摘要： An email message delivery system is described that provides a fast and reliable managed email delivery service using MTAs and proxy servers. An email message is selected by an MTA for processing. The MTA determines a sender and an intended recipient associated with the email message. The MTA then identifies a pool of usable source internet protocol addresses for the email message based on the sender and selects a particular source IP address from the pool. The MTA then identifies a particular proxy server that is configured to handle the selected particular source IP address and communicates to the particular proxy server, information including the particular source IP address and the destination IP address. The MTA then transmits the email message to the destination IP address using a connection established by the proxy server between the particular source IP address and the destination IP address.

摘要： A multi-link device includes a first link queue, a second link queue, a control circuit, a first transmitter and a second transmitter. The control circuit includes a common queue for buffering a plurality of packets, each packet having a sequence number. The control circuit obtains a minimum sequence number of all packets in the first link queue and the second link queue, computes a maximum sequence number according to the minimum sequence number and a block acknowledgment window size, determines whether to allocate a set of packets from the common queue according to the maximum sequence number, and if so, allocates the set of packets to the first link queue and/or the second link queue. The first transmitter transmits a packet from the first link queue to a first receiving device, and the second transmitter transmits a packet from the second link queue to a second receiving device.

摘要： Systems and methods for virtual machine networking can include creating, by a hypervisor running on a host computer system, a first virtual machine (VM) using a first set of computing resources, where the first set of computing resources includes a portion of a second set of computing resources allocated to a second VM managed by the hypervisor. They can further include assigning a first vNIC (virtual Network Interface Controller) to the first VM and setting up a second vNIC to receive data packets transmitted by the first vNIC. Additionally, they can include associating the second vNIC with an identifier of the first VM and assigning the second vNIC to the second VM.

摘要： A network interface controller (NIC) capable of hybrid message matching is provided. The NIC can be equipped with a host interface, a hardware endpoint, and an endpoint management logic block. The host interface can couple the NIC to a host device. The hardware endpoint can facilitate a point of communication for an application running on the host device. The endpoint management logic block can maintain a list for storing a message associated with an endpoint represented by the hardware endpoint. The endpoint management logic block can then determine whether the utilization of the list is higher than a threshold. If the utilization is higher than the threshold, the endpoint management logic block can set a state of the endpoint to indicate that the endpoint is software managed. The NIC thus can transfer the control of the endpoint from the hardware endpoint to a software process of the host device.

摘要： A network interface device, an electronic device including same, and a method of operating same are provided. The network interface device is coupled to a host including a storage circuit. The network interface device includes a processing circuit and a packet receiving circuit which is used for receiving multiple network packets. The processing circuit performs the following steps: parsing the network packets to obtain multiple sequence numbers of the network packets; reordering the network packets based on the sequence numbers to generate reorder information; appending the reorder information to one of the network packets and generating packet order information, or generating the packet order information containing the reorder information; storing the packet order information in the storage circuit; and issuing an interrupt to the host. The packet receiving circuit or the processing circuit stores the network packets in the storage circuit before the processing circuit issues the interrupt.

摘要： The invention provides a method and system for scheduling a mobile edge computing-oriented distributed dedicated protection service. The method includes: dividing a service into subservices and generating corresponding protection subservices; and simultaneously selecting a working server for a subservice and selecting a MEC server for a protection subservice by using a double round-robin scheduling policy, where the server selected for the subservice is different from the server selected for the protection subservice. The system includes a large-scale network formed by MEC servers, where services and dedicated protection services corresponding to the services are arranged on the MEC servers by the above method. A total delay of a service is minimized on the premise of protecting the service, thereby avoiding a waste of computing resources or overloading, and implementing the division of mobile edge computing-oriented distributed services and the joint optimization of computing resources and protection computing resources of subservices.

摘要： Some embodiments provide an elastic architecture for providing a service in a computing system. To perform a service on the data messages, the service architecture uses a service node (SN) group that includes one primary service node (PSN) and zero or more secondary service nodes (SSNs). The service can be performed on a data message by either the PSN or one of the SSN. However, in addition to performing the service, the PSN also performs a load balancing operation that assesses the load on each service node (i.e., on the PSN or each SSN), and based on this assessment, has the data messages distributed to the service node(s) in its SN group. Based on the assessed load, the PSN in some embodiments also has one or more SSNs added to or removed from its SN group. To add or remove an SSN to or from the service node group, the PSN in some embodiments directs a set of controllers to add (e.g., instantiate or allocate) or remove the SSN to or from the SN group. Also, to assess the load on the service nodes, the PSN in some embodiments receives message load data from the controller set, which collects such data from each service node. In other embodiments, the PSN receives such load data directly from the SSNs.
