An internet layer is a second layer of TCP/IP layes of the TCP/IP model. It is also known as a network layer. The main work of this layer is to send the packets from any network, and any computer still they reach the destination irrespective of the route they take. The Internet lay...
网络层(Network Layer):负责在数据链路层上建立逻辑连接,选择最佳传输路径,进行数据包的传输和路由选择 数据链路层(Data Link Layer):负责在物理层上建立数据链路,进行数据帧的传输和接收,并进行错误检测和纠正 物理层(Physical Layer):主要负责传输比特流,包括建立物理连接、信号编码、调制解调制等 TCP/IP模型 TCP/...
The TCP/IP model consists of five layers: the application layer, transport layer, network layer, data link layer and physical layer. The first four layers provide physical standards, network interface, internetworking, and transport functions that correspond to the first four layers of the OSI mode...
Second, TCP connections are connection-oriented. Before data can be transferred, two Application Layer processes must formally negotiate a TCP connection using the TCP connection establishment process. Similarly, TCP connections are formally closed after negotiation using the TCP connection termination proces...

ACM Computer Communications Review | October 2003 Published by Association for Computing Machinery, Inc. 下载BibTex This paper discusses a link layer approach to improving TCP performance in the face of periodic network disconnections. Network disconnections are encountered in many sce...
2011 年 8 月,IETF 发布了 RFC 7348 草案《Virtual eXtensible Local Area Network (VXLAN): A Framework for Overlaying Virtualized Layer 2 Networks over Layer 3 Networks》,主要由 VMware 与 Cisco 公司草拟。该技术利用 L2 over UDP 机制传输原始报文、利用 VxLAN 头中 24bits 的 VNI 信息将传统 VLAN 标...
howinternetworks(interconnected networks) function. The network layer is the lowest one in the OSI model that is concerned with actually getting data from one computer to another even if it is on a remote network; in contrast, the data link layer only deals with devices that are local to ...
The IP layer then passes datagrams down to the network interface layer. At this layer, data-link services convert IP datagrams into frames for transmission over network-specific media on a physical network. This process happens in reverse order on the destination host....
