A METHOD AND A DEVICE FOR QOS GUARANTEE OF NETWORK DATAGRAMS TRANSPORTED IN DIFFERENT NETWORKS

摘要

A method and a device for QoS guarantee of network datagrams transported in different networks are provided. The method comprises the steps of: parsing a first network datagram and obtaining a first datagram priority when the first network datagram is transported from a first network to a second network; encapsulating the first network datagram into a second network datagram which contains a second datagram priority corresponding to the first datagram priority; transporting the second network datagram according to the second datagram priority in the second network. In this way, even if after being converted in different networks, original datagram priority is still kept and embodied. The QoS is guaranteed.
