摘要： A method and system for distributing and enforcing security policies is provided. A firewall agent executing at a host computer system that is to be protected receives security policies for the enforcement engines responsible for enforcing the security policies on the host computer system. A security policy has rules that each provide a condition and action to be performed when the condition is satisfied. A rule also has a rule type that is used by the distribution system to identify the security components that are responsible for enforcing the rules. To distribute the security policies that have been received at a host computer system, the firewall agent identifies to which enforcement engine a rule applies based in part on rule type. The firewall agent then distributes the rule to the identified enforcement engine, which then enforces the rule.

摘要： A method and system for controlling access to files in a remote file system is provided. In one embodiment, a firewall system at a client computer system intercepts requests originating from the client computer system and sent to the remote file system for accessing remote files, that is, files stored on a server computer system. Upon intercepting a remote file access request (e.g., to open a remote file), the firewall system determines whether the file access request should be allowed based on access control criteria.

摘要： A centrifugal compressor includes an asymmetric self-recirculating casing treatment that includes, on an inner face of a casing 10, a suction ring groove 1, a ring guide channel 2 and a back-flow ring groove 3 to form a self-recirculating channel. An axial distance Sr from an upstream end face of the suction ring groove 1 to an impeller full blade leading edge 4 or a width br of the suction ring groove 1 is represented as A·sin(α+θ0)+A0 and is distributed in a sinusoidal shape in a circumferential direction, an initial phase angle θ0 is in a range of 0°≤θ0≤360°, and a circumferential angle α of the casing 10 has a definition range of θ0≤α≤θ0+360°. In the expression, A denotes amplitude of distribution of the axial distance Sr or the width br, and A0 denotes an average of the axial distance Sr or the width br.

摘要： A centrifugal compressor has a casing 7. In the casing 7 is formed a back-flow channel 9 to return fluid from a downstream position of an impeller full blade leading edge 6a to an upstream position of the impeller full blade leading edge 6a. The back-flow channel 9 includes a suction ring groove 9a and a back-flow ring groove 9b. The suction ring groove opens at the downstream position on the inner face 7a of the casing 7, and extends in the circumferential direction. The back-flow ring groove opens at the upstream position on the inner face 7a, and extends in the circumferential direction. Distribution in the circumferential direction of the axial-direction position of the suction ring groove 9a or a width of the suction ring groove 9a is asymmetric with reference to the rotation axis.
