Problems solved by technology

The direct address lookup method consumes a huge amount of memory; the hash algorithm has two problems: one is that there are hash conflicts, and the other is that when the number of supported connections is particularly large, it also requires a huge memory space, and in this case , the probability of a hash collision also increases
[0007] However, the above-mentioned technical solutions still have the defect that the search speed is not fast enough to support arbitrary VPI / VCI digits, and further improvement is still needed

Embodiment Construction

[0026] The basic idea of ​​this method is to divide the entire VPI / VCI space to be managed into several equal intervals, and the size of each interval can be set according to the actual situation. In actual operation, when a certain VPI / VCI is used, the ATM system applies for the section where the VPI / VCI is located in the memory. In this way, the memory space of the entire ATM system is greatly saved, thereby improving the space utilization efficiency of the memory on the basis of ensuring time efficiency.

[0027] The above VPI space refers to the value space of all VPIs to be managed. Assuming that the supported VPI digits are 8 bits, the VPI space is 0 to 255; the VCI space refers to the value space of all VCIs to be managed. Assuming the supported VCI digits If it is 12 bits, the VCI space is 0 to 4095; the VCI BIT pool is the memory space applied for when virtual connection management is implemented, and each BIT in the memory space corresponds to a pair of VPI / VCI value...

Abstract

The invention provides a method for dynamically managing virtual connection in an asynchronous transfer mode (ATM). The method divides entire virtual path identifier (VPI) / virtual connection identifier (VCI) space into a plurality of equally divided intervals, and the size of the interval is set according to actual applications. During the actual operation, the ATM system applies memory for the space where only the VPI / VCI locate in a way of continuously pointing via a multi-level pointer only when a certain VPI / VCI are used, so as to remarkably save the memory of the entire ATM space and improve the space service efficiency of the memory on the premise that the time efficiency is ensured.

Description

technical field [0001] The invention relates to a method capable of dynamically managing virtual connections used in ATM (Asynchronous Transfer Mode, asynchronous transfer mode), and belongs to the technical field of broadband communication. Background technique [0002] ATM is a new data transmission mode developed on the basis of traditional circuit transmission mode and packet transmission mode. In this mode, data is organized into 53-byte cells (48 bytes of which are valid information, 5 bytes are headers or cell headers, and the headers store information on transmission addresses, etc.), Then perform fast packet switching to meet the needs of different business transmissions. Since each cell does not need to appear periodically, this data transmission mode is called asynchronous transmission mode. The "asynchronous" here means that the signal from the sender does not need to be sent at a certain pace (synchronous). ATM technology has the characteristics of fast trans...
