Preface

network card bond It is through binding multiple network cards to a logical network card , Realize the redundancy of local network card , Bandwidth expansion and load balancing . It is a common technology in application deployment , Our company basically all project related servers have done bond, Here is a summary , For further investigation .

bond Pattern

When linux There are multiple separate network cards on the system , And want to make full use of these network cards , At the same time, provide a unified network address , With
Make the throughput of the network increase , At the same time, it also improves the availability of the network , It's time to bond To help us solve this problem .
linux in bond I feel a little bound and bind It means , Literally , We can see that bond Its function is polymerization
Many things , Combine into a unified thing to use .

1. Let's first look at the active / standby mode
In active standby mode ,Linux Bonding Implementation will Bond Of the two slave Net mouth MAC The address is changed to Bond Of MAC Address ,
and Bond Of MAC The address is Bond After the creation starts , Main use slave Net mouth MAC Address .

2. Look at the load balancing mode
In load balancing mode ,Linux Bonding The implementation can keep two slave Net mouth MAC The address remains the same ,Bond Of MAC The earth
The address is one of the network cards ,Bond MAC The choice of address is based on Bond An algorithm implemented by myself , How to choose
Alternative has not been studied .

3. Link aggregation is the function of using multiple physical links to create a logical link between two devices . This method allows physical links
Shared load .
