Common use of Use Case Scenario Clause in Contracts

Use Case Scenario. The DVCL with CA system allows that remote students can work together. While the students will use their own computer, the university has to provide the CA. In our use case scenario we assume that a student uses the DVCL client outside the university (e.g. at home) utilising an internet connection to connect to the CA. A mobile environment using a cellular data plan is also possible. Figure 19 shows a corresponding use case diagram of the DVCL with CA. The left side represents the student’s home, connected via internet (cloud in the middle) to the university’s CA on the right side. A student, as a user of his desktop or laptop computer, uses the DVCL client to interact with a university’s CA using a control channel connection. An additional data channel connection will be established for each remotely connected virtual network.
