  • Patent number: 10944514
    Abstract: A technique for transferring data in a radio communication is described. As to one method aspect of the technique, the data is received in at least two hybrid automatic repeat request (HARQ) processes (580, 582). For each of the at least two HARQ processes (580, 582), an error detection scheme is performed for the received data. For each of the at least two HARQ processes (580, 582), a feedback (596, 598) is sent based on a logical combination (589) of results (585, 587) of the error detection scheme for the at least two HARQ processes (580, 582).

  • Patent number: 10931799
    Abstract: An apparatus for handling resets corresponding to multiple reset domains comprises a transport network interconnecting elements to enable data to be transferred from one element to another, ingress circuitry to couple elements to the transport network, and egress circuitry to couple the transport network to the elements. The ingress circuitry couples source elements to the transport network, and is responsive to receiving data from a source element to generate at least one transport packet in order to send that data over the transport network. Each transport packet comprises a reset domain indicator indicative of the reset domain in which the source element operates. The egress circuitry couples the transport network to destination elements and, whilst a reset of a particular reset domain is asserted, discards transport packets for which the reset domain indicator indicates the particular reset domain.

  • Patent number: 10917346
    Abstract: Techniques for implementing resilient hashing with compression are provided. In some embodiments, a network device can maintain a compressed partition and an uncompressed partition for a logical hash table, where the logical hash table comprises a first set of mappings between bucket identifiers and active next-hop destinations, the compressed partition comprises a second set of mappings between compressed indices and the active next-hop destinations, and the uncompressed partition comprises a third set of mappings between uncompressed indices and the active next-hop destinations. The network device can compute a hash value using a portion of a packet. When the hash value is addressed by a compressed index, the packet is sent to a next-hop destination in the compressed partition. When the hash value is addressed by an uncompressed index, the packet is sent to a next-hop destination in the uncompressed partition.

  • Patent number: 10892991
    Abstract: Techniques for implementing resilient hashing with multiple hashes are provided. In one set of embodiments, a network device can maintain a first hash table comprising mappings between a first set of hash indices and a set of bit values. The network device can also maintain a second hash table comprising mappings between a second set of hash indices and active next-hop destinations. Upon receiving a network packet, the network device can compute a first hash and can match the first hash value to a first mapping in the first hash table based on the first mapping's hash index. When the first mapping's bit value indicates that the first mapping's hash index corresponds to an active next-hop destination, the network device can further match the first hash value to a second mapping in the second hash table and send the network packet to the second mapping's active next-hop destination.

  • Patent number: 10868748
    Abstract: A source network device can inject a probe into any one of multiple pipelines by supplying control bits for controlling a demultiplexer through which the probe passes. The control bits of the probe are coupled to the demultiplexer select lines so as to couple an input port of the demultiplexer to one of multiple output ports. As a result, an agent operating on the source network device can test any desired pipeline. In a one-hop embodiment, the source network device redirects the probe back to the agent without transmission to a neighbor. A two-hop embodiment uses a neighbor device to reflect the probe back to the source device in order to test forwarding states of the source network device.

  • Patent number: 10820217
    Abstract: The invention describes a method for handling of cell identities, performed by a first radio node of a wireless communication network providing radio coverage to a first cell. The first radio node is connected to at least one second radio node providing radio coverage to a second cell. The first cell has been assigned a first cell identity, and each of the second cells has been assigned an individual cell identity. The method comprises: determining that the first cell identity is the same as the cell identity assigned to one of the second cells; triggering change of cell identity for the first cell from the first cell identity to a second cell identity that is not used for any of the second cells, and sending, to the at least one second radio node, information on the change of cell identity from the first cell identity to the second cell identity.
