    摘要： A system includes an access node having an associated identifier. The access node is configured to insert the identifier into a network connection request. The system includes an IP edge service node connected to the access node and configured to receive the network connection request. The IP edge service node is further configured to store the inserted identifier and to insert the identifier into an Internet protocol version 6 (IPv6) address request transmitted according to dynamic host configuration protocol version 6 (DHCPv6) through an established network connection based on the network connection request. The system further includes a server configured to receive the IPv6 address request and assign an IPv6 address based on the IPv6 address request.

    摘要： Techniques for authenticating a user for access to an IP network include receiving from the user's host a DHCP request which includes user identifier data. A random challenge value is determined and sent to the user's host in a DHCP message format. A response message that includes a response value is received from the user's host in DHCP format. A verification value is determined based on a password value associated with the user identifier value in an AAA server and the current challenge value using a secure process that renders impractical an attempt to derive the password. If it is determined that the response value does not match the verification value, then a DHCP offer is prevented from being sent to the user's host in response to the DHCP request. Thus, a user is authenticated using DHCP instead of PPP.

    摘要翻译： 用于验证用户访问IP网络的技术包括从用户的主机接收包括用户标识符数据的DHCP请求。 确定随机挑战值，并以DHCP消息格式发送给用户的主机。 包含响应值的响应消息以DHCP格式从用户主机接收。 基于与AAA服务器中的用户标识符值相关联的密码值和使用不切实际的尝试导出密码的安全过程来确定当前挑战值的验证值。 如果确定响应值与验证值不匹配，则可以防止响应于DHCP请求向DHCP用户的主机发送DHCP报文。 因此，使用DHCP而不是PPP进行身份验证。

    摘要： Techniques for negotiating Point-to-Point Protocol (PPP) sessions over an Ethernet network include receiving configuration data that indicates a first node is connected to a second node thorough an Ethernet network that supports Ethernet frame payload sizes larger than 1500 octets. Request data is received at the first node from the second node. The request data indicates a request for PPP communications between the first node and the second node using a requested PPP payload size greater than 1492 octets. A particular PPP payload size greater than 1492 octets is determined. Response data is sent from the first node to the second node. The response data indicates that the particular PPP payload size greater than 1492 octets is to be used for PPP communications between the first node and the second node. These techniques allow better utilization of Ethernet Jumbo, Giant and Baby Giant frames.

    摘要： In one embodiment, a method includes establishing a control channel across a wide area network (WAN) from a first gateway that has a first public internetwork layer (L3) address to a second gateway that has a second public L3 address. Each gateway connects a local area network (LAN) to the WAN. Negotiations over the control channel establish a first set of private L3 addresses for the first LAN and a non-overlapping second set for the second LAN. A different address from the first set is provided for each different node in the first LAN. A discovery packet is received from the first LAN. The discovery packet is encapsulated in a tunnel packet directed to the second public L3 address. The tunnel packet is sent over the WAN to the second gateway which extracts the discovery packet. The second gateway sends the discovery packet over the second LAN.

    摘要： In one embodiment, a method includes receiving a data link layer packet, such as an Ethernet packet, at a local provider edge node in a provider network from a first customer edge node of multiple customer edge nodes connected directly to the local provider edge node. A tunnel data packet for a particular tunneling protocol is generated. The tunnel data packet includes tunnel data that indicates tunnel termination at a different provider edge in the provider network. The tunnel data packet also includes customer identifier data and the data link layer packet. The customer identifier data uniquely indicates a customer associated with the first customer edge node. The tunnel data packet is sent over the provider network.

    摘要： Techniques for supporting subscriber sessions for access to an IP network include receiving from a first node at a different second node, a Dynamic Host Configuration Protocol (DHCP) formatted echo-request message. The echo-request message includes a DHCP option field that holds data that indicates an echo-request type. In response to receiving the echo-request message, the second node sends to the first node a DHCP formatted echo-reply message that corresponds to the echo-request message. The echo-reply message includes a DHCP option field that holds data that indicates an echo-reply type. When received by the first node, the echo-response message causes the first node to determine a connected state with the second node. Point to Point Protocol (PPP) keep-alive messages between a customer premises node and a remote access server gateway to an IP network may be replaced by these DHCP echo-request and echo-reply messages.

    摘要翻译： 用于支持用户会话以访问IP网络的技术包括从不同的第二节点的第一节点接收动态主机配置协议（DHCP）格式的回送请求消息。 回应请求消息包括保存指示回显请求类型的数据的DHCP选项字段。 响应于接收到回波请求消息，第二节点向第一节点发送对应于回显请求消息的DHCP格式的回应应答消息。 回应应答消息包括保存指示回显应答类型的数据的DHCP选项字段。 当由第一节点接收时，回波响应消息使得第一节点确定与第二节点的连接状态。 客户端节点和到IP网络的远程访问服务器网关之间的点对点协议（PPP）保持活动消息可以被这些DHCP回显请求和回应回复消息所取代。
