A computer-implemented method comprising: (i) defining a new ethertype to be used in communicating PIDs (process identification codes), with the new ethertype being assigned a new ethertype code; (ii) determining a selected abstraction layer from a plurality of abstraction layers to be used in communicating PIDs; and (iii) making a plurality of network communications among and between computers of a networked computers system, with each communication, with the making of each given communication including: (a) inserting the new ethertype code and a PID of a process causing the given communication to occur into a data structure, and (b) communicating the data structure between computers of the networked computers system at the selected abstraction layer.

A port number extension method and a switch are provided. A first switch determines bits for identifying the first switch in a Media Access Control (MAC) address in an identifier (ID) of a specified bridge; calculates a bit for port number extension according to the bits for identifying the first switch; and combines the bit for port number extension and original bits for specifying a port, to obtain new bits for specifying a port. In this way, a problem that Spanning Tree Protocol (STP) port numbers are insufficient in a super virtual fabric with a massive quantity of ports is resolved.

The present disclosure provides a data processing method adapted to access network architecture, and the access network architecture. The data processing method includes: providing a data distribution and reordering module; acquiring, by the data distribution and reordering module, control information, the control information including information about a byte length of the data distributed over an air-interface channel and information about an air-interface link during air-interface cell switch; and distributing, by the data distribution and reordering module, data received from a PDCP layer toward a central RLC layer/a remote RLC layer in accordance with the control information, reordering data from the central RLC layer/remote RLC layer, and transmitting the reordered data to the PDCP layer.

A communication device communicates a radio frame including a preamble and a data field of a physical layer (PHY). The preamble includes an L-STF (Legacy Short Training Field), an L-LTF (Legacy Long Training Field), an L-SIG (Legacy Signal Field), an EHT-SIG-A (Extremely High Throughput Signal A Field), an EHT-STF, and an EHT-LTF, and the EHT-SIG-A includes a field indicating a standard that the radio frame complies with.

A method of utilizing the same hardware network interface card (NIC) in a gateway of a datacenter to communicate datacenter tenant packet traffic and packet traffic for a set of applications that execute in the user space of the gateway and utilize a network stack in the kernel space of the gateway. The method sends and receives packets for the datacenter tenant packet traffic through a packet datapath in the user space. The method sends incoming packets from the NIC to the set of applications through the datapath in the user space, a user-kernel transport driver connecting the kernel network stack to the datapath in the user space, and the kernel network stack. The method receives outgoing packets at the NIC from the set of applications through the kernel network stack, the user-kernel transport driver, and the data path in the user space.

The present disclosure relates receiving a plurality of Protocol Data Units (PDU) of a PDU sequence over a radio interface; detecting that a PDU of the sequence of the received PDUs is missing, wherein for each of the received PDUs, identifying which Service Data Unit(s) (SDU) it relates to; based on said identifying, determining that a complete SDU is obtainable from one or several PDUs of the received PDUs, which one or several PDUs are later in the sequence of the received PDUs than the missing PDU; obtaining the complete SDU from said one or several PDUs; performing a packet inspection of the obtained complete SDU to determine the type of data it carries; and based on the performed packet inspection, determining that the complete SDU fulfils a predetermined criterion; and delivering the complete SDU before receiving a retransmission of the PDU which is missing.

Methods, apparatus and systems for indicating transmission failures in a wireless communication are disclosed. In one embodiment, a method performed by a wireless communication device is disclosed. The method comprises: obtaining, by a first layer module of the wireless communication device, an indication from a second layer module of the wireless communication device. The first layer module is configured for performing a process at a first layer. The second layer module is configured for performing a process at a second layer that is different from the first layer. The indication indicates whether there is a transmission failure of the wireless communication device at the second layer.

A network slice controller obtains health information of an active network slice provided by a first vendor and health information of a set of backup network slices provided by a second vendor. The network slice controller evaluates, using a set of policies corresponding to management of the active network slice, the health information of the active network slice to determine whether the active network slice has failed. As a result of the failure of the active network slice, the network slice controller identifies one or more backup network slices of the set of backup network slices to serve as new active network slices. The network slice controller activates these one or more backup network slices to serve as the new active network slices for the network.

The present invention is a method, system and apparatus for configuring a client-side communications protocol stack. In a method of the invention, a mapping can be consulted to determine a set of client-side protocol stack components which correspond to a set of protocol stack components in a server side protocol stack instance. Subsequently, a listing can be created of the determined set of client-side protocol stack components. Finally, the listing can be published for access by externally disposed client computing processes. Preferably, the listing can be reversed. Also, the consulting step further can include determining at least one attribute to be applied to at least one of the client-side protocol stack components when enabling a client-side protocol stack to interoperate with the server-side protocol stack instance.
