Problems solved by technology

The disadvantage of this method is that it can only be used for the transmission of data streams based on packet streams, not for byte streams.
At the same time, it does not support multi-service data streams

Embodiment Construction

[0028] At present, the network interface provided by the Leased Line transmission system (including SDH, PDH, ATM) in the public network is usually E1 / T1, and the bandwidth is 2Mbps or 1.5Mbps. The present invention is a scheme that can provide data with a bandwidth greater than 2Mbps (1.5Mbps for T1) and less than 8Mbps (6Mbps for 4 T1s), and use multiple E1 / T1 interfaces to transmit in the transmission network.

[0029] The present invention splits the service data stream to be transmitted into multiple N-byte data segments at the sending end, and adds header information in front of it to form a data segment including header information (hereinafter referred to as reverse Multiplexing frame), the inverse multiplexing frame is sent to the receiving end through one of the multiple E1 / T1 interfaces through a scheduling algorithm; the header information includes the sequence number of each data segment. At the receiving end, the inverse multiplexing frames received from each E1 / ...

Abstract

The invention discloses a Multi-network interface inverse multiplexing method , which including the following steps: 1) the transmitter will split the transmission of business data bitstream into a number of N bytes of data in which an additional serial number with the head of the information be attached, and using the scheduling algorithm send the various data including the head information through the multi-channel interface of E1 / T1 all the way to the receiver; 2) receiver extracted the head information of the serial number from data through various E1 / T1 interface , and data stream after sorting the business data bitstream. This invention can realize multiple network interface data transfer at the same time and meet the high bandwidth utilization, suitable for a variety of business bitstream and transmission interruption will not happen.

Description

technical field [0001] The invention relates to a method for transmitting data by using multiple network interfaces, that is, a method for inverse multiplexing of multiple network interfaces. Background technique [0002] For the process of using multiple network interfaces to transmit data, the ideal state is to achieve the following three points: first, the bandwidth utilization rate is high; second, it is suitable for a variety of business streams; third, there will be no stream interruption during transmission. [0003] There are two main methods of inverse multiplexing of existing multi-network interfaces: [0004] The first method is divided into two steps: the first step is to negotiate through signaling to determine the order of network interfaces and the relative delay of each network interface; Send the negotiation information; and receive the service data streams of multiple network interfaces according to the order of the network interfaces determined in the fir...
