Radware (NASDAQ: RDWR), the leading provider of intelligent integrated solutions for ensuring the fast, reliable and secure delivery of networked and Web-enabled applications over IP, today announced that its LinkProof® 1000 multi-WAN switch, maintained 100% of Voice over IP (VoIP) calls in a simulated primary WAN outage by instantly and automatically switching calls to a secondary WAN link. The test results verify Radware's proven capability to keep critical voice and data traffic running fast and securely, across multiple branch offices, even during ISP failures, natural disasters, or any other condition that would otherwise halt business operations.
In a simulated headquarters multi-WAN link to a remote branch environment, Miercom installed two LinkProof 1000s simulating connections with two different telecom carriers so that LinkProof's failover, intelligent re-routing and load balancing capabilities could be rigorously tested. Miercom also evaluated the LinkProof APSolute Insite management console's ability to set and modify policies for network and VoIP traffic protocols from anywhere in the network.
Miercom's findings underscored LinkProof's abilities to keep critical headquarters-to-branch connectivity of applications and data up and running at all times, specifically in the areas of VoIP Resiliency, Bandwidth Optimization, Health Monitoring and Security. Radware's IPS has five signature modules that include: Intrusions, DoS/DDoS, SYN Floods, Anomalies, and Anti-scanning. Radware's anomaly protection module is used to scan packets to check for deviations with all RFC standards.
With respect to VoIP Resiliency, Miercom concluded that LinkProof is a very compelling option for enterprise customers that require 100% up time and reliability from VoIP and data networks. In tests involving a group of 100 simultaneous VoIP calls from the headquarters site through a primary WAN IP route, LinkProof maintained all connections without any disruptions. And by managing LinkProof using the Insite management console, Miercom was able to power LinkProof from any of its systems anywhere in the network, coupling a simplified user experience with the ability to keep VoIP calls connected.
Miercom used LinkProof's out-of-the-box definitions for hundreds of well known services to create very granular Bandwidth Optimization policies to evaluate LinkProof's ability to maintain a high quality of VoIP calls. Miercom concluded that LinkProof was able to sufficiently optimize bandwidth across branch offices so that VoIP calls maintained the highest quality while still allowing other critical application traffic to flow over the network.
Miercom also evaluated LinkProof's ability to perform health checks on network links and to maintain high levels of security. Miercom test engineers were able to create up to 19 different types of checks using LinkProof's Health Monitoring Module. The engineers found that all of its network traffic deemed "high priority" was consistently routed onto the healthiest WAN link available. Testing the separately licensed Intrusion Prevent System (IPS) module, the test engineers also had the opportunity to review the different functions and capabilities of the IPS.
Miercom's Final Conclusions on LinkProof
Based on rigorous testing of LinkProof and a review of its configuration, deployment and operation, Miercom found that:
- In VoIP traffic tests of 100 concurrent calls, LinkProof maintained 100% of VoIP connections when a simulated WAN outage automatically switched calls to a secondary WAN link
- LinkProof is able to automatically reroute current VoIP calls using preset thresholds to maintain the highest quality available
- LinkProof provides bandwidth optimization and load balancing for VoIP data traffic
- LinkProof features a large assortment of settable and tailorable QoS policies for health monitoring of VoIP and data traffic
- LinkProof includes Intrusion Prevention System capabilities for Intrusions, DoS attacks, etc.
Radware's approach, which is based on proprietary Radware technology, gives maximum visibility into both latency and the path of network traffic, ensuring network managers combine the power of link load balancing with granular bandwidth management for control of application performance across multiple links.
"We're very pleased that the results of this independent test verified what we've known all along about the critical site-to-site connectivity role that LinkProof plays in our APSolute suite of integrated application delivery products," said Paul Fiore, senior director, partner programs, Radware. "We engineered LinkProof to be the primary multi-wan switch needed for health monitoring, load balancing and bandwidth optimization. With LinkProof, enterprise customers can ensure the reliability, efficiency, cost-effectiveness, and security of their VoIP deployments by augmenting traditional POTS failover features, appropriately routing high-priority traffic, eliminating call self-termination due to latency or jitter, and providing protection against DoS and other attacks."
Test Methodology
The Miercom test consisted of two simulated sites: a headquarters and a remote branch site, connected by a primary IP WAN link and a load balancing or secondary link. The network infrastructure at both sites consisted of Extreme Networks Summit48 L2/L3 switch/routers, a LinkProof 1000 switch, a WinSIP and a WINH323 VoIP traffic generator.
A group of 100 G-711 ULAW simulated VoIP calls were generated and maintained from the headquarters side by Touchstone Technologies WinSIP ver. 2.4.8 and a WinH323 ver. 1.4.4 VoIP traffic generator through the LinkProof to the remote branch for two minutes, then continually re-established for a total of two hours each.
After verifying all of the VoIP session was established, a standard ping test was initiated to the primary link on the remote LinkProof. The primary IP link was physically removed from the LinkProof and the loss of connection was verified by the ping test. For consistency, all SIP and H323 calls from the headquarters had to traverse the LinkProof 1000s primary gigabit IP links and terminate to the WinSIP and WinH323 generators at the remote branch site. This was verified by an IP address using the command line interface on the LinkProof 1000.
