20 Claims

1. A network system comprising a plurality of interconnected network nodes, the network system comprising:

a) a plurality of network switches, distributed within the network, wherein each of the plurality of network switches configured for interconnecting network nodes in the network and for forwarding data link frames;

b) the plurality of network switches comprising at least a first network switch at a first node interconnecting a second network node and a third network node in the network;

c) the first network switch using PCI Express transactions for communicating to a PCI Express root bridge in the second network node connected to it, wherein the first network switch behaves like a PCI Express end node; and

d) the first network switch is configured to implement a method for communication between the second network node and the third network node, the method comprising:

i) receiving a first address of a first data link frame;

ii) using the first address of the first data link frame for reading the first data link frame;

iii) receiving the first data link frame in a first PCI Express memory read completion; and

iv) writing the first data link frame to memory in the third network node.
