Overview of Network Traffic Flow

Packets traverse a path when they flow into or out of a system. On a granular level, packets are received and transmitted through receive (Rx) rings and transmit (Tx) rings of a NIC. From these rings, received packets are passed up the network stack for further processing while outbound packets are sent to the network.

Chapter 19, Managing Network Resources introduces the concept of network lanes. A combination of system resources that are allocated to manage network traffic constitutes a network lane. Thus, network lanes are customized paths for specific types of network traffic. Each lane can be either a hardware lane or a software lane. In addition, each lane type can be either a receive lane or a transmit lane. The distinction between hardware and software lanes is based on a NIC's ability to support ring allocation. For more information about ring allocation, see Transmit and Receive Rings. This chapter focuses primarily on incoming traffic that is received through receive lanes.

On hardware lanes, rings are dedicated to the packets that use those lanes. In contrast, rings on software lanes are shared among datalinks. Datalinks are configured to share rings for the following reasons:

Consider the following figure that shows different hardware lanes:
