Computer Network学习笔记_2 1_5 Traceroute,一种command tool,可以看network内部信息,ISP内部信息。 1_6 理解Network的模块化封装。学习Protocols和Layers,这种构建computer networks的关键机制。封装是越底层的protocol越封装在外面,形成一个protocol stack。每一层都在message加自己的header。当Browser和Server传输信息时...
This course is mainly about the data link layer, network layer and transport layer in the five-layer Internet protocol stack: Data link layer: CRC error detection and Ethernet Network layer: IP protocol, subnet mask and DHCP Transport layer: TCP and UDP protocol The Internet has five layers o...
1.2 Network Hardware(网络硬件) 从广义上讲,目前普遍使用的传输技术有两种,分别是广播式链路和点到点链路。 点到点(point-to-point)链路将一对单独的机器连接起来。在一个由点到点链路组成的网络中,为了从源端到达接收方,短消息必须首先访问一个或多个中间机器,这种短消息在某些情况下称为数据包或包1(packet)...
Computer Networking continues with an early emphasis on application-layer paradigms and application programming interfaces (the top layer), encouraging a hands-on experience with protocols and networking concepts, before working down the protocol stack to more abstract layers. ...
Many modern networks run on TCP/IP models, which include four network layers. Network access layer.Also called the data link layer or the physical layer, the network access layer of a TCP/IP network includes the networkinfrastructure(hardware and software components) necessary for interfacing with...
(WANs) including Wired, Wireless, Mobile, Cellular, Sensor, Optical, IP, ATM, and other related network technologies, as well as new switching technologies and the integration of various networking paradigms. 2. Communication Network Protocols: New design contributions on all protocol layers except ...
Here are the five layers of the TCP/IP model: image.png Application Layer Key Responsibilities of the Application Layer The main job of the application layer is to enable end-users to access the Internet via a number of applications. This involves: ...
-> the layers of peer system 2) Protocols arebuilding blocksof a network architecture 3) Each protocol object has two different interfaces -> Service interface: operations on this protocol -> Peer-to-peer interface: messages exchanged with peer ...
