Abstract: Embodiments for dynamically resizing buffers for a slab allocator process are described. The slab allocator informs the consumer that the memory buffer must be shrunk to a smaller size. A buffer allocation process dynamically reclaims portions of larger memory buffers to make room for a smaller allocation by shrinking data objects in larger slabs and returning slabs to reserve or free slab lists. Initially a large limit is set, and it is dynamically reduced once all the available memory is exhausted. This allows the slab allocator to adapt to the workload.

This functionality can be used to route packets in a BIER environment.

Abstract: Time stamp replication within wireless networks is described. In an embodiment, a wireless station receives an input time stamp and uses this input time stamp to generate an output time stamp. The wireless station transmits the output time stamp to wireless stations in one of a number of groups which make up the wireless network. The output time stamp is generated to compensate for delays between receiving the input time stamp and transmitting the output time stamp such that output time stamp which is transmitted at a time T corresponds to the value that the input time stamp would have had if it had been received at time T (and not at a time earlier than T). This may, therefore, reduce or eliminate independent time stamp errors and jitter caused by multiple disparate systems and processes.

The method comprises a first mode not using any return information from the receiver, executed at the start of the transmission, where the only possible modification to the transmission rate by the sender is an increase, and at least one second mode implemented following the first mode using at least one item of return information from the receiver.

The transmission rate is shared between a useful-data rate budget comprising the audio/video data and a secondary-data rate budget not necessary for the decoding of the audio/video data. The secondary budget is used for exploring the capacities of a network link.
