peer to peer (P2P). Once this traffic has been identified, the network administrator is able to
appropriately configure quality of service (QoS) policies to control the traffic so that the time-
critical and high-priority portion of LAN-WAN traffic will not suffer from giving up the bandwidth
to the less critical applications. The result is overall reduction of network congestion, improved
application performance, and the ability to plan more effective network bandwidth upgrades.
Q.
What product components make up the Cisco APA module solution?
A.
The Cisco APA module solution consists of the following components:
●
APA Network Module, which is responsible for traffic classification using deep packet
inspection of the traffic and providing application/protocol and user awareness as well
as collecting the reporting data (NME-APA-E2 or NME-APA-E3).
●
The APA Device Console management application. APADC is responsible for
management of APA Network Modules individually or as a group.
●
The operating system software resident on the module (APA-SW-1.0 or APA-SW-2.0).
Note that APA Device Console and the OS are included as one image.
●
A view-only or control software license.
Q.
What type of customers can benefit from deploying the Cisco APA module solution?
A.
Cisco APA Network Module is targeted for distributed enterprise customers that have several
remote locations and branch offices and that are attempting to classify and prioritize
application traffic. Cisco APA Network Module controls the behavior of the network traffic over
the WAN links to make sure that the performance of each individual application reflects its
importance to business operations.
Managed service providers can also use the Cisco APA Network Module solution to their
advantage and further enhance their competitive differentiation. Service providers can offer
managed Cisco APA services alongside their existing managed router and managed security
business and take advantage of the existing infrastructure and processes. It strengthens
service providers' value proposition by allowing them to focus on application performance
instead of simply offering connections. The managed Cisco APA service provides all the
benefits of Cisco APA Solution without the initial costs of obtaining and installing the
equipment and the costs of ongoing management, allowing the organization to focus on its
core business.
Q.
How is the Cisco APA Solution deployed?
A.
Deployment scenarios are differentiated by the location of the traffic management solution.
Possible deployment scenarios include:
●
The solution can be located in the branch offices, an arrangement that facilitates
efficient traffic prioritization and bandwidth management of the traffic triggered by the
branch office, such as most of the TCP-based applications and multimedia User
Datagram Protocol (UDP) traffic. In this deployment scenario, APA Network Module is
typically used.
●
The solution can be located in the main (headend) site, for example, when there is a
significant amount of streaming traffic initiated from the main site and the customer is
interested in protecting the WAN links. In this deployment scenario, either the APA
Engine (larger head offices) or APA Network Module (smaller head office) can be used.
