The invention discloses a distributed file system architectural method supporting mass data access. The method is based on a distributed Hash table, and access nodes are obtained by conducting Hash mapping on a file path. By the adoption of the fully distributed type non-centralized architectural design, new nodes can join a cluster after several times of communications. A Kademlia algorithm is adopted for addressing among the nodes, and a routing table is divided and the distance between the nodes is obtained through exclusive-or operation to achieve skip of the most adjacent nodes. A leader is selected through a PaxosLease algorithm to handle the mapping operation on the nodes so as to solve the consensus problem. Block storage of fixed size is conducted on actual data of files, and redundant backup is conducted on the multiple nodes, so that the requirements for safety and distributed calculation are met. When an architectural system generated according to the architectural method processes mass files, the processing efficiency can be remarkably improved, and the good effect can be achieved in the environment with the low latency requirement.

The invention relates to a group data managing method based on PoC and relative system. Wherein, it mainly comprises: first, storing the data management rule of said group in the group data server, while said rule records the priority information of user terminal that modifying the group data; then, when the user terminal sends information that operating on the group data of group data server, the group data server, according to the data management rule and the operation sent by user terminal, operates the group data. With said invention, the group data management rule can be defined by the Owner of group, to be stored in group data server; then other common members can modify the group character limited by said rule, to realize the operation that adding or leaving the group.

The invention provides an SSL / TLS protocol plaintext data acquisition method based on a mirror image flow, comprising the following steps: (1) receiving SSL / TLS data packets of mirror images, extracting records in the data packets, generating a plurality of complete records, and putting the records in a record queue; (2) extracting a plurality of complete messages from the records in the record queue, and putting the messages in a message queue; and (3) analyzing the messages in the message queue to get plaintext data. According to the method of the invention, the data packets are spliced into complete records according to the package format of an SSL / TLS protocol, and complete single messages are extracted and processed. There is no need for a server to synthesize multiple messages into one record or package a single message into multiple records. New messages needing analysis can be selected and added flexibly. The method is of good scalability. Plaintext data is obtained by processing image data of a switch without interfering with the original service of the system or affecting the system performance.
