Question 4. This question concerns naming and discovery in distributed systems. a. Explain briefly how the database servers in Figure 1 could use network multicast to allow a local client such as Client 1 to discover them even if it had no other information about them. b. Each of the hosts in Figure 1 has a public (routable) IP address and a unique domain name (as shown). In addition the domain name "database.distsys.com" can be used to distribute requests to all of the hosts. What DNS records are required and why? c. Discuss whether or not the company with the domain distsys.com should pay a commercial DNS provider or operate their own DNS servers. Which would you recommend and why?

With persistent communication, a receiver generally has its own local buffer where messages can be stored when the receiver is not executing. To create such a buffer, we may need to specify its size. Give an argument why this is preferable, as well as one against specification of the size.

For the sake of this illustration, a database used by an airline that makes use of "snapshot isolation" makes for an excellent starting point. What happens if a non-serializable execution ends up giving the airline a better overall performance?
.: Consider a chain of processes P₁, P2, ..., Pn implementing a multitiered client-server architecture. Process P; is client of process Pi+1, and P; will return a reply to Pi-1 only after receiving a reply from P+1.

Q2. Determine if the following schedule is allowed to finish when the timestamp based protocol is used. Assume each transaction’s timestamp is its starting time, and the entire schedule started at time point 2. T2:R(X) ; T2:R(Y) ; T3:R(Y) ; T3:R(X) ; T3:W(X) ; T3:W(Y) ; T2:W(Y) ; T2:W(X)
Computers linked together in networks The term "data collision" refers to the situation in which several senders simultaneously access the same media. How can this be avoided, and at what Layer(s) and with what protocols can this be accomplished? Can these precautions ensure that there will be no accidents throughout the trip? If not, what other ways are there for us to handle this matter?
