摘要： This disclosure provides a technique for hierarchical packet marking for Core-Stateless Active Queue Management (CSAQM). In particular, a network node measures the bitrate of each of a plurality of subflows that comprise a traffic aggregate (TA). The plurality of subflows in the TA belong to a single entity, and each subflow has a normalized weight value. The node modifies a random rate determination for a throughput-value function (TVF) associated with the TA based on the bitrates and weight of each subflow in the TA. Then, based on the modified rate, the node calculates a packet value (PV) with which to mark a packet in a given subflow, and marks the packet with the PV. Marking packets according to the techniques disclosed herein achieves a desired weighted resource sharing, and ensures that the random rates are uniformly distributed for the entire TA.

摘要： Systems and methods of the present disclosure are directed to a method performed by a receiving node. The method includes receiving a packet/frame comprising Per Packet Value (PPV) information from a transmitting node, wherein the PPV information indicates a level of importance of the packet/frame determined 5 based on a marking policy of the transmitting node, and wherein the packet/frame comprises (a) an Ethernet packet, (b) an IPv4 packet, (c) an IPv6 packet, (d) a Multi-Protocol Label Switching (MPLS) packet, or (e) a multilayer packet descriptive of one or more of (a)-(d). The method includes processing the PPV information in the received packet/frame when the receiving node is configured to handle the PPV information.

摘要： A method and a first network node (110) of a first network (101) for handling packets from a second network node (120) of a second network (102) are disclosed. The first network node (110) manages a plurality of Drop Precedence levels for indicating precedence relating to dropping of packets, wherein each DP level is associated with a respective set of token buckets, wherein each token bucket of the respective set of token buckets for said each DP level is associated with a respective time scale. The first network node (110) receives (A030) a packet from the second network node (120). The first network node (110) further marks (A050) the packet with a least DP level for which each token bucket associated with said least DP level includes a respective number of tokens that is greater than or equal to a size of the received packet. A corresponding computer program (1003) and a computer program carrier (1005) are also disclosed.

摘要： A method of controlling the rate of traffic flow through an Iub interface of a Radio Network Controller is described. The method includes obtaining a licensed rate, which defines the maximum throughput permitted through the Iub interface, at the Radio Network Controller. The rate of traffic flow through the Iub interface and all Iu interfaces of the Radio Network Controller is measured, and the extent to which packet switched traffic flow through the Iub interface exceeds the licensed rate identified. If the packet switched traffic flow through the Iub interface exceeds the licensed rate, packets are dropped from traffic flow through the Iub interface to reduce the traffic flow to the licensed rate.

摘要： A computing device (110) receives a packet comprised in a flow, and uses a region index table (310) to identify a first region of a Throughput-Value Function, TVF (400), based on a flow rate of the flow. The first region is one of a plurality of sequentially ordered regions across an input domain of the TVF (400). The computing device (110) randomly selects one of a plurality of preconfigured offset values to identify a second region of the TVF (400) that is lower than the first region of the TVF (400) by the randomly selected offset value. The computing device (110) determines a packet value using a TVF table (330) that maps each of the regions to a respective one of a plurality of packet values. The packet value is mapped to the second region. The computing device (110) marks the packet with the packet value mapped to the second region.

摘要： An intermediate device (110) of a communication network (100) assigns each of a plurality of received packets (300) to either a Low Latency, Low Loss, Scalable throughput (L4S) queue (370a) or a non-L4S queue (370b). Each queue (370a, 370b) is associated with one packet value size counter for each of the plurality of packet values (320). The intermediate device (110) increments, for each packet (300) and by a size of the packet (300), the packet value size counter associated with the queue (370a, 370b) to which the packet (300) is assigned and calculates, for each queue (370a, 370b), a congestion threshold value based on the packet value size counters associated with the queue (370a, 370b). The intermediate device (110) marks one or more of the packets (300) as having experienced congestion based on the congestion threshold values of the queues (370a, 370b).

摘要： A system, method, node and computer program for transfer of downlink data packets from a server (120) to a client (100) across at least one first data packet transport domain (130) and at least one second data packet transport domain (140) is disclosed. The two data packet transport domains (130, 140) have different transport characteristics and are interconnected via at least one proxy (110). The server (120) is located in front of the first data packet transport domain (130) and the client (100) is located behind the second data packet transport domain (140). The method comprises sending, by the server (120), a data packet to the client (100) and sending, by the proxy (110), responsive to the reception of the data packet, an acknowledgement to the server (120) acknowledging the reception of the data packet or a failure to receive the data packet at the proxy (110). The method further comprises forwarding, by the proxy (110), the received data packet to the client (100) and deleting, by the proxy (110), after sending of the acknowledgement to the server (120) and forwarding the received data packet to the client (100), the received data packet in the proxy (110) and determining, by the server (120), a delivery status of the data packet or a failure location in either of the two data packet transport domains (130, 140) based on acknowledgements received from the client (100) and/or the proxy (110).
