摘要： A method of address allocation in a network comprises determining, from negotiations between nodes, whether a first node shall assume a server role responsible for distribution and management of network addresses to clients. If this determination is made, the first node is provided with a pool of network addresses. The invention provides a method of dynamic re-allocation of address pools between servers of the network, in accordance with, for example, network requirements or traffic load.

摘要： A domain name server includes a zone file containing partitioning rules that define the partitioning of all subfolders of this domain into subzones. The DNS data of each of these subzones is hosted by a partition server that is able to obtain from the zone file information for identifying the partition server able to respond to a query sent by a client to obtain a DNS folder.

摘要： A system and method for configuring client access to a network includes at a first port, accessing a first server on a first local area network associated with the first port. An authorized local area network other than the first local area network is determined to which an authorized connection can be properly made based on information in a client request. The first port is assigned to the authorized local area network. Communications are handled with a new client configuration in the authorized local area network.

摘要： A request for establishing an IP session from a mobile device to be activated and connected to a cellular network is redirected to a web portal or platform of the cellular network. When the mobile device sends an authentication request for requesting establishment of an IP session to the cellular network, the mobile device receives a restricted IP address from the cellular network if the mobile device is not currently authorized for communication via the cellular network. A reverse domain name system lookup is performed on the restricted IP address to find a host name of a web portal or platform of the cellular network corresponding to the restricted IP address. The mobile device determines whether or not redirection of an IP communication request to the web portal or platform of the cellular network is to occur based on the host name.

摘要： A computer subsystem is provided with a switch apparatus group that is at least one switch apparatus that is coupled to the communication network and a plurality of communication apparatuses that includes an internal management apparatus (an internal apparatus). The internal management apparatus transmits a request of a plurality of IP addresses that are allocated to the plurality of communication apparatuses to an external management apparatus that is disposed outside the computer subsystem. The external management apparatus manages whether or not each of M static IP addresses can be allocated, specifies a plurality of static IP addresses that can be allocated in response to the request, and transmits the plurality of specified static IP addresses to the internal management apparatus. The internal management apparatus allocates the plurality of static IP addresses to a plurality of internal apparatus.

摘要： A controller may help reduce network traffic that is associated with broadcasting of Dynamic Host Configuration Protocol (DHCP) packets by converting broadcast DHCP packets into unicast DHCP packets and forwarding the unicast DHCP packets to appropriate DHCP servers. The servers may be identified from a database of servers that is updated with DHCP server address information based on DHCP reply packets that are received by the controller from servers in the network. To convert DHCP request packets into unicast packets, the controller may modify address header fields of the packets such as Ethernet addresses and Internet Protocol (IP) addresses. The controller may forward the modified DHCP request packets to the server by providing packet forwarding rules such as flow table entries to the switches or by forwarding the modified DHCP request packets through the controller.

摘要翻译： 控制器可以通过将广播DHCP分组转换为单播DHCP分组并将单播DHCP分组转发到适当的DHCP服务器来帮助减少与广播动态主机配置协议（DHCP）分组相关联的网络流量。 服务器可以从基于DHCP控制器从网络中的服务器接收的DHCP应答分组的DHCP服务器地址信息更新的服务器的数据库中识别。 要将DHCP请求数据包转换为单播数据包，控制器可以修改数据包的地址头字段，例如以太网地址和Internet协议（IP）地址。 控制器可以通过向交换机提供流表条目等数据包转发规则，或者通过控制器转发修改的DHCP请求报文，将修改的DHCP请求报文转发给服务器。

摘要： An example method includes receiving an Internet protocol (IP) address request in a network and selecting an IP address associated with a prefix that represents an IP subnet. The prefix includes a color attribute to be provided as part of a communication session that includes a plurality of packets. The prefix defines one or more properties associated with an application for the session. The prefix is communicated to a network element in a signaling plane, the prefix is configured to be used to make a routing decision for at least some of the plurality of packets. In more specific embodiments, the method can include applying one or more network policies based on the prefix associated with the IP address. The method could also include decrypting an encryption protocol in order to identify the prefix of a subsequent communication flow, and executing a routing decision based on the prefix.
