Events like aircraft pushback, taxi, takeoff, avionics of the aircraft directly to the ground-based entities landing, and gate arrival were transmitted via voice over radio through Very High Frequency (VHF) radio frequencies frequencies to operators who would relay this information back without any crewmember involvement. The aircraft was to the airlines. The pilots were responsible for self-reporting programmed to take advantage of switches and automation their own times and movements. Understanding that people points on the aircraft, resulting in the creation of a set of can sometimes be forgetful, or worse, willfully manipulative, messages referred to as the OOOI report.

Data Networks
Second Ed ition Data Networks DIMITRI BERTSEKAS Massachusetts Institute of Technology ROBERT GALLAGER Massachusetts Institute ofTechnology PRENTICE HALL, Englewood Cliffs, New Jersey 07632 2 Node A Node B Time at B --------- Packet 0 Point-to-Point Protocols and Links 2.1 INTRODUCTION This chapter first provides an introduction to the physical communication links that constitute the building blocks of data networks. The major focus of the chapter is then data link control (i.e., the point-to-point protocols needed to control the passage of data over a communication link). Finally, a number of point-to-point protocols at the network, transport, and physical layers are discussed. There are many similarities between the point-to-point protocols at these different layers, and it is desirable to discuss them together before addressing the more complex network-wide protocols for routing, flow control, and multiaccess control. The treatment of physical links in Section 2.2 is a brief introduction to a very large topic. The reason for the brevity is not that the subject lacks importance or inherent interest, but rather, that a thorough understanding requires a background in linear system theory, random processes, and modem communication theory. In this section we pro vide a sufficient overview for those lacking this background and provide a review and perspective for those with more background. 37 38 Point-to-Point Protocols and Links Chap. 2 In dealing with the physical layer in Section 2.2, we discuss both the actual com munication channels used by the network and whatever interface modules are required at the ends of the channels to transmit and receive digital data (see Fig 2.1). -

Discussion Chapter#9 Services of Data-Link
The Islamic University of Gaza ECOM 4314: Data Communication Faculty of Engineering Instructor: Dr. Aiman Abu Samra Department of Computer Engineering T.A.: Eng. Alaa O. Shama Discussion Chapter#9 The data-link layer of a node (host or router) is responsible for delivering a datagram to the next node in the path. The data-link layer is located between the physical and the network layers. The datalink layer provides services to the network layer; it receives services from the physical layer. data-link layer of the source host needs only to encapsulate the datagram received from the network in a frame, the data-link layer of the destination host needs to decapsulate the datagram from the frame, but each intermediate node needs to both encapsulate and decapsulate, because each link may be using a different protocol with a different frame format. Even if one link and the next are using the same protocol, encapsulation and decapsulation are needed because the link-layer addresses are normally different. Services of Data-Link: 1. Framing The data-link layer at each node needs to encapsulate the datagram (packet received from the network layer) in a frame before sending it to the next node. The node also needs to decapsulate the datagram from the frame received on the logical channel. 2. Flow control If the rate of produced frames is higher than the rate of consumed frames, frames at the receiving end need to be buffered while waiting to be consumed (processed). Definitely, we cannot have an unlimited buffer size at the receiving side. -

Data Links Functions, Attributes and Latency
Nichols, Ryan, Mumm, Lonstein, & Carter Chapter 13: Data Links Functions, Attributes and Latency Student Learning Objectives The student will learn about the data-link function of the UAS which allows for bi-directional communication and data transmissions between UAV and its ground station. The Data Link is a vital component of an UAS. The student will learn the respective functions of each component part and considerations are necessary and how to evaluate their importance when developing a UAS. While the focus of the lesson will be on military applications, the considerations will be equally important for those designing and deploying UAS for civilian purposes. While the design of the Datalink must have requisite attributes that allow the system to function as intended in various environments globally, it must be able to do so securely and effectively. Issues such as Data Link security, interception, deception and signal latency are all attributes that must be balanced to achieve fast and secure data communications between the components of the UAS. What are the Types of UAV’s and how are they Categorized? UAV’s are most often divided into four categories based upon their mission duration and operational radius. High Altitude, Long Endurance (“HALE”) most often deployed for reconnaissance, interception or attack; Medium altitude, moderate range most often used for reconnaissance and combat effect assessment; Low cost, short range small UAV’s. (See Figure 13-1.) Components of the UAS Data-Link and their functions The UAV and Ground Control Station There are four essential communication and data processing operations the UAS must be able to efficiently and effectively carry out.
