Project Goals

Provide access to internet data
visualization tools via command line or
WWW interface
– http://www.merit.edu/ipma/tools/
Allow people to create their own data
channels
 Controlled access to public and private
data streams

Description
Push-Pull server model allowing data
access from heterogeneous clients
 Supports Historic & Real-Time Queries
 Attribute based data discovery
 Multi-Server capability
 Client-side libraries available in C, C++,
and Java

Features
Configurable (configuration files,
admin tools, logging…)
 Security via IP Access Control Lists
(wildcard allow/deny)
 Multi-Platform Support (UNIX and
Win32)

Multi-server capability
Run a private server to use our publicly
available viz tools on your own data
 Allows shared access to public data
streams
 Configurable peers
 Unicast based with plans for multicast
in the future
