Our link load balancing capabilities allows for
Internet sessions to be balanced across multiple WAN links which
enables faster connectivity for end-users and increases the
overall bandwidth available to the network. Link balancing has
advantages in that it does not utilize as many system resources
and allows for dynamic route manipulation in order to optimize
WAN utilization.
Enterprise Class Link Redundancy
The Edge Wan & Internet Load Balancer delivers a solid yet
flexible solution for organizations looking for a reliable network
load balancing product. Our applied patent technology was developed
to ensure multilink stability and reliability while running
on our high performance platforms.
Instant Server Connection Resiliency
The EdgeXOS appliance incorporates our own ActiveDNS technology
which is essentailly a built-in dynamic DNS server (no external
service is required). The ActiveDNS module works in a way which
ensures instant failover from one inbound server link to another
(i.e. not wait for a TTL to expire). This capability is typically
not found in most competing products, and is certainly not available
in most "firewall" multi-wan solutions.
Link Selection Policies
The EdgeXOS appliance includes the ability to create ordered
policies for routing inbound and outbound traffic based on the
status of each WAN link. This way network administrators can
determine how traffic is routed, and under what circumstances,
in the event an outage occurs on any of the ISP links. This
"ordered" application of rules provides administrators with
a great degree of flexibility when configuring failover policies.
Session Persistence
The EdgeXOS appliance has built-in enhanced session policy-routing
which ensures that applications which are sensitive to link
hopping maintain their state throughout the session. Network
administrators can also create policies for specific destination
networks to allow either more relaxed or stricter session enforcement
based on the organizations unique requirements.
Without The EdgeXOS
There are a number of other products on the market, typically
"firewall" products which say they also offer link balancing
and redundancy. The reality that most of these products lack
a number of critical features that are required to deliver a
true solution, including:
Built-In DNS Intelligence
Most "firewall" solutions do not incorporate internal DNS and
rely on external "dynamic DNS" providers. The problem with this
approach is that not only is it more expensive, as the end-user
must then purchases a service contract with the external DNS
provider, but that with this method there is no way to instantly
update the DNS queries on the fly. While these other solutions
can send an update to the external DNS provider, there is no
guarantee that the update will take immediately and even once
it does, external clients must wait for the TTL to expire.
Session Persistence Capabilities
Most "firewall" solutions which include link balancing capabilities
do not perform well when used with applications which require
session persistence. Much of the time users will find that applications
only work some of the time while other applications stop working
in the middle of a file upload, etc. The EdgeXOS appliance is
an enterprise class solution which does not suffer from these
issues.
True Link Bonding
Unlike most other "firewall" solutions which include some form
of limited link failover and/or balancing, none of those solutions
offer the ability to
bond WAN links for improved web-based downloads by utilizing
ALL of the active ISP connections at the same time. This is
one of the more unique capabilities of the EdgeXOS appliance
and one that provides a significant advantage over other solutions
in the market today.
