whitepaper Blue Lane corrects the traffic directed at a known vulnerability, providing the benefits of patching immediately after a vendor patch is released and without the need to hastily test or install server software patches.
[19 May 2008]
whitepaper The challenge was to consolidate monitoring of the group's logistics and commercial operations and improve control of information flows and integrate data from different sources to reduce network traffic and to make detailed business analysis...

whitepaper DynaMP has a resource discovery mechanism, it distributes code and data using Java classloading, with a caching mechanism to reduce network traffic. Using an ad-hoc network with on-demand routing based on AODV.
[16 May 2008]
whitepaper This paper presents the novel idea of route normalization by correcting on the fly routing traffic on behalf of a local router to protect the local network from malicious and misconfigured routing updates.
[15 May 2008]
whitepaper The network incorporates wireless technology with enhanced security and ATM technology that allows greater bandwidth, to help Pennsylvania Turnpike better manage and monitor roadways and more efficiently move traffic along the toll road.
[15 May 2008]
whitepaper To police network traffic, firewalls must be configured with a set of filtering rules. The existence of errors in this set is very likely to degrade the network security policy. The management of these configuration errors is a serious and complex...

whitepaper Security concerns about HTTP/S traffic are greater in the corporate data center than on the open Web. Dedicated secure sockets layer and other security devices are often needed in this part of the network.
[15 May 2008]
whitepaper This paper describes a traffic-aware optimization framework to improve the operational cost of firewalls. Based on this framework, a set of tools are designed that inspect and analyze both multidimensional firewall rules and traffic logs and...

whitepaper Analysis is performed by careful study of Skype network traffic. This paper analyzes key Skype functions such as login, NAT and firewall traversal, call establishment, media transfer, codecs, and conferencing under three different network setups.
[14 May 2008]
whitepaper These critical devices filter traffic by comparing arriving packets to a list of rules, or security policy, in a sequential manner. Unfortunately packet filtering in this fashion can result in significant traffic delays, which is problematic for...

[11 May 2008]
whitepaper Current packet filtering techniques exploit the characteristics of the filtering policies, but they do not consider the traffic behavior in optimizing their search data structures. Packet filtering plays a critical role in many of the current high...

whitepaper However, most of the related works use deterministic techniques and do not exploit the traffic characteristics in their optimization schemes. It also presents a new packet filtering optimization technique that uses adaptive statistical search trees...
[11 May 2008]
whitepaper Generating random traffic to test the functionality of firewall matching is inefficient and inaccurate as it requires an exponential number of test cases for a reasonable coverage. This paper presents a framework for automatic testing of the...
