Method and apparatus for transmitting data packets and method and apparatus for receiving data packets

A data packet comprises a header and a payload. At least one digital signal processor is used to configure the payload to transport at least one full service data unit, one or two service data unit fragments, or at least one full service data unit and at least one service data unit fragment. A service data unit fragment is only located (i) at the beginning of the payload or at the end of the payload or (ii) at the beginning of the payload and at the end of the payload. At least one digital signal processor is used to configure a single field in the header consisting of a first bit and a second bit, even when a number of full service data units and service data unit fragments in the payload is more than two, the single field indicating whether (i) the payload begins with a fragment of a service data unit and (ii) the payload ends with a service data unit fragment. At least one digital signal processor is used to form the data packet including the configured header and the configured payload. A transmitter transmits the data packet.

The method includes: driving a host vehicle and a target vehicle at a same speed on a road segment; the host vehicle being located behind the target vehicle; a constant distance is maintained between the host vehicle and the target vehicle; the host vehicle is equipped with a host vehicular communication unit, the target vehicle is equipped with a target vehicular communication unit communicating with the host vehicular communication unit; calculating a throughput and a round trip time RTT from the target vehicular communication unit to the host vehicular communication unit; repeating driving the host vehicle and target vehicle N times, and calculating an average throughput and an average round trip time (RTT) of the N times; and calculating a network performance parameter according to the average throughput and the RTT.

Reducing latency in rendering of content

Content rendering techniques are disclosed that reduce latency in rendering of content by extracting resource intensive content from the content. An example method may include identifying items of resource intensive content included in an item of original content, and extracting the items of resource intensive content from the item of original content. The extracted items of resource intensive content are replaced with corresponding extraction markers in the item of original content to create an item of modified content. At the time of rendering the item of modified content, the extracted items of resource intensive content may be retrieved and appropriately inserted into the item of modified content to recreate the item of original content.

APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING BROADCAST SIGNAL

A method for delivering data in a transmitter includes generating service layer signaling (SLS) information comprising information for discovery and acquisition of at least one content component, wherein the SLS information and the at least one content component are carried based on a Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol or an MPEG Media Transport (MMT) protocol; generating service list table (SLT) information comprising bootstrap information for acquiring the SLS information; encapsulating the at least one content component, the SLS information and the SLT information; and transmitting a broadcast signal comprising the at least one content component, the SLS information and the SLT information

Hardware based packet replication at tail end node

Aspects of the disclosed technology address limitations relating to packet replication for multi-destination traffic, by providing methods for performing hardware-based replication in network infrastructure devices, such as switches. In some aspects, application specific integrated circuits (ASICs) resident in physical devices can be used to perform packet replication. Depending on implementation, a hardware-based replication process can include steps for receiving a first packet that includes a first outer header containing first address information, receiving a second packet including a second outer header containing a hardware replication flag, forwarding the first packet to all virtual tunnel endpoints (VTEPs) connected with the TOR switch, and performing hardware replication for the second packet based on the hardware replication flag to generate one or more unicast packets. Systems and machine readable media are also provided.

MAINTAINING CLIENT VERSION AFFINITY DURING A SERVER CLUSTER UPGRADE
20200073650 · 2020-03-05 · ·

Maintaining client version affinity during a rolling server cluster upgrade includes a server in the server cluster receiving a request from a client and checking the request for a version cookie indicating a software version that the client is running. Responsive to a determination that the server is running the same software version as the client, the server serves the request. Responsive to a determination that the client is running a software version matching a previous software version of the server, the server initiates a software upgrade on the client instead of servicing the request. Responsive to a determination that the server is not running the same software version as the client, the server forwards the request to one of the other servers in the server cluster that is running the same software version as the client.
