The solution is located in both branch offices and the main site when there is mix of
patterns addressed in the cases above. In this situation, a combination of engines and
modules is typically used.
Application Visibility
Q.
How does the Cisco APA Network Module solution identify and detect network
applications?
A.
By performing deep packet inspection on network traffic, the solution is able to quickly identify
protocols and applications. The APA Solution fully reconstructs individual traffic flows and the
Layer 7 state of each individual application flow. Using Layer 7 signatures and attributes in
addition to behavioral classification algorithms, the APA Solution readily identifies applications
that employ dynamically assigned port numbers and tracks applications that involve multiple
interrelated or spanned flows commonly found in voice over IP (VOIP) or multimedia
streaming protocols.
Q.
What business applications and protocols does the Cisco APA Solution support?
A.
The Cisco APA Solution supports about 1000 protocols, including:
●
Business applications: Oracle, Citrix, SAP, Microsoft Exchange, Microsoft SQL
●
P2P: KaZaA, Gnutella, Winny, Win/MX, eDonkey, BiTorrent, DirectConnect
●
Multimedia applications: Real Time Streaming Protocol (RTSP), Session Initiation
Protocol (SIP), Skype, H323, and Media Gateway Control Protocol (MGCP)
●
HTTP (HyperText Transfer Protocol), Network News Transfer Protocol (NTTP), Simple
Mail Transfer Protocol (SMTP), POP3, Internet Mail Access Protocol (IMAP), and so on
●
HTTP classification based on URL or user-agent regular expression
●
RTSP classification based on URL or user-agent regular expression
●
SIP classification based on source or destination domain name
Q.
What is the plan for adding new protocol support on APA Network Module?
A.
Protocols will be updated every two or three months in the form of a protocol pack, which will
be downloaded from Cisco.com and distributed to operating modules and engines. Reporting
Q.
What types of reports are provided by the APA module solution?
A.
The APADC management application is responsible for report generation and provides close
to 200 reports, using about 100 reporting templates. APADC includes report groups that are
used to generate report instances.
There are two main categories of reports:
●
Monitoring reports: Show how network resources are used for selected services at
various granularities (global, user). Monitoring reports typically show a specific metric
for a set of services at a selected granularity, such as bandwidth for P2P and browsing
services at a link granularity, or volume for the streaming services for specific users.
●
Traffic discovery reports: Provide statistical information about network activity and
help identify the characteristics of the traffic traversing the network, such as the top IP
or P2P protocols in the network
