  • Publication number: 20180300165
    Abstract: A computing system can include a server computer and a configurable hardware platform. The server computer can include instances or domains such as a management partition and a user partition. The management partition can be used to perform management services for the user partitions and the configurable hardware platform. The configurable hardware platform is coupled to the server computer, and can include a host logic and a configurable application logic. In an embodiment, the computing system is configured to provide the user partition with physical or virtual access to a first part of the configurable hardware platform through the host logic in the configurable hardware platform. The computing system is also configured to provide the user partition with virtual access to certain portions/resources associated with the configurable hardware platform.

  • Publication number: 20180302281
    Abstract: The following description is directed to a logic repository service supporting adaptable host logic. In one example, a method of a logic repository service can include receiving a first request to generate configuration data for configurable hardware using a specification for application logic. The method can include selecting a particular host logic shell from a group of host logic shells. The particular host logic shell can be used to encapsulate the application logic when the configurable hardware is configured. Configuration data for the configurable hardware can be generated. The configuration data can include data for implementing the application logic and at least a portion of the particular host logic shell. The method can include receiving a second request to download the configuration data to a host server computer comprising the configurable hardware. The configuration data can be transmitted to the host server computer in response to the second request.

  • Patent number: 10044603
    Abstract: A fast reroute (FRR) implementation utilizes an optimized FRR table to implement a fast switchover to a backup link upon detecting a primary link failure on a label switched path (LSP). The switchover can be performed in a negligible amount of time (close to zero milliseconds) based on a backup indicator flag which can be dynamically updated. The FRR table stores pre-determined backup egress interfaces and FRR labels corresponding to primary egress interfaces to minimize the switchover time.

  • Patent number: 10038572
    Abstract: A packet processor may implement programmable tunnel creation. A network packet may be received at a packet processor. A tunneling protocol may be identified for the network packet. The packet processor may access one or more memories to obtain tunnel header data that includes a tunnel header and field identifiers which indicate respective fields in the tunnel header that are determined based on data in the network packet. The tunnel header data may have been stored in the one or more memories prior to receiving the network packet. The network packet may be modified to insert the tunnel header into the network packet including the respective fields indicated by the field identifiers. The modified packet may then be transmitted.

  • Patent number: 10027594
    Abstract: One pre-configured code point from of a plurality of code points for a multiprotocol label switching (MPLS) traffic class represents a congestion marked code point associated with traffic congestion and the remaining code points represent not-congestion marked. Congestion associated with a label switching path can be determined based on a congestion notification from a router queue and on a pre-determined congestion indicator from a packet header.

  • Patent number: 9948756
    Abstract: Provided are methods, computer devices, and computer-readable medium for automatic generation of a pipeline. In various implementations, a computing device may determine modifications to be made to packets conforming to each of a plurality of packet types, and identify a first modification that is dependent on a second modification. The computing device may further determine a number of pipeline stages for a pipeline circuit such that the second modification is performed in a pipeline stage prior to a pipeline stage in which the first modification is performed. The computing device may further generate a description of a pipeline stage for each of the number of pipeline stages, where each pipeline stage can perform at least one of extracting a first value, calculating a second value, or inserting a third value, where the extracting, calculating, and inserting uses values provided to each pipeline stage by an immediately preceding pipeline stage.

  • Patent number: 9860168
    Abstract: A packet processor may implement network packet modification. A network packet may be received at a packet processor. A packet header modification may be identified for the network packet. The packet processor may access a memory to traverse a dependency graph for the packet header modification to obtain an operation to apply the packet header modification and dependent operations to update fields in the packet header to be changed as a result of the packet header modification. The dependency graph may have been stored in the memory prior to receiving the network packet. The obtained operations may be performed according to the traversal of the dependency graph. The modified packet may then be transmitted.
