    摘要： A device receives traffic; identifies an address associated with the traffic; determines whether the address is associated with an aggregate interface, the aggregate interface being associated with a first port and a second port. The first port corresponds to a first node in a first state, that indicates that the first node is available to forward the traffic, and the second port corresponds to a second node in a second state, that indicates that that the second node is not available to forward the traffic. The device transmits the traffic to the first node via the first port and to the second node, via the second port, when the address is associated with the aggregate interface. Transmitting the traffic enables the second node to forward the traffic when the first node changes from the first state to the second state.

    摘要： This disclosure is directed toward an integrated switching and routing security device that provides zone-based security directly between layer two (L2) interfaces of L2 bridge domains and/or layer three (L3) interfaces of L3 routing instances within the security device. The integrated switching and routing security device supports both switching and routing functionalities for packets on L2 and L3 interfaces, and supports security within and between L2 bridge domains and L3 routing instances. The integrated switching and routing security device configures L2 security zones for one or more L2 interfaces and configures L3 security zones for one or more L3 interfaces. The integrated switching and routing security device then applies security policies to incoming packets according to the L2 security zones and/or the L3 security zones associated with the incoming interface and an outgoing interface for the packets to provide end-to-end security within the security device.

    摘要： In general, techniques are described for dynamically managing weighted queues. In accordance with the techniques, a network security device comprises a queue management module that assigns, for each queue of a plurality of queues, a quota desirable to a user that a processor of the network security device consumes to service each queue. The queue management module determines, based on the desirable quotas, a queue weight for each queue and computes. Based on the computation, the queue management module dynamically adjusts one or more of the weights such that subsequent amounts of processing time actually required to process the number of packets defined by each of the queue weights more accurately reflects the desirable quotas assigned to each of the queues. The network device outputs the number of packets in accordance with the adjusted weights.

    摘要： A method may be performed by a device in a network, the device including multiple security process units (SPUs). The method includes receiving a packet over the network, the packet including a media access control (MAC) address, and assigning one SPU as the MAC address owner. The method also includes sending information about the MAC address to other SPUs within the device, storing the MAC address in a MAC table within each SPU, and initiating a MAC age query to confirm the MAC address has timed out among all SPUs. The MAC age query is passed via a logical ring of the SPUs beginning with the MAC address owner. If the MAC address is aged out at each SPU, the MAC address is deleted from each MAC table. If the MAC entry is still active, a different SPU is assigned as the MAC address owner.

    摘要： An integrated security switch and related method for managing connectivity and security among networks. The integrated security switch includes a security function connectable with a first network and at least one switching function connectable with a second network. A common management interface driven by both command line interface and graphic user interface protocols manages the switching function via a management path dedicated between the security function and the switching function. The common management interface enables secure switching of traffic to flow via a traffic path dedicated between the switching function and the security function. Typically, the traffic is a flow of data between the Internet and a group of networked users such as a wide area network.

    摘要： A method is disclosed for providing security to a client-to-client communication. The method includes authenticating a first client and a second client with an access point device, transmitting the packet to the security device and modifying a destination media access control (MAC) address of a packet from the first client to a MAC address of a security device for a first network. The packet contains a destination internet protocol (IP) address of the second client. The access point device and the first and second clients belong to the first network. The security device is located between the first network and a second network.
