- Data collision occurs when multiple senders simultaneously attempt to access the communication medium. Various protocols have been developed to mitigate this issue. These protocols operate at different layers of the network stack. Could you please provide more specific information about the protocols you are interested in? Do these methods ensure reliable gearbox without any possibility of collisions? What alternative solutions are available if this approach proves ineffective?Computer networks When many senders try to access the same media at once, a phenomenon known as data collision occurs. What protocols, and at what Layer(s), are available to prevent this from happening? Do these methods provide reliable, collision-free transport? If not, what other means do you see for fixing the issue?Data collision occurs when many senders attempt to access the same medium at the same time; what protocol(s) and at what Layer(s) are available to prevent this?

- A local area network (LAN) makes use of something called a hub. Is there a route out of the collision zone that we don't have to go into? In the event that this is the case, could you kindly elaborate? In the event that this is not possible, what alternative types of technology are available, and how do they function?4. The original HTTP protocol used TCP/IP as the underlying protocol. For each page, graphic, or applet, a separate TCP connection was constructed, used, and terminated. This caused several problems: one referred to as the elephant and mice problem and two aspects of connection overhead. Describe both problems. Why were separate connections used? Would UDP rather than TCP be a good alternative? What solution would you propose to these problems to improve HTTP performance?Consider Figure 2.12, for which there is an institutional network connected to the Internet. Suppose that the average object size is 1,000,000 bits and that the average request rate from the institution’s browsers to the origin servers is 16 requests per second. Also suppose that the amount of time it takes from when the router on the Internet side of the access link forwards an HTTP request until it receives the response is three seconds on average (see Section 2.2.5). Model the total average response time as the sum of the average access delay (that is, the delay from Internet router to institution router) and the average Internet delay. For the average access delay, use ∆/(1 - ∆b), where ∆ is the average time required to send an object over the access link and b is the arrival rate of objects to the access link. Find the total average response time. I get ∆=1000000/15000000= 1/15, then ∆/(1 - ∆b)= (1/15)/(1-(1/15)*16)=-1, so the finally answer is : 3+(-1)=2s or 3+0=3s?
- Data collision occurs when many senders attempt to access the same medium at the same time; what protocol(s) and at what Layer(s) are available to avoid this? Do these procedures provide reliable, collision-free traffic flow? If that's not the case, what other solutions may be considered?Suppose a new CSMA/CD protocol is designed for a 100 Mbps bus network with topology similar to 10Base2. The minimum frame length is 40 bytes. What is the maximum length of the longest cable connecting two nodes so that the collision detection mechanism still works? Write symbolic equations (e.g. using d=distance, R=data rate, etc.) and derive the solution. Explain with words what is going on.How does each individual bridge and router work to reduce the collision domain in its own unique way?
- Consider a local network with a 1 Gbps access link to the Internet. Hosts on this network are accessing resources with an average size of 2 MB from a distant server at an average rate of 50 requests per second. a. What is the link utilization of the access link to the internet? b. Suppose these requests were to go through a caching proxy server. What would the link utilization to the internet be if half of all requests were served from the cache of the proxy server? с. resources never being needed for example.) Would this still provide any advantages to the end user? Would there be any disadvantages to the end user? Suppose the proxy server could not serve any content from cache (due to the sameNetworked computers Data collision happens when several senders access the same material simultaneously. How can this be prevented? Do these strategies guarantee collision-free transport? What further can be done?The use of layered protocols is justified for the following two reasons: Give specific instances to support your claim.
