摘要： The present invention relates to a method and network element for scheduling data transmission in a packet data network, e.g. a differentiated services network. Data traffic of a predetermined traffic class is classified based on a predetermined traffic profile, e.g. responsive or non-responsive traffic, and an in-profile rate of the data traffic is estimated. Then, a weight determining a transmit order of queued data packets of said predetermined traffic class is adjusted according to the estimated in-profile rate. Thus, the data traffic is marked into different classes based on the traffic profile and a queue scheduler improves fairness between the classified flows in the packet data network. Thereby, enhanced fairness between traffic profiles can be achieved easily and effectively.

摘要： Systems and methods for transmitting and updating information feeds from a server to a client are provided to increase bandwidth efficiency and improve the timeliness of information feed updates. Using OMA DS protocols, the updating of RSS feeds, for example, may be performed without having to transfer an entire RSS feed. That is, in some arrangements, only the new RSS items are synchronized with a client. A server may alert the client when a new RSS item has been added to an RSS feed. A synchronization session may then be initialized between the server and the client. A client may send a synchronization alert to the server identifying the feed or feeds for which synchronization is desired. The server may respond with one or more new items corresponding to the identified feeds. RSS item identification information may further be mapped between the client and the server.

摘要： A method for obtaining routing information relating to a routing path from a source node to a destination node among a set of nodes is discussed. The method comprises a step of sending a routing request from a current node, said routing request comprising information relating to a destination node location. At least one routing response is received in the current node, a routing response comprising information relating to a distance between a sender of the respective routing response and the destination node. A next node along the routing path is selected based at least on said distance between a sender of a routing response and the destination node. A node for an Ad Hoc network is also discussed.

摘要： A method and system for transmitting information between a sending means and a receiving means using packets for information transmission. The receipt of transmitted packets is acknowledged and unacknowledged packets are retransmitted from the sending means. The amount of transmitted unacknowledged information or the number of consecutive unacknowledged packets is detected, and the reason for information or packet loss is determined based on the amount of transmitted unacknowledged information or the number of consecutive unacknowledged packets. This amount is compared with a path maximum transmission unit (PMTU) to determine the reason for loss. A single or small number of unacknowledged packets is determined to be a result of Bit Error Rate (BER), whereas a larger number of consecutive unacknowledged packets may be determined to be congestion. Congestion control parameters are kept unchanged when the reason for loss is caused by Bit Error Rate (BER), whereas control parameters are changed when the reason for loss is congestion.
摘要翻译：一种用于在发送装置和接收装置之间使用用于信息传输的分组来发送信息的方法和系统。发送的分组的接收被确认，并且从发送装置重传未确认的分组。检测到发送的未确认信息的数量或连续的未确认分组的数量，并且基于发送的未确认信息的量或连续的未确认分组的数量来确定信息或分组丢失的原因。将该量与路径最大传输单元（PMTU）进行比较，以确定丢失的原因。一个或多个未确认的分组被确定为误码率（BER）的结果，而较大数量的连续未确认分组可被确定为拥塞。当丢包原因是由误码率（BER）引起的，拥塞控制参数保持不变，而丢失原因拥塞时控制参数会发生变化。

摘要： A modular three-dimensional (3D) optical switch that is scalable and that provides monitor and control of MEMS mirror arrays. A first switch module includes an array of input channels. Light beams received from the input channels are directed toward a first wavelength selective mirror. The light beams are reflected off of the first wavelength selective mirror and onto a first array of moveable micromirrors. The moveable micromirrors are adjusted so that the light beams reflect therefrom and enter a second switch module where they impinge upon a second array of moveable micromirrors. The light beams reflect off of the second array of moveable micromirrors and impinge upon a second wavelength selective mirror. The light beams reflect off of the second wavelength selective mirror and into an array of output channels. The alignment or misalignment of a data path through the switch is detected by directing two monitor beams through the data path, one in the forward direction and one in the reverse direction. The position of each of the monitor beams is detected after its reflection from the second moveable micromirror that it hits. The position data is used to determine the angles of the moveable micromirrors in the data path.
