Page 7: Chapter 1 Introduction
The 9E312-12 is a thirteen port switching module with twelve front panel Ethernet interfaces and one Internal Network Bus (INB) backplane interface. This module uses a Fast Packet Switch (FPS) hardware based switch design and an advanced ® Intel i960 microprocessor. -
Page 8: Features
Spanning Tree, RMON, and MIB support within a scalable RISC-based architecture. Fast Packet Switching The 9E312-12 incorporates a hardware based switch design referred to as a Fast Packet Switch (FPS), a collection of custom ASICs designed specifically for high speed switching. Because all frame translation, address lookups, and forwarding decisions are performed in hardware, the 9E312-12 can obtain a throughput performance of greater than 130K pps. -

INB, the INB NIB reassembles the data blocks received from the INB back into canonical frames for transmission to the Fast Packet Switch (FPS) and ultimately to the front panel port. The INB can time slice its bandwidth using one of three methods. - Page 10 Introduction ETHERNET 9E312-12 MMAC PLUS MMAC PLUS Figure 1-1. The 9E312-12 Module...

Page 19: Chapter 3 Operation
As shown in Figure 3-1, Ethernet Network Interface Blocks (ENIBs) convert data packets received from any front panel port into a canonical frame format before forwarding to the Fast Packet Switch (FPS), while the Internal Network Bus Network Interface Block (INB NIB) converts data packets received from the INB into a canonical format before forwarding to the (FPS). -

Ethernet data packets for transmission out front panel ports. Fast Packet Switch The Fast Packet Switch (FPS) is a hardware based switch design that is the key building block of the MMAC-Plus. All filtering/forwarding decisions are made in hardware as opposed to software as in traditional bridges. This custom hardware allows the FPS to process over 150K frames per second. -

Operation and control the SMB LANVIEW diagnostic LEDs. Although the system diagnostic controller and the main host processor can operate independently of each other if needed, they exchange information about each others status and overall module condition. The information gathered by the diagnostic controller is available to the network manager via local/remote management and the LCD located on the environment module. -
