摘要： A configuration agent allows a network node seeking to be automatically configured with an IP address and a default gateway address to be configured as its own gateway. In first and second embodiments of the present invention, the configuration agent resides on a network device (such as a switch or bridge) that is coupled to two network segments, with one network segments including a node to be configured and another network segment including a server capable of automatically providing configuration parameters. In the first embodiment, the configuration agent acts as a snoopy agent. Messages from the configuration server to the node to be configured are "snooped" to discover messages containing an IP address and a default gateway address. Such messages are altered to copy the IP addresses offered to the nodes seeking configuration to the default gateway addresses, and the messages are sent on their way, thereby causing the node seeking to be configured to be its own default gateway. In the second embodiment of the invention, the configuration acts as a proxy agent. From the point of view of the node to be configured, the proxy agent appears to be a configuration agent. From the point of view of the configuration server, the proxy agent appears to be a relay agent if the configuration server and the node to be configured are on different subnets. When the configuration server sends messages to the node to be configured (possibly treating the proxy agent as a relay agent), the proxy agent intercepts the message and copies the offered IP address to the default gateway address in the message, thereby causing the node seeking to be configured to be configured as its own gateway. The proxy agent also substitutes its IP address for the IP address of the actual configuration server, thereby causing the node seeking to be configured to treat the proxy agent as the configuration agent.

摘要： A system implements checksumming of a network packet to be sent over a network. A processor constructs the network packet within a main memory. The network packet is transferred from the main memory to a packet storage memory within a network adapter. During the transfer, the network adapter calculates a checksum for the network packet. The network adapter then inserts the checksum into the network packet within the packet storage memory. The network adapter then sends the network packet to the network. In order to calculate the checksum for the network packet, hardware within the network adapter "snoops" an internal bus within the network adapter as the network packet is transported to the packet storage memory. Also, a checksum header is prepended to the network packet which includes control information for checksumming. This control information includes, for example, an indication whether the network adapter is to calculate a checksum and a specification of what data in the network packet is to be checksummed. The control information may additionally include a location within network packet where the checksum is to be inserted.

摘要： A networking packet is to be sent from a first virtual machine of a computing device to a second virtual machine of the computing device. A hardware network interface controller (NIC) of the computing device is to determine whether the networking packet is to be routed from the first virtual machine to the second virtual machine in accordance with a first approach or a second approach, based upon one or more considerations regarding a state of the computing device. The hardware NIC is then to control routing of the networking packet in accordance with the first approach or the second approach.

摘要： One embodiment disclosed relates to a method for remote mirroring of network traffic. A data packet to be remotely mirrored is received by an entry device. The entry device is pre-configured with a destination Internet Protocol (IP) address to which to mirror the data packet. An IP header is generated and added to IP encapsulate the data packet. The IP header includes the aforementioned destination IP address. The IP-encapsulated packet is forwarded to an exit device associated with the destination IP address. Subsequently, the exit device may decapsulate the IP-encapsulated packet to reproduce the original data packet.

摘要： One embodiment disclosed relates to a method for mirroring of select network traffic. A data packet is received by a network device. A determination is made as to whether a designated aspect of the packet matches a flagged entry in a look-up table on the network device. If a match is found, then copy of the packet is sent to an associated mirror destination. Another embodiment disclosed relates to a networking apparatus. The apparatus includes at least an operating system, a look-up table, and a mirroring engine. The operating system includes routines utilized to control the apparatus, and the look-up table includes selection information for mirror sources. The mirroring engine forwards copies of selected packets to a corresponding mirror destination. Another embodiment disclosed relates to a method of selecting packets to mirror that includes checking state information relating to the network traffic against dynamic mirroring criteria.

摘要： A method and apparatus are presented for an improved data transferring technique between a network and a computing system. A network adapter implements a data transfer from a network to the memory of a destination computing system, accumulating a checksum of all data transferred. The dedicated hardware allows data to be transferred through it and a checksum to be accumulated without intervention by the processor of the destination computing system. Software corrections can generate a checksum of the header data and then generate a net checksum by subtracting the header checksum from the gross checksum accumulated by the dedicated hardware, thus achieving the desired result with minimal intervention by the processor of the destination computing system.
