摘要： A system that includes a routing device and a proxy server in a private network. The routing device is configures itself to route data traffic for a network device within a private network using private links. The routing device forwards an access request requesting access to a destination address in a public network from the network device to the proxy server. The proxy server determines whether the access request satisfies a set of access rules and generates an access request response. The routing device forwards the access request response from the proxy server to the network device. The routing device configures itself to route data traffic between the network device and the destination address using public links in response to receiving an access approval message. The routing device communicates data traffic between the network device and the destination address using public links.

摘要： A mechanism is provided in a data processing system comprising at least one processor and at least one memory, the at least one memory comprising instructions that are executed by the at least one processor and configure the at least one processor to implement a path query cache. Responsive to receiving a path query from a process executing in the data processing system, the path query cache performs a lookup of the path query in the path query cache. The path query identifies a source port, a source address and a destination address. The path query cache stores a plurality of entries, each entry comprising a source port, a source address, a destination address, the source and destination global identifiers, and good/bad flag indicating whether a path associated with the entry is available or not. Responsive to the path query cache determining the path query matches a valid entry in the plurality of entries, the path query cache returns a result to the process. The result comprises the source and destination global identifiers and the good/bad flag from the valid entry.

摘要： A novel design of a gateway that handles traffic in and out of a network by using a datapath pipeline is provided. The datapath pipeline includes multiple stages for performing various data-plane packet-processing operations at the edge of the network. The processing stages include centralized routing stages and distributed routing stages. The processing stages can include service-providing stages such as NAT and firewall. The gateway caches the result previous packet operations and reapplies the result to subsequent packets that meet certain criteria. For packets that do not have applicable or valid result from previous packet processing operations, the gateway datapath daemon executes the pipelined packet processing stages and records a set of data from each stage of the pipeline and synthesizes those data into a cache entry for subsequent packets.

摘要： A routing device capable of performing application layer data caching is described. Application data caching at a routing device can alleviate the bottleneck that an application data host may experience during high demands for application data. Requests for the application data can also be fulfilled faster by eliminating the network delays for communicating with the application data host. The techniques described can also be used to perform analysis of the underlying application data in the network traffic transiting though a routing device.

摘要： One embodiment provides a system that facilitates optimal forwarding decisions based on device-specific routing parameters. During operation, the system receives, from a transmitting device, an advertisement for a name prefix, wherein the advertisement includes route parameters specific to the transmitting device. The system stores the route parameters based on the name prefix and a first interface associated with the transmitting device. In response to receiving an interest with a name that includes the name prefix, the system obtains a matching entry in a forwarding information base based on the name prefix, wherein the matching entry indicates one or more outgoing interfaces and corresponding route parameters, which include the first interface and the corresponding stored route parameters. The system selects a second interface from the outgoing interfaces based on the route parameters for the outgoing interfaces, and forwards the interest via the selected second interface.

摘要： A novel design of a gateway that handles traffic in and out of a network by using a datapath daemon is provided. The datapath daemon is a run-to-completion process that performs various data-plane packet-processing operations at the edge of the network. The datapath daemon dispatches packets to other processes or processing threads outside of the daemon. Datapath operations at lower layers of the network protocol model are processed by the datapath daemon within its run-to-completion thread, while datapath operations at higher layers of the network protocol model are processed by data plane processes external to the datapath daemon.
