The platform is directed to various aspects of content transmission. The platform causes a viewing device to receive fragment-level metadata associated with a first fragment of content. The platform receives a request for a second fragment of the content, immediately subsequent to the first fragment of the content. The platform determines that the second fragment of the content is not stored at a content storage device at a time of receiving the request, and that the second fragment of the content is expected to be stored at the content storage device within a defined time period. Responsive to these determinations, the platform holds the received request for the defined time period. The platform determines, prior to expiration of the defined time period, that the second fragment of the content is stored at the content storage device, and transmits the second fragment of the content to the viewing device.

Content delivery platform

A system, comprising a compute node and coupled network adapter (NA), that supports improved data transfer request buffering and a more efficient method of determining the completion status of data transfer requests. Transfer requests received by the NA are stored in a first buffer then transmitted on a network interface. When significant network delays are detected and the first buffer is full, the NA sets a flag to stop software issuing transfer requests. Compliant software checks this flag before sending requests and does not issue further requests. A second NA buffer stores additional received transfer requests that were perhaps in-transit. When conditions improve the flag is cleared and the first buffer used again. Completion status is efficiently determined by grouping network transfer requests. The NA counts received requests and completed network requests for each group. Software determines if a group of requests is complete by reading a count value.

Software aware throttle based flow control

A system comprising a compute node and coupled network adapter (NA) that allows the NA to directly use CPU virtual addresses without pinning pages in system memory. The NA performs memory accesses in response to requests from various sources. Each request source is assigned to context. Each context has a descriptor that controls the address translation performed by the NA. When the CPU wants to update translation information it sends a synchronization request to the NA that causes the NA to stop fetching a category of requests associated with the information update. The category may be requests associated with a context or a page address. Once the NA determines that all the fetched requests in the category have completed it notifies the CPU and the CPU performs the information update. Once the update is complete, the CPU clears the synchronization request and the NA starts fetching requests in the category.
