摘要
The invention includes methods for controlling transmission of a plurality of packets from a sending device to a receiving device. A first method includes determining an expected path for a packet having associated with it a packet size, determining a Media Transmission Unit (MTU) size for the expected path, and, in response to a determination that the packet size is greater than the MTU size, propagating to the sending device a message adapted to reduce packet sizes of subsequent packets to be less than or equal to the MTU size. Other methods include generating a link state advertisement (LSA) for a link including a link TLV having a sub-TVL conveying MTU information associated with the link, transmitting the LSA toward a router, receiving the LSA at the router, and updating a table entry associated with the link using the MTU information conveyed by the sub-TLV.
