Problems solved by technology

Due to cost reasons, the current commercial PC servers generally do not provide 10 Gigabit interfaces, but provide two to four Gigabit Ethernet ports. The traditional file system can only use one of the network interfaces due to the pre-set network interface. The maximum speed of the Gigabit Ethernet port is 100M, which seriously restricts the performance of the file system

Embodiment Construction

[0017] Refer below image 3 The adaptive network communication flow chart describes the content of the present invention with a specific example.

[0018] Assuming that node A wants to communicate with node B, first scan the local network interface to get two network interfaces 192.168.1.20 / 24 and 172.16.100.20 / 16, and then obtain the peer interface: 192.168.1.22 / 24, 172.16.100.22 / 24 , After obtaining the two interface groups, the interface group calculates the ip and mask, and finds that 192.168.1.20 and 192.168.1.22 can communicate directly, and 172.16.100.20 and 172.16.100.22 can communicate directly, thus generating two connections Yes, and found that the network interface type is different, the speed of the 192 connection pair is 1000M, and the speed of the 172 connection pair is 10000M.

[0019] The data is handed over to the connection group, first number the data, and then select a connection pair to send, because the speed of the two connection pairs is different, wh...

Abstract

The invention discloses a network self-adaptive method in a distributed file system. The distributed file system is deployed to multiple nodes, communication is carried out through a network, a network interface group is defined by the system, communication is carried out with the group as a unit, the network interface group is dynamically updated to be adapted to changes of network interfaces, the changes include increasing and decreasing of the network interfaces, and the network interfaces are dynamically used. By the adoption of the method, the distributed file system can be dynamically adapted to the network; when the network interfaces are increased, increased network interfaces can be automatically utilized, and bandwidths are automatically increased; when the network interfaces are damaged, the system automatically finds damage, data are transmitted through other network interfaces, and transparent processing on errors is achieved.

Description

technical field [0001] The invention relates to the field of distributed file systems, in particular to a method for the distributed file system to adapt to network changes. technical background [0002] With the advent of the era of cloud computing and big data, humans need to process more and more data. In order to support the huge amount of data, people use distributed file systems to store these massive data. Usually, distributed file systems use networks for communication. The performance of the network directly affects the performance of the distributed file system. [0003] Usually, when the file system is deployed, the network used needs to be set in advance. When the file system is running, the network interface cannot be changed. When the network interface fails, the node will be unavailable. Due to cost reasons, the current commercial PC servers generally do not provide 10 Gigabit interfaces, but provide two to four Gigabit Ethernet ports. Traditional file system...
