Definitions
- At least some embodiments disclosed herein relate to data storage, and more particularly, to geolocation assisted data forwarding storage.
- the volume of data that must be stored by individuals, organizations, businesses and government is growing every year. In addition to just keeping up with demand, organizations face other storage challenges. With the move to on-line, real-time business and government, critical data must be protected from loss or inaccessibility due to software or hardware failure.
- many storage solutions on the market today offer protection against some failure modes, such as processor failure, but not against others, such as disk drive failure. Many organizations are exposed to the risk of data loss or data unavailability due to component failure in their data storage system.
- DAS Direct Attached Storage
- Network Storage includes disks connected directly to a server.
- Network Storage includes disks that are attached to a network rather than a specific server and can then be accessed and shared by other devices and applications on that network.
- Network Storage is typically divided into two segments, i.e., Storage Area Networks (SANs) and Network Attached Storage (NAS).
- SANs Storage Area Networks
- NAS Network Attached Storage
- a SAN is a high-speed special-purpose network (or subnetwork) that interconnects different kinds of data storage devices with associated data servers on behalf of a larger network of users.
- a SAN is part of the overall network of computing resources for an enterprise.
- a storage area network is usually clustered in close proximity to other computing resources but may also extend to remote locations for backup and archival storage, using wide area (WAN) network carrier technologies.
- WAN wide area
- NAS is hard disk storage that is set up with its own network address rather than being attached to the local computer that is serving applications to a network's workstation users. By removing storage access and its management from the local server, both application programming and files can be served faster because they are not competing for the same processor resources.
- the NAS is attached to a local area network (typically, an Ethernet network) and assigned an IP address. File requests are mapped by the main server to the NAS file server.
- the present invention provides methods and apparatus, including computer program products, for geolocation assisted data forwarding storage.
- the invention features, a method including, in a network of interconnected computer system nodes, receiving a request from a source system to store data, directing the data to a computer memory in conjunction with its geolocation, geolocation enabling selecting nodes that are proximate to each other or a user to increase speed and efficiency, and continuously forwarding the data from one computer memory to another computer memory in the network of interconnected computer system nodes in conjunction with their geolocations without storing on any physical storage device in the network, geolocation enabling selecting nodes that are proximate to each other or the user to increase speed and efficiency.
- the invention features a network including a group of interconnected computer system nodes each receiving data and continuously forwarding the data from computer memory to computer memory in conjunction with IP address geolocations without storing on any physical storage device in response to a request to store data from a requesting system and retrieve data being continuously forwarded from computer memory to computer memory in response to a request to retrieve data from the requesting system, each node further configured to detect the presence of data in its memory, apply a time stamp, and forward the data to computer memory of another node in the interconnected computer systems nodes according to a node's availability and geolocation, geolocation enabling selecting nodes that are proximate to each other or a user to increase speed and efficiency.
- FIG. 1 is a block diagram of an exemplary network.
- FIG. 2 is a block diagram of an exemplary user system.
- FIG. 3 is a block diagram of an exemplary network system.
- FIG. 4 is a flow diagram of a process.
- FIG. 5 is a flow diagram of a process.
- the present invention is a continuous data forwarding system, i.e., data is stored by continually forwarding it from one node memory to another node memory.
- an exemplary network 10 includes a user system 12 and a number of network systems 14, 16, 18, 20, 22.
- Each of the network systems 14, 16, 18, 20, 22 can be considered to be a node in the network 10 and one such network system may be designated as a central server, such as network system 14, which may assume a control position in network 10.
- Each of the nodes 14, 16, 18, 20, 22 may be established as a privately controlled network of peers under direct control of the central server 14.
- Peered nodes may also be a mix of private and public nodes, and thus not under the direct physical control of the central server 14.
- the network 10 may also be wholly public where the central server 14 (or servers) has no direct ownership or direct physical control of any of the peered nodes.
- the user system 12 can include a processor 30, memory 32 and input/output (I/O) device 34.
- Memory 32 can include an operating system (OS) 36, such as Linux, Apple® OS or Windows®, one or more application processes 38, and a storage process 100, explained in detail below.
- Application processes 38 can include user productivity software, such as OpenOffice or Microsoft® Office.
- the I/O device 34 can include a graphical user interface (GUI) 40 for display to a user 42.
- GUI graphical user interface
- each of the network systems, such as network system 14, can include a processor 50 and memory 52.
- Memory 52 can include an OS 54, such as Linux, Apple® OS or Windows®, and a data forwarding process 200, explained in detail below.
