摘要： According to an example, to load balance a group of servers, a service access request message is sent by a client terminal and is received at a load balancing device, wherein a source Internet Protocol address of the request message is an Internet Protocol address of the client terminal of a first protocol version. A server is selected from the group of servers to send the request message. A determination is made as to whether the first protocol version is same as a second protocol version of an IP address of the selected server. If the versions are the same, the request message is sent to the selected server. Otherwise, network address translation is performed to replace the source Internet Protocol address of the request message with an Internet Protocol address of the second protocol version to send the request message.

摘要： Compressed recorded video is to be transmitted over a variable bit-rate link, using bandwidth reservation. In order to determining the transmission rate that is to be used (and reserved) at any given time, in such a way as to make the two match so as to minimise wasted bandwidth, the data stream is split into chunks chosen such that the average bit rate for the chunk as a whole is no less that the average bit rate for any shorter chunk starting at the same point. The chunk can then be transmitted using this average rate without any buffering problems. Preferably one chooses chunks so that the average bit rate for the chunk is no less than that for any shorter or longer chunk starting at the same point. This has the benefit that a request for bandwidth never has to ask for an allocation that is higher than that specified in any previous such request. In systems that switch between streams of different degrees compression. the switching points can with advantage be chosen to coincide with the inter-chunk boundaries.

摘要： A system for enhancing steam distribution in a thermal stimulation phase, and for reducing the production of particulate matter with hydrocarbon fluids in a production phase, has a base pipe with a limited number of spaced-apart holes. The spaced-apart holes are sized and located so that steam is uniformly distributed in the reservoir. A collar is disposed around each hole to deflect the steam into an annulus between the base pipe and a wire-wrap screen section to avoid erosion and deterioration of the wire-wrap screen, which is required in the production phase. Mobilized hydrocarbon fluids flow to the wire-wrap screen section, which acts to filter particulate matter so that the production of particulate matter with hydrocarbon fluid is limited. The open area in the base pipe is significantly reduced, as compared with conventional methods, so that at the design injection rates, the pressure drop through the spaced-apart holes is larger than the pressure drop along the base pipe. During hydrocarbon fluid production, the pressure drop from the reservoir to the spaced-apart holes is low due to the presence of the wire-wrap screens. The open area in the base pipe while significantly reduced at the design production rates, as compared with conventional methods, should not unduly limit production rates.
摘要翻译：用于增强热刺激阶段中的蒸汽分布并且用于在生产阶段中用烃流体减少颗粒物质的产生的系统具有具有有限数量的间隔开的孔的基管。间隔开的孔的尺寸和位置使得蒸汽均匀分布在储存器中。围绕每个孔设置套环以将蒸汽偏转到基管和电线包裹屏部分之间的环形空间中，以避免在生产阶段所需的电线包裹屏幕的侵蚀和劣化。流动的碳氢化合物流体流入绕线筛网部分，其用于过滤颗粒物质，使得具有烃流体的颗粒物质的产生受到限制。与常规方法相比，基管中的开口面积显着减小，使得在设计注射速率下，通过间隔开的孔的压降大于沿着基管的压降。在烃流体生产期间，由于存在电线包裹屏幕，从储存器到间隔开的孔的压降很低。与常规方法相比，基管中的开放面积以设计生产率显着降低，不应过度限制生产率。
