摘要:
In a multi-core platform in which secondary processing cores do not have direct WAN connectivity, methods and apparatus are described that enable the secondary processing cores to provide DNS resolution services to their network applications and/or client devices attached thereto. In an exemplary embodiment, a primary processing core having direct WAN connectivity and a DHCP client includes a DNS proxy service module which acts as a DNS server to the platform's secondary processing cores. Each secondary processing core sends DNS queries to the primary core DNS proxy service module. A primary core DNS resolver regenerates DNS queries based on the DNS queries from the secondary cores and forwards them for resolution to WAN-side DNS servers whose IP addresses were provided to the DHCP client in response to an IP lease request. The resolved IP addresses are returned by the WAN-side DNS servers to the primary processing core, which provides them to the requesting secondary core applications or client devices, via the DNS proxy service module.

The invention relates to a method for configuring a device in a local area network using a gateway. The gateway is being communicatively coupled to a remote management server outside the local area network. The local area network comprises a protected portion and an unprotected portion. The method comprises the following actions: First a connection request is received from a user device. The user device is provided with an address that enables the user device to establish a connection with the gateway within the unprotected portion of the local area network. Then a configuration request is received from the user device, in which the configuration request includes device information. Network information is appended to the configuration request and the appended configuration request is sent to the remote management server. In response a configuration response message is received. The response message includes the configuration data from the remote management server. Finally, configuration of the user device is established within the protected portion of the local area network using the configuration data.

A method of address allocation in a network comprises determining, from negotiations between nodes, whether a first node shall assume a server role responsible for distribution and management of network addresses to clients. If this determination is made, the first node is provided with a pool of network addresses. The invention provides a method of dynamic re-allocation of address pools between servers of the network, in accordance with, for example, network requirements or traffic load.

A hosted network management solution for communications over a computer network supports data communication across a network in accordance with a network message protocol such that communications are established between a network host and a node device. The and the node device performs a self-configuring operation in which the network host identifies a network owner associated with the hosted network, and maintains a persistent network connection path between the network host and the node device for the exchange of network packet messages. The network host retrieves message data from the network packet messages it receives from the node device and performs network management operations to provide a user management interface to the identified network owner. The hosted network management enables more convenient setup and configuration for the network owner and provides more complete and effective network management tools.

An apparatus receives and analyzes a packet transmitted via a network, and performs network setting according to data included in the packet. Further, if it is determined that the received packet is a packet addressed to the apparatus and is not a setting packet for the network setting, the apparatus is controlled not to analyze the packet.

A method of managing IP addresses in a device performing communication using the IP address includes acquiring IP addresses by a plurality of methods; storing the plurality of IP addresses such that the methods are discernable when the plurality of acquired IP addresses are the same, determining an effective IP address used in the communication from the plurality of IP addresses according to predetermined priority in the methods, and setting the IP address to be used in the communication; and determining the valid IP address according to the priority from the stored IP addresses except for the disappearing IP address when the set IP address disappears, and setting the IP address to be used in the communication.

An approach is provided for providing acknowledgement signaling. A transmission failure associated with data from a user equipment is determined. An allocation message is generated for signaling of the transmission failure to the user equipment. The allocation message provides allocation of resource for retransmission of the data.

Attribute values in a customized logical group definition are displayed to a user, each customized logical group definition being associated with a network that includes multiple network entities, and each of the multiple network entities having one or more associated attribute values. A user selection of one of the different attribute values is received, and a determination is made of one or more of the multiple network entities that have an associated attribute value that matches the user selected attribute value. Identifiers of each of the one or more network entities that have an associated attribute value that matches the user selected attribute value are displayed.
摘要:
A device schedules a scan of a group of devices associated with an application network/system, and receives, at a scheduled time, scan information from the group of devices, where the scan information is provided in different formats. The device also converts the scan information, in the different formats, into a single normalized format, and processes the normalized scan information to produce enriched, normalized scan information.
摘要:
A computer implemented method, and computer program product for requesting resources. The computer receives an assignment of an Internet protocol address. The computer compares a computer context of a client computer with an intranet access criterion to form a comparison result. The computer selects at least one preferred uniform resource identifier based on the comparison result, indicating the intranet is accessible. The computer transmits a request to a server using at least one preferred uniform resource identifier using a packet network.
