Article link to title Technology link to title New network performance optimization technology – BIG TCP | Oilbeater’s self-study room The existing GRO and TSO can hand over the work of packet splitting and assembly to the network card, and the kernel processes data according to 64k package, which can bring about a 10x performance boost. Mainstream NIC drivers only support TCP Offload. What [[BIG TCP]] needs to do is to make the data packet processed in the kernel bigger. The main limitation of the data packet processed by the kernel before is that the size of the 64K packet is that there is a length field in the header of the IP packet. The length of this field It is 16bit, so theoretically the maximum length of an IP packet is 64K. In IPv6, the packet length is obtained through hop-by-hop, and in IPv4, the actual packet length is calculated directly from the kernel’s skb->len.
Why is DNS still hard to learn?
Why [[DNS]] is difficult to learn, DNS problems in daily work are very headaches, plus the domestic characteristic network, it is even more troublesome.
Breaking: AWS Begins Charging For Public IPv4 Addresses – Last Week in AWS Blog
After [[Azure]] and [[GCP]], [[AWS]] started charging for [[IPv4]] addresses. Some time ago, my [[bandwagonhost ]] VPS was renewed. The reason for the renewal was that I couldn’t find a cheaper [[IPv4]] address in the market.
