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 application is directed towards sharing data link layer information of network traffic distributed across a cluster of intermediary devices. A method for sharing data link layer information across a cluster includes receiving a request packet at a first intermediary device. The first intermediary device identifies a first set of data link layer information from a data link layer of the request packet. The first intermediary device modifies the request packet for transmission on a common data backplane of the cluster to include the first set of data link layer information in the request packet. The modified request packet includes a second set of data link layer information that differs from the first set of data link layer information at the data link layer. The first intermediary device transmits the modified request packet on the common data backplane of the cluster to other devices of the cluster.

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.
摘要翻译： 本发明涉及在群集网络中转发网络分组。 可以将预定标识符插入到分组的以太网报头的媒体访问控制（MAC）ID字段中，以区分各种类型的业务。 由于不存在标识符，可能识别出新接收的分组。 标识符可以被添加到分组的以太网报头的源MAC ID字段中，并且分组可以被分发到群集节点以经由节点间通信总线进行处理。 因此，在源MAC ID字段中具有标识符的接收到的分组可以被识别为被集群的内部节点处理。 在处理分组之后，内部节点可以经由节点间总线传送经处理的分组，其中包括标识符的目的地MAC ID。

摘要： The present disclosure describes systems and methods for propagating port state to intermediary devices of a cluster in a static link aggregation environment. The methods and systems include a cluster comprising a plurality of intermediary devices in communication with a network device via a static link aggregation comprising aggregated ports from different intermediary devices of the cluster. A first device of the static link aggregation is configured to detect that a health of the first device is below a predetermined threshold and, responsive to the detection, identify one or more ports in the aggregated ports as down. A second device of the link aggregation is configured to, responsive to the identification, remove the ports from a distribution list for the static link aggregation. Upon detection that a health of a device is above a predetermined threshold, the first device may identify the ports as up.

摘要： In a cluster environment, nodes participating in the cluster may generate packets with the same source IP to the same destination IP. If those packets get fragmented down stream, then reassembling this packets depends on the source IP, destination IP, protocol and the IP identifier field (IPID) of the IP packet. As the source IP, destination IP and protocol may be fixed, the IPID generation is coordinated across the nodes to support reassembly down stream and avoid tuple collision. The IPID space may be equally split among the nodes in the cluster. Each node generates IPID within its range to avoid a collision with an IPID generated from another node.
