摘要： An electronic device (for example, a NIC card) can perform a base function (for example, “dumb” NIC functionality) and also has specialized hardware for performing an enhanced function (for example, TCP offload functionality). Initially, the electronic device is capable of performing the base function but the enhanced function is disabled. The electronic device is priced to be price competitive with other devices that perform the base function but not the enhanced function. By this pricing, large numbers of the electronic devices are disseminated into the marketplace. Once an electronic device has been disseminated and supplied to a user, the user can make an additional payment to have the enhanced function enabled. In one embodiment, a user who pays for the enhanced functionality accesses a web-based license manager and receives a license key. The license key is usable to write a capabilities code into the electronic device that enables the enhanced function.

摘要： In one embodiment, a system for communicating over a network is disclosed, the system comprising: a processor running a protocol processing stack to control a TCP connection; a first offload engine that receives control of the TCP connection from the stack to perform a first task corresponding to the TCP connection; and a second offload engine that receives control of the TCP connection from the first offload engine to perform a second task corresponding to the TCP connection. For example, the first offload engine can be protocol software such as an intermediate driver that can handle tasks such as teaming and/or reassembly of out-of-order data segments. As another example, the second offload engine can be a network interface card that provides hardware that accelerates data transfer.

摘要： The present invention is an address mapping gateway, used in an internetwork link, that associates all nodes in a domain with a single network number (referred to as a domain network address), and provides gateway-mapped node addresses that are unique within the domain. The address mapping gateway dynamically substitutes the "globally-unique" domain network address and the "domain-unique" gateway-mapped node address for a network number and node address, respectively, of a network layer address of a packet header received from a source node in the domain. Conversely, when a packet is received for a destination node in the domain, the address mapping gateway substitutes the originally-assigned network number and node address for the domain network address and gateway-mapped node address, respectively, prior to forwarding the packet to the node. Specifically, the address mapping gateway maintains an address mapping table that provides a cross-reference between (1) a source node address and the network number of the local network in which the node resides, and (2) a gateway-mapped node address generated by the address mapping gateway. Upon receipt of a packet from the source node, the address mapping gateway creates a mapping entry in the address mapping table that node and performs an address translation to a globally-unique network layer address. On the other hand, upon receipt of a packet destined for a destination node in the domain, the address mapping gateway locates the mapping entry for the packet's gateway-mapped node address and performs a reverse address translation to the originally-assigned network layer address.
摘要翻译：本发明是在互联网络链路中使用的地址映射网关，其将域中的所有节点与单个网络号码（称为域网络地址）相关联，并且提供在域内是唯一的网关映射节点地址。地址映射网关分别动态地将“全局唯一”域网络地址和“域唯一”网关映射节点地址替换为从源接收的分组报头的网络层地址的网络号和节点地址节点在域中。相反，当为域中的目的地节点接收到分组时，地址映射网关将分组的原始分配的网络号和节点地址分别替换为域网络地址和网关映射节点地址，然后将分组转发到节点。具体地说，地址映射网关维护地址映射表，其提供（1）源节点地址与节点驻留的本地网络的网络号之间的交叉引用，以及（2）生成的网关映射节点地址由地址映射网关。在从源节点接收到分组时，地址映射网关在地址映射表中创建一个映射条目，该节点并执行地址转换为全局唯一的网络层地址。另一方面，地址映射网关在接收到目的地为目的地节点的分组时，定位分组的网关映射节点地址的映射条目，并对原始分配的网络层地址进行反向地址转换。
