SSL VPN system depends on TUN device on Linux host. Without TUN device, it can't be deployed on Linux hosts. In order to overcome this limitation, a new kind of SSL VPN system is developed. This system is based on simulated virtual NIC based on loopback interface. With the help of simulated virtual NIC, SSL VPN client can be deployed on Linux hosts without TUN devices. Thus a Linux host without TUN...
The normal file operations (read, write, and so on) do not make sense when applied to network interfaces, so it is not possible to apply the UNIX “everything is a file” approach to them. Thus, network interfaces exist in their own namespace and export a different set of operations. With the widely application of network in Linux platform, In this paper, the design of network device driver for RTL8139C...
To facilitate the use of the NoC techniques an efficient design of the network interface (NI) unit that connects the switched network to the IP cores is required. In this paper, we present a new pipelined NI architecture for NoC. We introduce a new distributed buffer structure that increases area and reduces latency and jitter. The low latency and minimal jitter between packets are obtained through...
We propose a novel method to export both interface control and data planes across different hosts, effectively enabling hardware specific control of network interfaces over the Internet, or from a host to its virtualized guests. Our solution is a major step towards distributed environments of heterogeneous communication systems, particularly relevant in the scope of custom system composition, remote...
Amongst link technologies, InfiniBand has gained wide acceptance in the framework of High Performance Com puting (HPC), due to its high bandwidth and in particular to its low latency. Since InfiniBand is very flexible, supporting several kinds of messages, it is suitable, in principle, not only for HPC, but also for the data acquisition systems of High Energy Physics (HEP) Experiments. In order to...
Financial transaction systems, such as those utilizing the Financial Information Exchange (FIX) protocol, must make buy/sell decisions based on information received over a network interface. However, at the time that a decision to buy or sell is made, some data on the system may not yet be visible to the financial engine software because it has not yet completed being processing by the network protocol...
Virtual network is an important approach to support multiple legacy applications running unmodified in distributed virtual computing environments. A virtual networking approach called VirNet is proposed in this paper. VirNet can build multiple customized and isolated virtual networks simultaneously on the same physical hosts in the network, and it enables existing distributed applications written...
This article gives you a detailed guide for the construction of a Diskless HPC Cluster using Fedora as Operative System. The final purpose of the Cluster is to run both RAMS (Regional Atmospheric Modelling System) and CAMx (Comprehensive Air quality Model with extensions) Numerical Models in a Parallel and/or Grid manner. Themes ranging from CPU Architecture Selection, passing by Operative System...
Zero-copy has been a hot research topic for a long history, which is an underlying technology to support many applications, including multimedia retrieval, datamining, efficient data transferring, and so on. Zero-copy means during message transmission, there is no data copy among memory segments on any network node. When a message is sent out, the data packets in user application space go through...
With significant advances in network interfaces, I/O bus, and processor architecture of end node, innovative approaches are required to achieve high network bandwidth by fully utilizing available system resources. The issues related can be summarized into two: (i) Utilizing I/O bus bandwidth for high bandwidth network connection and (ii) Utilizing multiple cores for high packet processing throughput...
