| Zusammenfassung: | The invention discloses a route maximal transmission unit changing method and a system in a generic routing encapsulation tunnel, which is characterized in that a data source can be dynamically notified to change a route maximal transmission unit of a link when the length of a data message of the data source after the generic routing encapsulation tunnel is encapsulated exceeds the maximal transmission unit of a tunnel interface. The route maximal transmission unit changing method and system support the dynamic changing of a route minimal unit of two types including an IPv4 (internet protocol version 4) generic routing encapsulation tunnel and an IPv6 (internet protocol version 6) generic routing encapsulation tunnel, so that the flow for data fragmentation of the data message exceeding the route maximal transmission unit can be avoided, the data forwarding efficiency is improved, a flexible fault notifying mechanism is achieved, the network management personnel can be notified in time when the data source do |
