This appendix describes the client/server and secure connectivity relationships used among the different applications of the Cisco PGW 2200 Softswitch, Cisco BAMS, and Cisco HSI.

Client/Server and Secure Connectivity Relationships

The following figures show the client/server and secure connectivity relationships used among the different applications of the Cisco PGW 2200 Softswitch, Cisco BAMS, and Cisco HSI.

In a network containing Cisco PGW 2200 Softswitch platforms and Cisco BAMS platforms, the Cisco PGW 2200 Softswitch platform is considered to be a server system to Cisco BAMS. The Cisco BAMS platform is a client of the Cisco PGW 2200 Softswitch platform. This means that in the current, non-secure interface environment, to transfer files from the Cisco PGW 2200 Softswitch to Cisco BAMS, the Cisco BAMS system invokes the FTP program which talks to an FTP daemon process on the Cisco PGW 2200 Softswitch platform.

The following table explains the letters and acronyms used in these figures:

Acronym/ Abbreviation	Description
C	Client
S	Server
SCP	Secure Copy
SFTP	Secure File Transfer
SSH	Secure Shell

Secure Connectivity Among Cisco PGW 2200 Softswitch Applications

Figure B-1 illustrates the client/server relationship and the secure connectivity used among the different application types of the Cisco PGW 2200 Softswitch and its network management elements. Note that Cisco VSPT has SSH and SFTP interfaces to Cisco HSI.

---

Note For simplicity, redundant platforms are not shown in this figure. The secure connectivity among the different application types and the redundant platforms is the same.
