The mapping and encapsulating unit implements conversion between a channel layer TDM signal from the TDM three-direction cross unit and packet service signals from the packet processing unit. | 10-25-2012 |
20130129353 | Signal Transmission Processing Method and Apparatus and Distributed Base Station - The disclosures provide a method and apparatus for transmitting and receiving interface signals of a distributed base station. At least one channel of Common Public Radio Interface (CPRI) signals of a distributed base station are encapsulated into optical transport unit x (OTUx) signals in a frame structure of OTUx by adopting Generic Mapping Procedure (GMP) mapping scheme, wherein the x represents a transmission capacity and wherein the OTUx is adopted for providing a bandwidth required by the at least one channel of CPRI signals, and then the OTUx signals that bear the at least one channel of CPRI signals are sent. | 05-23-2013 |
20150023354 | METHOD AND DEVICE FOR ALLOCATING PACKET SWITCHING RESOURCE - Embodiments of the present invention provide a method and a device for allocating a packet switching resource, which includes: receiving, by a management plane unit, a service transport request carrying service information, where the service information includes source node information, sink node information, quality of service QoS requirement information, and bandwidth requirement information; determining, by the management plane unit, at least one transport path according to the service information and a preset resource allocation policy, and generating a routing table entry/forwarding table entry according to the at least one transport path; and sending, by the management plane unit, the routing table entry/forwarding table entry to data plane units of packet switching devices of each transport path of the at least one transport path. According to the embodiments, transparent and controllable allocation of a network bandwidth resource is implemented, so that utilization efficiency of a network resource is improved. | 01-22-2015 |
