1A) Find a Web page that shows the percentage of IP traffic that is IPv6 (vs IPv4) for the Internet as a whole, or for one of the major Internet applications. You must find data for actual traffic, not just the percentage of sites that are capable of using IPv6. State the percentage figure and the context (the Internet, a specific application, ...) and show the URL for the page you found. 1B) An application that will use IPsec must provide confidentiality and authentication of origin and integrity. State the full name of the IPSec protocol that must be used to process data for this application, and explain why that protocol must be used and not the other protocol at the same level.

In addition to providing the compositions of the liquid and vapor phases, T-x-y (and H-x-y) diagrams allow us to determine the relative amounts of vapor V and liquid L that compose the total sample at equilibrium. If a binary mixture with total mole fraction z separates into two phases in equilibrium, then the "lever rule" states that the ratio of the difference between the vapor and total composition (the length of AB in the diagram) to the difference between the total and liquid compositions (length AC in the diagram) is equal to the ratio of L to V: AB / AC = L.V, Use a material balance to derive this rule.