- the present invention does not use fixed physical data storage to store data.
- data is directed to a node in the network 10, assisted by a geolocation of the node, where it is then continuously forwarded from node memory to node memory in the network 10 by the data forwarding process 200 in each of the network nodes without storing on any physical storage medium such as a disk drive.
- the forwarded data resides only for a very brief period of time in the memory of any one node in the network 10.
- Data is not stored on any physical storage medium in any network node.
- Using geolocation enables speed and efficiency in forwarding data throughout the network, i.e., by selecting nodes that are proximate to each other and/or the user.
- Geolocation generally refers to identifying a real-world geographic location of an Internet connected computer, mobile device, website visitor or other. Geolocation can be used to refer to the practice of assessing the location, or it can be used to refer to the actual assessed location or location data. Geolocation can be performed by associating a geographic location with, for example, the Internet Protocol address, Media Access Control (MAC) address, Radio Frequency Identification (RFID), hardware embedded article/production number, embedded software number (such as UUID, Exif/IPTC/XMP or modern steganography), Wi-Fi connection location, or device GPS coordinates, or other, perhaps self-disclosed, information.
- MAC Media Access Control
- RFID Radio Frequency Identification
- hardware embedded article/production number such as UUID, Exif/IPTC/XMP or modern steganography
- Wi-Fi connection location or device GPS coordinates, or other, perhaps self-disclosed, information.
- Geolocation by IP address is the technique of determining a user's geographic latitude, longitude and, by inference, city, region and nation by comparing the user's public Internet IP address with known locations of other electronically neighboring servers and routers.
- GPS Global Positioning System
- NetGeo This system was a publicly accessible database of geographically located IP addresses. Through the use of many complex rules, the NetGeo database slowly filled and was corrected for the location of IP addresses.
- the NetGeo response includes the city, state, country, latitude and longitude of the IP address in question. Furthermore, the granularity (LAT_LONG_GRAN) also is estimated to give some idea about the accuracy of the location. This accuracy also can be deduced from the LAST UPDATED field. Obviously, the older the update, the more likely it is that the location has changed. This is true especially for IP addresses assigned to residential customers, as companies holding these addresses are in constant flux. [0035] Several existing packages assist in retrieving information from the NetGeo database.
- the PEAR system has a PHP package, and a PERL module, CAIDA: :NetGeo:: Client, is available. It is a relatively straightforward task to make a request in whatever language you are using for your application or service. For example, a function in PHP for getting and parsing the NetGeo response looks like this:
- preg_match ("/LAT:(.*)/i", SNetGeoHTML, Stemp) or die("Could not find element LAT”);
- preg_match ("/LONG:(.*)/i", SNetGeoHTML, Stemp) or die("Could not find element LONG");
- RFC 1876 is the standard that outlines "A Means for Expressing Location Information in the Domain Name System.”
- this is done by placing the location information of a server on the DNS registration page.
- Several popular servers have employed this standard but not enough to be directly useful as of yet.
- host is a DNS lookup utility that allows users to find out various pieces of information about a host.
- the simplest use is doing hostname to IP address lookups and the reverse.
- the reverse, dotted-decimal IPv4 notation, is used for this, and the actual server that hosts the canonical name is returned.
- the type flag, -t can be used to obtain specific information from the host record from the name server.
- Service providers typically provide an internal naming scheme for assigning IP addresses and associating names with these addresses.
- the canonical name of an IP address contains the country-code top-level domain (ccTLDs) in a suffix. CN is China, FR is France, RO is Bulgaria and so on.
- the name even may contain the city or region in which the IP address is located. Often, however, this information is shortened to some name that requires a heuristic to determine. For example, in your service or application, a user may appear to be coming from dl4-69-l- 64.try.wideopenwest.com. A whois at this address reveals it is a WideOpenWest account from Michigan.
- Information such as that presented on the GNS also can be used to provide users with utilities and services specific to their geographical locations. For example, it is possible to determine a user's local currency, time zone and language. Time zone is especially useful for members of a community or chat group to determine when another friend may be available and on-line.
- storage process 100 includes sending (102) a request to a central server 14 to store or retrieve data. If the request is a retrieve data request, storage process 100 receives the requested data from the central server 14 or node in the network.
- storage process 100 receives (104) an address of a node from the central server 14 and forwards (106) the data to the node memory represented by the received address.
- the central server 14 is assisted in finding an appropriate address by a geolocation, which can help locate a node that is underutilized or light in terms of network traffic.
