Santa Clara, CA - April 23, 2002 - UTS Global, LLC announces commercial grade support for the Cisco 7500 Series Router on Linux/390 (Linux on the mainframe). The commercial grade CLAW driver supports both CLAW packing protocol and CLAW protocol.

The CLAW (Common Link Access to Workstation) channel protocol is used to transport data between the mainframe and the Cisco Channel Interface Processor (CIP) for TCP/IP environments.

CLAW packing is a Cisco proprietary enhancement to the CLAW protocol which enables the transport of multiple IP packets in a single channel operation. Substantial TCP/IP throughput improvement has been demonstrated.

The UTS Global Enhanced CLAW driver transparently supports both PACKED and TCPIP (normal CLAW) interfaces. The driver first attempts a PACKED connection with the Cisco router, but will automatically attempt connection using the normal (TCPIP) CLAW protocol if the PACKED connection fails.

Minor router configuration changes are required to enable the CLAW packing feature once the appropriate changes to the mainframe Linux kernel (CLAW driver) and host configurations are implemented.

UTS Global has previously released a Cisco CLAW driver for Linux/390 under the UTS Global Public License.

The latter product will continue to be available for non-commercial usage, pursuant to the terms and conditions of the UTS Global Public License.
