摘要： While each node in a cluster of nodes sources connections with the same IP if each node allocates a port on this IP independently, there may be port clashes. Also, the return traffic is not guaranteed to hit the originating node. These issues are addressed by allocating a port in such a way that the response traffic hashes back to the originating node. A good hash is chosen such that the ports are equally divided among the nodes. When a node leaves, the other nodes take over the port range used by this node. When a node joins, the node takes back its share of ports.
摘要翻译：虽然节点集群中的每个节点都会以相同的IP源连接，如果每个节点分别在此IP上分配一个端口，则可能会有端口冲突。此外，返回流量不能保证打到始发节点。这些问题通过分配端口来解决，使得响应流量返回到始发节点。选择好的散列，使得端口在节点之间被等分。当节点离开时，其他节点接管该节点使用的端口范围。当节点加入时，节点将收回其端口份额。

摘要： In the present solution, when a cluster node sends an ARP request for an external IP, the node sends a message to all the other nodes, which are part of the CLAG to expect an ARP reply for the IP. When a node in the cluster receives the ARP reply, the node informs the other nodes which are part of the same CLAG to update the MAC address. Also when an ARP entry is learned/updated over a CLAG link as part of an ARP request/Gratuitous ARP, the node learning/updating the ARP entry will inform other nodes which are part of the same CLAG about the learned/updated ARP entry. Nodes in a cluster may communicate between with each other over a dedicated backplane, which may be a separate physical medium.
摘要翻译：在本解决方案中，当集群节点发送外部IP的ARP请求时，节点向所有其他节点发送消息，这些节点是CLAG的一部分，以期望IP的ARP应答。当集群中的节点接收到ARP应答时，节点通知作为同一CLAG一部分的其他节点更新MAC地址。另外，当作为ARP请求/免费ARP的一部分通过CLAG链路学习/更新ARP条目时，学习/更新ARP条目的节点将通知与学习/更新的ARP条目相同的CLAG的其他节点。集群中的节点可以通过专用背板彼此通信，专用背板可以是单独的物理介质。

摘要： The present application is directed towards systems and methods for distributing traffic across nodes of a cluster of intermediary devices through distributed flow distribution (DFD). Upon receipt of network traffic, a cluster node, such as an intermediary computing device or appliance, may internally steer a portion of the traffic via an inter-node communications backplane to one or more other nodes in the cluster so that the load is equally handled by all of the nodes in the cluster. A cluster node may determine whether to process the traffic steered via the backplane by computing a hash of packet parameters of the network traffic. Hash keys may be selected such that uniformity is assured, and the key used in hash computation may be synchronized across all of the nodes so that only one node determines that it should process the particular packets or traffic flow.

摘要： In the present solution, when a cluster node sends an Address Resolution Protocol (ARP) request for an external internet protocol (IP), the node sends a message to all the other nodes, which are part of the Cluster Link Aggregation (CLAG) to expect an ARP reply for the IP. When a node in the cluster receives the ARP reply, the node informs the other nodes which are part of the same CLAG to update the Machine Access Control (MAC) address. Also when an ARP entry is learned/updated over a CLAG link as part of an ARP request/Gratuitous ARP, the node learning/updating the ARP entry will inform other nodes which are part of the same CLAG about the learned/updated ARP entry.
