  • Publication number: 20110106625
    Abstract: Location-based filtering and advertising enhancements for merged browsing of network content are described herein. In various embodiments, a client device may obtain its geographic location and provide that location to a server for filtering by the server of network content fragment suggestions based at least in part on the location. The client device may then receive some or all of the filtered suggestions for utilization in merged browsing. In some embodiments, a server may further receive an indicator of content being browsed. In response, the server may determine network content fragment suggestions, and may also determine an additional suggestion or prioritize a suggestion based an advertiser's interest. The server may then provide the suggestions and/or prioritization to the client device. In various embodiments, the server may also provide the advertisement(s) for display in a user interface of the client device along with the (prioritized) suggestions.

  • Patent number: 7895463
    Abstract: Redundant application network appliances using a low latency lossless interconnect link are described herein. According to one embodiment, in response to receiving at a first network element a packet of a network transaction from a client over a first network for accessing a server of a datacenter, a layer 2 network process is performed on the packet and a data stream is generated. The data stream is then replicated to a second network element via a layer 2 interconnect link to enable the second network element to perform higher layer processes on the data stream to obtain connection states of the network transaction. In response to a failure of the first network element, the second network element is configured to take over processes of the network transaction from the first network element using the obtained connection states without user interaction of the client. Other methods and apparatuses are also described.

  • Publication number: 20090288135
    Abstract: Techniques for building and managing network policies for accessing resources of a datacenter are described herein. In one embodiment, events are captured within a network element pertaining to certain activities of accessing certain resources of a datacenter, wherein the network element operates as an application service gateway to the datacenter. A new rule/policy is provisioned based on attributes extracted from the captured events, where the attributes includes at least one of user attribute, environment attribute, and a resource attribute. A simulation is performed on the new rule/policy under a real time network traffic condition, generating a simulation result. The new rule/policy is committed if the simulation result satisfies a predetermined condition, wherein the new rule/policy is enforced within the network element to determine whether a particular client is eligible to access a particular resource of the datacenter.
