摘要： A port adapter for connecting zero or more network interfaces to a host system having a SPI-4 bus is disclosed. The port adapter comprises zero or more network interfaces; a SPI-4 bus coupled to a host system to provide a communication channel between the host and the network interfaces; a control bus coupled to the host system for controlling and monitoring the port adapter; and interface logic that interfaces the SPI-4 bus and the control bus to the network interfaces. Methods are provided for selecting and using one of a small plurality of different packet formats for various networking technologies, so that the port adapter can hide details of the technology that it handles from the host system, and for operating the host system's SPI-4 bus at one of several speeds based on bandwidth requirements of the port adapter.

摘要： In one embodiment, packet memory and resource memory of a memory are independently managed, with regions of packet memory being freed of packets and temporarily made available to resource memory. In one embodiment, packet memory regions are dynamically made available to resource memory so that in-service system upgrade (ISSU) of a packet switching device can be performed without having to statically allocate (as per prior systems) twice the memory space required by resource memory during normal packet processing operations. One embodiment dynamically collects fragments of packet memory stored in packet memory to form a contiguous region of memory that can be used by resource memory in a memory system that is shared between many clients in a routing complex. One embodiment assigns a contiguous region no longer used by packet memory to resource memory, and from resource memory to packet memory, dynamically without packet loss or pause.
