Small Knowledge Points: Socket: An interface between the application layer and the transport layer, one endpoint of the communication. Divided into streaming sockets (providing bidirectional ordered without duplication, no boundary record of the data stream) and datagram Sockets (bidirectional, not guaranteed to be reliable and orderly and without duplication). Port: integer identifier, 16 bit, 0~65535,1024 below is reserved bit, such as 80 is HTTP port, 21 is FTP communication port. 1024~49151

Added the AXI4 specification (the specification for in-SOC IP interconnect developed by ARM and XILINX), with the addition of the Advanced System Bus (ASB) and advanced Peripheral Bus (APB) to the latest version of AMBA4.0, from the very beginning of the AMBA1.0 version definition to the AHB APB, the Advanced tracking bus ATB, et. The AHP APB Axi can be considered as the bus protocol or specification within the scope CPU, however we often refer to the

The rationale for this protocol is unclear, but the protocol (HTTP11NIOPROTOCOL) can improve the performance of Tomcat when high concurrency is pending.The default is http/1.1, which is the blocking type, After switching to Org.apache.coyote.http11.Http11NioProtocol, the request is processed in a non-blocking manner, which allows for a certain amount of concurrency, although, in later versions of tomcat7.0,

The previous article has introduced the composition of the Protocol. A protocol generally has the following features: protocol header + Length + Data + verification. The text format can intuitively define that carriage return and line feed are the end of the Protocol, therefore, we can omit the Data Length and add the

Label: PIM-Sm Multicast Route pi pim-DM Multicast Route IGMP MRT PIM-DM and PIM-SM are two different modes in multicast routing ASM (any source multicast. Compared with the multicast registration mechanism of PIM-SM, the diffusion mechanism of PIM-DM is more rough. 1. The PIM-DM does not need to register the pimreg virtual interface with the kernel. But like the PIM-SM, you need to add the layer-3 interface to the MRT multicast interface. To trigger the cache_miss message after the kernel

FTP text transfer protocol and FTP text transfer protocol I have always used AFNetworking to upload images in my development project. Recently, the boss said that I should use FTP to upload images, and there is very little information on the Internet. After all, this upload method is not used much now, it took a day to learn the FTP file transfer protocol. My per

updated. Because most users record domain names, this can reduce the impact of IP address changes. From the machine and technology perspective, domain names are not necessary. However, the Internet is composed of machines and users. Given the great help of DNS for users, DNS has been considered an indispensable part of the TCP/IP package. DNS Server The ing between domain names and IP addresses is stored in the DNS server. The so-called DNS server refers to some servers (computers) that
