摘要： A gateway network device may establish secure connections to a plurality of remote network devices using tunneling protocols to distribute to the remote network devices multimedia content received from one or more content providers. The consumption of the multimedia content may originally be restricted to local network associated with the gateway network device. The secure connections may be set up using L2TP protocol, and the L2TP tunneling connections may be secured using IPSec protocol. Use of multimedia content may be restricted based on DRM policies of the content provider. DRM policies may be implemented using DTCP protocol, which may restrict use of the multimedia content based on roundtrip times and/or IP subnetting. Each content provider may use one or more VLAN identifiers during communication of the multimedia content to the gateway network device, and the gateway network device may associate an additional VLAN identifier with each secure connection.
摘要翻译： 网关网络设备可以使用隧道协议建立到多个远程网络设备的安全连接，以向远程网络设备分发从一个或多个内容提供商接收的多媒体内容。 多媒体内容的消费原本可以限于与网关网络设备相关联的本地网络。 可以使用L2TP协议建立安全连接，并且可以使用IPSec协议来保护L2TP隧道连接。 可以基于内容提供商的DRM策略来限制多媒体内容的使用。 可以使用DTCP协议来实现DRM策略，其可以基于往返时间和/或IP子网划分来限制对多媒体内容的使用。 每个内容提供商可以在将多媒体内容通信到网关网络设备时使用一个或多个VLAN标识符，并且网关网络设备可以将附加VLAN标识符与每个安全连接相关联。

摘要： While transmitting a first Ethernet frame from the first buffer onto an Ethernet link, a first Ethernet device may stop transmitting the first frame prior to completing transmission of the frame. The first Ethernet device may then transmit a second frame from a second buffer onto the Ethernet link. The first Ethernet device may resume transmission of the first frame from the first buffer onto the Ethernet link. A second Ethernet device may receive, via the Ethernet link, a first portion of a first Ethernet frame and store the first portion of the first Ethernet frame in a first buffer. The second Ethernet device may then receive, via the Ethernet link, a second Ethernet frame and store the second Ethernet frame in a second buffer. The second Ethernet device may then receive, via the Ethernet link, a second portion of the first Ethernet frame and append it to the contents of the first buffer.
