End-To-End Network Architecture Design

• How many subscribers can be supported over a packet cable infrastructure?

• How will an existing network react to the deployment of Voice over IP?

• What is the impact of running voice and data services over a common network infrastructure on service quality?


Systems Level Simulation for Network Devices

• Will a proposed packet scheduling algorithm allow us to meet target service requirements?

• How should device queues be sized to minimize cost while meeting throughput specifications?

• What backplane access scheme will yield optimal system performance?


Protocol Development and Optimization

• How can we enhance admission control procedures to optimize backbone performance?

• Are commercial data protocols adequate for regulating the intercommunication of embedded systems on a mobile platform?

• How do standard wireless protocols need to evolve to efficiently support advanced data applications?


Network Application Optimization and Deployment Analysis

• Is my application optimized to minimize impact on network usage?

• My application runs great on my test network, but how will it perform when it is deployed on a network with background traffic?

• How will application deployment effect my network performance?

CASE STUDIES


Case Study: End-to-End Network Design


Case Study: Test-Drive Your Design with Application Profiles


Case Study: QoS Scheduling for a Gigabit Switch


Case Study: Designing Wireless Communication Protocols


1 TRANSITION DELAY MODELcomputes the time required for a transmission to complete

2 LINK CLOSURE MODELdetermines which receivers can be reached by the transmission (the rest of the Pipeline will be executed separately for each receiver that passes this test)

3 CHANNEL MATCH MODEL determines which receiver channels can demodulate the transmission, and which ones should treat it as noise

4 TRANSMITTER ANTENNA GAIN MODEL computes the gain of the transmitter's antenna in the direction of the receiver

5 PROPOGATION DELAY MODELcomputes the time required for the transmitted signal to propagate between the transmitter and the receiver

6 RECEIVER ANTENNA GAIN MODEL computes the gain of the receiver's antenna in the direction of the transmitter

7 RECEIVED POWER MODEL computes the average received power of a transmission (typically factoring in antenna gains, channel frequency, transmitter power, distance, etc.). Fading effects can be incorporated here.

8 BACKGROUND NOISE MODEL computes the in-band background noise for a receiver channel

9 INTERFERENCE NOISE MODEL computes the interference noise which affects a transmission fragment (typically, the total power of all other concurrent, in-band transmissions)

10 SNR MODEL computes the SNR of a transmission fragment (usually based on the ratio of received power to the sum of background and interference noise)

11 BER MODEL computes the mean bit error rate (BER) over each constant SNR fragment of the transmission

12 ERROR ALLOCATION MODEL determines the number of bit errors in each fragment of the transmission

13 ERROR CORRECTION MODEL determines whether the allocated transmission errors can be corrected and if the transmitted data should be forwarded into the node for higher level processing
