摘要： In one embodiment, layer-2 (L2) ports of a network device may each be assigned to a particular virtual service domain (VSD). One or more virtual service engines (VSEs) may also be assigned in a particular order to each VSD, where each VSE is configured to apply a particular service to traffic traversing the VSE between ingress and egress service ports. Interconnecting the L2 ports and the ingress and egress service ports is an illustrative virtual Ethernet module (VEM), which directs traffic it receives according to rules as follows: a) into a destination VSD via the one or more correspondingly assigned VSEs in the particular order; b) out of a current VSD via the one or more correspondingly assigned VSEs in a reverse order from the particular order; or c) within a current VSD without redirection through a VSE.

摘要： Flows of packets are dynamically mapped to resource queues. Flows of packets are received at a network device to be routed from the network device in a network. Each flow comprises packets to be sent from a source to a connection. Data is stored for a queue allocation table that maintains a plurality of buckets to which received packets for a flow are assigned and indicating which of a plurality of resource queues are allocated for respective buckets. For each packet in a flow, a hash function is computed from values in a header of the packet and the packet is assigned to one of the plurality of buckets based on the computed hash function. One of a plurality of resource queues is allocated for each bucket to which packets are assigned based on the computed hash function.

摘要： Techniques are provided for improve quality of service on uplinks in a virtualized environment. At a server apparatus having a plurality of physical links configured to communicate traffic over a network to or from the server apparatus, forming an uplink group comprising a plurality of physical links. A first class of service is defined that allocates a first share of available bandwidth on the uplink group, and a second class of service is defined that allocates a second share of available bandwidth on the uplink group. The bandwidth for the first class of service is allocated across the plurality of physical links of the uplink group, and the bandwidth for the second class of service is allocated across the plurality of physical links of the uplink group. Traffic rates are monitored on each of the plurality of physical links to determine if a physical link is congested indicating that a bandwidth deficit exists for a class of service. In response to determining that one of the plurality of physical links is congested, bandwidth is reallocated for a class of service to reduce the bandwidth deficit for a corresponding class of service.

摘要： Methods, systems and apparatus for suppressing redundancy in data transmission over networks are provided. Data segments are transmitted from a transmitting DPU to a receiving DPU. Initially, only signatures of the transmitted data segments are stored in a cache at the transmitting DPU. A data segment is stored in the cache only if it satisfies a redundancy-suppressing admission policy. Such a data segment is referred to as a redundant data segment. The redundant data segment is also stored in a cache at the receiving DPU. The transmitting DPU transmits the signatures of the redundant data segments to the receiving DPU, which then extracts the redundant data segments from its cache. Therefore, transmission of the redundant data segments is suppressed.
