Throughput

With the capacity requirements of telecom

networks ever increasing, there are two trends to

allow higher system throughput: (1) Offloading

the communications processing from the host to

the NIC, and (2) the transition from PCI to PCI

Express. Offloading the communications

processing, such as compression and decoding,

from the system host allows the system to

operate with more efficiency and hence

increased traffic capacity. Because of its performance scalability and

protocol advances, PCIe-based systems are faster and more reliable

than their PCI-based counterparts.

These transitions are complicated in the fact that a processor on the

line card will tend to be enumerated by the system host. This processor

needs to be isolated from the host to prevent this. In addition, most

communications processors on the market today are PCI-native. So

there are two problems to solve: isolating the line card’s processor and

bridging it from PCI to PCI-Express.

Offload Network Processing from the Host

The solution is found in a single device from PLX:

The PEX 8114 PCI Express to PCI-X ExpressLane

bridge. This device bridges the PCI (or PCI-X) bus on

the network processor to PCI Express for enhanced

bandwidth. This is the only PCI Express Bridge to feature Non-

Transparent mode.
