Chapter 3 Transport Layer Introduction of Transport-Layer Servicers (传输层提供的服务) 传输层将网络层所提供的主机到主机之间的逻辑通信(logical comminication)扩展为进程到进程间的通信 =>!!最主要的的功能 传输层只在端系统(end systems / hosts)中才有,在路由器和二层交换机上没有...
Services Provided to Application Layer:TCP/IP UDP Transport Service Primitives 传输服务原语 Addressing 寻址 当一个应用进程希望与另一个远程应用进程建立连接时,它必须指定要连接到哪个应用进程上(无连接传输也有同样的问题:消息发给谁)。通常的方法是为那些能够监听连接请求的进程定义相应的传输地址。在Internet中,...

Application Layer Protocol Negotiation (ALPN) Two network peers may want to use a custom application protocol to communicate with each other. One way to resolve this is to determine the protocol upfront, assign a well-known port to it (e.g., port 80 for HTTP, port 443 for TLS), and ...
Theoretically, the presence of Weyl fermions has been predicted for SrRuO3, a 4dferromagnetic material7. SrRuO3is widely used as an epitaxial conducting layer in oxide electronics and spintronics owing to the unique nature of ferromagnetic metal, compatibility with other perovskite-structured oxides, ...