- data forwarding process 200 includes receiving (202) a request to store or retrieve data. If the received request is a request to store data, data forwarding process 200 determines (204) an address of a node available to receive the data in memory assisted by its geolocation. This determination (204) can include using a geolocation to help locate a node, pinging the network and determining which of the nodes in a network is available, or determining which node in the network has the least traffic, or determining which node in the network has the largest available memory, or the geographic coordinates of the node, or any combination of these or other factors. Using geolocation enables greater speed and efficiency by selecting nodes that are proximate to each other and/or the user.
- Process 200 sends (206) a message to the user system with the address of a specific node for the requester to forward the data.
- Process 200 detects (208) the presence of data in node memory.
- Process 200 forwards (210) the data in memory to another node in the network of nodes, assisted by geolocation (e.g., a location of the node in the network) and continues to repeat detecting (208) and forwarding (210) of the data from node memory to node memory assisted by geolocation.
- process 200 affixes (212) a time stamp to the data.
- Forwarding can include pinging the node in the network to determine which of the nodes in the network is available, or determining which node in the network has the least traffic, or determining which node in the network has the largest available memory, or any combination of these or other factors.
- data undergoes an encrypted "handshake" with the node or central server 14 or user.
- This can be a public or private encryption system, such as the Cashmere system, which can use public -private keys.
- Cashmere decouples the encrypted forwarding path and message payload, which improves the performance as the source only needs to perform a single public key encryption on each message that uses the destination's unique public key. This has the benefit that only the true destination node will be able to decrypt the message payload and not every node in the corresponding relay group.
- Cashmere provides the capability that the destination can send anonymous reply messages without knowing the source's identity.
- data forwarding process 200 matches (214) at the central server 14 using a hash mark or other unique code that can be "sniffed" by the node upon the data entering the node via the encryption handshake. This can occur by pinging the nodes in the network.
- Process 200 sends (216) the message to return the data to the user directly to the node or node state where the central server 14 believes the data will likely appear.
- process 200 forwards (218) in node memory the data to the requester and forwards (220) a confirmation message that the data has been sent to the user.
- This routing message may be sent directly to the central server 14 or may be passed to the central server 14 or servers via other node(s) or supernode(s) in the network 10.
- the network 10 creates data storage without caching, downloading and/or storing the data on any physical storage medium. Data storage and management is accomplished via a continuous routing of the data from node memory to node memory, the forwarded data only downloaded when the user requests the data to be returned to the user from the network 10.
- New nodes and node states may be added and/or deleted from the network 10 based upon performance. Users may have access to all nodes or may be segmented to certain nodes or "node states" by the central server(s) or via the specific architecture of the private, public or private-public network.
- Individual nodes, nodes states and supernodes may also be extranet peers, wireless network peers, satellite peered nodes, Wi-Fi peered nodes, broadband networks, and so forth, in public or private networks.
- Peered nodes or users may be used as routing participants in the network 10 from any valid peer point with the same security systems employed, as well as custom solutions suitable for the rigors of specific deployments, such as wireless encryption schemes for wireless peers, and so forth.
- process 200 rather than have data cached or held in remote servers, hard drives or other fixed storage medium, the data are passed, routed, forwarded from node memory to node memory. The data are never downloaded until the authorized user calls for the data. A user on the system may authorize more than one user to have access to the data.
- a primary goal in process 200 is to generate a data storage and management system where the data is never fixed in physical storage, but in fact, is continually being routed/forwarded from node memory to node memory in the network.
- the path of the nodes to which data is forwarded may also be altered by the central server 14 to adjust for system capacities and to eliminate redundant paths of data that may weaken the security of the network due to the increased probability of data path without this feature.
- the invention can be implemented to realize one or more of the following advantages.
- a network creates data storage without caching or downloads. Data storage and management are accomplished via a constant routing of the data.
- Embodiments of the invention can be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations of them.
- Embodiments of the invention can be implemented as a computer program product, i.e., a computer program tangibly embodied in an information carrier, e.g., in a machine readable storage device or in a propagated signal, for execution by, or to control the operation of, data processing apparatus, e.g., a programmable processor, a computer, or multiple computers.
- a computer program can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment.
- a computer program can be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network.
- Method steps of embodiments of the invention can be performed by one or more programmable processors executing a computer program to perform functions of the invention by operating on input data and generating output. Method steps can also be performed by, and apparatus of the invention can be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).
