1. L3 Forwarding with Access Control Sample Application

http://dpdk.org/doc/guides/sample_app_ug/l3_forward_access_ctrl.html

Source Code

http://dpdk.org/doc/api/examples_2l3fwd-acl_2main_8c-example.html

librte_net.c >> rte_ip.h

http://dpdk.org/doc/api/rte__ip_8h_source.html

line93 >> struct ipv4_hdr

line96>> unit16_t total_length

line102>> unit32_t src_addr

2. DPDK Latency

3. 順利產生C program Call Graph >> Source Code要自行編譯

若太大不能產生圖或報錯.

4.複習C語言, 我真的有學過嗎?

netdev_run()

初始化(ovs thread >> R/W lock / MUTEX互斥鎖 LINK, vport初始化)

netdev_registered_class

netdev_class (控制netdev, 針對虛擬dpdk, 實體NIC都有不同的netdev_class)

cmp_node

ovs_refcount

netdev_dpdk()

allocate

mbufs (memory buffer)

mempool (放在hugepage內)

QoS (QoS Type如何處理等等)

rte_eth / rte_vhost

NIC Driver allocate RX Buffer

dpdk_eth_dev_init

定義RX / TX Queue 的number 跟 size
