The present invention provides a method of selecting an optimal communication routing between a UE and a core network wherein a plurality of differing communication paths are establishable between the UE and the network. Duplicate packets are transmitted over two communication paths and a latency difference determined between the two paths. This latency difference is used to select a communication path for subsequent communication.

In general, in one aspect, the disclosure describes a Universal Plug and Play (UPnP) Remote Access Server (RAS) to provide a communication channel between UPnP Remote Access Clients (RACs) connected thereto. The UPnP RAS maintains local discovery information for UPnP devices connected to a local network and remote discovery information for remote UPnP devices communicating therewith. The UPnP RAS provides the remote UPnP devices communicating therewith with the local discovery information and the remote discovery information. The remote discovery information is utilized by a first remote UPnP device to discover a second UPnP device and vice versa. After discovery, a first remote UPnP device can communicate with a second UPnP device and vice versa.

A method for transmitting messages between a first networked device and a second networked device via a local network provided by a local network access point is disclosed. The method involves on the first networked device, determining whether the second networked device meets local communications criteria by determining at least one of whether the second networked device is accessible via the local network at a local network address, and whether the second networked device has registered for communications via local networks. The method also involves, in response to a determination that the second networked device meets the local communications criteria, transmitting the message via the local network access point to the local network address associated with the second networked device.

Top-of-rack (TOR) switches are connected to a network fabric of a data center. Each TOR switch corresponds to a rack of the data center, and is configured to provide access to the network fabric for computing devices mounted in the rack. In one method, a client device of a user is used to select various network service options. The service options correspond to services that can be provided to computing equipment of the user that is mounted in various racks of the data center. In response to receiving the selection of one or more service options, the network fabric of the data center is configured to connect the computing equipment to the selected services. In one approach, the network fabric is configured by creating and/or configuring one or more virtual networks to provide the connection to the services.

A switch receives a data packet containing training information. The switch learns a classifier based on the training information in the data packet, the classifier useable to classify data into at least one category.

Method and communication system for distributing information relating to a set of networks from a first node to a second node of the communication system, wherein a set of identifiers of respective networks which belong to the set of networks is stored at the first node. Hash values are generated at the first node for the identifiers in the set of identifiers using a hash function. The generated hash values are transmitted from the first node to the second node. The second node determines an identifier of a particular network which is available for communicating with the second node. The second node generates a hash value for the identifier of the particular network using the hash function. The second node then compares the hash value of the identifier of the particular network generated at the second node with the hash values received at the second node from the first node to thereby determine whether the particular network belongs to said set of networks.

Technology for characterizing internet application performance is described. An example method may involve, analyzing client requests from a plurality of internet service providers, the client requests comprising requests to access media items and being associated with internet service provider identities; identifying a set of the client requests that are associated with a first internet service provider; determining for at least one client request of the set: a request time, a payload data quantity, and an elapsed time; calculating a transfer rate comprising an application level throughput for the at least one client request, the transfer rate being based on the payload data quantity and the elapsed time; and calculating a performance measurement of the first and second internet service providers, the performance measurements being based on the transfer rate and on a portion of the set of client requests that have a transfer rate meeting a transfer threshold.

A two-tier Anycast addressing hierarchy enables deterministic traffic management in an Anycast system. Different locations of the Anycast system advertise a common Anycast cover route comprising a first-tier Anycast address with a first address prefix, and different specific routes comprising a set of second-tier Anycast addresses with a second address prefix, wherein each address of the set of second-tier Anycast addresses falls within the already advertised Anycast cover route, and wherein the second prefix is larger than the first prefix. Domain Name System (DNS) operation can resolve queries to the cover route when normal Anycast operation is desired or can be modified to resolve a subset of queries to a particular second-tier address in order to shift a deterministic amount of traffic based on the resolved subset of queries to a deterministically selected Anycast system location based on the location from which the particular second-tier address is advertised.
