Technologies for protocol-agnostic network packet segmentation includes determining whether a size of a payload of a network packet to be transmitted by the compute device exceeds a maximum size threshold and segmenting the payload into a plurality of segmented payloads if the size of the payload exceeds the maximum size of threshold. The payload may be segmented based on segmentation metadata associated with the network packet.

Techniques for improved storage in a multi-cloud computing environment are provided. For example, a system manager for a storage system comprises a client interface layer configured to provide one or more application programing interfaces for one or more clients accessing the storage system, and a client interface layer handler configured to manage the one or more application programing interfaces of the client interface layer. Further, the system manager comprises a unified storage resource interface layer configured to provide a set of application programming interfaces to enable access for the one or more clients to a storage resource layer operatively coupled to the unified storage resource interface layer. The storage resource layer comprising one or more public cloud platform-based storage resources and a blockchain manager that coordinates access to one or more enterprise-level storage resources and one or more individually-owned storage resources.

An apparatus for communication between a sending application and a receiving application of a receiving apparatus includes a processor that is configured to establish a stream for transmitting data between the sending application and the receiving application; receive a first request from the sending application to transmit metadata to the receiving application; receive a second request from the sending application to transmit application data to the receiving application; responsive to a determination that a frame that includes the application data and the metadata has a size that is smaller than or equal to a maximum frame size, construct the frame to include the application data and the metadata; and transmit the frame in a packet to the receiving apparatus.

Technologies for dynamic accelerator selection include a compute sled. The compute sled includes a network interface controller to communicate with a remote accelerator of an accelerator sled over a network, where the network interface controller includes a local accelerator and a compute engine. The compute engine is to obtain network telemetry data indicative of a level of bandwidth saturation of the network. The compute engine is also to determine whether to accelerate a function managed by the compute sled. The compute engine is further to determine, in response to a determination to accelerate the function, whether to offload the function to the remote accelerator of the accelerator sled based on the telemetry data. Also the compute engine is to assign, in response a determination not to offload the function to the remote accelerator, the function to the local accelerator of the network interface controller.

A method for Xx/Xn interface communication is disclosed, comprising: at an Xx/Xn gateway for communicating with, and coupled to, a first and a second radio access network (RAN), receiving messages from the first RAN according to a first Xx/Xn protocol and mapping the received messages to a second Xx/Xn protocol for transmission to the second RAN; maintaining state of one of the first RAN or the second RAN at the Xx/Xn gateway; executing executable code received at an interpreter at the Xx/Xn gateway as part of the received messages; altering the maintained state based on the executed executable code; and receiving and decoding an initial Xx/Xn message from the first RAN; identifying specific strings in the initial Xx/Xn message; matching the identified specific strings in a database of stored scripts; and performing a transformation on the initial Xx/Xn message, the transformation being retrieved from the database for stored scripts, the stored scripts being transformations.
