摘要:
A method for link aggregation of a plurality of communication links, performed in a communication arrangement, the method comprising; obtaining a data segment (210) to be transmitted, identifying a preferred communication link out of the plurality of communication links for transmission of the data segment, and, if the preferred communication link is not available for transmission of the data segment within a current time period, identifying an alternative communication link out of the plurality of communication links different from the preferred communication link, fragmenting the data segment (210) into at least a first fragment (210a) and a second fragment (210b), attaching a fragment header (220, 230) to each of the first and second fragments, each fragment header being configured to identify the respective fragment as a fragment belonging to a data segment, and transmitting the first fragment (210a) over the alternative communication link.

Notifications are received about flowlets originating or received at the endpoints. In response to the received notifications, updated flow rates are computed for the flowlets. The updated flow rates are sent to devices for use in controlling flow rates for the fiowlets in accordance with the computed updated flow rates. A device controls a rate of communication on a link of the network based on the received communication rate. A modified Newton like process is applied to optimize current flow rates at respective devices based on information about flowlets.

摘要:
Methods, system, and apparatuses may support end-to-end (E2E) quality of service (QoS) through the use of service layer (SL) sessions. For example, an application can communicate with a targeted device based on application specified schedule, latency, jitter, error rate, throughput, level of security, and cost requirements. Exemplary system 150 supports mechanisms to manage QoS in an end-to-end fashion. System 150 supports use cases that require application 156 to specify on-demand E2E QoS requirements. On-demand E2E QoS requirements may include reachability schedule (e.g., when the application requires that a targeted M2M/IoT device be reachable to service its SL requests), E2E latency, E2E throughput, E2E jitter, E2E error rate, E2E security level, or E2E cost of communication, among other things. System 150 includes Internet of Things (IoT) servers (e.g., IoT server 152), IoT gateways (e.g., IoT gateway 151), and devices (e.g., IoT field device 153 or IoT device 154) interconnected to one another via a diverse combination of local area and wide area underlying networks (e.g., 3GPP 161, broadband Ethernet 162, Wi-Fi 163, or 6LoWPAN 164). Hosted on the servers and gateways are instances of IoT SLs (e.g., IoT SL 166 or IoT SL 165). Hosted on the devices in the field as well as the devices in the backend are IoT applications (e.g., IoT device application 155 and IoT application 156) that communicate with one another. For example, E2E communication between a patient's IoT sensor or actuator and a backend patient monitoring application. System 150 further includes a service layer connection manager (SLCM) function (e.g., SLCM 157 or SLCM 158), an application connection manager (ACM) function (e.g., ACM 159 or ACM 160) and an underlying network connection manager (UNCM) function (e.g., UNCM 167, UNCM 168, or UNCM 169). Together the SLCM, ACM, and UNCM functions interact with one another to more intelligently manage and configure the end-to-end underlying network QoS and connectivity of IoT devices, gateways, servers, and applications in support of E2E QoS.

A radio network node (110), e.g. an Access Point, and wireless devices (120- 1..120-K) are comprised in a Wireless Local Area Network (100). The radio network node is configured to: Identify (201; 301-302; 501) wireless devices (120-1..120-K) associated with common properties of one or more predetermined property types. Obtain (202; 303; 02) data intended for transmission to the identified wireless devices (120-1..120-K), where different parts of the data is intended for transmission to different wireless devices. Form (203; 303; 503) a single data packet based on said common properties and comprising the obtained data. The single data packet is associated with a packet type directed to deliver data to only a single wireless device. Transmit (204; 304; 504) the single data packet on a communication channel being accessed by all of the identified wireless devices (120-1..120-K).

More specifically, methods may include transmitting one or more trigger frames from an access point to one or more communication stations, the one or more trigger frames comprising a plurality of components, the plurality of components indicating whether trigger frames within a beacon interval are scheduled in a periodic or aperiodic manner, and if periodic trigger frames are scheduled, then indicating a countdown to the next trigger frame, and if aperiodic trigger frames are scheduled, then indicating the time to the next trigger frame scheduled by the access point. Methods, apparatus, and systems described herein can be applied to 802.1 lax or any other wireless standard.
