Linux support boosts
packet processing blade
Force Computers has added support for the Linux operating system to its CHAMP server blade with AltiVec technology
Force Computers has added support for the Linux operating system to its Common Heterogeneous Architecture for Multi-Processing (CHAMP) server blade with AltiVec (AV) technology. Using Linux 2.4.18, this quad G4 CompactPCI blade provides five Motorola PowerPC processors to meet the intense data processing/throughput demands of 'high-touch' packet applications.

Italtel to apply central office platform
Italtel will base its next-generation iMSS media servers, media gateway servers and signalling servers on Force's new Centellis CO 31KX AdvancedTCA modular communications platform
With four MPC7410s performing packet analysis and one MPC8240 managing onboard data flow, CompactCHAMP-AV provides 4096 H.110 channels of time-division multiplexing (TDM) switching along with meeting packet-processing requirements.
Upgrading to a Compact CHAMP/Linux solution using Force's full-feature Linux support package provides total control over all blade hardware aspects as well as reducing total cost of ownership compared to legacy circuit-based telecom switches by up to ten times.
With Linux available on the Compact CHAMP architecture, Force Computers offers one of the most cost-effective multi-processing solutions on the market.
By dedicating the MPC8240 I/O processor to control the onboard data flow, the four MPC7410s are freed to concentrate solely on packet analysis.
For high-touch packet applications, the 4096 channels on the H.110 interface can be routed to all available onboard resources so all the G4s can perform packet analysis.

Specifically, telecom circuit-based switch applications can benefit by upgrading to Compact CHAMP-with potential total cost of ownership savings of up to 10 times versus legacy technologies.
The Compact CHAMP-AV's four PowerPC G4 500MHz processors are divided into two symmetric multiprocessing SMP nodes, each operating as a dual MPC7410 processor SMP Linux system.
In addition, each SMP node has: 4Mbyte L2 cache; 256Mbyte of dedicated local SDRAM; a tightly coupled PCI mezzanine (PMC) slot; and a PICMG 2.16-compliant Ethernet interface.
As the OS manages memory sharing and the Ethernet interfaces, the SMP node architecture seamlessly distributes multi-threaded applications across all the processors.
This enables focus on customer applications and not inter-processor communication.
As an example, for a high-touch packet application such as packet inspection, the local memory of the SMP pairs would receive offboard packets from the H.110 bus, process them according to a high-touch packet algorithm, then retransmit the packets offboard.
Offboard transmission is either conducted through the onboard PICMG 2.16 Ethernet interfaces or via specialised I/O cards populating the associated PMC slots, which can support eight Ethernet interfaces or other interfaces equal to a total data rate of OC3.
Performance is further enhanced by Force's Linux support package with its optimisation of data flow.
