Abstract: Methods and apparatus are provided for tuning a garbage collection algorithm. The apparatus includes a request generator configured to generate a transaction request including parameters Ta, Te, and M, where Ta represents a transaction request inter-arrival time, Te represents a transaction request execution time, and M represents a transaction request memory allocation amount. The apparatus also includes a memory allocation module, an active request queue, and a garbage collection (GC) module. The memory allocation module is configured to admit the formatted transaction request to the queue if at least M heap memory is available, and to initiate a GC routine if M heap memory is not available.

Abstract: In accordance with embodiments, there are provided mechanisms and methods for facilitating dynamic load balancing at application servers in an on-demand services environment. In one embodiment and by way of example, a method includes polling a plurality of application servers for status, receiving status from each of the plurality of application servers, assigning a priority level to each of the plurality of application servers based on its corresponding status, and facilitating load balancing at the plurality of application servers based on their corresponding priority levels.

Abstract: Methods and systems for communicating in a wireless network using time division duplex (TDD) protocols. The ratio for uplink and downlink subframes of a physical frame may be dynamically adjusted as traffic stream requirements of the wireless network change. In certain embodiments, the wireless network is a wireless metropolitan area network (WMAN) utilizing orthogonal frequency division multiplexing (OFDM). Various specific embodiments and variations are also disclosed.
