A method for Internet content delivery in a content delivery network established at network locations, the content delivery network comprising a plurality of content servers for serving content resources. The plurality of content servers includes a plurality of subsets of content servers, each subject being located at one of a plurality of Internet data centers. For each Internet Protocol (IP) address block from which requests for content resources are expected to be received, the method generates a candidate list of Internet data centers to be used to service the requests for content resources. For the IP address block, the method selects at least one of the Internet data centers from the candidate list to be used to service the requests for content resources. The selected Internet data center for the IP address block is written into a network map. The selecting step is carried out concurrently for each IP address block from which requests for content resources are expected to be received such that the network map comprises the selected Internet data center for each IP address block. The network map is then provided to a domain name service (DNS) associated with the content delivery network. In response to a DNS query received at the domain name service associated with the content delivery network, the network map is used to identify one of the Internet data centers from the candidate list to be used to service a request for a content resource.

A meshing network comprising one full function controller (WDC) and a plurality of nodes (WDN, WSN), that is RF quiet capable with very low power consumption and the ability to quickly heal itself and create new network paths. The network uses an addressing scheme that allows for each node to not have a network map but still be able to route messages. A piping scheme allows a mesh to become a high throughput network. A sensor rail protocol definition allows sensor devices to connect to nodes and route messages through the network.

A client player performs a query to a nameserver against a network map of Internet traffic conditions. The query is made asking for a particular service (e.g., RTSP) via a particular protocol (TCP) in a particular domain. In response, the nameserver returns a set of one or more tokens, with each token defining a machine or, in the preferred embodiment, a group of machines, from which the player should seek to obtain the stream. The player may then optionally perform one or more tests to determine which of a set of servers provides a best quality of service for the stream. That server is then used to retrieve the stream. Periodically, the client player code repeats the query during stream playback to determine whether there is a better source for the stream. If a better source exists, the player performs a switch to the better stream source “on the fly” if appropriate to maintain and / or enhance the quality of service. Preferably, the client player publishes data identifying why it selected a particular server, and such data may be used to augment the network map used for subsequent request routing determinations.

A policy component comprises policy configuration information. The policy configuration information contains one or more rules. Each rule and group of rules can be associated with a set of response actions. As the nodes on the monitored networks change or intrusive actions are introduced on the networks, network change events or intrusion events are generated. The policy component correlates network change events and / or intrusions events with network map information. The network map contains information on the network topology, services and network devices, amongst other things. When certain criteria is satisfied based on the correlation, a policy violation event may be issued by the system resulting in alerts or remediations.

An intelligent traffic redirection system performs global load balancing for Web sites located at mirrored data centers. The system relies on a network map that is generated continuously, preferably for the user-base of the entire Internet. Instead of probing each local name server (or other host) that is connectable to the mirrored data centers, the network map identifies connectivity with respect to a much smaller set of proxy points, called “core” (or “common”) points. A core point is representative of a set of local name servers (or other hosts) that, from a data center's perspective, share the point. To discover a core point, an incremental trace route is executed from each of the set of mirrored data centers to a local name server that may be used by client to resolve a request for a replica stored at the data centers. An intersection of the trace routes at a common routing point is then identified. Thus, for example, the common routing point may be the first common point for the trace routes when viewed from the perspective of the data centers (or the last common point for the trace routes when viewed from the perspective of the local name server). The common routing point is then identified as the core point for the local name server.

The architecture is desirably implemented in a proton beam therapy system to provide flexible security policies which improve patent safety and facilitate system maintenance and development.

A trace detector prevents network mapping and tracing by detecting an initial packet containing an initial time to live value that meets a first predetermined threshold range. The trace detector identifies a source address of the initial packet and adjusts a threshold time to live range for detection of at least one subsequent trace route or response packet associated with the source address of the initial packet. In response to detecting the subsequent packet(s), the trace detector processes the subsequent packet(s) associated with the source address of the initial packet according to a security policy to prevent a trace process originating the initial packet from tracing a network using the at least one subsequent packet.

The failover of nodes within networks, using a multicast address or a multicast port, is disclosed. A first node of a network joins a multicast group having a multicast address, which is assigned to the first node. Communication to the first node is achieved via communication to the multicast address, and / or through a multicast port on a switch of the network mapping to a port on the first node. When the first node fails, one of two actions occurs. First, a second node of the network may join the multicast group, such that the multicast address is assigned to the second node, and the second node handles communication to the multicast address. Second, the multicast port on the switch may be remapped to a port on the second node, so that communication to the multicast address is directed to the port on the second node.

The invention discloses a method for mapping a mobile virtual network based on clustering. The method for mapping the mobile virtual network based on the clustering aims to improve the mapping success rate from a virtual network to a mobile physical network and virtual network revenue and to reduce mapping overhead.
