Problems solved by technology

However, the IP network based on packet switching is a non-connection, unreliable, and best-effort network technology. In the existing packet ring, there is no resource reservation function, and it is impossible to guarantee services with high real-time requirements.
[0007] However, if a resource reservation method similar to the above-mentioned timeslot-based resource reservation method is used in the packet ring, because the flow of data packets is bursty, if the total flow is less than one or more fixed bandwidths allocated, then its idle bandwidth Resources cannot be utilized by other nodes
In other words, there is a certain waste of bandwidth for data packets that can be statistically multiplexed

Embodiment Construction

[0042] The core of the present invention is to divide the grouping ring into a plurality of virtual channels from the source node to the destination node, and use them as transmission channels for reserved resource messages. At the same time, after removing the bandwidth actually used by the reserved resource virtual channels, The remaining bandwidth is used as a shared virtual channel to be shared by all nodes, that is to say, the virtual channel is used in the packet ring to realize the reserved bandwidth resources, and statistically multiplex the remaining bandwidth.

[0043] Those skilled in the art know that in many applications, it is necessary to establish a channel with a fixed bandwidth between the nodes of the ring network to transmit services with high real-time requirements, such as VoIP, TDM (time division multiplexing) simulation, dedicated line bandwidth and Video services, etc. have high real-time requirements. In order to ensure the transmission quality and red...

Abstract

This invention discloses a method of reserving resource in the group loop. Said group loop comprises several nodes and the physics chain circuit connecting the adjacent nodes, wherein every node can be the resource node of the upper ring business or the objective node of the lower ring business. The method comprises the following steps: a) dividing the group loop into several void channels from the resource node to the objective node as the communication channel of the reserving resource message; b) when the reserving resource message needs passing the group loop transmission, bearing to the corresponding void channel; c) using the rest belt width after bearing the reserving resource message as the sharing channel, bearing other group message needs transmitting from the group loop. By said method, it can preserve the bandwidth of the reserving resource, and makes the other bandwidth being used again.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing resource reservation on a packet ring. Background technique [0002] At present, in order to achieve reliable transmission of telecommunication services and save optical fiber resources, ring network structures are usually used to provide primary and backup links. Most ring networks are based on SDH / MSTP (Synchronous Digital Hierarchy / Multi-Service Transmission Platform). The feature is that it adopts a double-ring structure, one working ring and one backup ring. When the fiber segment of one ring fails, it is guaranteed to switch to the backup ring within 50ms. This ring network is widely used in communication networks that require high reliability to ensure that communication services will not be interrupted. [0003] This ring network is based on the time division multiplexing method, and can realize the resource reservation function based...
