4. Under some conditions, it makes more sense to send enough information to correct data on receipt (such as using a Copyrighted Hamming code). In others, it makes more sense to discover the error and throw the data away. These conditions would not be just the link type, however, or just the application; they would be a combination of the two. What link characteristics combined with what kinds of application characteristics, would suggest the use of FEC? Which ones would suggest the use of error detection combined with retransmitting the data?It might be best to think of specific applications and specific link types first, and then generalize from there 5. How many bit flip changes can a parity check detect? 6. Implicit and explicit signaling have different characteristics, or rather different tradeoffs. Describe at least one positive and one negative aspect of each form of signaling for error detection and/or correction 7. In a large-scale deployment of anycast, it is possible for packets from a single stream to be delivered to multiple receivers. There are two broad solutions to this problem; the first is for receivers to force the sender to reset their state if a packet appears to be misdelivered in this way. Another is to constrict the interface between the sender and receiver in a way that allows state to be contained to a single transaction. One form of this latter solution is called atomic transactions, and is often implemented in RESTful interfaces. Consider these two possible solutions, and describe the kinds of applications, giving specific examples of applications, that might be better suited for each of these two solutions
