Organizations of all sizes share an ongoing goal of increasing employee productivity and reducing costs through technology. Your business can cost-effectively meet your office communications and application integration needs by using Cisco® integrated services router platforms to deliver data, voice, security, wireless LAN, switching, and video services on a single, converged network, customized to meet the needs of your business today and in the future.
As organizations continue with the trend toward centralization and consolidation of their branch-office IT footprint, the Cisco integrated services router has been instrumental in integrating the networking infrastructure together and significantly reducing operational costs. The Cisco Application Extension Platform (AXP) provides a powerful and flexible environment to extend this concept. It enables hosting and integration of custom applications and network services into the Cisco integrated services routers. Using the AXP (Figure 1), the integrated services router becomes a powerful integration platform to build and host complete vertical centric solutions.

Cisco AXP developers can fully develop and test their applications using the Cisco AXP Virtual Development Blade. Running on VMWare, the virtual blade fully emulates an AXP blade allowing application developers to build AXP applications from a standard PC running VMWare Player.
Cisco AXP Features
The Cisco AXP provides a Linux-based integration environment to host custom applications and services. The features of the platform include:
• Robust packaging, installation, and upgrade facilities: The complexity of managing software for multiple devices is provided as part of the core platform offering. Cisco AXP provides appliance functions, allowing the application developer to focus on the application and not worry about the underlying infrastructure.
• Multiple application support: Using the virtual instance manager, Cisco AXP supports the ability to host multiple applications or components. These components can be independently installed, upgraded, or removed. The instance manager provides the ability to segment and guarantee resources (CPU, memory, and disk) consumed by each component. In addition to resource controls, the virtual instance manager provides a segmented Linux OS instance on the AXP that is fully controlled by the developer, allowing the developer to use custom libraries and binaries built for different Linux distributions. Developers can utilize standard packages built for a variety of different Linux Distributions.
• Extensible command-line interface (CLI): Cisco AXP allows you to extend the interface of the Cisco module by adding custom CLI commands to administer and monitor an application. By extending the supported Cisco interface, the end user has a consistent and integrated experience.
• Prepackaged value-added components and programming environments: Cisco AXP allows you to use all programming technologies supported by Linux. To ease integration, Cisco provides prepackaged and certified libraries to implement C, Python, Perl, and Java applications.
• Secure hosting infrastructure: The Cisco AXP protects against rogue software by enforcing authorization of all software. Only partners and developers can build applications that run on AXP, helping ensure that all AXP-based solutions are of the highest quality and reliability. The AXP infrastructure also provides a layer of protection between Cisco IOS Software and the AXP application, helping ensure a misbehaving application cannot compromise the security and performance of Cisco IOS Software.
Beyond providing a hosting platform within the router, Cisco AXP provides a robust set of APIs, allowing the application to integrate into the network:
• Packet monitoring API: Applications can monitor selected packets flowing through the network for monitoring and analysis purposes. With Cisco AXP, the need for a dedicated span port and complex wiring is no longer necessary.
• Cisco IOS Software information API: Using this API, an application can programmatically query the router to retrieve current configuration, statistics, routing information, and so on. All information available to the Cisco IOS Software CLI and Simple Network Management Protocol (SNMP) agents are accessible though this interface.
• Event-trigger API: The event-trigger API allows the application to react to changes or events that occur within the router. An application event can be triggered on events such as a router interface failing over, packet loss exceeding a certain threshold, changes to routing-table state, and so on.
• Cisco IOS Software configuration API: The configuration API allows the application to dynamically change the configuration of the router. Used in conjunction with the monitoring, information, and event-trigger APIs, an application can dynamically change the behavior of the router in real time.
• Serial-device API: Cisco AXP provides an application to communicate directly with serial ports of the router, offering the ability for the integrated services router to support connectivity to traditional and nonstandard devices.
The Cisco AXP SDK provides all the tools necessary to package, host, and integrate applications into the router. SDK features include:
• Packaging tools allow the third party to build an installation package. All the complexity of installation, upgrades, dependency management, and recovery is provided as part of the Cisco AXP packaging toolkit:
– The Bundling tool allows developers to create a single image composed of their application, add-on components, and the entire AXP infrastructure. You can install or upgrade to the latest version of the software by downloading a single image.
– Linux software RPM package conversion tools allow the application developer to easily port standard Linux components onto Cisco AXP.
– The Dependency tool helps developers identify missing libraries and executables required by their application.
• A CLI extension API provides all the tools necessary to extend the AXP CLI with custom application commands.
• Header files and source code for the Cisco IOS Software packet, information, event, configuration, and serial APIs offer multiple programming language support, including C/C++, Java, Perl, and shell scripts.
• Example source code illustrates the usage of the APIs.
