Abstract: An apparatus controls migration of a virtual machine between plural servers in a communication network. The apparatus acquires flow information by classifying, for each of virtual machines, pieces of data transmitted and received in each of the plural servers into flows having respective different destinations. The apparatus selects, based on the flow information, a migration target which is a virtual machine to be migrated from a first server whose number of virtual machines in operation is relatively large to a second server whose number of virtual machines in operation is relatively small, from among virtual machines in operation in the first server, by giving a higher priority to a virtual machine whose matching number of flows is larger, where the matching number of flows indicates a number of flows that are currently processed by both the virtual machine and the second server.

Abstract: The disclosed embodiments provide a system for densely storing strings within the memory of a software program. During operation, the system receives a set of characters to be stored in a string, wherein each character is encoded using a multi-byte public encoding. The system then stores the set of characters in the string at least in part by performing the following steps. The system determines whether every character of the set can be encoded using a first private encoding that consumes less space per character than the multi-byte public encoding. Responsive to determining that every character of the set can be encoded using the first private encoding, the system stores a particular value associated with the first private encoding in a particular field of the string. The system then stores the set of characters in the string in the first private encoding.

Abstract: First and second controllers implemented on computing equipment may be used to control switches in a network. The switches may forward network packets between end hosts. The second controller may identify first and second redundant partitions of switches in the network that are each coupled to all of the end hosts. The first controller may instruct the first partition to install software while the second partition forwards network traffic and may instruct the second partition to install software while the first partition forwards network traffic. The first controller may install the software while the second controller is active and the second controller may install the software while the first controller is active. In this way, the switches and controllers may be provided with an uninterrupted software upgrade and packets may be forwarded between end hosts during the software upgrade without introducing packet loss or other noticeable reductions in network performance.

Abstract: A method of testing a web service includes obtaining web service metadata from the web service. Test cases are generated automatically using the web service metadata, heuristic algorithm modules selected based on the contents of the web service metadata, and stochastic processes. Energy selection logic is used to update test parameters included in the test cases between rounds of testing until a set of test cases is generated that produces test results meeting one or more predetermined criteria. Testing is performed periodically using that set of test cases until the test results indicate that the web service has changed. New test cases are automatically generated and used to test the web service until test results meet the one or more predetermined criteria.

Abstract: A system and method of estimating impact of software updates includes obtaining usage measures for an instance of a software application, analyzing the software update of the software application by comparing base code for the software application to updated code for the software application, identifying one or more lines of interest from the base code based on the comparing, and aggregating the usage measures for the instance associated with the lines of interest to determine an impact factor. The base code corresponds to source code for the instance. The updated code corresponds to source code for the software application after the software update is applied to the base code. In some examples, the system and method further include normalizing the impact factor based on a length of time used to collect the usage measures, a number of lines of code in the base code, and a number of lines of code in the updated code.
