Recently, HOB succesfully tested the operation of 100,000 concurrent RDP sessions with the highly performant and Common Criteria EAL 4+ certified HOB WebSecureProxy (= WSP). The WSP is part of the highly secure and comprehensive SSL Remote Access Suite HOB RD VPN.
Description Of The Test Arrangement: Test makes use of 3 machines (equal hardware – Power edge R930 – list price: 91.327€ per Server). Operating system on all machines: Linux - Ubuntu 14.04.3 LTS 64-bit).
The WSP has 2 network adapters in separate networks. The other 2 machines are connected to the WSP via 10Gbit Ethernet.
To setup 100.000 sessions via WSP, test tools xbttcp95 & xbttcp23 were used. xbbttcp95 establishes an SSL connection to WSP and sends test data which are forwarded to the test server xbttcp23. The amount of data sent in every connection are typical for an RDP connection. Each instance of xbttc95/23 made 500 connections (so 200 instances of each tool are started). For load-balancing reasons, 100 instances of both tools are started on both machines called „Server/Client“.
After all 100.000 sessions are running, network thruput is measeured on WSP machine using nload is meassured. Additional „real“ RDP connection is set up using JWT 3.3 to a Windows 2012R2 terminal server to get an subjective impression of performance.
100.000 were setup successfully and running for several hours. Network thruput was 3.3 Gbit/s. Using real RDP connection it was possible to login and work on terminal server in an acceptable manner.
Cipher suite used in test AES256_SHA256. There was no significant difference of the thruput when AES-NI was enabled or disabled.
At an increasing rate, today’s enterprises are being driven to lower operational costs and improve employee productivity. Between the continual rise of fuel prices and the way the economy has been affecting people, telecommuting is starting to become a trend that companies are drawn to. The concept of a virtual workplace, or telecommuting, has increasingly been implemented as a way to boost employee satisfaction and productivity as well as reduce their carbon footprint and energy expenses, in an effort to be more environmentally friendly.
Companies are ‘going green’ by using environmentally-friendly and resource-sparing applications of information technology. In most cases, telecommuters are reducing their companies’ carbon footprint by shifting energy consumption to their own homes. Secure remote access solutions utilizing SSL (Secure Sockets Layer) offer access to individual PCs, whether at the company office, home or on the road. In addition to providing employees with the flexibility to work inside and outside of business hours, remote access offers significant energy savings.
As virtual workplace programs grow in popularity within enterprises, there continues to be no shortage of studies and surveys indicating its bright future. In a analyst report by Forrester Research it is predicted that the U.S. telecommuting ranks will swell from 34 million in 2009 to 63 million by 2016 -- fueled by broadband adoption, better collaboration tools and growing management experience.
With remote access solutions at the backbone of virtual workplaces, employees are always connected to their corporate networks while visiting customers, business partners, at home or while in the field. The ability to securely, economically and reliably access enterprise resources from diverse platforms and terminals is, now and in the future, a not-to-be underestimated competitive advantage.
