摘要:
A method and system for learning network information through a plurality of network devices is provided. The plurality of network devices are configured for IPsec. The method enables negotiation between the network devices to set up a security association and provide network information between the configured network devices. This network information includes a plurality of sub-network routes.

Upon detection of a new traffic flow, a registration node can dynamically register the new traffic flow with a key server policy manager by sending a registration request on behalf of the new traffic flow. A registration request indicates the new traffic flow should be protected by a security group. A registration request may also include a request to dynamically generate a new security group to protect the traffic flow. The registration request is received by a key server policy manager, which performs authentication and authorization checks of the requesting registration node, and determines whether to accept or reject the registration request. If accepted, the key server policy manager registers the new traffic flow by including a description of the traffic flow in a group policy of an existing security group or a newly created security group, depending on the registration request.
摘要:
Network devices can detect whether a tunnel is available (e.g., usable to convey traffic in both directions) by implementing a tunnel detection protocol that uses a combination of idle timers and multiple types of probes. In this protocol, the device at one end of the tunnel is configured as an active device, while the device at the other end of the tunnel is configured as a passive device. The tunnel detection protocol is asymmetric; the active device sends probes to the passive device, but the passive device does not send probes to the active device. By using at least two types of probes, the active device can inform the passive device about the availability of the path from the passive device to the active device. Since the passive device does not need to send probes or process probe replies, control plane processing on the passive device can be reduced.

A system transmits, to a hub from a first spoke, first routing information associated with the first spoke. The system receives, at the first spoke, from the hub, second routing information associated with a plurality of spokes in communication with the hub. The plurality of spokes includes a second spoke. The system resolves, at the first spoke, a next hop determination for the packet based on the second routing information received from the hub. The system routes the packet from the first spoke to the second spoke using the next hop determination.

In one embodiment, a QoS manager process that receives, at an EzVPN server device, connection speed data from an EzVPN client device. In addition, the QoS manager process processes, at the EzVPN server device, the connection speed data to determine a QoS policy for a communications session between the EzVPN client device and the EzVPN server device. Furthermore, the QoS manager process applies, at the EzVPN server device, the QoS policy to the communications session between the EzVPN client device and the EzVPN server device as determined by the processing of the connection speed data.
摘要:
A system and method directed to carrying out dynamic secured group communication is provided. The method includes: obtaining a first packet that includes a first header; forming a frame that includes the first header in encrypted form; combining the first header and the frame to form a second packet and forming a second header; encapsulating the second packet with the second header to form a third packet, and communicating the third packet into the second network from the second source node for termination to the second-destination node. The first header includes a first source address of a first source node of a first network, and a first destination address of a first destination node of the first network. The second header includes a second source address of a second source node of a second network, and a second destination address of a second destination node of the second network.
