Embodiments of the present invention disclose a method for awaking an optical network unit in a passive optical network, including: receiving, by an optical line terminal OLT, a service packet corresponding to an ONU in an energy-saving mode, where the service packet carries a packet feature, and the packet feature indicates a service type of the service packet; detecting, by the OLT, the packet feature of the service packet; and when the packet feature of the service packet is a preset packet feature of needing to awake the ONU, awaking, by the OLT, the ONU in the energy-saving mode. According to the technical solutions provided in the embodiments of the present invention, an ONU can be awoken from an energy-saving mode in time when a traffic rate at an initial service stage is small, and a high QoS requirement of a service is met.

Method for awaking optical network unit in passive optical network, device, and system

A method, device and system for managing resources in networks are provided, which relate to the field of data communication. The method includes the following steps. A resource manager (RM) sends a first request message according to a received resource request message, to request an access node (AN) to perform admission control. After receiving an admission control result indicating whether a resource requested by the resource request message is admitted, the RM sends a response message of the resource request message. Therefore, when multicast/unicast connection admission control (CAC) that supports shared bandwidth is realized, flow fusions of user line configuration between the AN and a broadband remote access system (BRAS, and policy distribution between a resource and admission control subsystem (RACS) and the BRAS are guaranteed; and sharing of bandwidth resources is realized to avoid waste of the bandwidth resources.

Method, device and system for managing resources in networks

A message sending method is disclosed includes: receiving a message containing a plurality of requested programs, the plurality of requested programs being provided by a plurality of content service systems; separating the received message containing the plurality of requested programs into a plurality of sub-messages; and sending the separated plurality of sub-messages to corresponding ones of the plurality of content service systems. The invention also relates to a message sending device and a message transmission system.

Message sending method, message sending device and message transmission system

The present invention relates to the field of communications technologies, and discloses a method, an apparatus, and a system for allocating Internet Protocol Television (IPTV) resources to save bandwidth resources in the IPTV service. The method includes the following: a multicast access control entity allocates resources to a unicast access control entity through an intermediate network entity when unicast resources are not enough; and the unicast access control entity allocates resources to the multicast access control entity through the intermediate network entity when multicast resources are not enough. The present invention is primarily applicable to IPTV technologies.
