Edge node control

Abstract

There is provided a method for providing edge node 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 by analyzing at least one data stream characteristics of a corresponding received data stream of the one or more receiving client devices 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 based on applying adaptive bitrate, ABR, to maintain highest achievable performance when it comes to video quality and also affect on other services, are provided.

         16 . A method of adaptively transmitting a data stream over an IP, Internet Protocol, network to a plurality of client devices comprising:
 for at least one respective outgoing data stream being transmitted to a respective client device
 analyzing at least one data stream characteristics of a corresponding received data stream of at least one of said respective client devices; and 
   providing a transmission strategy by applying a selected adaptive bit rate, ABR, level per client device for said at least one respective outgoing data stream based on said analyzed data stream characteristics.   
     
     
         17 . A method according to  claim 16 , wherein said transmission strategy is coordinated for said plurality of client devices. 
     
     
         18 . A method according to  claim 16 , wherein said selected ABR level is selected from a set of bitrates, ABR, levels of said outgoing data stream. 
     
     
         19 . A method according to  claim 16 , wherein said transmission strategy is further based on at least one system characteristics. 
     
     
         20 . A method according to  claim 16 , further comprising determining said system characteristics. 
     
     
         21 . A method according to  claim 19 , wherein said system characteristics is one of access technology type, network type, and device capability. 
     
     
         22 . A method according to  claim 16 , wherein said transmission strategy is provided by selecting a control scheme from a set of predetermined control schemes. 
     
     
         23 . A method according to  claim 16 , wherein said step of analyzing is performed on a plurality of outgoing data streams associated with a plurality of nodes or a group of client devices. 
     
     
         24 . A method according to  claim 16 , further comprising identifying groups of client devices utilizing at least one common network resource. 
     
     
         25 . A method according to  claim 16 , further comprising identifying if a single client device is utilizing a specific base station/network resource. 
     
     
         26 . A method according to  claim 23 , wherein said group of client devices are connected to an aggregation network. 
     
     
         27 . A method according to  claim 23 , wherein said group of client devices are handled by a common controller or edge server. 
     
     
         28 . A method according to  claim 16 , wherein said predetermined data stream characteristics is at least one of packet loss patterns, and change in delays, of the received data stream. 
     
     
         29 . A node in a communication network comprising means for performing a method according to  claim 16 .
