Abstract: A user equipment (UE) receives and decodes a first erroneous transport block (TB) from a base station in a mobile communication network. The UE allocates a first soft buffer having a first buffer size. The first soft buffer is associated with a first HARQ process for storing the first TB. The UE then receives and decodes a second erroneous TB from the base station. The UE allocates a second soft buffer having a second buffer size. The second soft buffer is associated with a second HARQ process for storing the second TB. The UE releases a portion of the first soft buffer to be allocated as part of the second soft buffer. The dynamic buffer allocation method reduces mismatch between rate matching and soft buffer storing when the total number of HARQ processes is small. In addition, more HARQ processes can be supported when the corresponding TB size is small.

Abstract: Multi-destination frames in a network fabric may be carried in IP multicast packets. As such, the network fabric may us IP multicast technique such as a PIM protocol for handling the multi-destination frames. To provide redundancy, the system administrator can use phantom rendezvous points (RPs) that include multiple physical RPs where one of the RPs serves as a primary RP and the other RPs serve as secondary RPs (e.g., backup RPs). Instead of the system administrator manually configuring the phantom RPs, the RPs are automatically configured. To do so, the system administrator may use a GUI to provide multicast groups allocated for the multi-destination traffic, the number of desired phantom RPs (or physical RPs), and the desired RP redundancy. Based on these parameters, a data center manager generates one or more templates that automatically configure the network devices in the fabric as they are booted.

Abstract: A method is implemented for enforcing quality of service (QOS) for accessing content objects on a per user basis at a content centric networking (CCN) gateway in a CCN network. The method receives a CCN interest packet including a name for a content object from a user equipment. An expected size of the content object is determined. An estimated bandwidth usage for a user is calculated based on the expected size of the content object. The estimated bandwidth usage for the user is compared with a permitted bandwidth in a QOS profile of the user. The CCN interest packet is processed, in response to the estimated bandwidth being less than the permitted bandwidth in the QOS profile of the user.

Abstract: A method includes receiving a packet at an ingress node of a network. A hierarchical time stamp is created in the packet by the ingress node. The hierarchical time stamp includes an initial time stamp and an initial node identifier. The packet is passed to another network node, which adds a subsequent time stamp and a subsequent node identifier to the hierarchical time stamp. The packet is received at an egress node of the network. A final time stamp and a final node identifier are added to the hierarchical time stamp at the egress node. The hierarchical time stamp is then removed from the packet and the packet is passed to another network. The hierarchical time stamp is delivered to an analyzer.
