Abstract: A bolt sleeve connector, a blade of a wind turbine generator system and manufacturing method thereof and a wind turbine generator system are provided. The bolt sleeve connector includes at least two extension portions arranged side by side and spaced apart, and each extension portion has a first end and a second end. The first ends of the extension portions are connected together and the second end of each extension portion is connected with the corresponding bolt sleeve. By using the bolt sleeve connectors to connect multiple pre-embedded connection sleeves at the position of the blade root of the blade of the wind turbine generator system, the multiple pre-embedded connection sleeves are connected as a whole, thus can disperse the stress of the bolt and the bolt sleeve and then improve the bearing capacity of the blade root bolt and facilitate reducing the weight of the blade root.

Abstract: A technology is described for prioritizing DNS name resolutions requests received from DNS resolvers. An example method may include identifying a resolver as a public DNS resolver. Receiving a DNS name resolution request from the public DNS resolver. Assigning a priority to the DNS name resolution request received from the public DNS resolver that is lower priority as compared to a priority assigned to DNS name resolution requests received from known DNS resolvers, and providing the DNS name resolution request to the DNS name server according to the priority assigned to the DNS name resolution request.

Abstract: A technology is described for prioritizing DNS name resolutions requests received from DNS resolvers. An example method may include receiving a DNS name resolution request addressed to a DNS name server from a DNS resolver. The DNS resolver associated with the DNS name resolution request may be identified as a known DNS resolver or an unknown DNS resolver, where a known DNS resolver may have DNS resolver characteristics that correspond to a valid DNS resolver. The DNS name resolution request may be prioritized according to the identity of the DNS resolver as a known DNS resolver or an unknown DNS resolver. The DNS name resolution request may then be provided to the DNS name server according to the priority assigned to the DNS name resolution request.

Abstract: A technology is described for prioritizing network packets using suspicion weights assigned to packet attributes of the network packets. An example method may include analyzing a network packet for packet attributes that have values indicating that the network packet may be associated with a potential network attack. Suspicion weights for the packet attributes identified as having a value that indicates that the network packet is associated with the potential network attack may be obtained, and a suspicion score may be calculated for the network packet using the suspicion weights.
