摘要： A method for protecting the head node of a Point to Multipoint Label Switched Path (P2MP LSP) includes: a Backup Head Node (BHN) establishes a backup LSP from the BHN to all Merge Points (MPs), where the backup LSP bypasses a Master Head Node (MHN); the MHN forwards data along an LSP already established between the MHN and the MPs; when a head node switchover condition is met, the BHN is switched to a master mode to forward data along the backup LSP established between the BHN and the MPs. A system and apparatus for protecting the head node are also provided. With the head node protection solution provided by the present disclosure, the head node is well protected and the protection mechanisms for the P2MP LSP are therefore more complete. This can further promote the scale deployment of P2MP systems.

摘要： In general, the invention is directed to techniques for scheduling resource access within an intermediate network device. For example, as described herein, a device receives packets for a plurality of sessions that include application-layer data for the sessions. The device determines a weight for each of the plurality of sessions and, during periods of resource congestion, selects one or more sessions for additional resource allocation based on the respective weights of the sessions. The device allocates additional memory resources to selected sessions to enable further buffering of application-layer data such that the device may apply the service to multiple sessions concurrently despite the resource congestion.

摘要： A magnetic tunneling junction (MTJ) in an MRAM array is disclosed with a composite free layer having a FL1/FL2/FL3 configuration where FL1 and FL2 are crystalline magnetic layers and FL3 is an amorphous NiFeX layer for improved bit switching performance. FL1 layer is CoFe which affords a high magnetoresistive (MR) ratio when forming an interface with a MgO tunnel barrier. FL2 is Fe to improve switching performance. NiFeX thickness where X is Hf is preferably between 20 to 40 Angstroms to substantially reduce bit line switching current and number of shorted bits. Annealing at 330° C. to 360° C. provides a high MR ratio of 190%. Furthermore, low Hc and Hk are simultaneously achieved with improved bit switching performance and fewer shorts without compromising other MTJ properties such as MR ratio. As a result of high MR ratio and lower bit-to-bit resistance variation, higher reading margin is realized.
