Introducing the Contivity Extranet Switch
To restrict access, the Switch uses packet filtering based on Protocol ID,
Direction, Source and Destination IP addresses, Source and Destination Ports,
and TCP connection establishment.
The unique quality of service (QoS) mechanisms include call admission
and packet forwarding priorities, and support for Resource ReSerVation
Protocol (RSVP).
The HTML and Java Web management interface allows different Switch
administrators to have different access rights, including configuration, status, and
monitoring. The Switch offers RADIUS accounting support and extensive
logging, including events, system, configuration, and security logs.
Figure 1-2 shows a front view of the Switch.
