	Glossary of Terms - D (Zarlink Semiconductor)
		Datagrams are sent as packets on the link layer, and a datagram may be sent as one or many packets.
		A facility provide by the data link control protocol which allows any pattern of bits, bytes, or characters to appear within the information field of a transmission frame and ensures that NO pattern in this field will be mistakenly treated as control information by the receiver.
		An encryption method (also known as "5C") developed by Sony, Hitachi, Intel, Matsushita and Toshiba for IEEE 1394 interfaces.

		Dispersion-limited operation: Operation of a communications link in which signal waveform degradation attributable to the dispersive effects of the communications medium is the dominant mechanism that limits link performance.
		In telecommunication, a digital multiplex hierarchy is a hierarchy consisting of an ordered repetition of tandem digital multiplexers that produce signals of successively higher data rates at each level of the hierarchy.
		The term multiplexer has uses in several fields of application: Electronics In electronics, a multiplexer or mux is a device that combines several electrical signals into a single signal.

		Encryption is a formula used to turn data into a secret code.

	Wireless multimedia networking
		Encryption reversibly transforms one bit stream into another such that a reasonable facsimile of the original bit stream is unavailable to a receiving terminal without knowledge of appropriate keys [13].
		Encryption is one component of a conditional access system, with which a service provider can choose whether and when any individual receiver can access the provided service, and is also useful in insuring privacy.
		The statistical multiplexing advantage in congestion-dominated subnets depends on the peakiness of the offered bit streams, at least for a constant loss and delay objective, and the manner in which the bit rate varies with time is an important factor in the traffic capacity.

		Consequently, the PEP and its counterpart behind the disconnected link can employ a modified TCP version which retains the state and all unacknowledged data segments across the period of disconnection and then performs local recovery as the link is reconnected.
		The period of link disconnection may or may not be hidden from the application and user, depending upon what application the user is using the TCP connection for.
		Placement of a PEP on a high speed link or a link which supports a large number of connections may require network topology changes beyond just inserting the PEP into the path of the traffic.

	Chapter 6
		Multiplexing techniques can be used to minimize the number of data links needed to communicate field-device status to the security center.
		If the communication link to the security center is temporarily lost, local processors can continue to operate in a stand-alone mode, storing data for transmission after the link is restored.
		All local processors may be linked to the central computer using one common DTM link, or the DTM may consist of several links.

	In Focus \| November 2002 \| Digital Cinema
		The simplification comes about because the required capacity of the link and the need for stringent timing characteristics across it are reduced by moving the “player.” This simple move allows the link between server and projector to be implemented with off-the-shelf computer technology.
		Reducing the cost of the link is not the only benefit of the “data model.” This model also eliminates the need for a technology called “link encryption.” To best understand link encryption, we need to understand the security side of digital cinema systems.
		Because the original encryption is still intact, the data is secure as it travels across the fiber or wire.

	Tor: The Second-Generation Onion Router
		The entire contents of the relay header and the relay cell payload are encrypted or decrypted together as the relay cell moves along the circuit, using the 128-bit AES cipher in counter mode to generate a cipher stream.
		We use PK encryption in the first step (rather than, say, using the first two steps of STS, which has a signature in the second step) because a single cell is too small to hold both a public key and a signature.
		Link padding could frustrate passive observers who count packets; long-range padding could work against observers who own the first hop in a circuit.

		The framework should minimize protocol overhead, in terms of the number of additional bytes to be sent in addition to the IP packet and processing overhead in terms of parsing effort of variable length headers or options fields (see iv).
		There is a need to signal the PID and TS Multiplex that is associated with each IP flow to the network layer at the sender and receiver (address resolution).
		Since high speed links are often limited by the packet forwarding rate of routers, there has been a tendency for Internet core routers to support MTU values larger than 1500 bytes.
