Abstract： |
The invention is an IP transmitting method supporting the differentiation of service quality extension of service band, and its characteristic: it adopts a method of inserting restriction code expressed by altogether 8 binaries and restriction type in IP packet head to make IP head extension at router end of network entrance, marks the service type of the packet head to the TOS domain of the packet head according to manager-arranged packet IP type rule list, and uses absolute priority controlling policy in output queue of a node; it modifies the condition value of each restriction in the middle router in transmission path and composes an IP packet head with modified service quality mark to make one-down jump transmission of this IP packet head; it deletes extended field of the service quality from the router of the network entrance and composes an ordinary IP packet head and sends this ordinary IP packet head to receiving end. It has the advantages of supporting both service differentiation and service quality routing, easy to implement without modifying terminal software. |
