A wireless communication terminal includes a processor; and a non-transitory memory storing thereon a program which is executed by the processor, the program causing the processor to: transmit a first interest packet requesting transmission of an index of content to a plurality of communication devices via a content-oriented network; receive a first data packet from a first communication device among the plurality of communication devices in response to the first interest packet, wherein the first data packet includes i) the index and ii) first remaining battery level information indicating a remaining battery level of the first communication device, and determine to transmit to the first communication device a second interest packet requesting for transmission of the content to the wireless communication terminal when it is determined that the first remaining battery level information is more than a predetermined threshold value.

A method for managing congestion on a communication network that includes a network node having a congestion level. Congestion pre-emption criteria corresponding to the congestion level is determined. A list of potential service pre-emption candidates associated with a service pre-emption criteria that is at least equal to the congestion pre-emption criteria is created. The list of potential service pre-emption candidates is at least a sub-set of a plurality of services on the node. A determination is made as to whether to pre-empt at least one of the potential service pre-emption candidates on the list based at least on the service pre-emption criteria.

The invention is directed to systems, methods and computer program products for optimizing a configuration associated with a network. An exemplary method comprises: determining a node of the network is running a data session associated with an amount of data greater than a predetermined amount of data, and associated with a duration greater than a predetermined duration; configuring the network such that the node acts as an access point; and establishing a direct connection between the access point and a backbone of the network.

Method in and network node (700; 140a, 111a, 131a, 110a-c, 130a-c) of a wireless communications system (100a-c), for managing radio traffic load in a first cell (115a-c). The first cell (115a-c) is served by a first base station (110a-c) and is at least partly is covered by a second cell (135a-c) served by the first base station (110b) or a second base station (130a,c). Information is obtained (201, 601) about a future load of radio traffic in the first cell (115a-c). The future load is associated with a first group of wireless devices (120a-d) and generation of the future load is in response to an occurrence of a future event. It is then provided (202, 602), based on the obtained information, a change of serving cell so that at least one wireless device (121a) of a second group of one or more wireless devices (121a-b) being served in the first cell (115a-c) by the first base station (110a-c), instead become served in the second cell (135a-c).

A hardware-implemented rate limiter is described. This implementation guarantees that messages containing a value v are not forwarded at a higher rate than a predefined threshold value r. More specifically, given a number of times x in a time interval y, which specifies a rate r defined by x/y, the rate limiter reports a violation by selectively setting an error value when v occurs more than x times during the time interval y. Moreover, the rate limiter may be able to keep track of multiple predefined threshold values for different rates. Furthermore, the rate limiter may keep track of 2.sup.b different values v, where b is the number of digits of the binary representation of v.

A packet processing method, the method includes, receiving TCP packets from a wireless access point. An A-MSDU packet is created by aggregating TCP ACK frames generated by the received TCP packets. When the current data transmission speed is less than or equal to a first threshold value and timeout for the A-MSDU packet sent to the wireless access point continuously occurs over a first predefined time, a transmission time interval is reduced by the first preset value and the packet size value is re-calculated according to the adjusted transmission time interval. When the current data transmission speed is greater than or equal to the second threshold value and the size of the created A-MSDU packet that achieves the packet size value occurs over a second predefined time, the packet size value is increased by the second preset value.

Systems, methods, and apparatuses provide a scalable framework for analyzing queuing and transient congestion in network switches. The system reports which flows contributed to the queue buildup and enables direct per-packet action in the data plane to prevent transient congestion. The system may be configured to analyze queuing in legacy network switches.

The present disclosure describes techniques of processing burst traffic. In the present application, when a service request is received, it is determined whether there is service data corresponding to the service request in a buffer unit. If so, the corresponding service data in the buffer unit is directly sent to a client computer so as to reduce access pressure of a second service layer; if not, determining whether a request frequency associated with the service request is greater than a frequency threshold; when the request frequency of the service request is greater than the frequency threshold, it indicates that the second service layer of the service type corresponding to the service request reaches the upper limit of capacity. In this case, the service request is sent to a first service layer so as to acquire corresponding service data.

A method for synchronizing multicast message subflows in a switched network includes associating, with a processing device, a first destination identifier corresponding to a multicast message with a first queue that corresponds to a first output port of a switching device, associating, with a processing device, a second destination identifier corresponding to the multicast message with a second queue that corresponds to a second output port of the switching device, pausing the first queue in response to a message counter corresponding to the first queue crossing a first predetermined threshold, and unpausing the first queue in response to the message counter crossing a second predetermined threshold, wherein the message counter indicates a quantity of data that has been forwarded by the first queue but remains to be forwarded by the second queue.

Generally, this disclosure describes techniques for buffer management based on link status. A host platform may include a Baseboard Management Controller (BMC) and a network controller that includes a buffer used by the BMC. When a network controller is in a lower power link state, the BMC may attempt to send data to the link partner which causes the network controller to transition out of the low power state. However, this transition may take longer than the buffer's ability to buffer the incoming flow from the BMC. Accordingly, to avoid the need for larger buffer space, a buffer manager is used to provide flow control management of the buffer based on link status.
