摘要:
The present disclosure provides solutions for an enterprise providing services to a variety of clients to enable the client to use the resources provided by the enterprise by modifying URLs received and the URLs from the responses from the servers to the client's requests before forwarding the requests and the responses to the intended destinations. An intermediary may identify an access profile for a clients' request to access a server via a clientless SSL VPN session. The intermediary may detect one or more URLs in content served by the server in response to the request using one or more regular expressions of the access profile. The intermediary may rewrite or modify, responsive to detecting, the one or more detected URLs in accordance with a URL transformation specified by one or more rewrite policies of the access profile. The response with modified URLs may be forwarded to the client.
摘要:
A network device that processes packets and includes at least one legacy component for performing basic processing on packets in the network device. The network device further includes at least one advanced component for performing advanced processing, which can not be performed by the legacy component, on packets in the network device. When an incoming packet to the legacy component requires advanced processing, the legacy component performs the basic processing and transmits the packet to a loop-back port on advanced component. Upon receiving the packet, basic processing is disabled on the advanced component and advanced processing is performed on the packet.
摘要:
A multicast engine is provided in plurality within a router for replicating and/or modifying packets identified as multicast packets. In preferred embodiments the engine is integrated with one or more ports of a router, particularly with one or more ports of fabric cards. In one implementation the multicast engine is associated with a table having instructions for replicating or modifying multicast packets received, and forwarding the packets accordingly.
摘要:
A distributed Link-State Routing Protocol (LSRP) system in a packet switch having external communication ports has a first card executing Update process of the LSRP, making database updates, a second card executing Decision process(Shortest Path First (SPF)) of the LSRP, and a communication fabric coupling the cards with each other and the external ports. The LSRP may be an IS—IS system. In some embodiments there are additional cards involved, and the distribution of Link-State functions is over a set of multiple cards. Also in some embodiments there is a Location Service (LS) controller monitoring and configuring cards in the system.
摘要:
The present application enables the enterprise to configure various policies to address various subsets of the traffic based on various information relating the client, the server, or the details and nature of the interactions between the client and the server. An intermediary deployed between clients and servers may establish an SSL VPN session between a client and a server. The intermediary may receiving a response from a server to a request of a client via the clientless SSL VPN session. The response may comprise one or more cookies. The intermediary may identify an access profile for the clientless SSL VPN session. The access profile may identify one or more policies for proxying cookies. The intermediary may determine, responsive to the one or more policies of the access profile, whether to proxy or bypass proxying for the client the one or more cookies.
摘要:
A system transfers data. The system includes an ingress node transferring data at a determined bandwidth. The ingress node includes a buffer and operates based on a monitored node parameter. The system includes a controller in communication with the ingress node. The controller is configured to allocate, based on the monitored node parameter, an amount of the determined bandwidth for directly transferring data to bypass the buffer of the ingress node.
摘要:
Example methods and apparatus for hierarchical bandwidth management are disclosed. An example method includes, receiving a data packet included in a first data traffic flow having a first rate of traffic. The example method further includes marking the data packet with a first marker type if the first rate of traffic is less than or equal to a first threshold, otherwise marking the data packet with a second marker type. The example method also includes combining the first data traffic flow with a second data traffic flow having a second rate of traffic to produce a third data traffic flow having a third rate of traffic. The example method still further includes, if the data packet is marked with the first marker type, forwarding the data packet in the third data flow. The example method yet further includes, if the data packet is marked with the second marker type and the third rate of traffic is less than or equal to a second threshold, forwarding the data packet in the third data flow, otherwise, discarding the packet.
摘要:
Methods, systems, and computer program product embodiments for managing traffic flows member of a plurality of available member resources in a communications device are disclosed. Embodiments include configuring a flow table containing a plurality of mappings, where each of the mappings specifies a relationship between one of a range of index values and at least one of the plurality of available member resources of an aggregated resource, assigning using the flow table respective traffic flows to at least one of the plurality of available links, and responsive to a change in the plurality of available member resources, changing the plurality of mappings.
摘要:
An apparatus may include a port interface that is arranged and configured to receive a packet from an ingress port, a traffic management module being operatively coupled to the port interface and that is arranged and configured to manage routing of the packet to a destination, and a packet processing engine that is arranged and configured to perform packet processing on the packet and to associate a tag with the packet, where the tag includes a packet processing source field, a destination field, and a fabric source field.
摘要:
A node comprising: an ingress port configured to receive data; a plurality of egress ports configured to transmit data; a routing table configured to provide, at least part of, both a preferred routing path and a recovery routing path; a data tag engine configured to read a tag, associated with the data, that indicates the routing state of the data and, based at least in part upon the tag determine whether to use the preferred routing path or the recovery routing path for a selected path, and determine if the tag is to be modified to indicate a change in the routing status of the data; and a routing engine configured to utilize the selected path to determine the egress port from which to transmit the data.
