    摘要： 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.

    摘要： 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. Other methods and apparatuses are also described.

    摘要： A data communication network (DCN) having a plurality of network devices coupled to the DCN with at least one of the network devices having a “boot once” connectivity manager processor (CMP). The CMP receives its power over the DCN rather than from the power applied to the network devices. The CMP can execute special operating system code and maintain network connectivity even if the network device itself is powered off, is being booted or is otherwise non-functional. The CMP is also coupled to the network device's memory so that it may respond to out-of-band polling requests for device status information from network management tools. With CMP, network administrators can monitor the boot process of network devices, determine that a network device is non-functional due to power loss and can maintain an accurate inventory status of spare network devices that are stored un-powered in a spares closet.

    摘要翻译： 具有耦合到DCN的多个网络设备的数据通信网络（DCN），其中至少一个网络设备具有“启动一次”连接管理器处理器（CMP）。 CMP通过DCN而不是从施加到网络设备的电源接收电力。 即使网络设备本身断电，正在引导或以其他方式不起作用，CMP也可以执行特殊的操作系统代码并维护网络连接。 CMP还耦合到网络设备的存储器，使得其可以响应来自网络管理工具的设备状态信息的带外轮询请求。 通过CMP，网络管理员可以监控网络设备的引导过程，确定网络设备由于电源损耗而无法正常工作，并且可以保持存储在备用壁橱中未供电的备用网络设备的准确库存状态。

    摘要： A network element having centralized TCP termination with multi-service chaining is described herein. According to one embodiment, a network element includes a switch fabric, a first service module coupled to the switch fabric, and a second and a third service modules coupled to the first service module over the switch fabric. In response to packets of a network transaction received from a client over a first network for access a server of a data center having multiple servers over a second network, the first service module is configured to terminate a TCP connection of the packets. The TCP terminated packets are transmitted to the second and third service modules over the switch fabric. The second and third service modules are configured to perform different application network services on the TCP terminated packets without having to perform a TCP process again. Other methods and apparatuses are also described.

    摘要： An application network appliance with virtualized services is described herein. According to one embodiment, a packet of a network transaction is received from a client for accessing an application server of a datacenter, where the network element operates as an application services gateway of the datacenter. A context associated with the application server is identified based on the packet, including information that identifies application services to be performed on the packet and resources to be allocated for performing the application services. A context includes information representing a logical instance of physical resources of the network element shared by multiple contexts. One or more application services are performed on the packet using the resources identified by the context. Other methods and apparatuses are also described.

    摘要： A highly scalable application layer service appliance is described herein. According to one embodiment, a network element includes a plurality of application service modules (ASMs), each providing one or more application services to network traffic, including layer 5-7 services, a lossless data transport fabric (LDTF), a network service module (NSM) coupled to each of the ASMs over the LDTF. In response to a packet of a network transaction received from a client over for accessing a server of a datacenter, the NSM is configured to perform layer 2-5 processes on the packet, generating a data stream. The NSM is configured to route the data stream to at least two ASMs over the LDTF to allow the ASMs to perform layer 5-7 services on the packet. Other methods and apparatuses are also described.

    摘要： A method and apparatus for providing quality of service parameters for transmissions of multicast streams on a cable network is provided. A cable network headend connects an external network to a hybrid fiber coax or cable network. The cable network headend maintains a table of cable modems with entries associating each cable modem with one or more quality of service parameters. Virtual cable modem entries are created for multicast streams when indications of quality of service for multicast streams are received by the cable network headend. Multicast packets arriving at the cable network headend are processed using the stored quality of service parameters for the corresponding multicast stream. The multicast packets may then be transmitted, queued, or dropped depending on the specified parameters and traffic shaping or policing algorithms.

    摘要： Method and devices are provided for allocating network resources in a flexible manner. In some implementations, a customer's unused resources for a particular type of service are assigned to another type of service. In other implementations, a first customer's unused resources are assigned to a second customer, e.g., in exchange for a relatively lower service charge to the first customer. The unused bandwidth may be assigned on a hierarchical or a non-hierarchical basis. In preferred embodiments, resources are allocated using a token bucket methodology. Preferably, high-priority resources are not compromised by the allocation scheme. The discipline or manner in which resources or bandwidth are shared may be specified in a static fashion or information regarding the state of congestion in the network maybe used to generate a dynamic (time varying) specification.
