Answer the following questions in your own words, in no more than 4 sentences each.
1. Discuss the case when the load is low or high in a Bit Map Protocol What will be the waiting slot for a low-numbered station and high numbered station? According to Nabavi, M. (2015), “in our first collision-free protocol, the basic bitmap method, …show more content…
We have now considered two basic strategies for channel acquisition in a cable network: contention, as in CSMA, and collision –free methods. Each strategy can be rated as to how well it does with respect to the two important performance res, delay at low load measures, delay at low load and channel efficiency at high load .
What 3 properties/features are added to MACAW which was not there in MACA?
The authors base MACAW off of the MACA protocol”, which uses an RTS-CTS exchange before sending the actual data packet to avoid collisions. To this, MACAW adds numerous additional features (Yong, …show more content…
2, each station has a queue for each stream, to which the backoff algorithm (MILD) is applied independently.
3, MACAW also extends the RTS-CTS-DATA exchange in MACAW to RTS-CTS-DS-DATA-ACK, which successfully increases throughout and fairness in various cell configurations (Yong, 2010).
3. What is Time Domain reflectometry?
Time – domain reflectometry or TDR is a measurement technique used to determine the characteristics of electrical lines by observing reflected waveforms Time-domain transmissometer (TDT) is an analogous technique that measures the transmitted (rather than reflected) impulse. Together, they provide a powerful means of analyzing electrical or optical transmission media such as coaxial cable and optical fiber ("Time-domain reflectometry", 2016).
