7734748 Enhanced management opportunities to enable network element: A network element (NE) includes an intelligent interface (II) with its own operating environment rendering it active during the NE boot process, and with separate intelligence allowing it to take actions on the NE prior to, during, and after the boot process. The combination of independent operation and increased intelligence provides enhanced management opportunities to enable the NE to be controlled throughout the boot process and after completion of the boot process. For example, files may be uploaded to the NE before or during the boot process to restart the NE from a new software image. The II allows this downloading process to occur in parallel on multiple NEs from a centralized storage resource. Diagnostic checks may be run on the NE, and files, and MIB information, and other data may be transmitted from the II to enable a network manager to more effectively manage the NE.

7710871 Dynamic assignment of traffic classes to priority queue: An apparatus and method for dynamic assignment of classes of traffic to a priority queue. Bandwidth consumption by one or more types of packet traffic received in the packet forwarding device is monitored to determine whether the bandwidth consumption exceeds a threshold. If the bandwidth consumption exceeds the threshold, assignment of at least one type of packet traffic of the one or more types of packet traffic is changed from a queue having a first priority to a queue having a second priority.

7580349 Performing content-aware optical bandwidth allocation: Network resources allocated for particular application traffic are aware of the characteristics of L4+ content to be transmitted. One embodiment of the invention realizes network resource allocation in terms of three intelligent modules, gateway, provisioning and classification. A gateway module exerts network control functions in response to application requests for network resources. The network control functions include traffic path setup, bandwidth allocation and so on. Characteristics of the content are also specified in the received application network resource requests. Under request of the gateway module, a provisioning module allocates network resources such as bandwidth in optical networks and edge devices as well. An optical network resource allocation leads to a provisioning optical route. Under request of the gateway module, a classification module differentiates applications traffic according to content specifications, and thus creates and applies content-aware rule data for edge devices to forward content-specified traffic towards respective provisioning optical routes.

7359993 Interfacing external resources with a network element: External resources may be interfaced with a network element using an intelligent interface including an independent processing environment to enable the operational capabilities of the network element to be enhanced. The intelligent interface may serve as an interface to external resources such as network software repositories, storage servers, logging facilities and security services. By providing an intelligent interface, it is possible to interface external resources and enhanced services to the network element while allowing processing requirements to be offloaded to an external device or to the intelligent interface itself, so that the resources of the network element may be more fully utilized to perform network operations such as switching and routing functions. The intelligent interface also enables new resources to be made available to the network element when they are needed. An external communication port of the intelligent interface may be configured to operate using one of the USB standards.

It includes a network data transfer service, coupled to a network, that is capable of receiving XML encoded requests from a client also connected to the network. An XML engine is capable of understanding and parsing the XML encoded requests according to a corresponding DTD. The XML engine further instantiates a service using parameters provided in the XML encoded request and launches the service for execution on the network device. A set of device APIs interacts with hardware and software on the network device for executing the requested service on the network device. If necessary, a response is further collected from the device and provided to the client in a response message.

7237012 Classifying Java remote method invocation transport traffic: A data communication network for DiffServ communications includes a customized Java socket factory added to clients connected to a data communication network having a DiffServ-enabled edge router. When an application running on a client system wishes to make a remote procedure call to a remote server system on another network, it makes a call to an RMI stub which invokes an RMI transport layer having the custom socket factory to generate a socket used in the RMI call. The custom socket factory detects when a high priority RMI call is being made and can determine the identity of the calling procedure as well. The socket factory makes a side channel communication to the edge router to provide this information to the edge router, which then makes use of this data when performing DiffServ classification for packets transmitted during the course of the call.

7127526 Dynamically loading and managing software services on network: The present invention relates to an apparatus and method for dynamically loading and managing software services on a network device. A service environment ported to the network device includes a service environment kernel and a virtual machine. The service environment kernel continually operates on the network device and manages the downloading of services from a remote location onto the network device. In accordance with a request from a remote client such as a network manager, the service environment kernel causes instructions corresponding to the downloaded service to be provided to the virtual machine for execution on the network device. Associated with the service are service relationships. The service environment kernel manages these relationships by maintaining a registry of services and their dependencies on other services. The service environment kernel also controls the execution of services in accordance with the service relationships.

7047536 DiffServ classifying remote procedure call transport traffic: A data communication network for DiffServ communications has a software library added to clients connected to a data communication network having a DiffServ-enabled edge router. When an application running on a client system wishes to make a remote procedure call to a remote server system on another network, it makes its usual call for RPC invocation using the software library. This RPC call is intercepted by a protocol layer interposed between the application layer and the underlying RPC transport code. The protocol layer detects when an RPC call is being made and can determine the identity of the calling procedure as well. The library makes a side channel communication to the edge router to provide this information to the edge router or alternative service decider, which then makes use of this data when performing DiffServ classification for packets transmitted during the course of the call.
