摘要： Techniques are provided to apply a network access control policy to a virtual machine (VM) migration before allowing the VM to migrate from one server to another server. At a first device in a network, a message is received from a second device, the message comprising information configured to request a migration of a virtual machine to the first device. A request is sent to the second device configured to request information about the operating conditions of the VM. A response to the request is received comprising information about the VM's operating conditions. A determination is made as to whether the information in the response complies with a network access control policy. In response to determining that the information complies with the network access control policy, the virtual machine is permitted to migrate, or otherwise the virtual machine migration request is denied.

摘要： In accordance with various embodiments, a Home Agent receives a registration request and sends a registration reply having a network mask extension including a network mask associated with the home address of the Mobile Node. Once the Mobile Node has obtained its network mask, it may send packets such as broadcast packets, as well as roam to its Home Agent. Additionally, in accordance with various embodiments, when a Home Agent receives a broadcast packet, it forwards the broadcast packet to a care-of address of the broadcast packet without duplicating the broadcast packet. Instead, the Foreign Agent obtains the subnet from the broadcast packet, identifies the Mobile Node(s) on that subnet, and duplicates the broadcast packet for transmission to the identified Mobile Node(s).

摘要： Systems and methods for adjusting audio levels in a plurality of audio signals are disclosed. One or more input signals containing one or more audio signals are depacketized. The audio signals are analyzed to determine if audio levels of the signals correspond to a desired audio level for at least some of the signals. The audio levels of signals that do not correspond are adjusted. Packets that do not require adjustment and the resulting adjusted packets are combined to form one or more output signals corresponding to the one or more input signals.

摘要： Methods and apparatuses for conserving addresses. The invention allows a mobile node to manage its own address, shifting responsibility away from the home agent. The home agent is able to detect when a mobile node has already been assigned an address for use of resources on the network. When the home agent recognizes that the mobile address has already been assigned an address, it allows the mobile node to use its already-assigned address in connection with mobile IP services. Additionally, the mobile node can be notified that it is now responsible for renewing the address.
摘要翻译：保存地址的方法和装置。本发明允许移动节点管理其自己的地址，使责任远离归属代理。归属代理能够检测何时移动节点已经被分配了用于在网络上使用资源的地址。当归属代理识别到移动地址已被分配地址时，它允许移动节点使用其已经分配的与移动IP服务有关的地址。另外，可以通知移动节点现在负责更新地址。

摘要： A method and system for identifying a network path between a source node and a destination node are disclosed. In one embodiment, the method includes generating a proxy trace message at the source node, transmitting the proxy trace message over the network path towards the destination node, and receiving the proxy trace message at the source node. The proxy trace message follows a path taken by application messages transmitted by the source node and the received proxy trace message includes addresses of the destination node and proxies in the network path.

摘要： Methods and apparatus for optimizing NAT traversal in Mobile IP are disclosed. Various mechanisms may performed independently or in combination with one another. A first mechanism enables one-way keep alive messaging to the Home Agent, while a second mechanism enables two-way keep alive messaging to the Home Agent, thereby enabling an entry in a NAT translation table to be maintained. The two-way keep alive messaging requires that the Home Agent send an acknowledgement message, while the one-way keep alive messaging does not. Keep alive messaging may be performed at the Mobile Node or the Foreign Agent. A third mechanism enables a Foreign Agent to encapsulate a registration request packet with the Foreign Agent care-of address in the source IP address field rather than an egress interface of the Foreign Agent. A fourth mechanism enables a Mobile Node to force a Home Agent to perform UDP tunneling.
摘要翻译：公开了用于优化移动IP中NAT穿越的方法和装置。各种机制可以独立地或彼此组合地执行。第一种机制使得能够向归属代理单向保持活动消息传递，而第二种机制允许向归属代理双向保持活动消息传递，从而使NAT转换表中的条目得以维护。双向保持活着消息传递要求家庭代理发送确认消息，而单向保持活动消息传递不需要。可以在移动节点或外部代理处执行活动消息传递。第三种机制使外部代理能够在源IP地址字段而不是外部代理的出口接口封装具有外部代理转交地址的注册请求分组。第四种机制使移动节点能够强制归属代理执行UDP隧道。

摘要： In accordance with one aspect of the invention, methods and apparatus for distributing a Mobile IP registration request to one of a plurality of Home Agents are disclosed. A registration request is received from a Foreign Agent to which the Mobile Node has roamed. One of the plurality of Home Agents is selected. The registration request is then forwarded to the selected one of the plurality of Home Agents. The source IP address of the registration request is an IP address of the Foreign Agent to which the Mobile Node has roamed, thereby enabling the selected one of the plurality of Home Agents to send a Mobile IP registration reply directly to the Foreign Agent without interception by the network device.
