流氓數(shù)據(jù)包刪除操作流氓數(shù)據(jù)包是指不屬于網(wǎng)絡(luò)上任何節(jié)點的數(shù)據(jù)包?；貞浄瓷鋬?nèi)存的基本操作，一個節(jié)點在網(wǎng)絡(luò)上發(fā)起一個數(shù)據(jù)包RADISYS EXP-BP3A EXPBP3A，以響應(yīng)來自主機的內(nèi)存寫入。數(shù)據(jù)包在網(wǎng)絡(luò)周圍傳輸?shù)剿泄?jié)點，直到它返回到始發(fā)節(jié)點。然后，始發(fā)節(jié)點需要將分組從網(wǎng)絡(luò)中移除。

然而，如果數(shù)據(jù)包在通過另一個節(jié)點時以某種方式被更改，或者如果始發(fā)節(jié)點開始出現(xiàn)故障，則始發(fā)節(jié)點可能無法將數(shù)據(jù)包識別為自己的數(shù)據(jù)包，RADISYS EXP-BP3A EXPBP3A并且不會將數(shù)據(jù)包從網(wǎng)絡(luò)中移除。在這種情況下，數(shù)據(jù)包將繼續(xù)在網(wǎng)絡(luò)中傳遞。

流氓包極為罕見。它們的存在表明，由于真正的組件故障或在惡劣環(huán)境中操作，導(dǎo)致了板故障。通常情況下，解決方案是隔離和更換故障板和/或改善環(huán)境。然而，一些用戶更喜歡容忍零星的流氓數(shù)據(jù)包，而不是在流氓數(shù)據(jù)包從網(wǎng)絡(luò)中刪除的情況下停止系統(tǒng)進行維護。RADISYS EXP-BP3A EXPBP3A

英文資料：

Rogue Packet Remove Operation A rogue packet is a packet that does not belong to any node on the network. Recalling the basic operation RADISYS EXP-BP3A EXPBP3Aof Reflective Memory, one node originates a packet on the network in response to a memory write from the host. The packet is transferred around the network to all nodes until it returns to the originating node. It is then a requirement of the originating node to remove the packet from the network.RADISYS EXP-BP3A EXPBP3A

If, however, the packet somehow gets altered as it passes through another node or if the originating node begins to malfunction, then the RADISYS EXP-BP3A EXPBP3Aoriginating node may fail to recognize the packet as its own and will not remove the packet from the network. In this case the packet will continue to pass around the network.

Rogue packets are extremely rare. Their existence indicates a malfunctioning board due to true component failure or due to operation in an harsh environment. Normally, the solution is to isolate and replace the malfunctioning board and/or improve the environment. However, some users prefer to tolerate sporadic rogue packets rather than halt the system for maintenance provided the rogue packets are removed from the network.RADISYS EXP-BP3A EXPBP3A
