Latency data associated with accessing a first endpoint within a network by end user devices from a plurality of geographic regions is collected, wherein the end user devices are associated with a plurality of customers. Performance scores for the geographic regions are calculated based on the latency data. A subset of the performance scores of one of the plurality of customers is selected. A second endpoint is identified within the network for the one of the plurality of customers based on the selected performance scores. The second endpoint is established for the one of the plurality customers for network traffic originating from the one or more of the geographic regions to reduce latency.

  • Publication number: 20200057037
    Abstract: A rotating buffer station for a chip mainly comprises an upper cover plate, a rotatable plate, a movable jaw member and a lower base. The upper cover plate is arranged on the lower base and formed with a guide slot. The rotatable plate is located between the lower base and the upper cover plate and formed with a cam slot. The rotatable plate is pivotally coupled to the lower base. The movable jaw member is slidably engaged with the cam slot and the guide slot. When the rotatable plate is rotated, the cam slot forces the movable jaw member to move radially along the guide slot so as to form a chip socket. Accordingly, with rotation of the rotatable plate, the cam slot forces the movable jaw member to move radially along the guide slot so that the chip socket can be resized to hold various differently-sized chips.
