Chelsio delivers traffic management and filtering


SUNNYVALE, CA – June 29, 2009 - Chelsio Communications, Inc., the leading provider of 10-Gigabit Ethernet (10GbE) adapters and ASIC solutions, today announced it has delivered complete traffic management (TM) and filtering capabilities for its T3-based Unified Wire Adapters, enabling the efficient management of offloaded traffic and filtering of received packets for a wide range of virtualized application environments.

Chelsio’s Unified Wire adapters are now able to shape and pace offloaded TCP traffic per connection or per arbitrary class and filter non-off-loaded (tunneled) received packets at 10Gb rate on the fly.   The TM and filtering functions can be mixed and matched in a wide variety of applications, including storage virtualization, where traffic to each storage disk head must be regulated.  Other applications include firewalls, LFN, and video/IPTV, in which video servers must be able to present predictable latency and bandwidth.

“The traffic management and filtering at 10Gb solves a wide range of application problems for our customers,” said Kianoosh Naghshineh, president and CEO of Chelsio Communications.  “Combining different traffic profiles onto a converged fabric is a requirement for virtualized environments, making traffic shaping essential for a wide range of applications.”

Both the traffic management and filtering can be mixed and matched, dependent on the application requirements.  TM and filtering are both available today as a licensable option on top of the Chelsio S-series adapters.
