  1. 31. A Mobile Agent Based Service Architecture for Internet Telephony

    Författare :Roch H. Glitho; KTH; []
    Nyckelord :service architecture; mobile agent; SIP; H.323; IN; software upgrading; partitioning; multiparty event scheduling;

    Sammanfattning : Internet Telephony defined as real time voice or multimediacommunications over packet switched networks dates back to theearly days of the Internet. ARPA's Network SecureCommunications project had implemented, as early as December1973, an infrastructure for local and transnet real time voicecommunication. Two main sets of standards have emerged: H. LÄS MER

    Sammanfattning : Många självklarheter i vårt digitala samhälle är beroende av Internet för att fungera. Allt från smarta dörrar för hemtjänster, till självscanningsapparaterna på ICA, till nyare bilar, moderna tillverkningsrobotar, telefoner och affärssystem. LÄS MER

  4. 33. Multihop Wireless Networks with Advanced Antenna Systems : An Alternative for Rural Communication

    Författare :Marvin Sánchez Garache; Jens Zander; Martha Steenstrup; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multihop Wirless Networks; Advanced Antenna Systems; Multiple Access Protocols; Spatial TDMA; CSMA CA; link-scheduling; power control; variable transmission rate; Telecommunication; Telekommunikation;

    Sammanfattning : Providing access to telecommunication services in rural areas is of paramount importance for the development of any country. Since the cost is the main inhibiting factor, any technical solution for access in sparsely populated rural areas has to be reliable, efficient, and deployable at low-cost. LÄS MER

  5. 34. Architecture Support and Scalability Analysis of Memory Consistency Models in Network-on-Chip based Systems

    Författare :Abdul Naeem; Axel Jantsch; Zhonghai Lu; Jari Nurmi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory consistency; Protected release consistency; Distributed shared memory; Network-on-Chip; Scalability;

    Sammanfattning : The shared memory systems should support parallelization at the computation (multi-core), communication (Network-on-Chip, NoC) and memory architecture levels to exploit the potential performance benefits. These parallel systems supporting shared memory abstraction both in the general purpose and application specific domains are confronting the critical issue of memory consistency. LÄS MER
