  • Patent number: 8375433
    Abstract: The present invention relates to a method for multi-core processor based packet classification on multiple fields. The invention specifically proposes three methods to select partition points, two associated methods to select dimensions, then receiving packet information after the data structure of classification is constructed, and searching the data structure of classification according to packet information to get matched results. The present invention can be implemented on many types of multi-core processor based platforms which ensure favorable performance and adaptive capabilities for different network applications, and significantly reduce the product cost of high-end routers and firewalls.

  • Publication number: 20120103774
    Abstract: A switch operator is provided that includes a single piece actuator shaft coupled to a single piece cap. According to certain embodiments, the actuator shaft may be snap fit to the cap. The cap may include an annular sleeve and an annular skirt that extend orthogonally from the cap. The sleeve includes recesses that receive tabs of the actuator shaft to couple the actuator shaft to the cap. In certain embodiments, the actuator shaft may include slots that allow the actuator shaft to flex upon attachment to from the cap. A bushing encircles the actuator shaft and extends into the cap where the bushing is disposed between the annular sleeve and a skirt. The actuator shaft also includes a pair of diametrically opposed slots that house a detent assembly. The detent assembly may be employed to retain the switch operator in the actuated position and in the unactuated position.

  • Publication number: 20120103769
    Abstract: A latch assembly is provided for securing a switch operator to a contact block. The latch assembly includes a collar designed to retain the switch operator in the latch assembly. The latch assembly also includes a housing having one or more apertures for receiving fasteners to secure the contact block to the latch assembly. The collar is displaceable within the housing between a locked position that secures the switch operator and an unlocked position that permits disengagement of the switch operator from the collar. When the collar is in the locked position, corresponding apertures in the collar align with the one or more apertures in the housing, permitting the fasteners to be inserted through the collar apertures. Insertion of the fasteners through the collar apertures secures the collar in the locked position, thereby impeding unintentional disconnection of the switch operator from the latch assembly.

  • Patent number: 7954205
    Abstract: The present invention discloses a clip retainer which includes a top surface having a groove and a bottom surface which has stopping ribs and a barb formed between the stopping ribs. The top surface and the stopping ribs of the bottom surface clamp a flange of a clip. A slope of an inclined plane of the barb in a slide-in direction of the clip is smaller than that of an inclined plane of the barb in a slide-out direction of the clip. Based on the above structure, the clip retainer can meet the function requirements of small slide-in force and large slide-out force of the clip and has a simple structure. Furthermore, the clip retainer can produce repeated insertion and extraction deformation and is very reliable to use.

  • Publication number: 20100192215
    Abstract: The present invention relates to a method for multi-core processor based packet classification on multiple fields. The first step involved in this invention involves constructing a data structure of classification, which includes selecting a certain dimension such that the sum of the rules that fall into two rule sub-sets of two subspaces is as small as possible after spatial partition through a certain partition point in which the method to determine the partition point on the selected dimension is to select the partition point on the dimension such that the number of rules that fall into the two sub-spaces after partition by the point is equal to each other as much as possible. The invention specifically proposes three methods to select partition points, two associated methods to select dimensions, then receiving packet information after the data structure of classification is constructed, and searching the data structure of classification according to packet information to get matched results.
