Availability of the physical resources is determined according to the use. Server load is balanced according to the availability of the physical resources. According to another embodiment, the following is performed until a load is accommodated: selecting a server having a load that is less than an expansion threshold; loading the server until the expansion threshold is reached; selecting a next server having a load that is less than a next expansion threshold; and loading the next server until the next expansion threshold is reached. Load of a low load server is determined to be below a contraction threshold, and the low load server is drained. | 05-05-2011 |
20140149580 | TECHNIQUES FOR ACCOUNTING FOR MULTIPLE TRANSACTIONS IN A TRANSPORT CONTROL PROTOCOL (TCP) PAYLOAD - Techniques for separately accounting for multiple transactions in the same data packets communicated over a network using Transport Control Protocol (TCP) include receiving an Internet Protocol (IP) data packet that includes Transport Control Protocol (TCP) payload data. The TCP payload is parsed to determine boundary data that indicates a byte location on a boundary between a first transaction and a second transaction. A byte count that indicates a number of bytes in the TCP payload associated with the first transaction is determined based on the boundary data. Accounting data for the first transaction is determined based at least in part on the byte count. These techniques allow a service gateway to bill separately for different requests and responses carried in TCP data packets, such as those for Hypertext Transfer Protocol (HTTP) and Real Time Streaming Protocol (RTSP). | 05-29-2014 |
