The appliance offers a number of unique and interesting features that may increase your networks efficiency and productivity dramatically.
Main Product Features
Outbound Load-Balancing
With real-time load balancing and Optimum Route algorithmic, AscenLink's intelligent router engine directs each session or connection to the best available link. It also supports policy-based routing, persistent routing, and traffic scheduling to effectively translate your business policy into your network policy. AscenLink supports non-NAT mode to support Intranet traffic load balancing for either private leased lines, or MPLS-based VPN.
Fault tolerance
The network health check engine monitors the network around the clock and provides fail-over/fail-back functions.
- Failover: Whenever a link fails or is unstable, traffic is automatically re-routed to other healthy and available links to ensure uninterrupted connectivity.
- Failback: When the faulty link resumes functioning,on-line traffic is redistributed across all available connections to optimize the networks performance.
Inbound Load-Balancing
When external users request the Web server's IP address, SwiftDNS dynamically returns DNS responses according to the link quality and load-balances incoming traffic across the different ISP lines.
Multihoming
Health check and SwiftDNS guarantee uninterrupted availability through dynamic DNS reconfiguration, which ensures that a response with a valid IP address is returned to an external user's request for a web server's IP address. AscenLink's Multi-homing system supports both built-in DNS or DNS relay to your existing DNS server.
High Availability
AscenLink supports a active/passive deployment for a timely contingency backup in case of hardware failure. In the case of a hardware failure in the active unit, the passive unit will take over immediately to ensure continuous function. AscenLink also supports port-level HA to enable all the switches connected to AscenLink be dual-deployed for complete HA deployment for the entire network topology.
Highly available networks
Enterprises have become dependant on networking services. Therefore, reliable network performance is crucial today for an organization's longterm success. AscenLink helps you build efficient, stable high performance networks at very low costs.
Tunnel Routing
Tunnel Routing constitutes one of AscenLink's outstanding features. It provides link aggregation and fault tolerance over multiple ISP lines. Traditional IP sec VPN establishes a secure tunnel over just one single link; AscenLink, however, can do so over multiple links. Tunnel Routing is essential for establishing reliable high-performance networking infrastructures based on VPN. It may also be beneficial in demanding applications such as video streaming etc.
Server High-Availability
AscenLink allows traffic load balancing for multiple servers and therefore reduces the risk of service failure. You will be able to offer uninterrupted services to your customers and partners.
Bandwidth Management
AscenLink manages bandwidth according to the categories service, traffic source and traffic destination. For each category, the user can set maximum and minimum bandwidth. As a result, mission-critical applications will always have a guaraneed bandwidth.
