The OpenScript Engine

The OpenScript engine provides the ability for direct interaction with traffic passing through a

ServerIron ADX. User-provided, custom logic written in the Perl programming language can use

ServerIron ADX monitoring capabilities to observe network traffic between clients and servers and

then react to traffic patterns by altering the traffic flows. Figure 1 illustrates the flow of traffic

through an OpenScript engine residing on a ServerIron ADX. As traffic moves between clients and

servers, the OpenScript engine can respond to changing traffic patterns and shape traffic flows as

required.

FIGURE 1 The OpenScript Engine

As shown in Figure 1, the OpenScript engine can host user-provided custom Perl scripts that use

protocol events APIs and Data inspection APIs to determine traffic conditions and then call data

manipulation APIs to change traffic flows.

Capabilities provided by the Brocade OpenScript engine

Using the capabilities of the Brocade OpenScript engine, you can enhance the operation of the

ServerIron ADX to provide the following:

• Future-proof your infrastructure by transforming ServerIron ADX functionality without changing

hardware or software.

• Facilitate rapid delivery of new services to end users

• Fix broken applications

• Monitor traffic with custom statistics and send it to data collectors

• Deliver legacy applications that are not supported on the ServerIron ADX natively

• Temporarily mitigate security attacks through rapid script development
