Embodiments of this application disclose a method and an apparatus for adjusting a packet transmission rate, to alleviate network congestion and reduce a packet transmission delay. The method includes: a first device obtains a target rate and address information of a destination end, where the target rate is lower than bandwidth at a source end; and the first device sends a correspondence to a second device configured to adjust the packet transmission rate, where the correspondence includes the target rate and the address information of the destination end.

Methods, systems, and apparatuses for scheduling a plurality of Virtual Links (VLs) in a Time-Triggered Ethernet (TTE) network by determining a subset of a group of bins allocated to TT traffic; restricting the subset bin groups to a specified harmonic subdivided pattern with a certain duration; allocating the subset of bin groups in accordance with bin group equated with a rate at least twice as high as a highest TT traffic rate available in the network to enable control of partitioned traffic by using a set of media reservations; checking whether a bin selected via a bin selection process for scheduling a TT Virtual Link (VL) is a valid TT bin, else proceeding to a subsequent bin until a valid TT bin is returned for the TT VL, and reserving using at least one media reservation for a TT VL to be scheduled by temporal partitioning at the restricted rate.

The disclosure relates to an Edge Cloud Platform (ECP) and a method executed in the ECP, for providing a low-latency, distributed, multi-user application. The method comprises determining a first location of a first group of users requesting access to the multi-user application and deploying the multi-user application in a first Point of Presence (PoP) in a first Service Provider (SP) domain operative to serve the first group of users. The method comprises determining a second location of a second group of users requesting access to the multi-user application and deploying a proxy of the multi-user application in a second PoP in a second SP domain operative to serve the second group of users. The method comprises, upon determining that a Software License Agreement (SLA) exists between the first and second SPs, establishing a tunnel for linking the multi-user application and the proxy of the multi-user application, thereby providing the low-latency.

An interface may be provided between i) a selective forwarding unit (SFU) configured to, in real-time, receive a data stream from a sender via a first network link of a communication network and selectively forward the data stream to one or more receivers via respective second network links, and ii) one or more core network functions (PCF, PCRF, NSMF, CSMF) for establishing service guarantees for data flows in the communication network. In a specific example, the interface may be established as a network function (SMGF) which translates streaming requirements for one-to-many flows coming from WebRTC SFUs into appropriate QoS/network slice configurations, such that the quality of RTC flows may be increased. Accordingly, negative side-effects of conservative congestion control algorithms in WebRTC clients and static/overprovisioned QoS at network operators may be overcome.

The controller (10) acquires information about the band of the flow within the tunnel and the band of each flow after policing or shaping, calculates the ratio of the traffic volume after policing or shaping to the traffic volume before policing or shaping by using the acquired information about the band, and estimates the traffic volume of the flow to be monitored within the tunnel by using the calculated ratio and the band of each flow after policing or shaping.

A system for forwarding packets between a first endpoint and a second endpoint, comprising one or more processors; a first network interface for communication with the first endpoint and a second network interface for communication with the second endpoint; and non-transitory memory comprising instructions. The instructions cause the one or more processors to receive a first packet from the first endpoint comprising a first data payload; generate a second packet, comprising the first data payload and an indicator of remaining buffer capacity different from an actual buffer capacity of the system; transmit the second packet to the second endpoint; receive a third packet from the second endpoint comprising a second data payload; generate a fourth packet, comprising the second data payload and an indicator of remaining buffer capacity different from an actual buffer capacity of the system; and transmit the fourth packet to the first endpoint.

Described embodiments include a system that includes a network interface and a processor. The processor is configured to identify, via the network interface, a state of congestion in a communication channel between a base station belonging to a cellular network and a client device, to calculate, responsively to the state of congestion, a maximum sustainable encoding bit rate (MSEBR) for a video that is being downloaded by the client device, from a server, via the communication channel, the video being encoded at a plurality of different predefined bit rates, and to inhibit the client device, in response to calculating the MSEBR, from downloading a segment of the video that is encoded at any one of the predefined bit rates that exceeds the MSEBR. Other embodiments are also described.

A communication control apparatus includes an observed data rate acquiring unit configured to acquire observed data rates indicating input data rates of queues, the observed data rates being observed in a layer 2 switch, a threshold value storage unit configured to store predetermined threshold values of the queues, a shaping rate determination unit configured to determine a shaping rate of each queue based on both observed data based on an observed data rate of the observed data rates acquired by the observed data rate acquiring unit and a threshold value of the predetermined threshold values stored in the threshold value storage unit, and a shaping rate setting unit configured to set, in the layer 2 switch, the shaping rate of each queue determined by the shaping rate determination unit.

Various embodiments are directed to techniques for dynamically adjusting a maximum rate of throughput for accessing data stored within a volume of storage space of a storage cluster system based on the amount of that data that is stored within that volume. An apparatus includes an access component to monitor an amount of client data stored within a volume defined within a storage device coupled to a first node, and to perform a data access command received from a client device via a network to alter the client data stored within the volume; and a policy component to limit a rate of throughput at which at least the client data within the volume is exchanged as part of performance of the data access command to a maximum rate of throughput, and to calculate the maximum rate of throughput based on the stored amount.
