Reliability Evaluation of Communication Network Considering Capacity and Delay of Transmission Abstract This paper introduces a reliability index Capacity and Delay Related Reliability (CDRR) for communication networks. An algorithm is proposed for evaluating the CDRR. This algorithm needs the binary system states generated by the minimal paths, message flow capacity and time delay of these states. A criterion for computing the delay time of the binary system states is also proposed. In the paper, attempt has been made to justify that the index, CDRR will be an appropriate reliability index for evaluating the performance of communication networks. KeywordsConnectivity Performance-index CDRR Communication-network Flow-capacity Time-delay I. INTRODUCTION Communication network is an example of flow networks where the flow is the message transported through the network consisting of nodes acting as switching stations and edges as communication links. Disruption of the communication network depends upon the link failure as well as the non-fulfillment of constraints of performance by the system. There are several performance indexes of flow networks already defined [1-5]. Most of these consider the effect of link capacity only in evaluating the performance index. This index has been described in literature as Capacity Related Reliability (CRR). In performance evaluation of communication networks transportation of links has also been considered [6-9]. But the operating environment of communication networks is such that the performance of the network is affected by the constraints of both capacity and transportation time. There is a need of integrating both these in reliability index. Here one such reliability is being propo... ... middle of paper ... .... 37, pp. 6569,Apr. 1988. [8] R.

-Assume the transmission range of each node (usually all the nodes have the same range).
b) Bottleneck is the resource that has the smallest capacity. It creates the weakest link in the overall process chain and determine the process capacity. In the other word, the process capacity is equal with the minimum capacity of its resource. Since the flow unit needs to be processed by each resource (for example there are a total “n” resources in the process), thus, the process capacity can be written as

Canada is also very unique in the global economy in light of their communication technologies. Canada is a unique country because it allows two main companies control its communication industry. The two big players in the game are Rogers, who control eastern Canada, and Shaw, who control western Canada.

Communication accommodation theory and face-negotiation theory supply principles that guide actions while communicating with one another within a diverse community. The melting pot of the United States contains a deeply diverse community that these theories apply to every single person. In order to live in a communication stable nation we need to accommodate others with our behaviors, we need to evade conflict and let the Lord handle it. Rejoice with them that do rejoice, and weep with them that weep. Be of the same mind one toward another.
Troubleshooting media problems on a bus networks can be very tedious, since a break in the backbone will bring down the entire LAN. For this reason, bus topology is not considered one of the more robust network topologies, compared with star or mesh. A loose or missing terminating resistor can also bring down a LAN.
When electronic devices transfer information to another electronic device, the devices need to know when data flow is beginning and ending. This is done with signals for synchronization.i
At the dawn of the information age, to be young, as Wordsworth said in another context, is very heaven. Getting to know what goes inside computers, the engines of the Information Technology revolution, and knowing how to work with them enables one to understand the technology that makes it all possible. Understanding this, I chose to do my undergraduate study in Electronics and Communications engineering.
Networks in organisation are dynamic and complex entities which can be quite challenging to configure and manage. (Kim & Feamster 2013). These corporate networks consist of multiple routers, switches, firewalls, middleboxes and a particular advantage of network management is the ability to monitor the entire business network. As all the devices are interconnected with many event occurring simultaneously, problems with once device can eventually lead and spread throughout...

Assigning the precise amount of network capacity in the right place at the right time is no simple task. Network Planners cannot afford to overbuild, as this would consume scarce investment resources that could be better used elsewhere. They also cannot delay expansion as this may result in poor service to customers and under-utilize other network assets. A balanced approach is needed in order to meet the rapidly growing and changing traffic demands. Advanced network planning and design software provides benefit to network planners in the following ways:
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 a...
People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
