摘要： Systems and methods for stretching a subnet that do not require level 2 (L2) communications to be handled are provided. A user may gradually migrate VMs or applications instead of migrating an entire subnet at one time, may fail-over specific VMs without failing-over an entire subnet or renumbering IP addresses, may deploy applications to the cloud without the need to create a VPN, or may enable hybrid network connectivity without modifying routes or (re)configuring edge routers, among other benefits. The domains over which the subnet are stretched include a virtual gateway which is associated with the layer-3 (L3) addresses of the other domains. L3 communications within the domain are routed within that domain, and L3 communications within the subnet in another domain are intercepted by the local gateway, are passed to the remote gateway of the other domain, and are forwarded to the destination while leveraging L3 communications.

摘要： Methods, systems, and apparatuses are described for extending a network through the use of access nodes. The access nodes may receive packets from user devices via wireless networks. The packets may be routed to a remote server for further network access. The access nodes may communicate with the user devices using network addresses associated with the wireless networks.

摘要： Nameserver addresses are correlated in a multi-tier name server hierarchy comprising a first level authority for a domain, and one or more second level authorities to which the first level authority delegates with respect to a particular sub-domain associated with the domain. Preferably, the first level authority is IPv4-based and at least one second level authority is IPv6-based. The first level authority responds to a request issued by a client caching nameserver (a “CCNS”) and returns an answer that includes both IPv4 and IPv6 authorities for the domain. The CCNS is located at an IPv4 source address that is passed along to the first level authority with the CCNS request. The first level authority encodes the CCNS IPv4 source address in the IPv6 destination address of at least one IPv6 authority. Then, when the CCNS then makes a follow-on IPv6 request (with respect to the sub-domain) directed to the IPv6 authority, the IPv6 authority knows both the IPv6 address of the CCNS (as well as its IPv4 address. The IPv6 authority maintains the IPv4-IPv6 correlation. Over time, the IPv6 authority builds up a database of these CCNS IPv6-IPv4 associations.

摘要： Fully meshed virtual paths obtained with smaller number of settings, thus facilitating expansion of VPN service. A communication device in a virtual private network (VPN) having a VPN accommodation function for connecting an intra-organization network or inter-organization network through the Internet includes; a first means for generating a VPN address, a format of which includes both a VPN number for uniquely identifying a VPN in a certain scope and a closed address used in an organization or among organizations, either converting a packet header into a header having the above-mentioned VPN address or adding the above-mentioned VPN address to a packet header for transmission; and a second means for on receiving the packet having a header of the VPN address format, either converting the received packet into a packet format equivalent to an original packet format or removing a header having VPN address format.

摘要： A method of correlating nameserver addresses is implemented in a multi-tier name server hierarchy comprising a first level authority for a domain, and one or more second level authorities to which the first level authority delegates with respect to a particular sub-domain associated with the domain. Preferably, the first level authority is IPv4-based and at least one second level authority is IPv6-based. The first level authority responds to a request issued by a client caching nameserver (a “CCNS”) and returns an answer that includes both IPv4 and IPv6 authorities for the domain. The CCNS is located at an IPv4 source address that is passed along to the first level authority with the CCNS request. According to a feature of this disclosure, the first level authority encodes the CCNS IPv4 source address in the IPv6 destination address of at least one IPv6 authority. Then, when the CCNS then makes a follow-on IPv6 request (with respect to the sub-domain) directed to the IPv6 authority, the IPv6 authority knows both the IPv6 address of the CCNS (by virtue of having received it in association with the request) as well as its IPv4 address (by virtue of the encoding). The IPv6 authority maintains the IPv4-IPv6 correlation. Over time (i.e., as other CCNSs make requests), the IPv6 authority builds up a database of these CCNS IPv6-IPv4 associations.
摘要翻译：关联名称服务器地址的方法在包括域的第一级权限的多层名称服务器层级中实现，以及一个或多个第二级权限，第一级权限相对于与该属性相关联的特定子域域。优选地，第一级权限是基于IPv4的，并且至少一个第二级权限是基于IPv6的。第一级权限响应客户端缓存名称服务器（“CCNS”）发出的请求，并返回包含域的IPv4和IPv6权限的答案。 CCNS位于通过CCNS请求传递给第一级权限的IPv4源地址。根据本公开的特征，第一级权限对至少一个IPv6授权的IPv6目的地址中的CCNS IPv4源地址进行编码。然后，当CCNS然后对IPv6机构进行后续IPv6请求（相对于子域）时，IPv6授权机构知道CCNS的IPv6地址（凭借与请求）以及其IPv4地址（通过编码）。 IPv6权限维护IPv4-IPv6相关性。随着时间的推移（即像其他CCNS发出请求一样），IPv6授权机构建立了这些CCNS IPv6-IPv4关联的数据库。

摘要： An address translator includes an SIP message detecting function. Upon detection of an SIP message, the address translator sends the SIP message to an SIP address translator. The SIP address translator extracts addresses for translation, and makes a query to the address translator. The SIP address translator translates an IP address included in the SIP message, using translation information of the address translator. Thus, an SIP communication is accomplished between terminals belonging to different regions in association of the address translator and the SIP address translator.

摘要： Internet Protocol version 6 (IPv6) network device discovery techniques are disclosed. In some embodiments, IPv6 network device discovery includes determining a route entry (e.g., selecting a first route entry that is less than 126 bits and greater than 48 bits) of a route entry table of a seed device (e.g., a router, such as a well connected router); converting the route entry to an anycast address; and sending a probe to the anycast address. For example, using various techniques described herein, an Internet Control Messaging Protocol (ICMP) probe, for example, with incrementing hop count and the subnet-router anycast addresses as targets can be used to fully discover network devices on an IPv6 network.

摘要： A method of receiving a data packet from an IPv4 domain in an IPv6 domain, the data packet comprising an IPv4 destination address and a destination port number. The method comprises the following steps: constructing an IPv6 destination address by concatenating an operator prefix, the IPv4 destination address, and the destination port number; generating an IPv6 data packet from the IPv6 constructed destination address and the received IPv4 data packet; and routing the generated IPv6 data packet in the IPv6 domain using the IPv6 constructed destination address, the constructed address belonging to a range of IPv6 addresses routable to an interconnection equipment of the IPv6 domain with the IPv4 destination address.
