![]() The bottom of the class symbol can be annotated with the interface's signature information: method names, arguments, argument types, and so forth. UML also allows a class symbol (box) to be stereotyped as an interface the open-headed dashed arrow shows that an element realizes an interface. UML uses a "lollipop" to denote an interface, which can be appended to classes and subsystems, among other things. Interfacesįigure 9.4 shows how module interfaces can be represented in UML. Recall that a module is a code or implementation unit and a module view is an enumeration of modules together with their interfaces and their relations. Still, in most cases we can use the constructs that UML does offer to achieve satisfactory effects, at least in crafting the primary presentations of architectural views. UML provides no direct support for components, connectors, layers, interface semantics, or many other aspects of a system that are supremely architectural. It is up to the architect to augment the UML pictures with the necessary supporting documentation (the element catalog, the rationale, and so forth) that a responsible job requires. However, it must be said that UML makes its main contribution in a view's primary presentation, and its secondary contribution in the behavior of an element or group of elements. Nevertheless, today the Unified Modeling Language (UML) has emerged as the de facto standard notation for documenting a software architecture. Architecture in some sense expresses what is essential about a software system, and that essence is independent of languages and notations to capture it.

Push the changes back to your remote repository.Clone it now to your local machine on which you are going to work.Fork the source code of the program for Knock-Knock Protocol from GitHub. ![]() Please take the following steps to complete this assignment. And let me tell you that it is not as bizarre a harbinger as you may think. However, as you will progress through your academic years and look back at the Knock-Knock protocol in the hindsight, you will realize that it was a harbinger for many useful concepts not only in communication networks but also for ideas in various other feats. Seemingly, it may appear trivial to you to work on something apparently as bizarre as the Knock-Knock protocol. Please consider completing the following assignment. So please consider getting your hands dirty with some code if you really want to become good at computer programming. And in the programming world the mantra is that there is no shortcut for hands-on work. But acquiring even this level of sleight of hands requires some practice. You will be amazed to learn that how a seemingly application like an echo server can be changed into a bit more advanced application like the Knock-Knock server with a mundane sleight of your hands. The only rule the KnockKnock protocol follows is that it has to react with a funny response, no matter what.Ī surprising fact about the knock-knock protocol is that it built upon the plain old echo server. What could be in a Knock-Knock protocol? In the case of the KnockKnock protocol, there are no such explicit rules for communication except for the fact that the communication happens through sockets. What is in a protocol by the way? In communication networks, a protocol is defined as a set of rules through which multiple machines communicate with each other. As suggested earlier, this scheme is implemented using a Knock-Knock protocol. And the latter, instead of opening the door, replies with messages that appear either funny or annoying to the guest, depending on the state of the mind he is in. The idea ensues from the fact that a person knocks at the door of a funny, but nice, person. The server, on the other hand, sends back messages to the client what it considers to be quite funny. In this scheme, a client merely tries to connect to a server and sends various queries to it. In this assignment, you will learn how to implement a simple Knock-Knock client and a server using the so-called Knock-Knock protocol.
