摘要： There is provided a method for providing edge node (110) fault management and bandwidth, (BW), control for transmission of a data stream in a packet-based network. The method comprises adaptively transmitting a data stream (DS) by controlling an outgoing data stream being transmitted to one or more client devices (151, 152, 153) by analyzing at least one data stream characteristics of a corresponding received data stream (DS1, DS2, DS3) of the one or more receiving client devices (151, 152, 153), and providing a transmission strategy for the outgoing data stream based on said analyzed data stream characteristics. Thereby accurate adjustment of consumed (BW) and an associated recovery scheme, i.e. FEC and/or retransmission, to maintain highest achievable performance when it comes to video quality and also affect on other services, are provided.

摘要： There is provided a mechanism for providing Adaptive Bit Rate (ABR) adjustments of media streams like video for live Over the Top (OTT) distribution without the need to monitor buffer fill levels, which is advantageous for live video distribution over IP networks. The invention is based on monitoring change Δ in the received bitrate level BR(t) at a client device, and providing a predicted future bandwidth characteristics of the network based on the change. By monitoring the received bitrate and its rate of change over time, a prediction of (near future) available bandwidth in the network is advantageously provided. A drastic drop of the received bitrate may for instance indicate that the available bandwidth will become too low to sustain a currently received media stream, and the system can accordingly initiate a decision to request a lower video quality.

摘要： There is provided an improved redundancy method for a communication network. The method for node to node communication comprises the steps of providing each packet of a data stream (11) to be transferred with a respective identifier, then transporting over at least two links (A,B) replicated data of the data stream from a transmitting node (N0) to a receiving node (N1), and at the receiving node receiving and buffering packets from the at least two links for subsequent forwarding of the data stream. The identifier corresponds to a relative position of a packet in the data stream, and the step of buffering comprises reconstructing using received packets from at least one of the at least two links a predetermined portion of the data stream in a common indexed buffer. The invention is based on the insight that a hitless failover can be performed by at the receiving node using a single common indexed play-out buffer in which a selective reconstruction of the transported data stream utilizing individual pieces, i.e. frames or packages, of a data stream received over multiple links is performed.
摘要翻译：提供了一种用于通信网络的改进的冗余方法。用于节点到节点通信的方法包括以相应的标识符提供要传送的数据流（11）的每个分组的步骤，然后通过至少两个链路（A，B）传输数据流的复制数据，节点（N0）发送到接收节点（N1），并且在接收节点处接收和缓冲来自至少两个链路的分组，用于随后转发数据流。标识符对应于数据流中的分组的相对位置，并且缓冲步骤包括使用来自至少两个链路中的至少一个的接收分组来重建在公共索引缓冲器中的数据流的预定部分。本发明基于以下认识：可以在接收节点使用单个公共索引播出缓冲器执行无命中故障切换，其中使用数据的单个片段（即，帧或包）的传输数据流的选择性重建执行通过多个链路接收的流。

摘要： There is provided a compression method for TDM frames transported over a packet network. The method is based on mapping of allocated TDM slots but not all un-allocated slots into a transport structure, which thereby reduces the needed amount of data transported over packets and hence reduces the required packet rate and packet capacity during transport of the TDM frame. The mapping is further arranged to allow dynamic changes of packet rate and packet capacity, thus the mapping is performed such that a working size of the transport TDM frame is allowed to increase or decrease over time. Further, mechanisms to lower experienced delay for low-rate signals are provided.
摘要翻译：提供了通过分组网络传输的TDM帧的压缩方法。该方法基于分配的TDM时隙的映射，但不是所有未分配的时隙到传输结构中，从而减少了在分组上传输的所需数据量，从而在TDM帧的传输期间降低了所需的分组速率和分组容量。该映射还被布置为允许分组速率和分组容量的动态改变，因此执行映射，使得允许传输TDM帧的工作大小随时间增加或减少。此外，提供了用于降低低速率信号经验延迟的机制。

摘要： There is provided a method and corresponding node and system for playout buffering and retransmission which can handle Over-The-Top (OTT) and Video-On-Demand (VOD) distribution to a large number of client devices, e.g. a server serving a number of client devices with e.g. the same TV-channel. The presented method comprises transmitting a data stream DS from a server 101 to at least two client devices 151 - 153, where a predetermined portion of client shared data of the data stream is buffered in a shared buffer. Upon receiving per client requests for retransmission of data from the client devices, requested data is retrieved from the shared buffer and retransmitted to the requesting client device. The method further comprises removing buffered data from said shared buffer based on if a time of interest for the buffered data has passed. The inventive concept is applicable in distribution of e.g. media data as in typical OTT and VOD, which is transported over unicast. Optionally, media data is distributed over multicast but with per client requests for retransmissions.

摘要： There is provided a method in a communication network system (100) of e.g. IP type for live distribution of media content capable of node-to-node time-transfer for synchronizing a respective local clock of an originating server (101) and at least one client device or other server (151, 152, 153) by means of two-way time transfer. The media content is sent as a data stream DS X using unicast or multicast via respective communication links over a network (200). The method comprises employing a mode in which two-way time transfer is selectively provided, selectively meaning that two-way time transfer is employed such that the amount of per client specific time information T sx , T xs being exchanged by the server and client devices is controlled, e.g. by time limiting the two-way time transfer, or during that mode reducing the occurrence of full two-way time transfer based synchronization of the client devices.

摘要： There is provided a method for adaptive bitrate (ABR) adjustments in an IP network before making upshift of ABR level of media streams like video for live Over the Top (OTT) distribution. The invention is based on before upshifting of a current ABR level to a higher ABR level for one or more client devices, probing the network system with a higher bitrate of the data stream provided by e.g. replicating data in the data stream, and monitoring network conditions during probing. Based on the probing it is determined if the available resources in the network are sufficient to sustain an upshift of ABR-level for the client device.
