Traditional processing application and control function not only may be implemented in processor module, can also realize intelligent and efficient packet processing,
IP forwarding performance is substantially improved.
QoS (Quality of Service), i.e. service quality, for network service, service quality include transmission bandwidth,
Transfer delay, data packetloss rate etc..It in a network can be by guaranteeing the bandwidth of transmission, the time delay for reducing transmission, reducing data
Packet loss and reduce the measures such as delay variation to improve service quality.And Internet resources are always limited, simply by the presence of robbing
The case where taking Internet resources by force just will appear the requirement of service quality, therefore, network manager need according to various businesses the characteristics of
Internet resources are reasonably planned and distributed, so that Internet resources be made efficiently to be utilized.
QoS in current DPDK is a kind of model by different level, includes port (port), subport (subport), pipe
(pipeline), traffic class (traffic classes) and five layers of node of queue (queue), as shown in Figure 1, the first of hierarchical structure
Layer is Ethernet TX port 1/10/40GbE, and subsequent stratum level is defined as subport, pipeline, traffic classes and queue, often
A subport represents one group of predefined user, and one user of each pipeline representative, each traffic classes be have it is specific
Loss Rate, delay and jitter require the expression of the different flow type of (such as voice, video or data transmission).Each queue
Carrying belongs to the data packet of same type of one or more connections of same user.DPDK primary specification of a model
Subport represents user group, and pipe represents single user, does not illustrate to the correspondence of equipment, causes how family and family to be arranged
The QoS service of front yard equipment does not implement.
