VNO Install
VNO Overview
Comtech EF Data - Vipersat Network Products Group VNO solution provides
an interface into a defined subset of the actual network managed by VMS. This
is exposed as a Web Services SOAP interface provided by the VNO-WS.exe
service. The VNO web service supports both non-redundant stand-alone and
redundant VMS deployments.
With redundant VMS servers, figure 2-50 depicts the VNO-WS.exe installed on
a separate Windows workstation running the same service providing active
awareness between the VMS Servers. It is recommended that this separate
workstation be the same workstation running ViperView (Client PC worksta-
tion).
The VNO-WS service accepts requests from the VNO Web application running
on an IIS server. Requests and responses transmitted between the web applica-
tion on the IIS server and VNO-WS web service uses SOAP over HTTP proto-
col. The SOAP request is translated into an RPC call into VOS and the response
is returned to the web application, which usually transforms into HTML and
sends the HTML back to a web browser where a VNO user interface is
presented to the VNO user.
The Viperview client communicates directly with VOS using DCOM/RPC
protocols. Viperview is used by the Central Network Operator for administra-
tive functions, such as creating VNO networks, and other resources in the
network. Refer to the VNO User Guide for details.
