Configuring cloud connections
About cloud connections
A cloud connection is a management tunnel established between a local device and the H3C Oasis
server. It enables you to manage the local device from the H3C Oasis server without accessing the
network where the device resides.
Multiple subconnections
After a local device establishes a connection with the H3C Oasis server, service modules on the
local device can establish multiple subconnections with the microservices on the H3C Oasis server.
These subconnections are independent from each other and provide separate communication
channels for different services. This mechanism avoids interference among different services.
Cloud connection establishment
As shown in
, the cloud connection between the device and the H3C Oasis server is
established as follows:
1.
The device sends an authentication request to the H3C Oasis server.
2.
The H3C Oasis server sends an authentication success packet to the device.
The device passes the authentication only if the serial number of the device has been added to
the H3C Oasis server. If the authentication fails, the H3C Oasis server sends an authentication
failure packet to the device.
3.
The device sends a registration request to the H3C Oasis server.
4.
The H3C Oasis server sends a registration response to the device.
The registration response contains the uniform resource locator (URL) used to establish a
cloud connection.
5.
The device uses the URL to send a handshake request (changing the protocol from HTTP to
WebSocket) to the H3C Oasis server.
6.
The H3C Oasis server sends a handshake response to the device to finish establishing the
cloud connection.
7.
After the cloud connection is established, the device automatically obtains the subconnection
URLs and establishes subconnections with the H3C Oasis server based on the service needs.
