Internet Protocol IP is one of the two most important protocols in TCP/IP system. is also one of the most important Internet standard protocols. Address Resolution Protocol ARP Inter-Network Control Message Protocol ICMP Internet Group Management Protocol IGMP Virtual Interconnect NetworkThere is no single network that adapts to the needs of all users.In general terms, connecting the

During the time when I started network debugging, I always wanted to figure out how LAN access to the Internet was. Now pay attention to your computer. After the boot, after dozens of seconds of waiting, the operating system interface on the screen will appear in front of us. Just click on the browser icon to access our favorite website. However, nothing appears on the webpage as you think. What's wrong? Do

Overview of the Internet 1, three network integration: telecommunications network, cable TV network, computer network.2, the Internet's two basic features: connectivity and sharing. Connectivity (connectivity): The Internet allows internet users, no matter how far apart, ca

Computer network Overview 1. There are six articles in the previous "Computer Network" series, they are "Overview", "Physical Layer", "data link layer", "Network Layer", "Transport Layer", and "Application Layer". The transport layer is also called the transport layer, which

: Data from one point to another in the time spent on the network, including: Transmission delay (information from the head to the end of the beginning of the time spent), propagation delay (information in the channel time spent), processing delay (the host or route to information processing time spent), Queue delay (packet propagation passes through many routers, which are queued for processing after entering the router).5. Delay Bandwidth Product: =

Chapter 1 Overview Circuit Switching: The bit stream of the entire packet is continuously transferred from the source point to the end point, as if in a pipe. Packet Exchange: The entire packet is first transmitted to the adjacent node, all of which are stored and then searched for the forwarding table and forwarded to the next node. Group exchange: a single group (which is only a part of the entire packet) is sent to adjacent nodes. After the group is stored, it finds the forwarding table and f

: Segment) 5th level Span style= "Color:rgb (255,0,0)" > Session layer -establishes an end connection between two nodes. This service includes establishing whether the connection is set in full or half-duplex, although you can handle duplex mode in Layer 4 6th -formatted data, To provide a common interface for your application. This can include cryptographic service 7th Application layer -services directly to the application, which can vary, but include electronic message transmission Commo

integer byte. The true size of the different protocols is not the same.Network layer: The unit of transmission is a grouping (or a package), a grouping can contain multiple true, and the size of the grouping depends on the different protocols.Transport layer: in In TCP/IP protocol system,TCP is transmitted in data segment, andUDP is transmitted in datagram Unit .Session layer, Presentation layer, Application layer: transmission in a specific data message unitCommunication subnets and resource s

hosts. Class c ip Address class c ip Address: The network number is identified by a variable of 21 bits, and the variable eight bits identify the host number. The first three bits are "110 ". The first segment of the class C address is between 192 and ~ Between 223, the first, second, and third sections are combined to indicate the network number. The last section identifies the host number on the

. The MS Coco database was founded by Microsoft, and its challenge is currently run by a consortium of academic institutions in academia.The two challenges have different priorities: ImageNet tends to evaluate the ability to identify significant objects in an image, while Ms Coco tends to evaluate the ability to identify various objects in complex scenes. The ability to win a championship in two world-class competitions is enough to explain that the research team's technological breakthroughs ar

the packet (20.0.0.0 this network segment host). Similarly, 30.0.0.0 is directly connected to Router G.If we receive a packet, the destination is 10.0.0.0 this segment, the list is 20.0.0.5, is not directly connected, that needs to be dropped to the next router,router the corresponding port IP address is 20.0.0.5. Note that not a router an IP address, which is an IP address for each port of router. IP address is not a bound
