A part may have a locking arm with a guide surface only on one side which produces the rotational movement during the displacement of the parts and bears against a complementary guide surface of the other part.

A method and apparatus providing highly scalable server load balancing are disclosed. Data packets from a client are routed through one or more routers to a server load balancer, which is selected from among a plurality of server load balancers in a network. In response to receiving a request packet, a particular server site to process the client request is selected. A first path to a second router associated with the particular server site, and a second path to a server load-balancing device associated with the second router, are determined. A mapping of flow identifying information, associated with the packet, to a first label value that identifies the first path and to a second label value that identifies the second path, is created. The first label value and the second label value are stored in the packet. All subsequent packets associated with the client request are forwarded to the server load-balancing device based on looking up the first label value and second label value in the mapping. As a result, a network is scalable to process and load-balance numerous client requests, which are efficiently routed to the site, server load-balancer, and server that are handling the request.
