Ethics - Essay Example register required knowing the numbers item numbers for grains and produce; the customers were supposed to write them down, but many of them neglected this rule, and as such it was dependent on the cashier to either memorize or run and find the number when the customer forgot. Subsequently, during the busy periods the lines got long, and I had to rely on Joyce to help me with the item numbers. In addition to the item numbers, she helped me out with all the small things about the job that you don’t learn in training – which were the important managers, when to pretend you’re working hard, and when to slack off. Over the first few weeks we became very close and Joyce introduced me to her family. She had two daughters she was taking care by herself, as her husband had left her a few years earlier. One day Joyce came in visually distressed and wouldn’t tell me what was wrong. During our break I ate with her and finally got her to tell me the problem. She told m e that she had come on difficult times of late, as her husband had stopped paying child support and she was facing eviction from her apartment. Joyce was considerably older than me and I didn’t have much experience in these situations, but I felt very bad for her situation, and consoled her and told her that I’m sure things would be all right. The next day I worked Joyce was in and she seemed better. I noticed that she was much more standoffish than she had previously been, and I thought that maybe she just didn’t want to discuss what she told me before. During one of the busy periods one of Joyce’s daughters came through the checkout line, and I noticed Joyce not charging her for a number of items and place them in a bag. I wasn’t sure if I had seen the incident accurately, so I chose not to say anything. The next day I worked I watched Joyce closely and noticed that during the same time her daughter came through again, and Joyce similarly didn’t charge her for the items. At this point I was

Method of Implementing QoS - Essay Example Data loss, delays are few of the events that could take place as a result of absence of quality of service mechanism. The categorization is as a result of number of considerations that are taken into account namely the Mac address, the ports both Ethernet and T.C.P. Various methods are available for implementing Q.O.S. All have their own advantages and drawbacks and most of them do serve up the purpose of improving overall performance of the network through specific means. The good point about Q.O.S is the fact that they can prioritize both the voice and data communication. However it is often noted that the real need for bandwidth adjustment arises in case of data traffic. Q.O.S in simple words is a protecting shield and an assurance of its kind which provides smooth and constant flow no matter how heavy the resources are. Integrated Services model, best effort model are few of the mechanisms used for this purpose. All these mechanisms are devised for accommodating data traffic prim arily. The entire T.C.P traffic is at disposal of the quality of service and since nearly all of the traffic is passed through T.C.P layer, therefore need of an effective quality of service tool is unavoidable. Best effort mechanism: There are number of Q.O.S approaches that provide one particular line choosing decision. The best effort mechanism is comparatively better in this regard since it enables the users and servers with multiple paths option. This bunch of paths is well planned out, equally calculated and with all the constraints in mind is screened out to ensure best possible transmission over even a densely populated linkage (Smith & Aceves, 2000). The default nature of Best effort scheme: Default mechanism is followed in the scheme which can be termed as its strength as well as weakness at the same time. In some cases it is even referred to as no Q.O.S due to its first in first out and no separation behavior. This default scheme is followed across both the switches and ro uters. Sensitivity consideration is partially compromised in this form of quality service provision. Strength: The strength enjoyed by this scheme is the manner in which the entire route and its model are designed. With nearly all the traffic being packet enabled, best effort serves well fulfilling the requirements of the network especially the bandwidth hungry resources. Weakness: Weaknesses can be identified in case of only one link to a respective linage. With modern times putting up the challenges of further high bandwidth interfaces, multiple paths to a single source are the order of the day. The possible draw back in this form of servicing is the possibility of loss of data elements (usually packets) on the way. Scalability can be an issue in all kinds of Q.O.S. Since increasing number of users and channels demand more bandwidth hence the performance is directly influenced by the scalable capacity. The constraint that would be needed to be taken into account would be the avail ability of heavy bandwidth in the background so as to provide smooth flow to the dedicated paths set up. To some experts mainly Cisco, a dedicated over 20 percent bandwidth must be kept in store for the best effort scheme. Any less percentage of capacity could seriously drain out the entire network and hence this mechanism would not live up to its desired purpose. Another problem that could arise in this form of s
