A server processers received real-time transport protocol packets from a first device to obtain sequentially ordered packets at a first buffer. The server decodes the sequentially ordered packets to obtain decoded packets at a decoder. The server encodes the decoded packets to obtain encoded packets at an encoder. The server transmits the encoded packets from the encoder to a storage unit. The server fetches the encoded packets from the storage unit at a first interval using a second buffer. The server transmits the encoded packets from the second buffer to a second device at a second interval.

Methods and systems for determining traffic information for devices along one or more routes are described. A content server may send a message to a plurality of devices along a route. The message may comprise an indication requesting each of the devices to send, to the content server, status information regarding the respective device. Intermediary devices may receive the message, respond with the requested information, and forward the message through the route. The message may comprise a stateless messaging protocol message such as an ICMP or UDP packet.

A method is provided for performing zero-copy distribution of data samples between applications running on the same node in a system using an Object Management Group (OMG) Data Distribution Service (DDS) and/or a Real-Time Publish Subscribe (RTPS) protocol. Further provided is a method for selecting the network representation to communicate with a DataReader in a system using an Object Management Group (OMG) Real-Time Publish Subscribe (RTPS) protocol. Still further provided is the combination of these two methods to communicate transparently using zero-copy within the same node and not using zero-copy for different nodes. Embodiments of this invention lead to a relatively small communication latency that is constant and independent of the data size for applications running within a single node.

Methods and systems are provided for latency-oriented router. An incoming packet is received on a first interface. The type of the incoming packet is determined. Upon the detection that the incoming packet belongs to latency-critical traffic, the incoming packet is duplicated into one or more copies. Subsequently, the duplicated copies are sent to a second interface in a delayed fashion where the duplicated copies are spread over a time period. The duplicated copies are received and processed at the second interface.

A technique of transporting a time protocol message for time-sensitive networking, TSN, from a first station (910) to a second station (920) through a wireless network (900) including at least one radio device wirelessly connected to at least one base station (400) of the wireless network (900) is provided. As to a method aspect, a method performed by at least one or each of the at least one radio device comprises a step of transmitting to the wireless network (900) a radio device request message requesting establishment of a packet data unit, PDU, session between the radio device and the wireless network (900), the radio device request message being indicative of a time protocol of the time protocol message. The method further comprises at least one of the steps of receiving from and transmitting to the at least one base station (400) of the wireless network (900) the time protocol message according to a Quality of Service, QoS, flow for transporting the time protocol message in the wireless network (900). The QoS flow is unambiguously or uniquely associated with at least one of the PDU session and the time protocol.

A traffic scheduling method includes determining, by a first network device, first traffic scheduling information and a transmission path of a first data stream based on a first talker attribute message received from a talker device and a listener attribute message received from a listener device, and then sending, by the first network device, a first traffic scheduling message to a network device on the transmission path. The first traffic scheduling message includes the first traffic scheduling information. The first traffic scheduling information indicates the network device on the transmission path to generate a gate control list. The gate control list indicates the network device on the transmission path to control, based on the gate control list, a state of a port used to transmit the first data stream.
