¡Escribe tu texto aData rate =

Shannon: Max bitrate depends on signal/noise ratio   

Nyquist: Max bitrate depends on n. sampling levels

CSMA CD

  • Is a MAC protocol
  • Exponential back-off strategy -> adapts to load on ethernet
  • RTT bounds determines a bound on throughput

IP tunnels

  • Packets traveling in a tunnel carry IP as load
  • Allows for any IP to be sent to any destination (regardless of the IP carried as load)
  • Never carries Ethernet as load
  • Always carry IP packets as load
  • The service offered by the IP protocol

Requirements Phase

Help the customer determine what he/she wants!

  • Sometimes have to help the customer!
  • Document it, including
  • – I/O requirements
  • – Hardware requirements
  • – Speed (throughput) requirements
  • – Software requirements
  • – Functionality desired

For our class

  • Are directions understood and followed?
  • -what the program is supposed to do
  • -input/output requirements
  • -formatting required
  • -correct name for program
  • Is it handed in on the due date?

Design Phase

1.High Level Design

  • Based on Req/Spec Document!
  • Design overall

Satellite Based Navigation

The development of the system architecture for the hypothetical Satellite Navigation System (SNS) by logically partitioning the required functionality. To keep this problem manageable, we develop a simplified perspective of the first and second levels of the architecture, where we define the constituent segments and subsystems, respectively. In doing so, we show a representative subset of the process steps and artifacts developed, but not all of them. Showing a more complete

Q1a. Define the term quality and elaborate different views on quality. Ans: There are different perceptions towards the quality of products. A. Customer-based definition of quality: A quality product must meet customer needs, expectations, and satisfaction. B. Manufacturing-based definition of quality: It means the customer is not fully aware of requirements, and requirements are defined by architects designed on feedback survey. C. Product-based definition of quality: Production must add some new
