By extending the functions of RSVP-TE

a new mechanism of failure notification based on serial communication and same source was proposed. Since serial communication mechanism was introduced

it could achieve failure notification according to source of connections affected by failure

and made contribution to failure recovery rate and failure recovery time. Experiments were implemented in a 15-node-ASON test-bed. And the results show that

compared with traditional failure notification mechanism

the new mechanism can avoid the conflicts of resource reservation in the process of network failure recovery to a certain degree. With this new mechanism

network failure recovery rate is effectively increased by 21% and network failure recovery time is shortened by 15% in the testing network with 5 000 connections.
