TL;DR: In this paper, a geometry-based routing algorithm (GRA) is used to route traffic from a source node to a destination node in an ad-hoc mobile network, where the source node maintains location information and routing information for all nodes in a local area and approximate location information for at least some nodes outside the local area.
Abstract: In an ad-hoc mobile network, a geometry-based routing algorithm (GRA) is used to route traffic from a source node to a destination node. In the GRA, a source node maintains location information and routing information for all nodes in a local area and approximate location information for at least some nodes outside the local area. If the source node has to send a packet to a destination node outside their local area, then the source node uses the approximate location information of the destination node to identify which node in its local area is closer to the destination node than the source node. The source node then sends the packet to the identified local node for further routing.

TL;DR: In this paper, a Virtual Private Network (VPN) is built above the underlying packet-based network and includes selected portions of the packetbased network resources, such as network elements and customer premises equipment.
Abstract: In a packet switching (packet-based) network, such as a frame relay (FR) network, which includes network resources made up of networked elements and customer premises equipment interconnected by one or more physical paths, a Virtual Private Network (VPN) is built above the underlying packet-based network and includes selected portions of the packet-based network resources. The VPN is a collection of logical nodes and virtual paths (VPs) and includes one or more virtual circuits (VCs), each VC being a logical connection between VC terminators including network elements and customer premises equipment. Segments of the VCs are carried by VPs, each VP being a logical connection established between two VP terminators which are located in either network elements or customer premises equipment. One or more VPs are multiplexed on a physical path (PP). Each VP is allocated a positive guaranteed bandwidth (VP-CIR), and each VC on a VP is also allocated a bandwidth (VC-CIR) greater than or equal to zero. Packets of information to be transmitted over a VC are provided with a unique address field to thereby identify the VCs and VPs associated with the VPN over which the packet of information will travel. Congestion control of the network is provided such that congestion control and management are carried out on a per VPN basis, and congestion outside of a VPN's logical domain does not affect the performance of the VPN.

TL;DR: In this paper, an integrated SOA-based Mach-Zehnder interferometer (SOA-MZI) at 20 and 40 Gb/s was used for all-optical XOR functionality.
Abstract: All-optical XOR functionality has been demonstrated experimentally using an integrated SOA-based Mach-Zehnder interferometer (SOA-MZI) at 20 and 40 Gb/s. The performance of the XOR results has been analyzed by solving the rate equation of the SOA numerically. The high-speed operation is limited by the carrier lifetime in the SOA. In order to solve the limitations imposed by carrier lifetime, a differential scheme for XOR operation has been experimentally investigated. This scheme is potentially capable of XOR operation to >100 Gb/s.

TL;DR: The main objective of METIS is to lay the foundation for this future global mobile and wireless communications system, and to generate a global consensus here.
Abstract: In 2020, mobile and wireless traffic volume is expected to increase thousand-fold over 2010 figures. Moreover, an increase in the number of wirelessly-connected devices to counts in the tens of billions will have a profound impact on society. Massive machine communication, forming the basis for the Internet of Things, will make our everyday life more efficient, comfortable and safer, through a wide range of applications including traffic safety and medical services. The variety of applications and data traffic types will be significantly larger than today, and will result in more diverse requirements on services, devices and networks. METIS is set up by leading global players to prepare the migration towards tomorrow's multi-purpose global communication infrastructure, serving humans and things. The main objective of METIS is to lay the foundation for this future global mobile and wireless communications system, and to generate a global consensus here. In particular, METIS will provide new solutions which fit the needs beyond 2020.

TL;DR: A meaningful measure of received video requires a more thorough analysis of netiork errors than average error rates, and results include patterns of packet lossover tim~ conditional packet 10SS.
Abstract: 1. BSTWCT This paper presents results from a study of stieaming h~EG compressed video over the pubHc Inteme& using the RTP and UDP tianspoti protocok. TmTofie minute video etips were h~EG coded at rates of 384 Kbps and 1 l~ps. The resultant coded streams were transmitted at their respective data ra$esbe~een four sites in the United States and Europa hIeasurements w’ere taken be~een sites during aHhours of the day for seveml weeks at a time to generate a clear pictire of the time varying nature of Internet errors. The paper concentrates on ne~ork loss/error characteristics that specifica~y affect the quali~ of the received ~~EG compressed stieams. Due to the nature of h~EG data streams, losses in certain pati of the data stieam are more disturbing when viewed than losses in other parts of the data stieam. For instance, since N~EG video is inter-fmme coded, artifacts due to netiork loss/emors, can persist for many frames. Thus, a meaningful measure of received video qua~ty requires a more thorough analysis of netiork errors than average error rates. Our results include patterns of packet lossover tim~ conditional packet 10SS
