  • Multiprotocol Label Switching Multiprotocol Label Switching (MPLS) is a standards-approved technology for speeding up network traffic flow and making it easier to manage. MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet to. MPLS is called multiprotocol because it works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and frame relay network protocols....

  • Wireless sensor nodes are small, embedded computing devices that interface with sensors/ actuators and communicate using short-range wireless transmitters. Such nodes act autonomously, but cooperatively to form a logical network, in which data packets are routed hop-by-hop towards management nodes, typically called sinks or base stations. A Wireless Sensor Network (WSN) comprises of a potentially large set of nodes that may be distributed over a wide geographical area, indoor or outdoor

  • Packet snooping can be detected in certain instances, but it usually occurs without anyone knowing. For packet snooping to occur, a device must be inserted between the sending and receiving machines. This task is more difficult with point-to-point technologies such as serial line connections, but it can be fairly easy with shared media environments. If hubs or concentrators are used, it can be relatively easy to insert a new node. However, some devices are coming out with features that remember MAC addresses and can detect whether a new node is on the network.

  • The ease or difficulty of packet snooping (also known as eavesdropping) on networks depends largely on the technology implemented. Shared media networks are particularly susceptible to eavesdropping because this type of network transmits packets everywhere along the network as they travel from the origin to the final destination. When concentrators or hubs are used in a shared media environment (such as FDDI, 10BASE-T, or 100-Mbps Ethernet), it can be fairly easy to insert a new node with packet-capturing capability and then snoop the traffic on the network.

  • Dynamicity of participants: Some P2P systems, such as [10], assume a fixed set of nodes in the system. However, one of the greatest potential strengths of P2P systems is when they eschew reliance on dedicated infrastructure and allow peers to leave the system at will. Even under these conditions, participants typically have broadly varying availability characteristics. Some peers are akin to servers: their membership in the system stays largely static. Others have much more dynamic membership, joining and leaving the system at will.

  • This Chapter addresses SMEs that are qualified to perform complementary manufacturing activities as producers, subcontractors or suppliers. They are used to participate in different supply chains taking the form of networks where every node manages in turn its own supply chain. More precisely, there are at least three main models (or viewpoints) to take into account:  Medium-large company and its supply chain members. When issuing an order the medium-large company should select the most convenient supplier depending on factors like cost, lead time, capacity, supply conditions, distance.
