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： 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： 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. Nodes in a cluster may communicate between with each other over a dedicated backplane, which may be a separate physical medium.

摘要： Described herein is a method and system for distributing whole and fragmented requests and responses across a multi-core system. Each core executes a packet engine that further processes data packets and data packet fragments allocated to that core. A flow distributor executing within the multi-core system forwards client requests to a packet engine on a core that is selected based on a value generated when a hash is applied to a tuple comprising a client IP address, a client port, a server IP address and a server port identified in the request. The packet engine maintains each element of the tuple and forwards the request to the selected core. The packet engine can also process data packet fragments by assembling the fragments prior to transmitting them to the selected core, or by transmitting the data packet fragments to the selected core.

摘要： The present invention is directed towards forwarding network packets in a cluster network. A predetermined identifier may be inserted into a Media Access Control (MAC) ID field of an Ethernet header of a packet to distinguish various types of traffic. Newly received packets may be identified due to the absence of the identifier. The identifier may be added to the source MAC ID field of the Ethernet header of the packet, and the packet may be distributed to cluster nodes for processing via an inter-node communication bus. Thus, received packets with the identifier in the source MAC ID field may be identified as steered for processing by an internal node of the cluster. After processing the packet, the internal node may transmit the processed packets via the inter-node bus with a destination MAC ID including the identifier.
