Research adds ITclarity wireless, secure networking tracks!
Tolly Research has added two new tracks to its ITclarity research
program, one focusing on Wireless Ethernet and the other on Secure
Both new research tracks will deliver hands-on performance
testing data, architectural insights and deployment advice. The
Wireless Ethernet track will focus on LAN and internetwork wireless
issues. The Secure Networking track will venture into the impact of
VPNs, firewalls and other security-related technologies on network
tests uncover server backup drain on thin-client performance!
Researchers have discovered that hot backups clearly drain server
CPU reserves and impede application delivery in thin-client sessions
supported on the same server!
results, in Volume 2 of Tolly Research’s ITclarity
Thin-Client Networking track, show that server backups may slow
thin-client applications by up to 24%.

Research focuses on role of traffic shapers in VoIP!
IP telephony research track this month will explore the impact of
traffic shapers on optimizing VoIP services in enterprise networks!
will examine the degree that traffic can be optimized on a converged
network without impacting voice quality. Specifically, Tolly
Research wishes to determine the impact that traffic shaping has on
bandwidth utilization, voice quality and latency - particularly when
traditional network traffic is permitted to burst into bandwidth
allocated for packet voice.

confirm ‘TCP offload’ eases Win2K server load!
Research reports in a recent issue of its ITclarity Windows 2000
Networking track that a representative TCP-offload NIC adapter
successfully diverted TCP bulk file-transfer operations from a
Windows 2000 server, resulting in significant server CPU utilization
did reveal one caveat – that the representative Alacritech 100
Series Dual-Port Server Adapter did not handle all TCP-based
application traffic with the same level of efficiency.
