tolerated, so we adopt the UDP transport protocol. But the UDP protocol itself is non-connected and does not provide quality assurance. The high-level protocol rtp/rtcp based on UDP can provide traffic control and congestion control services together. The graph gives a RTP/UDP/IP-based H. 264 frame for video transmission.H. 264 RTP encapsulation strategy for vid

Routing protocol is divided into static routing protocol and dynamic routing protocol. There are many kinds of dynamic routing protocols, such as RIP, OSPF, EIGRP, and so on.1. RIP (Routing Information Protocol) is the first open standard used between router manufacturers. RIP has two versions: RIPv1 and RIPV2, which a

Preliminary Study on WCF-19: WCF Message Protocol, Preliminary Study on wcf-19 ProtocolWCFMessage Protocol Overview When a WCF application is generated, developers usually pay close attention to the data structure and serialization issues, rather than the message structure carrying data. For these applications, it is easy to create data protocols for parameters or return values. However, it is equally im

HTTP protocol learning and http protocol Learning 1. HTTP Overview HTTP is actually a set of language communication rules! Http uses a reliable data transmission protocol. Therefore, even if the data comes from the other end of the earth, it can ensure that the data is not damaged or messy during transmission. B/SStructure In the browser, the user requests the sp

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
