System and method for guaranteeing quality of service in IP networks
First Claim
1. A system for guaranteeing quality of service with respect to packets transmitted/received between an external network capable of providing differentiated services and a home network, comprising:
- a packet classifier for classifying the packets according to addresses and traffic types;
a marker for allocating information on priorities to packets transmitted from the home network to the external network;
a priority class queue having a plurality of queues classified according to the priorities;
a scheduler for servicing packets stored in the priority class queue according to the priorities; and
a token bucket for dropping packets, bandwidths of which are above a preset maximum bandwidth, when the packets are generated.

Abstract
The system of the present invention guarantees quality of service with respect to packets transmitted/received between an external network capable of providing differentiated services and a home network. The system includes a packet classifier, a marker, a priority class queue, a scheduler and a token bucket. The packet classifier classifies the packets according to addresses and traffic types. The marker allocates information on priorities to packets transmitted from the home network to the external network. The priority class queue has a plurality of queues classified according to the priorities. The scheduler services packets stored in the priority class queue according to the priorities. The token bucket drops packets, bandwidths of which are above a preset maximum bandwidth, when the packets are generated.
