摘要： Provided are an apparatus and a method for communication interface between application programs on virtual machines using a shared memory. The apparatus, includes: a request dividing unit for checking a type of socket request information transmitted from a first socket application program on a first virtual machine through a socket interface and dividing the socket request information based on the checked information; a Transmission Control Protocol (TCP) socket connecting unit setting up TCP socket connection with a second socket application program on a second virtual machine based on the divided socket request information for control request; and a shared memory connecting unit for setting up shared memory connection through the set up TCP socket connection and transmitting/receiving data with the second socket application program through the set up shared memory connection based on the divided socket request information for data transmission/reception.

摘要： Provided are a network scheduler and a network scheduling method capable of effectively managing network bandwidths by selectively supporting a work conserving mode to network entities by using an improved token bucket scheme. The network scheduler selectively supports a work conserving mode to network scheduling units (NSUs) serving as network entities by using a token bucket scheme, such that the network scheduler ensures an allocated network bandwidth or enables the NSUs to use a remaining bandwidth. The network scheduler manages the NSUs by classifying the NSUs into a green state, a red state, a yellow state, and a black state according to a token value, a selection/non-selection of the work conserving mode, and an existence/non-existence of the packet request to be processed.
摘要翻译：提供了一种网络调度器和网络调度方法，其能够通过使用改进的令牌桶方案选择性地将工作节约模式支持到网络实体来有效地管理网络带宽。网络调度器通过使用令牌桶方案选择性地支持作为网络实体的网络调度单元（NSU）的工作节约模式，使得网络调度器确保分配的网络带宽或使NSU能够使用剩余带宽。网络调度器通过根据令牌值将工作状态分类为绿色状态，红色状态，黄色状态和黑色状态来管理NSU，工作保存模式的选择/不选择以及存在/不存在 - 要处理的数据包请求的存在。
