摘要： Provided are methods and systems for processing data packets in a data network using a policy-based network path. The method may commence with receiving the data packet associated with a service session from a client. The method may continue with determining data packet information associated with the data packet. The method may further include determining the policy-based network path for the data packet based on the data packet information and one or more packet processing criteria. The method may continue with routing, based on the determination of the policy-based network path, the data packet along the policy-based network path.

摘要： Provided are methods and systems for distributing service sessions from a client device in a service data network. A packet of the service session is received by a forwarding node. The forwarding node determines whether the packet matches a service address associated with the service session. Responsive to the determining, a servicing node associated with the service address is selected based on a forwarding policy. The packet is sent to the selected servicing node. The servicing node determines whether the packet is a service request packet. A server is selected based on a service policy, wherein the server is configured to serve the service session. The packet is sent to the server. Before being received by a forwarding node, the packet is received by a gateway node. The gateway node determines whether the packet matches the service address and selects the forwarding node based on a notification.

摘要： Facilitation of secure network traffic by an application delivery controller is provided herein. In some examples, a method includes: (a) receiving a data packet with information from a client indicating that the client is a trusted source; (b) embedding in the data packet a transmission control protocol (TCP) options header, the TCP options header comprising information including at least a sequence number for a protocol connection; and (c) forwarding the embedded data packet to a server.

摘要： In providing packet forwarding policies in a virtual service network that includes a network node and a pool of service load balancers serving a virtual service, the network node: receives a virtual service session request from a client device, the request including a virtual service network address for the virtual service; compares the virtual service network address in the request with the virtual service network address in each at least one packet forwarding policy; in response to finding a match between the virtual service network address in the request and a given virtual service network address in a given packet forwarding policy, determines the given destination in the given packet forwarding policy; and sends the request to a service load balancer in the pool of service load balancers associated with the given destination, where the service load balancer establishes a virtual service session with the client device.

摘要： Provided are methods and systems for graceful scaling of data networks. In one example, an indication of removal of a node from a plurality of nodes of the data network is received. A service policy is generated to reassign service requests associated with the node to another node in the plurality of nodes. The service policy is then sent to each of the plurality of nodes of the data network. To scale out a data network, an indication of presence of a further node in the data network is received, and a further node service policy is generated and sent to each of the plurality of nodes of the data network and to the further node. Additional actions can be taken in order to prevent interruption of an existing heavy-duty connection while scaling the data network.

摘要： Provided are methods and systems for recognizing network devices as trusted. A system for recognizing network devices as trusted may include a network module, a storage device, and a processor. The network module may be configured to receive a request from a network device to establish a data connection between the network device and a server based on a determination that the network device is trusted. The storage device may be configured to store a whitelist associated with a plurality of trusted network devices. The processor may be configured to determine that the network device is trusted. Based on the determination, the processor may associate the network device with the whitelist for a predetermined period of time.

摘要： Provided are methods and systems for dynamically distributing a service session from a client device. The method may commence with receiving a packet associated with the service session from the client device by a gateway node. The method may include determining that the packet matches a service address in a forwarding policy. The method may continue with selecting one of a plurality of forwarding nodes for sending the packet to the one of the plurality of forwarding nodes. The method may include receiving the packet of the service session by the one of the plurality of forwarding nodes. The method may continue with determining that the packet matches the service address serviced by a servicing node of a plurality of servicing nodes. The method may further include sending the packet to the servicing node for forwarding the packet to a server by the servicing node.

摘要： Provided are methods and systems for eliminating a redirection of data traffic in a cluster. An example method may include receiving, by one or more nodes of the cluster, a data packet associated with a service session. The method may include determining, by the node, that the data packet is directed to a further node in the cluster. The method may further include, in response to the determination, acquiring, by the node, a session context associated with the service session. Acquiring the session context may include sending, by the node, a request for the session context to the further node and receiving the session context from the further node. The method may further include processing, by the one or more nodes, the data packet based on the session context.
