21 Oct 1996TL;DR: The structure of micropipeline, 2-phase and 4-phase handshake control protocol, asymmetrical delay element and delay selection circuit are discussed and compared and how to use these circuit techniques to design the self-timed 8/spl times/8 Booth's multiplier is demonstrated.
Abstract: This paper presents some methods to improve the performance of an asynchronous system. Firstly, the structure of micropipeline, 2-phase and 4-phase handshake control protocol, asymmetrical delay element and delay selection circuit are discussed. Then we demonstrate how to use these circuit techniques to design the self-timed 8/spl times/8 Booth's multiplier. The performance of the circuit using these improvement techniques and different handshake control protocols are discussed and compared.

TL;DR: Artemis as mentioned in this paper uses a DNS-like domain name-IP mapping for replica selection and achieves low query latency by combining the name resolution process with the transport layer handshake process, all server replicas at different locations share the same anycast IP address, called Service Address.
Abstract: Today, Internet service deployment is typically implemented with server replication at multiple locations. Domain name system (DNS), which translates human-readable domain names into network-routable IP addresses, is typically used for distributing users to different server replicas. However, DNS relies on several network-based queries and the queries delay the connection setup process between the client and the server replica. In this article, we propose Artemis, a practical low-latency naming and routing system that supports optimal server (replica) selection based on user-defined policies and provides lower query latencies than DNS. Artemis uses a DNS-like domain name-IP mapping for replica selection and achieves low query latency by combining the name resolution process with the transport layer handshake process. In Artemis, all server replicas at different locations share the same anycast IP address, called Service Address. Clients use the Service Address to establish a transport layer connection with the server. The client's initial handshake packet is routed over an overlay network to reach the optimal server. Then the server migrates the transport layer connection to its original unicast IP address after finishing the handshake process. After that, service discovery is completed, and the client communicates with the server directly via IP addresses. To validate the effectiveness of Artemis, we evaluate its performance via both real trace-driven simulation and real-world deployment. The result shows that Artemis can handle a large number of connections and reduce the connection setup latency compared with state-of-the-art solutions. More specifically, our deployment across 11 Google data centers shows that Artemis reduces the connection setup latency by 39.4% compared with DNS.

18 Jan 2010TL;DR: In this article, a checker circuit for a handshake protocol was proposed, which is characterized by a compact circuit design that is associated with reduced susceptibility to circuit errors and a significantly reduced spatial requirement.
Abstract: The present invention relates to a checker circuit for a handshake protocol. The checker circuit detects common errors that occur when two communication unit on execute the handshake protocol. The checker circuit is characterized by a compact circuit design that is associated with reduced susceptibility to circuit errors and a significantly reduced spatial requirement. The invention also relates to a method for checking the execution of the handshake protocol.

TL;DR: A training concept is described on how to implement measures to increase Productivity for trainees on technician level by implementing network systems to chain distributed programmable controller units.
Abstract: A training concept is described on how to implement measures to increase Productivity for trainees on technician level. It's focusing on implementing network systems to chain distributed programmable controller units. Seven PLC controlled stations made an assembly line for a model cylinder (25 mm /spl times/ 40 mm). The class will be divided into groups and each will be assigned to one station. The time will be measured which is needed to assemble one Output by the work of "7 operators". To automate a material flow a parallel I/O communication network will be installed. Finally the whole installation is networked by means of plugs, sockets and cables. 4 input/4 output bits at each station are used to program the handshake procedures. Obviously only one operator is needed to start the assembly task. To add a convenient information flow the wired I/O network will be replaced by a PROFIBUS DP network. The installation work is reduced dramatically but the projecting task is on the other hand more complex. The information flow needs a data design and also the procedure of the handshake should be taken correctly. Concerning Productivity the factor Time will be measured also with this configuration.
