Description
Technical field
The present invention relates to MPLS (multiprotocol label switching) network field more particularly to a kind of layering QoS of resource multiplex
Implementation method and device.
Background technique
HQoS (Hierarchical Quality of Service is layered QoS), by the way that scheduling strategy is assembled ingredient
The mode of the tree of level realizes the purpose of layering scheduling.Due to using tree, scheduling node and scheduling queue
Consumption it is bigger.
And the protection technique in MPLS network, in order to preferably ensure client traffic, when operating path when something goes wrong, lead to
The method for switching the business to Protection path is crossed, to reach the unbroken purpose of business.Protection is divided into the protection of pseudo-wire grade, tunnel
Grade protection and the protection of section layer.If pseudo-wire, tunnel, tomography enable protection, 8 possible paths, 1 work at most will form
Make path, 7 Protection paths.
If enabling layering QoS in the pseudo-wire of Protection path or tunnel, just schedule tree is established using when establishing path
Mode, then the consumption for dispatching resource is up to original 8 times compared to the case where protection is not configured.Scheduling node and
The resource of scheduling queue is originally limited, and so a large amount of consumption necessarily causes the pseudo-wire supported, the quantity in tunnel to reduce, in turn
The number of services of support is also reduced, the overall performance index decline of final equipment.
