EdgeMarc Series Benefits
The EdgeMarc Series converged network appliances offer reduced costs , increased security, guaranteed call quality, simplified management and VoIP survivability when delivering advanced IP services to enterprise customers.
Reduced Costs
Edgewater's EdgeMarc appliances provide up to 90% reduction in total cost of ownership (TCO) over competing solutions over a 3 year period. The graph below illustrates the savings provided for a typical VoIP deployment using T1 WAN link with up to 10 concurrent calls and 50 VoIP subscribers.
THIS REPRESENTS A SAVINGS OF $267 PER SUBSCRIBER AND A TOTAL SAVINGS OF OVER $40,000,000 AT 150,000 SUBSCRIBERS.
Additionally, EdgeMarc appliances often pay for themselves in the initial installation by reducing on-site time required to deploy the hosted PBX service.
Increased Security That Resolves VoIP NAT/Firewall Traversal Issues
Concern about the overall security of IP-based voice services is often cited as a principal issue that limits the adoption of these services by the enterprise. Indeed, securing VoIP transmissions with traditional firewalls is a daunting task as VoIP signaling protocols require public IP addresses and utilize dynamic TCP/UDP ports that sometimes originate from outside of the firewalls. These requirements expose enterprise customers to unnecessary risks as their LAN topology is easily discovered and traditional firewalls using coarse-grained enforcement policies are easily defeated. Additionally traditional firewalls that perform NAT for data traffic do not support the NAT operations required by VoIP protocols when using private IP addressing. This incompatibility complicates VoIP deployments.
Edgewater EdgeMarc Series network appliances deliver comprehensive security for the enterprise through a powerful combination of network and VoIP security technologies. Each appliance includes a state-of-the-art VoIP-aware firewall and NAT server to hide private IP addresses. The firewall couples knowledge of VoIP signaling with traditional packet filtering to dynamically open and close ports and ensure that only authorized traffic reaches the protected LAN. It is equally proficient in handling non-VoIP data traffic and can either augment or replace legacy enterprise firewalls. At the same time, the included NAT server effectively hides the topology of the enterprise LAN protecting it from many attacks including Denial of Service failures, Trojans, Nimda, Code Red, Buffer Overflows and over 1,000 common attack signatures for continuous protection against hackers. Finally, the integrity of the EdgeMarc Series appliances themselves are protected through the use of authenticated SSH tunnels for secure remote management. This ensures that the system is not subverted through unauthorized administrative access.
Guaranteed Call Quality
Edgewater EdgeMarc Series appliances provide sophisticated yet easy to use QoS mechanisms to ensure the reliability of mission critical voice and data traffic. These mechanisms are configured through flexible user-defined policies and include traffic shaping, priority queuing and DiffServ packet marking. They protect voice and data traffic from contending for the same network resources to guarantee low latency and the highest call quality possible. At the same time they ensure the best utilization of WAN bandwidth by enabling voice or data traffic to burst up to full line rate when possible. In addition Edgewater provides Call Admission Control (CAC) to protect voice traffic from being negatively affected by other voice traffic. CAC uses a deterministic algorithm to decide when there are insufficient network resources available to adequately support new calls and then return the equivalent of a “fast busy” to new call requests.Without an EdgeMarc Series appliance users experience voice clipping, echo and dropped calls. Deploying an EdgeMarc Series appliance results in toll quality calls for every active call and prevents new calls from negatively impacting voice quality.
Simplified Management - Easy To Deploy, Easy To Manage, Easy To Scale
Edgewater EdgeMarc Series appliances are purpose built for remote installation at customer premise locations. As a result they provide several features that enable the service provider to easily deliver high quality, responsive service to enterprise customers:
• A secure, easy to use and understand browser-based Graphical User Interface (GUI) that enables the service provider to configure, upgrade and manage the appliance remotely.
• Edgewater products provide passive MOS scoring, alarms for minimum MOS measurements and raw data for post-processing analysis such as jitter, latency, packet loss, etc.
• DHCP, TFTP and FTP support to enable the dynamic configuration of many VoIP phones and IADs.
• Integrated packet capture and utilization of well known IP troubleshooting tools.
• Comprehensive interface and system utilization statistics.
Finally, integrating multiple functions usually provided by several standalone systems into a single appliance reduces management complexity and better positions the service provider for rapid growth.EdgeMarc Series appliances provide survivability features that enhance reliability and availability of hosted VoIP service offerings. Deployed at the customer premises they provide local station to station call switching in the event of WAN link failures, softswitch failures or during periods of network congestion that result in loss of connectivity to the softswitch. They also support redundant softswitch applications. For additional information please download the VoIP survivability application note.
EdgeProtect Series Benefits
The EdgeProtect Series session border controllers use a scalable architecture to provide comprehensive security, simplified operations and breakthrough price/performance for managed VoIP service providers.
EdgeProtect Series products provide topology hiding for VoIP operations infrastructure. Network and port address translation is used for service provider peering applications and to ensure that network-based hackers are not able to discover the real IP addresses of mission critical VoIP network elements. A stateful packet inspection firewall is combined with a VoIP application layer gateway for voice and data. Data port scans and many types of DOS attacks are blocked by the filtering available in the EdgeProtect 6400.
EdgeProtect Series products provide NAT/Firewall traversal to extend the reach of VoIP services. They automatically detect when a VoIP subscriber is behind a NAT/FW device and perform the packet translations required to connect the subscriber to the hosted service. This is useful in instances where VoIP-aware application layer gateways are not installed at the CPE.
EdgeProtect Series products us an adaptive shortest path RTP architecture that eliminates hairpinning. They will forward media that does not require NAT/FW traversal services using the shortest IP path between VoIP endpoints. This increases scalability and minimizes the effects of jitter and latency on voice calls.
They also provide an easier way to manage mobile VoIP subscribers and subscribers with frequent IP address changes (such as xDSL users) using a Dynamic Access Control List (DACL). DACL is used to identify and authenticate VoIP subscribers as they register with the hosted service. This authentication mechanism eliminates the need to manually program IP addresses of valid subscribers in other firewalls around the perimeter of the data center. This also enables the service provider to easily support mobile VoIP subscribers that perform frequent IP addressing changes.
Finally, EdgeProtect Series products perform passive call quality monitoring for trend analysis and real-time troubleshooting of VoIP performance problems.
Breakthrough Price/Performance
Based on industry standard hardware the EdgeProtect Series does not require a large upfront capital investment and the systems can be clustered for additional scalability and redundancy.
EdgeConnect 2402PoE Benefits
Ideally suited to today's converged networking environment the EdgeConnect 2402PoE provides advanced remote administration, traffic management for prioritization, integrated power management and greater realibility.
Advanced Remote Administration
Reduce the need for onsite service calls or administration with the many remote management tools provided by the 2402PoE. These include port mirroring for advanced diagnostics, SNMP, http, Telnet and more.QoS and VLANs To Ensure High Quality Voice and Video
The EdgeConnect 2402PoE prioritizes voice and video traffic over data using per port or 802.1Q tagged VLANs. The 2402PoE also supports traffic classification by 802.1p, IP precedence/TOS, DSCP or TCP/UDP number.Integrated Power Management
