BASE STATION, TERMINAL, AND COMMUNICATION METHOD

Thu, 06 Apr 2017 08:00:00 EDT

Even when a terminal goes out of a macro cell, data communication in the small cell can be caused to continue while the mobile management in a macro cell is continued. When a first determination unit (205) determines that a terminal exists outside the cell of a base station (200), an existence recognition packet transmission/reception unit (207) transmits a recognition packet, which is used for recognition, to the terminal via a small cell, and thereafter receives a response to the recognition packet from the terminal via the small cell. When a second determination unit (206) determines, because of the reception of the response, that the terminal exits inside the cell of the base station (200), a radio resource control unit (204) causes the connection of the control plane between the terminal and the base station (200) to continue.

The subheader field includes a sequence number field which notifies a sequence number; a more fragment field which notifies whether or not the data is a last fragment; and a frame body length field which notifies a length of the frame body field. A receiver receives, from the external device, a response frame notifying a successively and successfully received maximum sequence number which indicates a highest sequence number among sequence numbers indicated in sequence number fields of frame sets which have been successively and successfully received by the external device among the n frame sets included in the transmitted frame. The receiver receives one response frame per transmitted frame, even if more than two frame sets among the n frame sets have been successfully received.



LINK ADAPTATION FOR 802.11 SYSTEM

Thu, 06 Apr 2017 08:00:00 EDT

A method implemented by a first network device in a Wireless Local Area Network (WLAN) to provide Modulation Coding Scheme (MCS) feedback. The method includes selecting an MCS that is determined to have a highest data rate among a plurality of available MCSes that when used to transmit a frame having a reference payload size over a wireless communications link between the first network device and a second network device results in a frame error rate that is less than or equal to a threshold error rate for a given set of transmission properties, generating a frame having a Media Access Control (MAC) header, wherein a control field of the MAC header includes an indication of the selected MCS, and transmitting the generated frame to the second network device through a wireless medium.



DETERMINING NETWORK RANK FOR COMMUNICATION TO NEIGHBORING NODES

Thu, 06 Apr 2017 08:00:00 EDT

The determination and advertisement of a node's rank in an RF mesh network reflects sustained network changes. A node's advertised rank may be based on the node's induced rank and a previous rank candidate. Induced rank is the rank of the node at a particular point in time. Rank candidate is based on a running average of the node's past rank. The advertised rank may be based on a weighted sum of the induced rank and a previous rank candidate. Induced rank may consider a Link Quality Indicator (LQI), which may be based on a running average LQI.



Control Device, System, and Transmission Channel Adjustment Method in Software-Defined Networking

Thu, 06 Apr 2017 08:00:00 EDT

A control device, a system, and a transmission channel adjustment method in software-defined networking (SDN) where, a connection status of a control channel is acquired, it is determined, according to a preset threshold, whether a standby channel is suitable to continue serving as a standby channel. The standby channel is adjusted when the standby channel is congested to a specific extent and another uncongested channel is set as the standby channel, and the standby channel is switched to an active channel when the active channel is congested such that real-time channel adjustment is ensured, effective transmission of control information is ensured, and control reliability of a control device in SDN is improved.



Method For Establishing Hard Pipe in Network, And Method And Apparatus for Forwarding Packet in Network

Thu, 06 Apr 2017 08:00:00 EDT

The present disclosure discloses a method and apparatus for establishing a hard pipe in a network. The network includes multiple routers and a network management system. The method includes: acquiring, by the network management system, bandwidths of a plurality of links in the network; instructing, a router to allocate a fixed bandwidth from a bandwidth of the link of the network topology, where a link to which the fixed bandwidth is allocated forms a sublink, and the sublink and the router that allocates the sublink form a hard pipe stratum, which is used to carry a leased line service; and allocating, a static MPLS label set to the hard pipe stratum. A service packet that has an MPLS label in the static MPLS label set is forwarded by using the hard pipe stratum, thereby ensuring that a bandwidth of the leased line service is not occupied by a non-leased line service.



LINK AGGREGATION GROUP (LAG) SUPPORT ON A SOFTWARE-DEFINED NETWORK (SDN)

Thu, 06 Apr 2017 08:00:00 EDT

In one embodiment, a system includes a software-defined network (SDN) controller including a processor and logic executable by the processor. The logic is executable by the processor to receive a port addition indication that a logical port is configured on a switching device, the switching device being coupled to the SDN controller and a second device, with the logical port representing a link aggregation group (LAG) that includes at least two links between the switching device and the second device. The logic is also executable by the processor to derive and maintain a logical index for all logical ports in software-defined switching devices connected to the SDN controller based on logical port identifiers thereof. Other systems, methods, and computer program products are described in accordance with more embodiments.



NETWORK TRAFFIC SPLIT AMONG MULTIPLE PATHS

Thu, 06 Apr 2017 08:00:00 EDT

A transmitter includes a buffer programmed to queue packets and a computing device having a processor and a data storage medium. The computing device is programmed to generate at least two sub-packets from each of the plurality of packets stored in the queue. For each sub-packet, the computing device is programmed to identify a plurality of transmission opportunities. Each transmission opportunity is associated with one of a plurality of networks. The computing device is further programmed to select among the plurality of transmission opportunities and transmit the sub-packet over the network associated with the selected transmission opportunity.



METHOD FOR CROSS-TRAFFICKING BETWEEN TWO SLAVES OF AN ANNULAR DATA NETWORK

Thu, 06 Apr 2017 08:00:00 EDT

In order to be able to maintain cross-traffic between slaves in a ring topology of an Ethernet-based data network even in the event of an error in the ring topology, which leads to the interruption of the ring topology, it is provided that in the event of the occurrence (rectification) of an error (F) in the annular data network (1), the ringmaster (RM) is configured to forward data packets or to block at least multicast data packets, and that the master (M) prompts the slaves (S1, S2), communicating with one another via cross-traffic, to transmit configuration data packets (DPMC1, DPMC2) as multicast data packets to each of the other slaves (S1, . . . , Sn) of the annular data network in order to adjust address tables (AT1, AT2) in the slaves (S1, S2), communicating with one another via cross-traffic.



PACKETIZED CONTENT DELIVERY APPARATUS AND METHODS

Thu, 06 Apr 2017 08:00:00 EDT

Apparatus and methods for delivery of content in a packetized network. In one embodiment, content and/or services can be associated with an IP address. The IP address may be assigned to multiple server devices disposed at geographically diverse locations. Delivery caches may advertise, via a routing protocol, one or more addresses to clients of the network. Route selection may be configured based on one or more rules such as geographical proximity, available bandwidth, server availability, server load, delivery cost, client subscription level, licensing rules, and/or other metric. Delivery caches may be configured to control their availability and/or load through IP address withdrawals and announcements. When the “closest” delivery cache may become unavailable (e.g., it is not announcing the IP address for the content the client is trying to obtain, a route to the next “closest” available delivery cache may be utilized.
