## Abstract

The present invention relates to a data processing system for providing business continuity protection, comprising: a business center comprising a first data processing unit, a first pre-communication unit, and at least a first post-communication unit; a disaster recovery center comprising a second data processing unit, a second pre-communication unit, and at least a second post-communication unit; wherein the first pre-communication unit and the second pre-communication unit are communicatively coupled to the first post-communication unit respectively when the business center operates normally; the first pre-communication unit and the second pre-communication unit are communicatively coupled to the second post-communication unit respectively when the disaster recovery center operates in place of the business center. The data processing system can reliably switch between the business center and the disaster recovery center, thereby providing a complete protection for the business continuity.

## Claims

### Claim 1

A data processing system for providing business continuity protection, comprising:
a business center, comprising:
a first data processing unit, configured to process various business data;
a first pre-communication unit, configured to perform data communication with an external unit via a network; and
at least a first post-communication unit, communicatively coupled to the first data processing unit and communicatively coupled to the first pre-communication unit in a configurable manner, wherein the first post-communication unit is configured to shield the first data processing unit from direct impact of external data and/or network status; and
a disaster recovery center, configured to be in a standby state when the business center operates normally, and to operate in place of the business center when the business center is out of order, wherein the disaster recovery center comprises:
a second data processing unit, configured to process business data when the disaster recovery center operates;
a second pre-communication unit, configured to perform data communication with the external unit via a network; and
at least a second post-communication unit, communicatively coupled to the second data processing unit and communicatively coupled to the second pre-communication unit in a configurable manner, wherein the second post-communication unit is configured to shield the second data processing unit from direct impact of external data and/or network status;
wherein the first pre-communication unit and the second pre-communication unit are communicatively coupled to the first post-communication unit respectively when the business center operates normally; and wherein the first pre-communication unit and the second pre-communication unit are communicatively coupled to the second post-communication unit respectively when the disaster recovery center operates in place of the business center.

### Claim 2 (depends on 1)

The data processing system according to claim 1, wherein the first pre-communication unit and the second pre-communication unit are communicatively disconnected from the second post-communication unit when the business center operates normally; and wherein the first pre-communication unit and the second pre-communication unit are communicatively disconnected from the first post-communication unit when the disaster recovery center operates in place of the business center.

### Claim 3 (depends on 1)

The data processing system according to claim 1, further comprising a parameter database, wherein the first pre-communication unit and the second pre-communication unit are synchronized to the parameter database respectively using data synchronization technology so as to obtain configuration parameters for the first pre-communication unit and the second pre-communication unit.

### Claim 4 (depends on 1)

The data processing system according to claim 1, wherein the first pre-communication unit and the second pre-communication unit are configured to perform data communication with external counterparts through communication links, respectively.

### Claim 5 (depends on 4)

The data processing system according to claim 4, wherein the first pre-communication unit and the second pre-communication unit perform data communication with the first post-communication unit or the second post-communication unit through communication links, respectively.

### Claim 6 (depends on 4)

The data processing system according to claim 4, wherein the business center comprises a plurality of the first post-communication units, the first pre-communication unit comprises a link managed sub-module, wherein the link managed sub-module is configured to establish a communication link between each of the external counterparts and the first pre-communication unit respectively, and establish a communication link between the first pre-communication unit and each of the first post-communication units respectively.

### Claim 7 (depends on 1)

The data processing system according to claim 1, wherein the first pre-communication unit is configured to allocate for each of the communication links between the first pre-communication unit and the external counterparts a buffer for storing valid business data received from the respective external counterpart.

### Claim 8 (depends on 1, 2, 3, 4, 5, 6, 7)

The data processing system according to any of claims 1 to 7, wherein the data processing system further comprises a switchover console, the switchover console is configured to be communicatively coupled to the first pre-communication unit and the second pre-communication unit, respectively, wherein the switchover console generates a switchover instruction for enabling the data processing system to switch between the following two states:
a first state in which the business center operates normally; and
a second state in which the disaster recovery center operates in place of the business center.
