VIRTUAL PRIVATE NETWORKS (VPN) ARE NO MATCH FOR BEAM’S POINT-TO-POINT (P2P) TELEPHONE: 800-918-7189 | EMAIL: [email protected] | WEBSITE: BeamMe.com About OneMedNet | Founded in 2009, OneMedNet set forward on a journey to create safer and more intelligent care solutions for patients, providers & hospitals. The company has been solely focused on creating solutions that simplify digital medical image management, exchange and sharing. VPN’s have widespread usage across many applications and sectors. In simplest terms, a VPN stretches a private network NETWORK MANAGEMENT COSTS across a public network for data exchange. By doing so, it offers improved security when compared to solely using the public internet. However, for the purposes of clinical image exchange there are a number of disadvantages to relying on a VPN for DICOM image sharing. The BEAM P2P image sharing solution takes a different and far better approach. BEAM leverages SSL (Secure Sockets Layer) which is the standard security technology for ensuring an encrypted link between a web server and browser. SSL is used by millions of websites to protect online transactions. VPNs require a significant amount of human and financial resources to setup and maintain. Here are several of the resource challenges: 1. Network equipment (e.g. firewalls, routers, switches – if needed) must be purchased, installed, configured, and maintained. 2. VPN security keys must be agreed upon, managed, and regularly rotated. 3. Network address conflicts must be resolved via complex arrangements such as NAT’ting over VPN 4. When one side makes a network change, it can render the VPN unusable and require both sides to engage and fix it. BEAM eliminates the need for all of this setup and on-going maintenance by elegantly handling all traffic routing and configuration automatically. Here’s a high level comparison of the two image sharing approaches across five important categories. Those include: Security, Network Management Costs, Scalability, Speed, and PACS/Modality Configuration. PACS AND MODALITY CONFIGURATION With a VPN, the PACS or modality must be told the AE title and IP of each destination in addition to all of the aforementioned VPN/network maintenance. SECURITY SPEED A VPN is analogous to an airplane jetway (show graphic somewhere). The path is fairly secure from outside interferences but the traceability of who (or what) is going through the pipe is minimal. Furthermore, the pipe is secured only by the two ends (or firewalls). If there is a breach at one end, it opens a clear path to the other end (or organization). Transmitting DICOM over a VPN is only 70% efficient for In the specific case of image sharing, even if it’s secured down to only the DICOM ports, DICOM query retrieve has no security (or auditing) to track what is sent or requested across DICOM. an example, latency from Hawaii to L.A. is 156 ms. Obviously, BEAM’S CONNECTIONS ON THE OTHER HAND • Are individually secured by SSL technology used in the banking industry • Are formed instantaneously only as needed for a given transfer • Dissolve immediately upon transfer completion thereby avoiding the open VPN tunnel risk any given network bandwidth. VPNs are very handshake intensive. As latency increases (with for example increasing distance), transfer speed of a VPN declines significantly. As time is critical for strokes, traumas, and tele-radiology cases with short SLAs. Additionally, under DICOM over VPN, transfers can be interrupted and irrecoverable if a sufficient network glitch (lost packets) occurs. The last part of a study or an entire series could be lost in transmission. SCALABILITY VPNs are individually established between two points. Thus, to set up N sites with complete enterprise connectivity requires many connections (N² - N). As an example, in the case of connecting five (5) sites with VPNs, this would require 20 connections. The setup and maintenance requirements for each node and VPN tunnel are not insignificant. Whereas, BEAM allows a site to get on and connect with anyone with no additional setup. BEAM ALLOWS YOUR ORGANIZATION TO CONNECT AND SCALE TO AN INFINITE NUMBER OF SITES. Whereas, BEAM is infinitely and easily scalable with no additional PACS configuration required. BEAM IS MUCH FASTER AND EFFICIENT (2X-3X) • BEAM routing is dynamic. No costly dedicated pipes are required and routing can “go around” down internet segments. • BEAM is stateless. Network connectivity interruption does not affect BEAM. BEAM will deliver the entire data set bit-perfect to the destination. • BEAM will resume transmission after packet loss ceases or network connectivity is restored. • BEAM is highly tolerant of slow connections. BEAM can even run over a cellular or satellite connection.
