各位通訊界的大大們,請幫忙翻譯,謝謝!(8)

請一句一句翻譯,在英文下直接寫上中文,感激不盡!

If a node detects a break during data forwarding (Phase

II), it repairs it by broadcasting a LSP, which includes the

last advertisement sequence number it used and QoS

parameters. Processing of the local self-healing messages

is similar to Phase I. The only exception is the technique

that a node employs to determine if it is downstream for

the node that initiated the repair. If a node has received an

advertisement packet from the node that initiated the route

repair with an advertisement sequence number that

matches the one in the LSP, it knows that it is downstream

from the node that initiated route repair.

To reduce the overhead that is caused by the

advertisement messages, two optimization techniques can

be employed. In the first technique, the advertisement

message is piggybacked with data packets. In the second

technique, when a node receives an advertisement packet

from an upstream node, it appends its message to it before

forwarding the packet and then resets its advertisement

timer. The advertisement timer in the nodes can be

adjusted according to node movements. To limit the

distances that the LSP messages travel during route repair,

their TTL fields can be set to a small value, such as 5, and

repeatedly increased until a the route is repaired or the

value reaches a certain threshold, such as the distance

between the node and D.
