A remote management system for Customer premises equipment WAN Management Protocol (CWMP) is provided. The remote management system includes at least one CPE (Customer Premises Equipment) and one server coupled to the CPE via a network. The CPE transmits a request to the server via the network. The server processes the request from the CPE according to a processing order, wherein the server provides a table which contains forecasted processing times for commands of a plurality of data models compatible with the CWMP. Upon receiving the request, the server generates a command configuration document according to the request, forecasts and obtains a first processing time corresponding to the command configuration document, and then dynamically adjusts and arranges the processing order for processing the request in the server according to the first processing time and a maximum waiting time corresponding to the request.

Remote management systems and apparatuses for CWMP and methods for improving performance of remote management thereof

A master device, a slave device, and methods are disclosed. The method is performed by a first slave device connected to a master-slave tree network, comprising: determining whether a beacon has not been received within a predetermined time period; and distributing a first beacon to a second slave device if no beacon has been received within the predetermined time period; wherein for the first slave device to remain in the master-slave-network, a beacon be received by the first slave device within the predetermined time period.

Master device, slave device, and methods thereof

A method for managing periodic packets, a server and a network equipment are provided. The method includes the steps of receiving at least one transmission parameter of a plurality of periodic packets, determining at least one time sequence for rearranging and transmitting the periodic packets according to the at least one transmission parameter, transmitting the at least one time sequence, and receiving and disassembling the periodic packets already rearranged and transmitted according to the at least one time sequence.

Method for managing periodic packets, server and network equipment

A system and a method for transmitting network packets are provided. The system includes an information module, a scheduling module, and a forwarding module. The information module receives and records media information of a plurality of multimedia streams. The scheduling module calculates a guaranteed bit rate of each multimedia stream according to the media information provided by the information module, and rearranges isochronous packets of the multimedia streams in the first time slots of a plurality of clock cycles according to the guaranteed bit rates so that the transmission of the isochronous packets satisfies the guaranteed bit rates. The length of each clock cycle is a predetermined length. The length of the first time slot and the predetermined length are in a predetermined ratio. The forwarding module transmits all the packets of a clock cycle to a network at every a time interval of the predetermined length.

System and method for transmitting network packets adapted for multimedia streams

A distributed audio visual (AV) system including a plurality of media servers, a media renderer, and a control point which are connected to each other via a peer-to-peer network is provided. Each of the media servers includes a content directory management unit (CDMU) and a query content information (QCI) module, wherein the CDMU includes a synchronizer module and a content information maintainer (CIM) module. The synchronizer module synchronizes content information of AV contents stored in all the media servers. The CIM module records the content information and establishes an integrated content directory list according to the content information. The QCI module queries the content information. The control point obtains the integrated content directory list from one of the media servers and queries the content information related to all the AV contents, so as to control the media renderer to play the AV contents.

Distributed audio visual system and content directory management system and method thereof

Disclosed is a packet forwarding apparatus and method for a virtualization switch, applicable to switch environments built by Internet Small Computer System Interface (iSCSI) connections. The packet forwarding apparatus comprises a header extractor, a dispatcher, and a forwarding unit. After completion of the authorization for iSCSI session connections, the header extractor receives iSCSI packets and extracts the headers for the iSCSI packets. The dispatcher decides the flow directions for the received packets. The forwarding unit forwards the packets between the client-side connection and the storage-side connection of the virtualization switch, including converting virtual addresses into physical addresses for the received iSCSI packets, building the mapping between the client-side interface and the storage-side interface, and delivering the payload associated with the connections.
