Q11: Using a USB Flash Drive to Deploy the Huawei AR G3 is Said to Improve the Efficiency of Network Deployment and Maintenance. Is This True?What Are the Application Scenarios?
A: In the enterprise network industry, a large number of enterprise-class access routers are deployed in branches of operation and maintenance centers that are sited far away from each other. Software commissioning and maintenance in these cases are very costly. As a result, the access routers must be able to provide cost-effective delivery and remote maintenance. To solve this problem, the Huawei AR G3 supports plug-and-play with USB flash drives to facilitate commissioning-free deployment. This enables engineers to perform software configuration and commissioning without going to the actual site. Project deployment using a USB flash drive can be divided into two scenarios: Device upgrade: Deployment using a USB flash drive automatically installs the upgrade, configuration, license, patch, voice, and https files. Deployment on a production line: Deployment (primarily of new routers) using a USB flash drive on the production line involves only system software packages. This method deletes any rollback records and startup packages and clears the usage records of the router. In this way, this deployment mode fits in the routers that just leave the factory.
Q12: What Are the Architecture and Functions of the OSP?
A: As one of the key components of the Huawei AR G3, the OSP consists of hardware, an operating system,and application programming interfaces(APIs). The OSP was developed to cater for the various requirements of global enterprise customers as they rapidly increased. Using the platform,enterprise users can develop and install service software features on demand. In this way, OSP helps Huawei and enterprise users achieve a win-win scenario together in multiple fields, such as voice application servers, WAN accelerators, IPS, IDS, and AV.
Q13: What Does the Full Name of the Huawei AR G3 Series Routers Mean?
A: The Huawei AR G3 series enterprise-class access routers are named using the following format:”AR” + “Number” + “Letter 1” + “-” + “Letter 2”.Take the names of AR1220,AR1220W/VW,and AR2240-A/D for example, “Number” indicates the model and “Letter” is the supplementary description of the model.Letter 1: E indicates enhanced, V indicates voice, and W indicates Wi-Fi.Letter 2: P indicates PoE and S indicates resale model. Although names of the AR1220V/1220W/1220VW/1220W-S do not contain the suffix P, these models also support PoE power.
