  • design and implementation of a user level sockets layer over virtual interface architecture
    Concurrency and Computation: Practice and Experience, 2003
    Co-Authors: Sungin Jung, Soonhoi Ha
    Abstract:

    SUMMARY The Virtual Interface Architecture (VIA) is an industrystandard user-level communication architecture for system area networks. The VIA provides a protected, directly-accessible interface to a network hardware, removing the operating system from the critical communication path. In this paper, we design and implement a user-level Sockets layer over VIA, named SOVIA (Sockets Over VIA). Our objective is to use the SOVIA layer to accelerate the existing Sockets-based applications with a reasonable effort and to provide a portable and high-performance communication library based on VIA to application developers. SOVIA realizes comparable performance to native VIA, showing a minimum one-way latency of 10.5 µs and a peak bandwidth of 814 Mbps on Giganet’s cLAN. We have shown the functional compatibility with the existing Sockets API by porting File Transfer Protocol (FTP) and Remote Procedure Call (RPC) applications over the SOVIA layer. Compared to the Giganet’s LAN Emulation (LANE) driver which emulates TCP/IP inside the kernel, SOVIA easily doubles the File Transfer bandwidth in FTP and reduces the latency of calling an empty remote procedure by 77% in RPC applications.

    Co-Authors: Januar Al Amien, Doni Winarso
    Abstract:

    Cloud computing merupakan teknologi yang menjawab tantangan akan kebutuhan teknologi komputasi yang efisien. Terdapat banyak hal yang dapat diimplementasikan menggunakan teknologi cloud computing seperti web service, layanan penyimpanan, aplikasi dan lain-lain. Penerapan cloud computing dengan menggunakan teknologi container dapat membantu dalam pengelolaan aplikasi serta mengoptimalkan penggunaan sumber daya berupa penggunaan memory dan prosesor pada server. Dalam penelitian ini penerapan docker container diimplementasikan menggunakan layanan aplikasi FTP (File Transfer Protocol). Layanan  FTP dibuat menjadi 3 container didalam satu computer server. Untuk menangani permasalahan beban kinerja pada FTP server terhadap permintaan yang terlalu berat (overload) digunakan load balancing. Load balancing merupakan metode untuk meningkatkan kinerja sekaligus mengurangi beban kinerja pada FTP server. Berdasarkan hasil pengujian, penerapan multi container serta load balancing didalam FTP server dalam penanganan beban memiliki hasil penggunaan memory yang lebih kecil dan pemanfaatan penggunaan prosesor yang merata

    Abstract:

    Abstract Cloud computing is a technology that answers the challenge of the need for efficient computing technology. There are many things that can be implemented using cloud computing technologies such as web services, storage services, applications and others. Use of cloud computing using container technology can help in the management of applications and optimize the use of resources in the form of memory and processor usage on the server. In this research docker containers implemented by service of FTP (File Transfer Protocol). The FTP service is made into 3 containers within a single server computer. To handle load problems performance on the FTP server against overload requests, load balancing is used. Load balancing is a method to improve performance while reducing the performance load on FTP servers. Based on the test results, the use of multi container and load balancing in the FTP server in load with two algorithm least connection and raound robin handling has result of smaller memory usage and utilization of processor usage evenly. Both algorithms are recommended for handling loads for FTP servers and will be more efficient when applied to servers with the same specifications and loads Keywords: Cloud Computing, Docker, FTP, Load Balancing, HAProxy, Least Connection, Round Robin.

  • ftp ndn File Transfer Protocol based on re encryption for named data network supporting nondesignated receivers
    IEEE Systems Journal, 2018
    Co-Authors: Ite Chen, Chenkai Cheng, Jhengjia Huang, Wentsuen Chen
    Abstract:

    Due to users’ network flow requirement and usage amount nowadays, TCP/IP networks may face various problems. For one, users of video services may access simultaneously the same content, which leads to the host incurring extra costs. Second, although nearby nodes may have the File that a user wants to access, the user cannot directly verify the File itself. This issue will lead the user to connect to a remote host rather than the nearby nodes and causes the network traffic to greatly increase. Therefore, the named data network (NDN), which is based on data itself, was brought about to deal with the aforementioned problems. In NDN, all users can access a File from the nearby nodes, and they can directly verify the File themselves rather than the specific host who holds the File. However, NDN still has no complete standard and secure File Transfer Protocol to support the ciphertext transmission and the problem of the unknown potential receivers. The straightforward solution is that a sender uses the receiver's public key to encrypt a File before she/he sends the File to NDN nodes. However, it will limit the behavior of users and incur significant storage costs of NDN nodes. This paper presents a complete secure File Transfer Protocol, which combines the data re-encryption, satisfies the requirement of secure ciphertext transmission, solves the problem of the unknown potential receivers, and saves the significant storage costs of NDN nodes. The proposed Protocol is the first one that achieves data confidentiality and solves the problem of the unknown potential receivers in NDN. Finally, we also provide formal security models and proofs for the proposed FTP-NDN.

  • parallelized File Transfer Protocol p ftp
    Local Computer Networks, 2003
    Co-Authors: Shaleeza Sohail, Sanjay Jha, H Elgindy
    Abstract:

    Parallelized FTP (P-FTP) approach, attempts to solve the problem of slow downloads of large multimedia Files while optimizing the utilization of mirror servers. The approach presented in this paper downloads a single File from multiple mirror servers simultaneously, where each mirror server Transfers a portion of the File. P-FTP server calculates the optimum division of the File for efficient Transfer. The dynamic monitoring ability of P-FTP maintains the File Transfer process at the optimized level no matter how abruptly network and mirror server characteristics change.
