Supporting Multiplexed Connections - Essay Example

Topic Q Connection setup and multiplexing Before transmission of any data packets, the sender should first communicate with the receiving end in a three-way handshake procedure which enables them to create the connection and later on a data transmission begins (Comer, 2006, p 17). Reliable data transfer.This service heightens the quality of service that the network provides so as to correspond with the application needs. FramingIn a network transmission, applications may want to send integrated data and the transport layer aids in the maintenance of these boundaries.

The initial data must be framed if it is part of the service framework. Congestion controlWhen data packets are sent on a network, the transmission first starts slowly so as to prevent any flooding that might occur. In time, the transmission becomes faster if there is no congestion. ReferenceComer, D. E., 2006.

A cookie can be defined as a unique symbol that a web server puts on your computer.

It consequently follows your every activity on the website that initiated it and the website proprietors receive this information.In E-commerce websites, cookies can and are frequently used to help in keeping the purchase details of each customer. E-commerce website requests for any present cookies when a customer accesses a page. The cookies tell the sites shopping cart what items are in the cart, and when the customer adds a new product or removes it, the server sends a new cookie to the browser that is up to date.

When its checkout time, the updated cookie, tells the shopping cart what products have been purchased (Greenstein, 2001, p 35).ReferenceGreenstein, M., & Vasarhelyi, M.A., 2001-6. Electronic Commerce: Security, Risk Management, and Control, McGraw-Hill Education. Q. 3The transport control protocol (TCP) is a connection-oriented service. This means that it usually has the client and server exchange transport-layer information with one another prior to the flow of the application level messages.

Consequently, the client has the responsibility of starting the communication with the server and in order for the server to be able to respond to the client’s first communication, the server needs to be ready. This means that the server application cannot afford to be in an inactive state and must be running even before there is an attempt to generate the communication by the client. Thus, the server application must be executed before the client program (Rajinder, 2007, p 64). ReferenceRajinder, Y., 2007. Client/Sevrver programming with TCP/IP sockets.
