1 Data Sheet V-Net Link 700 C Series Link Load Balancer V-NetLink:Link Load Balancing Solution from VIAEDGE

2 V-NetLink : Link Load Balancer As the use of the Internet to deliver organizations applications increases, maintaining only one link to the public network exposes a single point of failure and serious network vulnerability. V-NetLink seamlessly monitors availability and performance of multiple AN ISP connections to intelligently manage bidirectional traffic flows, providing fault tolerant and optimized Internet access. V- NetLink delivers improved link performance and high availability with the added benefits of flexible and powerful health checking, comprehensive security, and improved usability. Key Advantages: Eliminates deployment barriers and dramatically reduces the costs of multihoming via Border Gateway Protocol (BGP). Maximizes ROI for connectivity aggregating inexpensive links. by Ensures traffic is directed over the best possible link and ISP for the highest quality of service and speed Dramatically improves WAN performance with TCP/IP optimizations link Even traffic distribution overburden any connection. that doesn't Bandwidth Aggregation all links appear as single fat pipe Reduced connectivity cost by intelligently managing around high-priced traffic spikes. Reliable Network Connectivity High Availability V-NetLink ensure maximum uptime of the link balancing system through high availability and failover. When used in high availability mode, a first V-NetLink is designated as the active or master unit and the secondary the passive or slave unit. Both units constantly communicate information and metrics, should the active unit stop responding the passive unit takes over traffic management and continues operations normally while alerting the IT department of a troubled unit. Traffic Segmentation V-NetLink can direct traffic from and to services on links specified by the organization s policies to provide optimal traffic management and cost management. An example of this feature in production would be to assign symmetrical links to applications which benefit them such as VPNs and keep asymmetrical traffic on asymmetrical links such as ADSL and cable modems for lower priority traffic such as web surfing.

3 Maximum Bandwidth and ROI Quality of Service V-NetLink QoS feature enables organizations to proactively manage bandwidth allocated to services and applications, to ensure that key elements such as , VoIP and VPN have the required bandwidth and that less desirable traffic does not capture critical throughput. Traffic priorization and classification is a key element to ensure quality of service. The Quality of Service module enables organizations to control available bandwidth based on customer policies for ports, protocols and applications. LAN Failsafe V-NetLink is a failsafe device, ensuring that bandwidth is available at all times and manage the failover process. But what if the Link Balancer itself should lose power? V-NetLink Layer-2 approach enables the installation of Link Balancers without any modification to the existing network, permitting the V-NetLink device to relay traffic between the primary link and the Traffic Distribution: Round Robin Global Availability Packet Completion Rate Least Connection Packet rates Packet Completion rate User Defined QoS Dynamic Ratio Random network perimeter devices (firewall, HSIA gateway, etc.). User Defined QoS Server Verification Intelligent Server Verification can perform two types of tests to verify a server or service s availability, a Layer-7 (L7) exchange or a Layer-4 (L4) connection. The L4 tests will attempt to connect to the defined service on the specified TCP port and if the connection is successful the service is considered to be available. The L7 test will replicate a real user request for a web page (for example), get the result from a web server and locate a keyword in the returned page to confirm that everything is in order.

4 Configuration & Management Cost reduction using low-cost ISPs ca in not only enhance the over Internet experience and uptime, but also reduce overall costs. Here is an example commonly used: Existing bandwidth configuration: 2X T1 circuits at $600/month providing Mbps symmetrical Proposed bandwidth: 2X cable modems at 10Mbps/1Mbps - $100/month 1X DSL circuit at 6Mbps/1Mbps - $80/month Total throughput: 26Mbps/ 3Mbps (compared to 3Mbps/3Mbps) Monthly savings: $600/month or $7200/yearly Incoming Balancing V-NetLink can adjust automatically its configuration based on time-based conditions. Through this feature, bandwidth can be allocated to optimize operations in contexts such as: * Allocating bandwidth to subnetworks based on corporate priorities * Toggle specific actions or change of configuration * Cost-based utilisation based on time conditions to reduce costs related to burstable links or links with transfer limits * Freeing bandwidth not used in non-peak business schedules fore core activities such as site to site data replication and backup * Distributing available bandwidth between different networks sharing a common infrastructure. Eliminates Barriers of Multi-homing with BGP V-NetLink eliminates the deployment barriers and reduces the cost of multihoming via Border Gateway Protocol (BGP). You can direct traffic over the best route without purchasing larger routers, coordinating with ISPs, or obtaining specialized staff and IP addressing to run BGP. V-NetLink improves traffic direction for multi-homed environments by providing: Bi-directional traffic control for both external and internal users Traffic routing down the best path to optimize bandwidth usage Traffic distribution based on line capacity, resulting in greater bandwidth scalability Simple, Secure Administration V-NetLink provides an intuitive user interface to manage WAN links from a single point with comprehensive visibility into link resources. Security Edge Network Security V-NetLink is a default-deny device that resists common attacks by adding an additional layer of security. Uses secure remote administration based on Secure Shell (SSH) for command line or SSL for browser-based management Reaps idle connections to thwart denial of service attacks Performs source route tracing to thwart IP spoofing Resists unacknowledged SYN without ACK buffers to thwart SYN floods Protects itself and servers from ICMP attack
