“…To compare these two technologies we've set a virtual laboratory with virtual machines acting as clients, routers with NAT and servers. The results of this benchmark showed a 15-20% speed advantage of SSTP over OpenVPN, while OpenVPN performed better in packet loss conditions [6]. We should note that Microsoft SSTP is limited to x86 (Intel Architecture 32 bit) and x86-64 (also known as AMD64) Microsoft Windows platforms, although Linux implementation has no such limitation.…”

This paper describes software and hardware solution that enables Global Navigation Satellite System (GNSS) data acquisition with ground based stations network. The solution relies on original data format and relational database management system. C++ library code and database schema SQL-structures are created automatically from Javads Receiver External Interface Specification (GREIS) with a C# application. This solution was used to create a real time ionosphere monitor service based on Feodorov Institute of Applied Geophysics ROSHYDROMET GNSS-receiver network.

“…Pada pengujian perbandingan SSTP & OpenVPN yang dilakukan (Aleshin, I.;Vasiliev, A.;Kholodkov, K.;Perederin, 2015) menghasilkan kesimpulan pada jaringan yan tidak stabil dengan throughput yang rendah, kapasitas SSTP lebih tinggi dibandingkan OpenVPN. (Farly et al, 2017) melakukan implementasi dan pengujian protocol SSTP dan L2TP yang menghasilkan kesimpulan total packet loss pada SSTP terhadap 20 kali percoban pengiriman lebih kecil dibandingkan protocol L2TP.…”

SISTER is a web-based application that runs using Virtual Box. SISTER was first initiated by the Ministry of Research, Technology and Higher Education in 2017 and must be applied by all universities in Indonesia. SISTER is used for university lecturer administration services. In the field conditions, it was found that not all universities have run the SISTER application properly with various technical problems, namely SISTER can only be accessed through the university's private network, so that Lecturers who have high mobility are difficult to access SISTER from public networks or the internet. In order for SISTER to be accessed from the internet, a Public IP is needed which is usually provided by an Internet Service Provider (ISP) or cloud service provider which requires relatively expensive costs. Campus GoPublic provides an alternative for Universities who want to make SISTER that is already running on a private university network, each of which can be accessed via the Internet by connecting via a VPN with the SSTP protocol to the GoPublic Campus VPN Server. To analyze the performance of the SSTP protocol on the KampusGoPublic service used by the Nusantara Jaya Tourism Academy, testing is needed. The method used is an experimental method. The test uses the page load time technique to find the average time required for the host to display the SISTER web server page on a private network. So that the packet on the private server will pass through the SSTP server to be accessed from the public network. Based on the results of the average Page Load Time test, the KampusGoPublic service that uses the SSTP protocol runs well with the fastest page load time of 1.75 seconds in Cache Enable mode and 3.78 in Cache Disable mode so that the SSTP method is considered ideal for bridging data between servers. on a private network and a VPN Server to be connected to a public network.

“…The latter facilitates network deployment greatly because the station needs an IP address to accept connections with and global IPv4 address exhaustion makes assigning an IPv4 address to each station nearly impossible. However this stratagem is not always viable and in case IPv4 address depletion makes trouble there is another solutionutilizing virtual private networks as shown in [Aleshin et al, 2015].…”

Here we describe an integrated software and hardware solution for stationary geomagnetic observations. The solution provides a feature-rich way to perform geomagnetic data acquisition for wide range of use cases, including poor data transfer conditions and power limited environments. Data transfer is implemented with widespread Seedlink protocol, which features small data overhead and automatic recovery of missed fragments. Geophysical application of data acquisition stations often implies installation at sites that are hard-to-reach or are only accessible on non-regular basis. Therefore, our solution includes full-fledged remote control and diagnostics of station equipment via web APIs in addition to standard remote management tools like secure shell. The modular nature of this software also provides flexibility for connecting various hardware. By this moment, we have implemented full support for POS-1 magnetometer; more support for other models is planned. The software is platform independent and has small CPU and memory footprints hence it runs on both low power x86 systems and ARM-based System-on-Chips, which provide great opportunities for further reduction of power consumption.
