services such as credit card validation and mapping services. (Note: this
function only works in NAT mode).
•
Built-in Firewall Protections.
Stop possible hacker intrusion into your
network from Internet. All IP addresses and ports are blocked except the
farm IP address. Built-in functions will detect any possible denial of service
attack and make your services always available. (Note: this function only
works in NAT mode with “Forwarding Deny”, see setup for details).
•
In-Path or Out-of-Path Load Balancing.
In normal setup, the WebMux™
can be configured In-Path, to act as firewall in addition to the load balancer
and health checker. However, if outbound traffic is much larger than
inbound traffic and you already have a firewall in place, or change of IP
address causes problems, consider using Out-of-Path configuration. Out-
of-Path load balancing is also called direct routing, or one leg operation.
•
Layer 7 Load Balancing.
WebMux™ can direct traffic to specific groups
of servers within a farm according to a match pattern in HTTP MIME
header. This allows you, for example, to group servers that serve only a
specific type of content while serving other types of content on another
group of servers. WebMux™ Layer 7 load balancing also includes URI
load directing with host name MIME header matching and cookies in order
to memorize the user browser session and the server session and send the
same user to the same server. This is important for sites using shopping
cart and dynamically generated pages.
•
Informs you of the status of your network
. It provides phone pager
and email notification so that the network administrator can be paged or
emailed whenever a server or WebMux™ goes down, and when it returns
online. This feature could reduce server room night shift operator costs, or
timely repair should the server goes down unexpectedly.
