Data Link Layer (DLC) Responsible for reliable transmission of packets over a link Framing: Determine the start and end of packets(sec 2.5) Error Detection: Determine when a packet contains errors ( sec 2.3) Error recovery: Retransmission of packets containing errors(sec 2. 4) DLC layer recovery May be done at higher layer

Optimal Routing View routing as\global\ optimization problem Assumptions: The cost of using a link is a function of the flow on that link The total network cost is the sum of the link costs The required traffic rate between each source-destination pair is known in advance Traffic between source-destination pair can be split along multiple paths with infinite precision

Grammar is the structural system of a language. The grammar of English is organized into five ranks: the sentence, the clause, the phrase, the word and the morpheme. Each rank is composed of one or more than one grammatical unit of the immediate lower unit. A full sentence can generally be segmented rank by rank down to its smallest constituents---the morphemes

defense system that has evolved to protect animals from invading pathogenic microorganisms and ancer. It is able to generate an enormous variety of cells and molecules capable of specifically recognizing and eliminat ing an apparently limitless variety of foreign invaders. These cells and molecules act together in a dynamic network whose omplexity rivals that of the nervous system. Functionally, an immune response can be divided into two related activities--recognition and response. Immune

immunology, refers to the act of transferring cells, tissues, or organs from one site to another. The desire to accomplish transplants stems from the realization that many diseases can be cured by implantation of a healthy organ, tissue, or cells(a graft)from one individual (the donor)to another in need of the transplant(the recipient or
