The present invention provides a detection method used for transmission bandwidth detection in multi-level transmission bandwidth assurance, including: detecting, by at least two transmission bandwidth detection units, a transmission bandwidth of a transmission link; where each transmission bandwidth assurance level in the multi-level transmission bandwidth assurance is corresponding to only one of the at least two transmission bandwidth detection units, and when the transmission link operates at a first transmission bandwidth assurance level, a first transmission bandwidth detection unit corresponding to the first transmission bandwidth assurance level detects the transmission bandwidth of the transmission link.

Detection method, device, and system

Embodiments of the present invention provide a data processing method, including: obtaining, by a receiving device, a first data packet sequence; determining, according to an identifier of a data packet in the first data packet sequence, an identifier of a data packet lost in a transmission process of the transmission system; determining an estimated value of the lost data packet according to a value of the data packet in the first data packet sequence; combining the value of the data packet in the first data packet sequence with the estimated value of the lost data packet as a second data packet sequence corresponding to the source data packet sequence; and performing digital signal processing on the second data packet sequence.

Data processing method and receiving device

A variation of a packet gap between packets sent from a source node and a packet gap between packets received by a destination node is determined; then an intensity of the packet gap variation is determined; and finally whether transmission congestion occurs between the source node and the destination node is determined according to the intensity of the packet gap variation. Therefore, accuracy of identifying a cause of a packet loss is improved, thereby avoiding impact of a transmission bit error.

Method, apparatus, and system for packet loss detection

A method for determining a transmission buffer size, including acquiring a transmission delay of a data packet that is sent by a transmit end on a transmission link between the transmit end and a receive end, updating a minimum transmission delay according to the transmission delay and based on a first update period when a primary congestion status of the transmission link is congested, updating the minimum transmission delay according to the transmission delay and based on a second update period when the primary congestion status is non-congested, where a period length of the first update period is shorter than a period length of the second update period, obtaining a minimum transmission delay of the transmission link, and determining a transmission buffer size of the transmission link according to the transmission delay and the minimum transmission delay.

Method and device for determining transmission buffer size

The present invention relates to an IP address automatic assignment method, a client, and a server. The present invention solves the technical problem in the prior art that a DHCP Relay host needs to be added additionally to assign an IP address to a client when a DHCP server and the client are not on the same network segment, thereby saving configuration cost and simplifying network configuration.

IP address automatic assignment method, device, and system

A method of the present invention includes: determining, when packet congestion occurs or network bandwidth decreases, at least one to-be-discarded packet in a packet buffer; and discarding the at least one to-be-discarded packet so that at least one unbuffered packet enters the packet buffer to prevent discarding too many unbuffered packets, where the unbuffered packet is a packet that has not entered the packet buffer. The present invention is primarily applied in a packet buffering process.

Packet transmission method and apparatus

A method and an apparatus for obtaining a remote Internet Protocol (IP) address are provided. The method includes: receiving, by a first client, a first detection IP packet from a remote server through a Point to Point Protocol (PPP) interface, in which the first detection IP packet carries a first IP address allocated by the remote server for the first client; and configuring the first IP address to be an IP address of the first client. Through the method and the apparatus, the remote server is capable of allocating a remote IP address of a client.

Method and apparatus for obtaining remote IP address

The present invention provides a method and a device for determining timeslot configuration in TDM transmission. The method includes: receiving consecutively transmitted TDM frames, wherein at least one TDM frame among the consecutively transmitted TDM frames includes a characteristic word; and according to a case of a timeslot collection occupied by the characteristic word in the TDM frame, determining a timeslot collection configured in the TDM frame for HDLC frames, wherein the characteristic word is configured to match a physical layer rate when no peer-peer protocol, PPP, link setup request packets are transmitted. Embodiments of the present invention are able to realize automatic acquisition of timeslot configuration of TDM frames.
