摘要： A network traffic management apparatus includes a first memory including a flow cache table including a plurality of entries. The network traffic management apparatus further includes configurable hardware logic coupled to the first memory and a processor, the configurable hardware logic including a valid split table including a plurality of entries, wherein each of the plurality of entries includes a validity bit. The configurable hardware logic is configured to implement periodically determining whether the validity bit of each of the valid split table entries is set. Additionally, the configurable hardware logic is further configured to implement retrieving one of the plurality of flow cache table entries corresponding to an index value associated with one of the valid split table entries, when it is determined that the validity bit of the one of the valid split table entries is set.

摘要： Technology related to application deployment across network devices including smart network interface cards. In one example, a method includes distributing an application across a plurality of locally connected computing subdomains. The subdomains can include a mixture of general and special purpose computing subdomains, such as for example, a main computer and an associated smart network interface devices or systems, such as for example a smart network interface card (NIC). The subdomains can each run hypervisors that are bridged to allow a single virtual machine to operate across the subdomains. The application can include multiple portions. For example, an application can be split by different functionalities. The application portions can be tagged to indicate which subdomain they are to be executed within. If the chosen subdomain has available the requisite resources, the application can be detached and distributed to the chosen subdomain.

摘要： Technology related to managing network traffic flows is disclosed. In one example, a method can include searching a first data structure to determine whether a first entry associated with a network flow is present in the first data structure. In response to determining the first entry is present in the first data structure, at least a portion of the first entry can be used to generate an index for a flow cache. An action can be performed on the network packet as indicated by a flow cache entry, where the flow cache entry is located in the flow cache at the generated index.

摘要： Technology related to scheduling services on a platform including configurable computing resources is disclosed. In one example, a method includes scheduling a service to execute on a first computing node based on an availability of general-purpose computing resources at the first computing node. The first computing node can be selected from a plurality of computing nodes. Network traffic transiting the first computing node can be analyzed during the execution of the service to determine a hardware accelerator of a second computing node is capable of assisting the execution of the service. The service can be scheduled to execute on the second computing node and the hardware accelerator of the second computing node can be used to assist with the execution of the service.

摘要： Technology related to orchestrating a configuration of a programmable accelerator is disclosed. In one example, a method includes executing a service within a container runtime. The service can include a software application and an orchestrator application, where the orchestrator application is adapted to configure a programmable hardware accelerator and the software application adapted to interoperate with the programmable hardware accelerator. The orchestrator application, executing within the container runtime, can be used to retrieve a system image from a file repository. The system image can include configuration data for the programmable hardware accelerator. The orchestrator application, executing within the container runtime, can be used to configure the programmable hardware accelerator.
