  • Patent number: 9847949
    Abstract: Examples disclosed herein relate to receiving, by a scheduler, a request for a window during which to send a data packet through a crossbar. Transmission of the data packet is dependent upon a pool of transmission credits. The scheduler determines whether the pool of transmission credits is sufficient for transmitting the data packet, and when it is determined that the pool of transmission credits is insufficient, the scheduler determines whether to block the request or to speculatively arbitrate the window based on a value of a speculative request counter.

  • Patent number: 9847943
    Abstract: A method is provided in one example embodiment and includes monitoring an egress port connected to a server to detect a traffic flow comprising a plurality of data packets and determining whether one of the packets is timeout dropped at the egress port. If at least one of the packets is timeout dropped at the egress port, the method further includes detecting a destination identifier (“DID”) of the timeout dropped packet and withdrawing a device identified by the detected DID from an FC zone to which it is assigned and reactivating the zone. The method further includes determining whether the traffic flow is experiencing high wait times at the egress port and, if the traffic flow is experiencing high wait times at the egress port, detecting the DID of the traffic flow and reducing a priority of the zone to which the detected DID is assigned and reactivating the zone.

  • Patent number: 9843508
    Abstract: Techniques are described for reusing downstream-assigned labels when establishing a new instance of a label switched path (LSP) prior to tearing down an existing instance of the LSP using make-before-break (MBB) procedures for RSVP. The techniques enable a routing engine of any non-ingress router along a path of the new LSP instance to reuse a previously allocated label for the existing LSP instance as the downstream assigned label for the new LSP instance when the paths of the existing LSP instance and the new LSP instance overlap. In this way, the non-ingress router does not need to update a label route in its forwarding plane for the reused label. When the new LSP instance completely overlaps the existing LSP instance, an ingress router of the LSP may avoid updating an ingress route in its forwarding plane for applications that use the LSP.

  • Patent number: 9781060
    Abstract: A crossbar switch has N input ports, M output ports, and a switching matrix with N×M crosspoints. In an embodiment, each crosspoint contains an internal queue (XQ), which can store one or more packets to be routed. Traffic rates to be realized between all Input/Output (IO) pairs of the switch are specified in an N×M traffic rate matrix, where each element equals a number of requested cell transmission opportunities between each IO pair within a scheduling frame of F time-slots. An efficient algorithm for scheduling N traffic flows with traffic rates based upon a recursive and fair decomposition of a traffic rate vector with N elements, is proposed. To reduce memory requirements a shared row queue (SRQ) may be embedded in each row of the switching matrix, allowing the size of all the XQs to be reduced. To further reduce memory requirements, a shared column queue may be used in place of the XQs.
