Load Balancing and
Failover Using BGP
For an automated approach to load balancing
and failover, NetVanta routers can share bandwidth
between ISPs using Border Gateway Protocol (BGP).
With BGP, “best route” routing decisions are made
automatically between ISPs. In the event that one
connection is lost, the NetVanta router switches traffic
over to the remaining ISP in service. This maximizes
bandwidth usage and provides a high-speed disaster
recovery scheme, if needed. In addition, for a safe
and controlled Internet surfing experience, NetVanta
routers integrate with Websense, a leading provider
in Web content filtering.
High-Speed Ethernet Service
The NetVanta 3430 is a perfect platform to meet the
high-performance needs of a high-speed Ethernet
service. With its revolutionary RapidRoute technology
to interpret session traffic, the performance-injected
NetVanta 3430 delivers faster processing cycles and
rapid routing decisions. Even with processor-intensive
services enabled, like NAT, Firewall, and VPN, the
NetVanta 3430 with RapidRoute outperforms the
competition and can accommodate larger-
bandwidth applications.
