Abstract
The invention relates to the field of data synchronization methods, in particular to a network equipment cluster data synchronization method, which can increase network equipment members in a cluster, does not need independent network interconnection to carry out data synchronization, and transmits synchronous data to each member node by using multicast and broadcast messages in a two-layer network, thereby breaking through the limitation of the cluster number of a data synchronization scheme which is independently carried out by a data synchronization line.
Description
Technical Field
The invention relates to the field of data synchronization methods, in particular to a network equipment cluster data synchronization method.
Background
Taking a firewall network device as an example, at most 2 firewalls in the market currently serve as a cluster, and the 2 firewalls synchronize important data (such as firewall session information) by using one interconnected network line, but the number of members of the network device in the network device cluster cannot exceed 2 and a separate data synchronization network line is needed for interconnection communication.
Disclosure of Invention
The technical problem to be solved by the present invention is to overcome the defects in the prior art, and to provide a network device cluster data synchronization method based on multicast or broadcast messages.
The invention is realized by the following technical scheme:
a network equipment cluster data synchronization method is characterized by comprising the following steps:
a. isolating a network area by adopting a two-layer VLAN technology to serve as a data synchronization network area of the network equipment cluster;
b. dividing the data synchronization interface of the network equipment member in the network equipment cluster into the data synchronization network area in the step a;
c. packaging synchronous data by using the multicast or broadcast MAC address and the IP address to form a synchronous data message;
d. marking the VLAN label of the data synchronization network area on the packaged synchronization data message to form a cluster synchronization message, and then sending the cluster synchronization message to a switch;
e. the exchanger receives and identifies the cluster synchronous message, and copies and sends the cluster synchronous message to all data synchronous interfaces belonging to the data synchronous network area;
f. and other network equipment in the network equipment cluster receives the cluster synchronization message, decapsulates the cluster synchronization message, and extracts corresponding data information to complete data synchronization.
The invention has the beneficial effects that:
the invention can increase network equipment members in the cluster, does not need to carry out data synchronization by independent network line interconnection, and transmits the synchronous data to each member node by multicast and broadcast messages in a two-layer network, thereby breaking through the cluster quantity limitation of a data synchronization scheme by independently depending on a data synchronization line.
