摘要： Provided are a load balancing apparatus, which is configured to prevent an overload from occurring and perform effectively a load balancing operation even for servers distributed throughout a network, and a load balancing method performed using the same. the method may include determining whether a data packet received from a client may be a packet requiring a load balancing operation, determining at least one of physical servers provided in a distributed server farm as an target server to provide a service to the client, depending on the judgment, determining a forwarding path between the client and the target server, determining a header rewriting node, and referring the forwarding path and the header rewriting node to determine a forwarding rule and load the forwarding rule on a switch provided on the forwarding path.

摘要： Provided are a method and an apparatus for periodically measuring speech quality in a voice over Internet protocol (VoIP) terminal while a VoIP call between VoIP terminals is in progress. The method comprises: receiving summary information regarding traffic sent from an opposite VoIP terminal; and evaluating speech quality by comparing the summary information with actually received information regarding the traffic sent from the opposite VoIP. Accordingly, each VoIP terminal can precisely evaluate the speech quality periodically and send the evaluation result to each other.
