List of articles
1.IP agreement
The network layer is located between the data link layer and the transport layer . The network layer contains many protocols , The most important one is IP agreement . The network layer provides IP Routing functions , understand IP In addition to being familiar with routing IP Outside the working mechanism of the agreement , You must also understand IP Address and how to use it reasonably IP Address to design the network .
IP Baotou structure
- version
- Header Length
- Differentiated Services Filed
- Differentiated Services Codepoint
- Explicit Congestion Notification
- Identification
- Flags
- Fragment Offset
- Time to Live
- Protocol
- Header Checksum
- Source IP Address
- Destination IP Address
- IP Options
2.IP Field
Fragmentation
Fragmentation : When packets are smaller than links MTU Big time , Can be broken down into many small enough fragments .
TTL:Time to Live, Time to live
- prevent IP Packets are transmitted endlessly in the network
- Every time you go through a route TTL The value will decrease 1
- When TTL=0 At the same time , Discard packets
Agreement No
- Used to identify the upper layer protocol
3.IP Address
- stay IP In the network , The communication node needs a IP Address
- Expressed in dotted decimal system , from 32 A composition
- It is divided into Network bit and Host bit Two parts :
- Network bit , representative IP The segment to which the address belongs
- Host bit , Represents a node on a network segment
- from Subnet mask Determine the dividing point
IP Address classification
According to the first set of octets
