Q1 Develop traffic flow mapping and performance requirements for flows.
Q2 Calculate data bandwidth requirements from and to each site.
Q3 This company got a block of network address 150.75.0.0 from ICANN. Is this a Class A, B, or C address?
This address block is quite large for them. Given the departments and number of people in each department at all locations (as noted above), develop a variable-length addressing scheme with some reserved addresses to accommodate possible future hires and addition of
devices. MyCo suggests reserving at least 30% more IP addresses for each group. Bc reasonable in your allocation and do not over-allocate addresses. Provide different address blocks for each department at each location for routing and security reasons, and make addresses contiguous: so that the unused address block can be traded or used for future use.
The next three questions relate to voice communications. Note that this topic was not covered in the class, but it is included to encourage self-learning. research, and analysis.
MyCo wants to know the impacts of putting Voice over IP with IP Phones. So, the same IP infrastructure (LAN-WAN) will carry voice as well. Since most other technologies are getting out of favor, it is decided that the intra-building network will be Ethernet LAN based.
For VOIP, first you need to consider the codec to use. Although there are many voice cakes, MyCo wants the safest bet and suggests that you design with the most known and oldest codec G.711 since they are very concerned about the voice quality with Vol?. Calculate the voice payload from G.711 codecs with 20ms. frames along with the RTP, UDP, IP, and Ethernet overhead to measure the bandwidth per call with G.711.
Now, you need to calculate the bandwidth required for supporting VolP from each location based on the number of people at each location but considering that not everyone is going to call at the same time. Assume that no more than 25% of people are on the phone at any particular time at any location. That will give you the total bandwidth required from each location based on the number of people at each location and the required bandwidth per VolP call that you calculated from Q5.
