Must choose routes for various origin destination pairs(O/D pairs) or for various sessions - Datagram routing: route chosen on packet by packet basis Using datagram routing is an easy way to split paths Virtual circuit routing: route chosen a session by session basis Static routing: route chosen in a prearranged way based on O/D pairs Eytan Modiano

The principal-agent problem describes a class of interactions between two parties to a contract, an agent and a principal. The legal origin of these terms suggests that the principal engages the agent to act on his(the principal s behalf. In economic applications, the agent is not necessarily an employe

This chapter will explain the origin of the spontaneity of physical and chemical change. Two simple processes are examined. It shows that a property, the entropy can be defined, measured, and used to discuss spontaneous changes quantitatively. This chapter also introduces a major subsidiary thermodynamic property, the Gibbs energy
