VMS Web Services Installation & Configuration
Services Overview
The Comtech EF Data–Vipersat Network Products Group VMS Web Services
SOAP (Simple Object Access Protocol) Server offering provides an interface
for two VMS client applications and communications with the VMS (RPC
server):
• VNO (Virtual Network Operator) – Allows satellite network operators to
selectively extend network operation functions to individual customers for
monitoring and controlling their own network(s).
• ArrangeLink (AL) – A satellite communications Circuit Scheduler
interface allowing customers to schedule network resources for
applications such as video conferencing and scheduled broadcasting.
The SOAP interface runs on a web services proxy server that hosts the web
applications for VNO and AL using Internet Information Services (IIS). The
user interface for these applications is accessed using a web browser from a
client PC workstation.
The network component diagram shown in figure 2-47 reflects the recom-
mended configuration for implementing the VMS Web Services. To minimize
latency issues, the host platform for these services should be on the same LAN
as the VMS Server. Should a network web server be locally available, it would
serve as a logical platform for the SOAP server, as shown in the diagram.
Figure 2-47 VMS Web Services Components
If there is no local web server available to host these services, then the follow-
ing alternative configurations can be utilized:
• If the VMS is stand-alone, then the VMS Server can host the Web
services and applications.
• If the VMS is redundant, then another local server must host the Web
services and applications in order to retain true redundancy.
* Note: the Web Client PC can be local or remote
