Abstract: In general, techniques are described for providing feedback loops for service engineered paths. A service node comprising an interface and a control unit may implement the techniques. The interface receives traffic via a path configured within a network to direct the traffic from an ingress network device of the path to the service node. The control unit applies one or more services to the traffic received via the path and generates service-specific information related to the application of the one or more services to the traffic. The interface then sends the service-specific information to at least one network device configured to forward the traffic via the path so that the at least one network device configured to forward the traffic via the path is able to adapt the path based on the service-specific information.

Abstract: A wireless communications system including a base station, a relay device, and a terminal device. The terminal device can transmit one or more first type access request messages to request uplink resources from the base station, and if no response to the first type access request messages is received from the base station, transmit a second type access request message. The base station is responsive to a first type access request message received from the terminal device to transmit an allocation of uplink resources to the terminal device. The relay device is responsive to a second type access request message received from the terminal device to transmit a relayed access request message to request the base station to allocate uplink resources to the terminal device. The base station is responsive to the relayed access request message to transmit an allocation of uplink resources to the terminal device.

Abstract: A routing system and method for flows within a network provides multicast flow transport for one or more groups. Transit routers comprising processing units that run overlay processes route one or more flows based on overlay group identifiers. Access nodes issue requests for overlay groups in order to receive flows from the transit routers. The overlay processes utilize a mapping service that maps overlay group identifiers to native multicast group identifiers. A control channel between the access nodes and transit routers is used for communicating access nodes requests, overlay group identifiers, and native multicast group identifiers.

Abstract: A method and apparatus manage a buffer of a lower network node in a communication system. A current queue length of the buffer is monitored in every measurement time. A logical region in which the current queue length is included is determined, among a plurality of logical regions included in the buffer. Each of the logical regions corresponds to a queue length determined by using an upper threshold and a lower threshold of a total queue length of the buffer. A congestion state of a network is detected, and a first queue length is readjusted when the current queue length is included in the first queue length which corresponds to a first logical region that exceeds the upper threshold. And a network congestion state signal that represents the detected congestion state of the network is transmitted to the upper network node.

Abstract: A method and system provide in-band protection switch signaling in a communication system arranged as a point-to-multipoint tree. The point-to-multipoint tree includes a root node communicatively coupled to a plurality of leaf nodes through both a working link and a protection link. Data is transferred through a current link of the point-to-multipoint tree. The current link is either the working link or the protection link. A fault is detected in the current link in the point-to-multipoint tree. Each leaf node in the point-to-multipoint tree is notified of the fault using the current link. Upon receiving the notification, the root node and each leaf node switch to the other link of the working link and the protection link.

Abstract: A unified frame structure for filter bank multi-carrier (FBMC) and orthogonal frequency division multiplexed (OFDM) waveforms may allow FBMC and OFDM frames to be communicated over a common channel without significant inter-frame gaps. The unified frame structure may set an FBMC frame duration to an integer multiple of an OFDM frame element duration to enable alignment of FBMC frames and OFDM frames in the time domain. The unified frame structure may also map control channels in the FBMC and OFDM frames to common resource locations so that the respective control channels are aligned in the time and/or frequency domains. The unified frame structure may also share synchronization channels between FBMC and OFDM frames. Additionally, overhead in an FBMC time division duplexed (TDD) communications channel can be reduced by overlapping time windows appended to FBMC blocks.

In one aspect, the selection between switching to a new transport mechanism and, adding a concurrent transport mechanism is based on an analysis and/or operator defined conditions.
