  • Patent number: 10284682
    Abstract: Disclosed herein is a system comprising a plurality of agents that desire access to a resource; a finite amount of an internal state; a processor that is configured to enforce an arbitration mechanism to translate a quota specification for the plurality of agents according to a set of rules comprising i) all classes of service that are serviceable are served according to the quota specification; ii) if an underserviced class is not serviceable, a serviceable class continues to be granted access to the one or more resources even if the granted access leads to an increase in the underservice of a non-serviceable class; iii) as soon as the underserviced class becomes serviceable, it will in priority recuperate its accumulated disadvantage until its quota specification is reached; and iv) the internal state is updated upon reaching boundary conditions.

  • Patent number: 10182016
    Abstract: Congestion management for data traffic in a virtual domain identifies a congestion source and sends a message to the source to adjust data traffic rates. The source may be a virtual machine hosted by a physical server with one or more virtual servers incorporated. A congestion manager may identify the source and send the message to the source without affecting other data sources hosted by the physical server or the virtual servers. In some embodiments, information about the congestion source may be encapsulated in a packet payload readable only by the congestion source so only the congestion source receives the instruction to adjust the transmission rate.

  • Patent number: 10042683
    Abstract: A method for all-to-all message exchange between program tasks including N>1 hierarchy levels ln, n=1 to N, in which a first level l1 includes a plurality of group tasks and each higher level l(n>1) includes at least one group of level l(n?1) groups to which that task belongs in respective hierarchy levels of the network topology; sending a message via the interconnection network to a respective destination task whose hierarchical identifier is determined; and using the hierarchical identifier to send the program task and the network topology, such that the resulting exchange pattern for the all-to-all message exchange exploits a hierarchical distance in the network topology in a desired manner.

  • Patent number: 9998377
    Abstract: Embodiments relate to controlling workload flow on converged Ethernet links. An aspect includes coupling, by a processing device, a first control loop to a second control loop. The second control loop monitors the operation of the first control loop. An equilibrium set point is initialized for the second control loop prior to commencing operation of the first control loop. Accordingly, the equilibrium set point value is adjusted in the second control loop continuously based on a rate of operation of the first control loop.

  • Publication number: 20180145926
    Abstract: IEEE 802.1Q and Enhanced Transmission Selection provide only eight different traffic classes that may be used to control bandwidth in a particular physical connection (or link). Instead of relying only on these eight traffic classes to manage bandwidth, the embodiments discussed herein disclose using an Enhanced Transmission Selection scheduler that permits a network device to set the bandwidth for an individual virtual LAN. Allocating bandwidth in a port based on a virtual LAN ID permits a network device to allocate bandwidth to, e.g., millions of unique virtual LANs. Thus, this technique may increase the granular control of the network fabric and its performance.

  • Patent number: 9973420
    Abstract: In one embodiment, a method includes receiving first overlay network traffic via a first input overlay tunnel at a multi-protocol virtual tunnel end point (VTEP) implemented in an accelerated network interface card (NIC) of a server. The method also includes routing the first overlay network traffic to a second overlay network tunnel which adheres to a second overlay network protocol in response to a determination that a destination of the first overlay network traffic is specified as the second overlay network tunnel. Moreover, the method includes receiving second overlay network traffic via the first input overlay tunnel at the multi-protocol VTEP. The method also includes bridging the second overlay network traffic to a first destination overlay network tunnel terminated at the multi-protocol VTEP in response to a determination that a destination of the second overlay network traffic is specified as the first destination overlay network tunnel.

  • Publication number: 20180069802
    Abstract: In one embodiment, a method includes receiving a plurality of flows, each flow comprising packets of data and assigning a service credit to each of the plurality of flows. In addition, the method includes assigning a weight parameter to each of the plurality of flows, and selecting a flow from a head of a first control queue unless the first control queue is empty or there is indication that the first control queue should be avoided. A flow is selected from a head of a second control queue in response to a determination that the first control queue is empty or there is indication that the first control queue should be avoided. Additionally, the method includes providing a number of units of service to the selected flow. Moreover, the method includes decreasing the selected flow's service credit by an amount corresponding to the number of units of service provided thereto.

  • Patent number: 9832030
    Abstract: An approach is described for routing data to a plurality of output terminals via a integrated switch router including a crossbar switch having both a crossbar and a plurality of crossbar bypass lines. Whereas the crossbar may connect each input of the crossbar switch to each output of the crossbar switch, each of the plurality of crossbar bypass lines may connect a single input of the crossbar switch to a corresponding single output of the crossbar switch. According to such approach, a replicated copy of a multicast packet may be forwarded to an output terminal via a crossbar bypass line in parallel with other data forwarded via the crossbar, thus increasing integrated switch router bandwidth.

  • Patent number: 9712451
    Abstract: A virtual network is implemented on a physical network. A virtual network data packet is tunneled through the physical network via encapsulation within a physical network data packet and via transmission of the physical network data packet through the physical network. A network congestion notification capability of the virtual network is preserved and modified during transmission of virtual network data through the physical network and vice-versa. Congestion notification metadata can be copied from a header of a virtual network data packet to a header of a physical network data packet when the virtual network data packet is encapsulated into the physical network data packet. Congestion notification metadata can be copied from a header of a physical network data packet to a header of a virtual network data packet when the virtual network data packet is decapsulated from the physical network data packet.

  • Patent number: 9686203
    Abstract: In one embodiment, a system includes a hardware processor and logic integrated with and/or executable by the processor. The logic is configured to classify a traffic flow into a traffic class based on at least one criteria related to the traffic flow and request that a credit manager remap flow credits corresponding to a first traffic class to flow credits corresponding to a second traffic class. In another embodiment, a method for providing credit-based flow control includes classifying a traffic flow into a traffic class based on at least one criteria related to the traffic flow, the traffic class being selected from a plurality of traffic classes. The method also includes storing an identifier indicating the traffic class of packets of the traffic flow according to a virtual local area network (VLAN) identifier in a three bit VLAN tag portion of a header of one or more of the packets.
