  • Essay On Computer Network Topology

    904 Words  | 4 Pages

    Computer network topology is the way different parts of a network (like hubs, connections, peripherals, and so on) are arranged. System topologies characterize the format, virtual shape or structure of network, physically as well as logically. The path in which distinctive frameworks and hubs are associated and communicate with one another is dictated by topology of the network. Topology can be physical or logical. Physical Topology is the physical format of hubs, workstations and cables in the

    half-duplex systems, if more than one emits a transmission at the same time, a collision will occurs and messages will be lost. The messages sent by nodes are corrupted. The receiving nodes receive random data. In half-duplex networks, the node transmitting must make sure that the network is quiet prior to transmitting, and in addition there is usually some mechanism for transmitting nodes to detect overlapping transmissions. 10BASE5 coaxial cable is the transmission technology used in the classic Ethernet

If an “alive” message is not received, (e.g. the phone is off-network, the user is on a voice call, the server is down), then the phone begins buffering location data until the next “alive” message is

    Figure1 a network I configured in Cisco Packet Tracer. In RIP a hop is counted as a metric from router to router. So if the source in this example is “PC-Jemine1” with the destination being “PC-Jemine2” RIP would use a hop count of 5. This would be: ➢ Source =PC-Jemine1 ➢ Router 0 to Router 1 = Hop Count 1 ➢ Router 1 to Router 3 = Hop Count 2 ➢ Router 3 to Router 5 = Hop Count 3 ➢ Router 5 to Router 8 = Hop Count 4 ➢ Router 8 to Router 7 = Hop Count 5 ➢ Destination = PC-Jemine2 The network I have

    Network monitoring now is limited because of the number of servers it takes to deal with the large influx of router data. Router manufacturers have been attempting to combat this by adding counters to the routers that report on the number of data packets a router has processed during some time interval, but adding counters for every special task would be impractical and put more stress on servers since they would need thousands more to process the flood of data coming in. To combat this a system

  • Nonblocking Multicast Communication

    2848 Words  | 12 Pages

    Abstract – A main requirement in high performance networks is multicast communication, which involves transmitting information from a single source node to multiple destination nodes. A multicast assignment is a mapping from a set of network nodes called as source nodes, to a maximum set of network nodes called destination nodes with no overlapping allowed among the destination nodes of different source nodes A network is said to be nonblocking for multicast assignments, if for any legitimate multicast

A token (special bit pattern that travels around the circle, computer catches token to send a message, after attaching massage token is then continues traveling around the network) design is used to prevent collision of date between messages that were send at the same time. In the token ring infrastructure
