Abstract: An electronic device includes an address generator module that generates a source address for each traffic class to be sent using a network interface. The source address includes a Unique Local Address (ULA) prefix and an interface identifier having a traffic class identifier as one or more most significant bits and a randomly generated remainder. The address generator module generates a destination address having the ULA prefix and the traffic class identifier. When a processor of the electronic device is selecting a source address for the traffic class according to rules of a network layer protocol (e.g., IPv6), including a rule that a longest matching address of possible source addresses to the given destination is selected as the source address, the generated source address is selected due to the one or more most significant bits of the interface identifier matching with the traffic class identifier of the destination address.

Abstract: An electronic device includes a port binding module that binds ports to processes. A process running on the electronic device sends a port request to the port binding module. The port binding module determines whether the requested port is a restricted port. If not, the port binding module binds the requested port to the process. If the requested port is restricted, then the port binding module determines whether the requesting process has an entitlement corresponding to the port. If the requesting process has the corresponding entitlement, then the port binding module binds the requested restricted port to the process. If not, then the port binding module denies binding the requested restricted port to the process.

Abstract: Techniques are disclosed relating to communicating, via IPv6-only networks, with devices on IPv4 networks. In some embodiments, a mobile device stores program instructions executable to: generate a request to access a network server that specifies an IPv4 literal, query a DNS server using a reserved name to determine an IPv6 prefix, synthesize an IPv6 address using the prefix and the IPv4 literal, create a transport layer connection to the network server using the synthesized IPv6 address, and transmit multiple packets using the connection, without re-translating the IPv4 literal for the packets. These per-connection translation techniques may reduce power consumption and/or processing time relative to per-packet translation, in some embodiments.

Abstract translation: 公开了关于通过仅IPv6网络与IPv4网络上的设备进行通信的技术。 在一些实施例中，移动设备存储可执行以执行以下操作的程序指令：生成访问指定IPv4文字的网络服务器的请求，使用保留名称查询DNS服务器以确定IPv6前缀，使用前缀合成IPv6地址， IPv4文字，使用合成的IPv6地址创建到网络服务器的传输层连接，并使用连接传输多个数据包，而不需要重新翻译数据包的IPv4文字。 在一些实施例中，这些每连接翻译技术可以减少相对于每个分组转换的功耗和/或处理时间。
