services the data can be transferred in the emergency situations this is an advanced version for transmitting the data at any emergency situations to longer distance.

    With an IPv4 network, all the work consisting of network renumbering and assigning of new address schemes would had been done manually. Another useful feature of IPv6 is the multi-homing technique. It allows simultaneous connections which are established to two ISPs. Compared to IPv4, IPv6 has a much simpler packet header structure, which is designed to minimize the time and efforts that go in to header processing. IPv6 offers better end-to-end connectivity than its predecessor IPv4. The most exciting applications to emerge in todays world is peer-to-peer applications such as multi-player online games, video-conferencing (streaming), file sharing and

  • Essay On Gated Channels

    1119 Words  | 3 Pages

    5) Gated channels are used to facilitate the movement of molecules from one side of a membrane to another and are necessary for facilitated diffusion. A gated channel can be open, closed, or in an intermediate state, and are controlled by change in membrane voltage, and differs from active by not requiring additional ATP for movement like active transport. Gated channels are exactly what they sound like, a channel that is controlled by a gate or regulator that will allow the movement of specific molecules in and out of cells. Gated channel facilitated diffusion relies on channel proteins, that form hydrophilic channels which allow the movement water and piggybacking ions through a membrane. An example of a gated channel is the importation of

  • Ethernet And Atm: Which Will Prevail?

    968 Words  | 2 Pages

    ATM is geared toward high speed voice and video transmission, much like a telephone network. It uses a cell-switching and multiplexing technology. The data (this refers to data, voice and video) is transferred between two points on a dedicated circuit in 53 byte cells. Each cell is the exact same size, no matter what data is being sent. The cells consist of 5 bits of header information and 48 bits of actual data. Using a smaller, consistent cell size means there's less delay between when each cell processes at the other end. Using dedicated circuits via virtual circuits ensures there is no interruption in the data transfer. This is extremely important to voice and video transmissions, because they are highly intolerant to data delays. This improves the Quality of Service (QoS) and speed of transfer, which can be between 25 Mbps to 622 Mbps.

    In recent years, network coding [1], [2] has been considered as an auspicious information network paradigm for augmenting the throughput of multiple unicast networks [5]. The pioneering researches of network coding were undertaken by R. Ahlswede, N. Cai, S.-Y.R. Li and R.W. Yeung. Their discovery, which was first introduced in [1][2], are considered to be the crucial breakthrough in modern information theory and the time of its appearance, is recognized as the beginning of a new theory-Network Coding theory. In these elegant, succinct articles, within the purview of rigorous mathematics, the glimmering of an optimal network protocol for multiple unicast network was introduced in which the key idea is considering digital information as wave [riis].

    When learning code you become familiar with one language at a time, whether it be Java, Visual Basic, etc. Code converters change one code language to another language. For example, Sharp Develop is a free code converter that converts C# language into Visual Basic. There are sets of rules you must know before using a code converter. Before converting code, be sure that the code can be run and compiled. For C# to VB.Net you may have to do some editing after you convert them. For other language pairs, you have to make sure that the converter supports the target language you seek.

    Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.

    Since nodes themselves are not relied upon for communication, the failure of a single node is not problematic for the rest of the network. For a major issue to occur, there must be a problem with the bus itself. Despite its simplicity and reliability, the bus network does have several limitations. The cable length of the bus is limited due to data loss. Also, a bus network may have performance issues if the nodes are located at scattered points and do not lie near a common line....
