摘要： Exemplary embodiments may involve a meta-data server that manages data-server access control list (DS ACL) information. Each entry of this DS ACL information may include an address of a data server, an identification or a range address of chunk data on the data server, a file path of the chunk data in the file tree provided by the meta-data server, and addresses of the permitted clients. The meta-data server may determine the addresses of the permitted clients for the chunk data by retrieving the original file path of chunk data from layout information of the meta-data server, and by retrieving the entry containing the directory path that partially matches with the original file path from an access control list of the meta-data server.

摘要： In a network where network address translation (NAT) has been introduced, a problem occurs in which, when an IP host operating in a network is automatically categorized with automatic IP host discovery using an ARP cache, a plurality of IP hosts with the same IP address are recognized as one IP host by NAT. To resolve this problem, a network management server specifies network sub-topology on the basis of topology information, public addresses translated by NAT, and IP host corresponding relationships.

摘要： The purpose of the invention is to provide a distributed cache system applicable to a large-scale network having multiple cache servers. In a distributed cache system including multiple cache control servers, the content information is divided and managed by each cache control server. When content requested from a client is stored in the distributed cache system, a cache cooperation router forwards the content request to the cache control server which manages the information of the requested content. A cache control server has a function to notify its own address to the distributed cache system when the cache control server is added to the distributed cache system. When a cache control server receives the notification, it sends content information to the new cache control server and synchronizes the content information. Thus, a cache control server can be added to the system with ease.

摘要： A failure factor can be promptly carved up by effectively prioritizing the ports to which MEPs are assigned in a condition where the maximum number of MEPs is limited. A network monitoring server monitors a network having plural switch devices. The plural switch devices each have a communication confirmation function using transmission and reception of a monitoring frame between ports. An upper limit is set to the number of ports to which maintenance end points (MEPs) are assignable among the respective ports of the plural switch devices. The network monitoring server calculates, for each of the plural switch devices, a monitoring priority corresponding to the probability of failures of a device connected to a network path including the port or the port, and generates data for displaying the calculated monitoring priority of each port in association with each port.

摘要： In a system having physical machine resources and network component resources, a resource management technique is provided that is effective for deploying virtual machines utilizing these resources. A surplus policy regarding surplus resources is prepared as a parameter adjustable by the system administrator. A placement plan generating program at a VM placement plan generating server generates placement plans for virtual machines in response to alteration of the surplus policy. Then, a placement plan verification program at the VM placement plan generating server validates whether each of the created placement plans complies with the altered surplus policy. This validation is performed by simulating the amounts of utilization of both physical machine resources and network component resources. The VM placement plan generating server presents the placement plans that passed this validation, as those causing no problem in performance, to the system administrator through the use of an administrator terminal.
