    Packet Transactions: High-level Programming for Line-Rate Switches

    Full text link
    Many algorithms for congestion control, scheduling, network measurement, active queue management, security, and load balancing require custom processing of packets as they traverse the data plane of a network switch. To run at line rate, these data-plane algorithms must be in hardware. With today's switch hardware, algorithms cannot be changed, nor new algorithms installed, after a switch has been built. This paper shows how to program data-plane algorithms in a high-level language and compile those programs into low-level microcode that can run on emerging programmable line-rate switching chipsets. The key challenge is that these algorithms create and modify algorithmic state. The key idea to achieve line-rate programmability for stateful algorithms is the notion of a packet transaction : a sequential code block that is atomic and isolated from other such code blocks. We have developed this idea in Domino, a C-like imperative language to express data-plane algorithms. We show with many examples that Domino provides a convenient and natural way to express sophisticated data-plane algorithms, and show that these algorithms can be run at line rate with modest estimated die-area overhead.Comment: 16 page

    The Evolving Service Culture of Cuban Tourism: A Case Study

    Get PDF
    The case examines the impressive growth of tourism in Cuba. It analyzes tourism development in a society striving to navigate its way economically amid numerous social and political challenges. The Cuban experiment with tourism is a shortterm mega success. However, it is highly uncertain whether long-term sustainability can be maintained without the appropriate managerial changes at all levels. This paper highlights challenges in the tourism employment sector – training, supervisory issues, and performance evaluation, within a centrally controlled bureaucratic system. Of specific interest is the disconnection between the natural hospitability of the Cuban people and low levels of tourist satisfaction stemming from a lack of professional hospitality. The paper concludes by focusing on the high relevance of the Cuban cultural identity as a key motivator undergirding the demand for tourism. However, with the rapid growth of tourism, strains are occurring in the cultural realm, thus requiring immediate policy intervention for sustained positive results

    Accuracy of Siriraj stroke scale in the diagnosis of stroke subtypes among stroke patients

    Get PDF
    Background: Early detection of intracranial blood is essential for the rational use of anti hemostatic drugs in stroke patients. CT scan is quite expensive as well as it is not easily available especially in the rural areas. Clinical stroke scores were developed to overcome these limitations. Aim of present study is to identify the stroke subtype using Siriraj stroke scoring and thus asses its accuracy by comparing with CT scan reports.Methods: A cross sectional study was conducted in a tertiary centre that evaluated 464 patients admitted with a diagnosis of stroke. Siriraj Stroke score was calculated for each patient and a CT scan of brain was also taken. The results of diagnosis made by Siriraj stroke scoring were compiled and compared with the diagnosis obtained by CT Scan.Results: Of the total 464 patients, the incidence of hemorrhagic stroke was 27.8% and ischemic stroke was 72.2%, as per the CT scan reports, while the Siriraj stroke score diagnosed 16.8% patients to have hemorrhagic stroke and 74.6% to have ischemic stroke and no definite diagnosis was made in rest of the patients (8.6%). The sensitivity of the scoring was found to be 59.2% in diagnosing hemorrhagic stroke and 95.5% in ischemic stroke.Conclusions: Our study has shown that siriraj stroke scoring has a high degree of accuracy in detecting both types of strokes, with roughly 80% of both hemorrhagic and ischemic strokes being correctly identified. However there is a low sensitivity in diagnosing hemorrhagic strokes and higher sensitivity in diagnosing ischemic strokes
