Abstract: Systems and methods for assigning unique network identifiers in a packet-switched wired network and methods for communicating with a network device in a packet-switched wired network are provided. A request for a unique network identifier for a network device is received. A socket-based unique network identifier, including an IP address and one or more ports, is assigned to the network device. The unique network identifier is created by combining an IP address and one or more ports. This allows multiple unique network identifiers to be created from a single IP address, where each unique network identifier consists of the same IP address combined with a different group of one or more ports.

Abstract: Systems and methods for assigning unique network identifiers in a packet-switched wireless network and methods for communicating with a wireless device in a packet-switched wireless network are provided. A request for a unique network identifier for a wireless device is received. A socket-based unique network identifier, including an IP address and one or more ports, is assigned to the wireless device. The unique network identifier is created by combining an IP address and one or more ports. This allows multiple unique network identifiers to be created from a single IP address, where each unique network identifier consists of the same IP address combined with a different group of one or more ports.

Abstract: Methods and computer-readable media are provided to allow for the assignment of domain-name system (DNS) servers, static IP addresses, and dynamic home agents to a device requesting the establishment of an IPv6 data session. DNS servers may be determined for a particular device based on one or more device capabilities, such as the type of device or certain products or services to which the device is subscribed. The device capabilities are determined by querying a customer-profile database that defines certain information about users and devices, such as static IP addresses and device capabilities. The DNS servers are used by a device to translate a host name into a host address, in addition to establishing an IPv6 data session. Once determined, a component, such as an Authentication, Authorization, and Accounting (AAA) server may send the attributes to a packet-routing component, which assigns the DNS servers to the device.

Abstract: Computer systems, computer-readable media, and computerized methods for determining a media access (MAC) address that corresponds with a network identifier in a wireless or wired network are provided. A dynamic host configuration protocol (DHCP) server is employed to allocate a set of fractional IP addresses that include a common IPv4 address paired with a value of an IP version field, where none of the values overlap. When assigned to a client device, the fractional IP address uniquely identifies the client device within the network. A host device within the network is configured to broadcast an address resolution protocol (ARP) request to other devices within the network, such as the DHCP server, where the ARP request includes a fractional IP address associated with intended recipient(s) of communications from the host device. In response to the ARP request, the appropriate device or DHCP server returns a MAC address of the intended recipient(s).

Abstract: Communication to a target device using IP is provided. An IPv6 address is registered. An AAAA-record DNS lookup is performed and an A-record DNS lookup is performed, both using the IPv6 network. A response related to the AAAA-record DNS lookup is received and a response to the A-record DNS lookup is received. If a valid IPv6 address is contained in the AAAA-record response, communication uses IPv6. If no valid IPv6 address is contained in the AAAA-record response, an IPv4 address is registered and communication uses IPv4.

Abstract: Methods and computer-readable media are provided to enable an Internet protocol (IP) data session to be established between a mobile device and a telecommunications network. To establish an IP data session, it may be determined, prior to authenticating the device, whether the device is authorized to communicate via IPv4, IPv6, or both. A mobile device may be capable of communicating via both IPv4 and IPv6, such as a dual-stack device, but the device may only be authorized for either IPv4 or IPv6. A request to establish the IP data session may first be received from a mobile device, and an IP version with which the mobile device is authorized to communicate may then be determined by querying a customer-profile database. This authorization information may be communicated to an authentication component that authenticates the devices, and subsequently, an IP data session is initiated.

Abstract: Methods and computer-readable media are provided to monitor information corresponding to IP data sessions that are established using a single authentication session. A first IP data session may be established in a first IP version, such as IPv4 or IPv6, and a second IP data session may be established using a different IP version that was used in correlation to the first IP data session. Once the second IP data session is established, a message containing information corresponding to the second IP data session may be communicated to a receiving component, such as an AAA server. A similar message may be sent to the receiving component upon a termination of the second IP data session, such that the messages can be used to determine a value, such as a monetary value, associated with the second IP data session. A report may then be created that includes the determined value.

Abstract: Methods and computer-readable media are provided to allow for the establishment of an Internet protocol (IP) data session with a dual-stack mobile communications device by authenticating the device. An IP data session is requested, and a home agent sends an indication of this request. A DNS server that will be assigned to a device is identified by querying a database and is identified based on the device's capabilities. The device capabilities are determined by a device-capability identifier that is associated with the user of the device or the device itself, such as a network access identifier. The capabilities may include the device type, applications, programs, or services that the user of the device is subscribed to, or capabilities that are inherent to the phone. Once the DNS server is identified, a server identifier is sent to the home agent, which assigns the DNS server to the device.

Abstract: A network testing system for a device under test (DUT) uses a test tool to generate test packets provided to the DUT as source traffic and to receive the test packets back from the DUT as destination traffic. Before the test packets are returned from the DUT to the test tool, an external router receives the test packets from the DUT and forwards them back to the DUT. The DUT has a first pair of DUT interfaces coupled to the test tool and a second pair of DUT interfaces coupled to the external router. The DUT has a first virtual router with a first routing table configured to direct test packets received on one of the interfaces in the first pair of DUT interfaces to the external router. The DUT has a second virtual router with a second routing table configured to direct test packets received on one of the interfaces in the second pair of DUT interfaces to the test tool. Thus, test packets output by the test tool traverse the DUT more than once before returning to the test tool.
