The invention relates to a cross-data-center RDMA flow control method and device, equipment, a storage medium and a program product. Comprising the following steps: in an initialization process, receiving a resource reservation protocol message of next-hop transmission equipment, and determining a cache space value reserved by the next-hop transmission equipment; in the transmission process of the RDMA data packet, receiving the current credit value transmitted by the next hop transmission equipment, and updating the maintained cache space value; determining whether to continue to execute the transmission task according to the updated cache space value; if yes, the corresponding data block is sent to the next-hop transmission device, the updated cache space value is updated again according to the size of the data block, and the maintained cache space value is obtained. By adopting the method, flow control based on credit is realized, data overflow and loss caused by insufficient cache space of next-hop transmission equipment can be avoided, and transmission guarantee of high throughput and zero packet loss is provided for RDMA flow.

U-Turn detour paths, though the head-end router of a primary label switched path (LSP), are configured and used to enable fast failover to a secondary LSP, while avoiding reserving bandwidth (e.g., on links unused by primary and secondary paths) unnecessarily.

A method of operating a network device is provided that includes receiving a message, determining whether the message is associated with a known label-switched path (LSP), enqueuing the message in a first queue on the network device in response to determining that the message is associated with a known label-switched path, and enqueuing the message in a second queue, different than the first queue, on the network device subsequent to determining that the message is associated with an unknown label-switched path. The method can further include determining whether there are any messages associated with a known label-switched path enqueued in the first queue and continuously processing messages associated with the known label-switched path before either a message is dequeued from the second queue or the program yields to allow other pending workloads or processes to run.
