Behavior of TCP-Like Elastic Traffic at a Buffered Bottleneck Router
White Papers The essential behavior of TCP-like flow-control mechanisms is captured in the analytic model by the feature that the packet-rate of active connections can be throttled in order to avoid that the overall packet-stream exceeds the output-bandwidth...

Behavior of SQL Server 2000 Network Library During Dynamic Port Detection
White Papers This paper discusses the behavior of the SQL Server 2000 network libraries as related to dynamic port detection. The SQL Server 2000 Books Online documentation describes many of the enhancements to the network libraries.

Using Steady-State TCP Behavior for Proactive Queue Management
White Papers This paper describes and evaluates the use of steady-state TCP behavior knowledge for Proactive Queue Management (PQM). It shows how routers can use flow parameters and the knowledge of TCP end-host behavior to intelligently mark packets to prevent...

Use Network Behavior Analysis for Better Visibility Into Security and Operations Events
White Papers Network behavior analysis (NBA) systems analyze network traffic, with data gathered from sources such as Cisco Systems' NetFlow and Juniper's cFlow or sources that support the sFlow standard. Fundamentally, they are a window into the behavior of a...

The Confessions Survey: Office Workers Reveal Everyday Behavior That Places Sensitive Information at Risk
White Papers It is not enough to establish policy; actual insider behavior must be measured and tracked against established policy in order to keep security aligned with the business and in turn, to minimize information risk and maximize reward.
