摘要： A network interface controller (NIC) capable of efficient load balancing among the hardware engines is provided. The NIC can be equipped with a plurality of ordering control units (OCUs), a queue, a selection logic block, and an allocation logic block. The selection logic block can determine, from the plurality of OCUs, an OCU for a command from the queue, which can store one or more commands. The allocation logic block can then determine a selection setting for the OCU, select an egress queue for the command based on the selection setting, and send the command to the egress queue.

摘要： A data-driven intelligent networking system that can facilitate tracing of data flow packets is provided. The system add tracer packets to data flow packets arriving at an ingress point of the network. As the tracer packets progress through network in-band with the data flow packets, the system can copy, at each switch, trace data into pre-defined fields in the tracer packets. When the data flow packets arrive at an egress point of the network the system can separate the trace data from the data flow packet for analysis. Based on the analysis of the trace data, the system can adopt one or more policies to mitigate the impact of congestion on time-sensitive applications.

摘要： Systems and methods are provided for managing a data communication within a multi-level network having a plurality of switches organized as groups, with each group coupled to all other groups via global links, including: at each switch within the network, maintaining a global fault table identifying the links which lead only to faulty global paths, and when the data communication is received at a port of a switch, determine a destination for the data communication and, route the communication across the network using the global fault table to avoid selecting a port within the switch that would result in the communication arriving at a point in the network where its only path forward is across a global link that is faulty; wherein the global fault table is used for both a global minimal routing methodology and a global non-minimal routing methodology.

摘要： A traffic controller device for distributing or otherwise controlling the distribution of routing information may be included in a telecommunications network. The traffic controller may receive routing tables from a plurality of network devices, such as one or more provider edge devices of the network. The traffic controller, upon receiving the routing information from the provider edge devices, may generate a routing table associated with each device providing the routing information. The traffic controller may also provide updates to one or more of the networking devices associated with the controller. The traffic controller may alter or update, at the traffic controller, the routing table associated with the target provider edge device based on the network policy. The routing information in the routing table for that device and maintained by the traffic controller may be updated with a new route or new local preferred parameter value.

摘要： Embodiments provide techniques for providing return-link routing in a hybrid communications network that includes a number of different networks having different characteristics. User terminal routing systems (UTRSs) provide interfaces between local user networks and the multiple communications networks of the hybrid network. Each UTRS can include a routing table having stored mappings that are populated according to forward-link communications (implicitly or explicitly), each associating a respective one of a plurality of routing table entries with one of the communications networks. When a UTRS receives return-link data from its respective local user network, the received data indicates a destination node. The UTRS can determine which of the stored mappings corresponds to the destination node and can route the received return-link data over a selected one of the communications networks in accordance with the identified one of the mappings.

摘要： Methods and systems are provided for performing lossy dropping and ECN marking in a flow-based network. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow are acknowledged after reaching the egress point of the network, and the acknowledgement packets are sent back to the ingress point of the flow along the same data path. As a result, each switch can obtain state information of each flow and perform per-flow packet dropping and ECN marking.

摘要： A network interface controller (NIC) capable of facilitating efficient memory address translation is provided. The NIC can be equipped with a host interface, a cache, and an address translation unit (ATU). During operation, the ATU can determine an operating mode. The operating mode can indicate whether the ATU is to perform a memory address translation at the NIC. The ATU can then determine whether a memory address indicated in the memory access request is available in the cache. If the memory address is not available in the cache, the ATU can perform an operation on the memory address based on the operating mode.

摘要： A network interface controller (NIC) capable of facilitating fine-grain flow control (FGFC) is provided. The NIC can be equipped with a network interface, an FGFC logic block, and a traffic management logic block. During operation, the network interface can determine that a control frame from a switch is associated with FGFC. The network interface can then identify a data flow indicated in the control frame for applying the FGFC. The FGFC logic block can insert information from the control frame into an entry of a data structure stored in the NIC. The traffic management logic block can identify the entry in the data structure based on one or more fields of a packet belonging to the flow. Subsequently, the traffic management logic block can determine whether the packet is allowed to be forwarded based on the information in the entry.

摘要： A method for execution by a processor of a host having an external interface for connection to at least one other network element of a packet-based data network, the host storing a routing table and implementing a container connected to a bridge, the container being addressable by an internal address on a bridge network associated with the bridge. The method includes obtaining an indication of a request for the container to join a multicast group. In response to the obtaining, a request is sent via the external interface for the host to join the multicast group. The routing table may be modified so as to make the bridge a next hop for future packets obtained from the external interface and destined for the multicast group. The routing table may also be modified so as to make the external interface a next hop for future packets that are obtained from the bridge, whose source address is the internal address of the container and that are destined for the multicast group. The method also includes setting up an expiry parameter increase for such future packets.

摘要： A switch equipped with a self-managing reduction engine is provided. During operation, the reduction engine can use a timeout mechanism to manage itself in different latency-induced or error scenarios. As a result, the network can facilitate an efficient and scalable environment for high performance computing.
