Problems solved by technology

If the waiting time on the TDMA network will change with the network topology, that is, the average waiting time of the nodes in the TDMA network is a function of the node position, then the optical fiber TDMA network will be inherently accompanied by the problem of unfair distribution of access rights. indivisible

Embodiment Construction

[0024] For a TDMA network, a node that wants to transmit information must first send a "transmission request" to notify the entire network to reserve a free slot. The number of reserved free slots corresponds to the number of sent "transmission requests". When the number of reserved idle slots increases, the average waiting time of nodes will decrease accordingly. Therefore, if a node has higher traffic, its average waiting time will be smaller. If the average waiting time of a TDMA node is used as a criterion for evaluating the slot access rights it has, then the nodes that generate a larger amount of traffic will have more access rights. In other words, TDMA nodes compete with each other according to the amount of traffic they generate, so as to gain access to the media. The relationship between the average waiting time of a TDMA node and its node traffic can be derived as follows.

[0025] The derivation of the average waiting time of TDMA nodes is based on three network...

Abstract

The invention relates to a time-division multiple access method of an optical fiber network media and a traffic control mode applied to same. The time-division multiple access method is mainly characterized in that an MAC (Medium Access Control) protocol carries out access control on network nodes using a same optical fiber by adopting the traffic control mode so that the access right of the network nodes on optical fiber bandwidth can be effectively and reasonably distributed among the nodes so as to solve the problem of inequitable distribution of the access right of the time-division multiple access of an optical fiber network and promote the optical fiber network to be suitable for establishing various application networks, such as a metropolitan area network, a local area network or a subnetwork of a public network, and the like, thereby reducing the cost of network construction and enhancing wideband utilization ratio.

Description

technical field [0001] The present invention relates to a time-division multiple access method for optical fiber network media and its application traffic control method. Improve the problem of unfair distribution of node bandwidth access rights in optical fiber networks, and promote time-division multiple access optical fiber networks to be suitable for constructing local area networks, intercity networks or sub-networks of public networks, etc., to reduce network construction costs and improve broadband usage Rate. Background technique [0002] According to the Hartley-Shannon theorem (channel / information capacity theorem), the channel capacity of a transmission medium is limited by the bandwidth and signal-to-noise ratio of the transmission medium used. A transmission medium with high bandwidth and high signal-to-noise ratio naturally has a large channel capacity. Comparing the two transmission media of stranded wire and optical fiber, because the signal-to-noise of opt...
