Switching via an interconnection network
The switching techniques overcome the bandwidth limitation of a single shared bus. This technique use a more sophisticated interconnection network such as those that have been used in the past to inter connect processor in a multiprocessor computer architecture.
A crossbar switch is an interconnection network consisting of 2 N buses that connect N input ports to N output ports as shown in figure. A packet arriving at an input port travels along the horizontal bus attached to the input port until it intersects with the vertical bus leading to the desired output port. If the vertical bus leading to the bus output port is free the packet is transferred to the output port. If the vertical bus is being is used to transfer a packet from another port to this same output port. The arriving packet is blocked and must be queued at the input port.
Token Bus Frame Format No length field Data is able to be much larger (timers prevent hogs) Frame control Ack required? Data vs Control frame and how is
It is one of the models based on PRAM. In this model, the processors access the memory locations concurrently for reading as well as writing operations. In the algorithm, which use
Q. Why congestion occurs? Congestion Emerge if the load on the network is greater than the capacity of the network - Load that is the number of packets sent to the net
Design the user interface for mode switching and data entry any way that you like. For example, to switch an application from transmit mode to receive mode, you can give it special
DEFINITION: Latency = Delay. Because a store and forward switch reads the entire frame before forwarding, a larger frame takes longer than a shorter frame.
What is logical link control? One of two sublayers of the data link layer of OSI reference model, as explained by the IEEE 802 standard. This sublayer is responsible for mainta
If the number of incoming clients invokes exceeds the number of processes in a server class, the TP Monitor might be dynamically start new ones and this is known as Load balancing.
Perform Basic Switch Configurations Step 1: Cable a network that is similar to the one in the topology diagram. You can use any current switch in your lab as long as it has
Q. Illustrate Go Back - N protocol? Go Back - N - Sender window size - Receiver window size = 1 - Why the names go back- N? - When the frame is spoilt the sende
