Abstract

PURPOSE:To decrease 9 data transfer delay time by adopting the constitution such that the same outgoing line is being selected while the length of an outgoing line queue is monitored for the packet transmission so long as a packet data does not exceed the content of two prescribed queues or over. CONSTITUTION:A multi-link frame is sent to outgoing lines 105 - 107 through line selection wait queues 102- 104 from a packet module 100. When a packet data is sent to either of the queues 1-3,104, the queue 102 is selected so long as the data does not exceeds the content of the 2 prescribed queues or over and the data is sent to the outgoing line 105. Thus, the wait time of the rearrangement of the sequential numbers at the frame reception side is not caused and the excess of the data processing time for realizing the function of rearranging the sequential numbers is not caused.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はパケット交換プロトコルマルチリンク制御手順
における出回線選択方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an outgoing line selection method in a packet switching protocol multilink control procedure.

〔従来の技術〕[Conventional technology]

従来、出回線選択方式として一義的な順序選択方式もし
くは最短待ちキュー長値の回線を選択する選択方式があ
る。Conventionally, as an outgoing line selection method, there is a unique order selection method or a selection method that selects the line with the shortest waiting queue length value.

るという問題がある。In the case of the conventional order selection method and shortest queue length line selection method described above, the line selected is different for each frame, and the frame receiving side has to wait to rearrange the order numbers. There are problems in that it takes time and additional data processing time is required to realize the function of rearranging the sequence numbers.

Outgoing lines 105, 106, 107 through 103.104
This figure shows how the data is sent. Here, when packet data is sent to either of the line sending waiting queues 103, 104, as long as there are a certain number (for example, 2) and the queue length does not exceed a certain value, the packet data is sent to either of the line sending waiting queues 103, 104. 102 is selected and sent to the outgoing line 105.

る。As explained above, according to the present invention, when selecting an outgoing line in a packet switching protocol multilink control procedure,
The queue length for each output line for sending packets is monitored, and the same output line is selected from among multiple output lines as long as there are multiple queue lengths and the queue length does not exceed the specified queue length. By continuing to do so, data transmission delay time can be reduced.
