摘要:
In one embodiment, a first node as a source node obtains personal area network identifiers of the first node and a second node respectively; and then fills the personal area network identifiers of the first node and the second node and 6LoWPAN-message-type information in a 6LoWPAN data packet and sends them to the edge router. After receiving the 6LoWPAN data packet, the edge router judges 6LoWPAN-message-type information of the data packet. When the 6LoWPAN-message-type information indicates that the data packet is sent to another 6LoWPAN subnet, the 6LoWPAN data packet is encapsulated in an IP data packet and sent to a backbone network router. The backbone network router and the edge router of the subnet in which the destination node is located, respectively route the data packet according to the personal area network identifier of the destination address.

Regioselectively substituted cellulose esters having a plurality of aryl-acyl substituents and a plurality of alkyl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in optical films, such as optical films having certain Nz values, −A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.

An implantable device has an outer shell that includes an aperture through the housing of the device and, spanning the aperture, a membrane structure permeable to gas but not to liquid. In this way, excess gas may be vented from the device. The membrane and aperture are designed to discourage or even prevent tissue ingrowth.

A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server. A client device can be adapted to take advantage of the ingestion process. The client device might be configured to optimize use of resources, given the information available to it from the ingestion system. This may include configurations to determine the sequence, timing and construction of block requests based on monitoring buffer size and rate of change of buffer size, use of variable sized requests, mapping of block requests to underlying transport connections, flexible pipelining of requests, and/or use of whole file requests based on statistical considerations.

The present invention discloses a method for obtaining a service list and multimedia broadcast multicast service data, and the method includes: obtaining electronic service guide (ESG) information, receiving a system information block (SIB)13 from system information, and obtaining a cell service list according to the ESG information and the SIB 13. The present invention also discloses a system for obtaining a service list and multimedia broadcast multicast service data; in the system, a cell service list acquisition unit is configured to obtain ESG information, receive an SIB 13 from system information, and obtain a cell service list according to the ESG information and the SIB 13. With the method and system in the present invention, the cell service list can be acquired, and the receiving of data of multimedia broadcast multicast service (MBMS) service can be achieved after obtaining the cell service list.

摘要:
A method for scheduling communication traffic in an Advanced Telecom Computing Architecture based equipment and a corresponding apparatus are provided. In the method, communication traffic information of traffic processing means in the equipment is collected; based on the collected communication traffic information, a traffic distribution rule for the traffic processing means in next time period is generated; and based on the generated traffic distribution rule, incoming communication traffic of the equipment is scheduled. The method of the invention considers the quality of service and contracted capacity of the whole equipment and the dynamic processing capability and running environment of the traffic processing means, and can balance the loads of the respective traffic processing means in the equipment with asymmetric multi-application configuration well by adaptively adjusting the distribution of the communication traffic, to guarantee the quality of service of the whole equipment.
