Object data = 100 Kbits
Distance (d) = 10 meter
Number of connection (N) =10
Non-Persistent Connections:
Non-persistent connections are defined as only being able to accommodate up to 10 objects, and each object must enter the connection separately as the client or the server must close the connection for each object through the connection.

Consider sending real-time voice from Host A to Host B over a packet-switched network (VolP). Host A converts analog voice to a digital 64 kbps bit stream on the fly.
Host A then groups the bits into 56-byte packets. There is one link between Hosts A and B; its transmission rate is 2 Mbps and its propagation delay is 10 msec.
As soon as Host A gathers a packet, it sends it to Host B. As soon as Host B receives an entire packet, it coverts the packet's bits to an analog signal.
How much time elapses from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B)?
TCP / IP uses the client-server communication model, in which a user or computer (a client) receives a service (such as sending a web page) from another computer (a server) on the network.
In short, the TCP / IP protocol suite is classified as stateless, which means that each client request is considered new because it has nothing to do with previous requests. Being stateless, network routes are released so that they can be used continuously.
Answer the following questions briefly.
How does resource reservation work in the TCP / IP model?
Which TCP / IP layer is responsible to reserve resources across a network using the TCP / IP model?
What protocol assigns an IP address to the client connected to the Internet?
Checksum is used by various protocols on the Internet, but not at the one of TCP / IP Explain.
Suppose that the average object size is 850,000 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 Δ/(1 – Δ ), where Δ is the average time required to send an object over the access link and is the arrival rate of objects to the access link.
a. Find the total average response time.b. Now suppose a cache installed in the institutional LAN, Suppose the miss rate is 0.4. Find the total response time.

- We send real-time voice from Host A to Host B over a packet-switched network (VolP). Host A converts analog voice to a disital 64 Kbps bitstream on the fly then groups the bits into 64-byte packets.

When the counter gets to zero, the packet is discarded. Time is discrete, with each line handling one packet per time interval.

- 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?arrow_forwardA messaging system reads message as 4-digit positive integer d1d2d3d4 and stores encoding of the message e1e2e3e4 for security reason.
