Frame structure, ensure to be maintained secrecy on Internet protocol (IP) network by using the security service of encryption and safety it is logical
News) the hot standby reliability of data mode, i.e., data are classified backup information according to data id by host, and every class data have
The sequence number of oneself is simultaneously safeguarded；Standby host then judges whether data are distorted according to sequence number, and then whether determination data needs
It corrects.
As shown in Fig. 2, after the optimization, host first can distinguish data flow according to data id and generate one for each data flow
A sequence number, standby host receive batch standby data (i.e. the data of batch backup are the data generated in real time in host operational process)
Afterwards, standby host is inquired according to data id and whether has backed up the data flow, without then creating node and life span is arranged (i.e. standby host connects
The waiting time that each data flow to next data flow is received, depending on data volume, such as 15 or 16 minutes, it is more than life span,
Next data flow is not received, then the data flow is deleted, and sends backup request to host again according to data ID), data later
It is cached；Have, the sequence number of data is verified, (data flow such as received is imperfect if sequence number is abnormal
Or sequence error, be accordingly to be regarded as exception), then standby host deletes paid-in data, rear sent to host request, it is desirable that back up again
Specified data.In the case where sequence number is errorless, standby host checks whether critical data is here, here then to apply data；It is no
Then by data buffer storage, and whether the life span of detection node is out of date, the life span without then more new node, there is then deletion pair
The node and related data answered send backup request to host again according to data ID.
Specific 1+1 backup application scenarios, as shown in figure 3, Femto gw A is host, Femto gw B is standby host:
1, after Femto gw A and AP (base station) generates interaction data, data id, addition sequence are generated according to corresponding algorithm
