Dword(双字=4字节)传输速率从43 MByte/s的非冗余速率下降到大约20 MByte/s。16字(64字节)传输速率从170 MByte/s的非冗余速率下降到85 MByte/s的冗余速率。操作原理30 2.8流氓数据包移除操作流氓包是不属于网络上任何节点的数据包。回顾反射存储器的基本操作,一个节点在网络上发起数据包,以响应来自主机的存储器写入。数据包在网络周围传输到所有节点,直到它返回始发节点。要求始发节点从网络中移除分组。然而,如果分组在通过另一个节点时被错误地改变,或者如果始发节点开始故障,则始发节点可能无法将分组识别为自己的分组,并且不会将其从网络中移除。在这种情况下,数据包将继续作为“流氓数据包”在网络中传播。当连接到5595集线器时打开或关闭节点电源时,可能会创建恶意数据包。连接或断开光缆时也可能发生这种情况。如果网络中的任何节点溢出网络FIFO,则可能会创建恶意数据包。Dword (Double‐word = 4 bytes) transfer rate drops from the non‐redundant rate of 43 MByte/s to approximately 20 MByte/s. The 16 Dword (64 byte) transfer rate drops from the non‐redundant rate of 170 MByte/s to the redundant rate of 85 MByte/s. Theory of Operation 30 2.8 Rogue Packet Removal Operation A rogue packet is a packet that does not belong to any node on the network. Recalling the basic operation of 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 a requirement that the originating node remove the packet from the network. If, however, the packet is erroneously altered as it passes through another node, or if the originating node begins to malfunction, then the originating node may fail to recognize the packet as its own and will not remove it from the network. In this case, the packet will continue to traverse the network as a “rogue packet.” Rogue packets are extremely rare. A rogue packet could be created when turning a node’s power on or off while connected to a 5595 Hub. It could also occur when connecting or disconnecting fiber cables. A rogue packet might be created if any node in the network overflows a network FIFO.
