The present disclosure discloses a method and network device for control plane protection for various tables using storm prevention entries. Specifically, the disclosed system receives a first packet, and creates an inactive entry in a table. The system then forwards the first packet from a first processor to a second processor for processing. Also, the system associates the inactive entry with a timestamp indicating when the first packet is forwarded to the second processor, and determines a configured interval (CI) associated with the table. Further, the system compares a difference between a current timestamp and the timestamp associated with the inactive entry against the CI upon receiving a second packet. If the difference is longer than the CI, the system associates the inactive entry with the current timestamp, and forwards the second packet to the second processor for processing. Otherwise, the system discards the second packet.

The present invention relates to a method, an apparatus and a system for a group session service in a software defined network, and relates to the field of the wireless communication and particularly to a group session service. By separating service control signaling from service data, the demands for a Push to talk over cellular (PoC) server is low and little change is made on a service flow, no extra demands for a user is needed, the control logic of the group call service is simplified, the load of the PoC server is reduced, and the delay of a multiple-party session is remarkably reduced, thereby effectively improving the QoE of the user.

In general, in one aspect, the disclosure describes a Universal Plug and Play (UPnP) Remote Access Server (RAS) to provide a communication channel between UPnP Remote Access Clients (RACs) connected thereto. The UPnP RAS maintains local discovery information for UPnP devices connected to a local network and remote discovery information for remote UPnP devices communicating therewith. The UPnP RAS provides the remote UPnP devices communicating therewith with the local discovery information and the remote discovery information. The remote discovery information is utilized by a first remote UPnP device to discover a second UPnP device and vice versa. After discovery, a first remote UPnP device can communicate with a second UPnP device and vice versa.

A method and system of relocating user equipment, such as a mobile device in a network from a first mobility anchor to a second mobility anchor, includes providing an identifier address to the user equipment when the latter is anchored to the first mobility anchor or gateway. When the user equipment is relocated to be anchored at the second mobility anchor or gateway, a per-host locator address is associated with the user equipment, the per-host locator address directing network packets to be routed to the second mobility anchor. A destination address of network packets addressed to the identifier address is translated to the per-host locator address, such that the network packets are routed to the second mobility anchor, and the destination address of network packets that are addressed to the per-host locator address are reverse translated to the identifier address, and the packets are forwarded to the user equipment.

Disclosed in the embodiments of the present invention is a data transmission method. The method comprises: simultaneously receiving data simultaneously transmitted by multiple transmitters, the data comprises multiple data frames simultaneously transmitted by at least one transmitter; generating a chunking acknowledgment message frame according to the receiving state of the data, the chunking acknowledgment message frame contains a group information identifier and data receiving state information, wherein the group information identifier is used to indicate multiple transmitters which belong to the same group pre-set correspondingly by the chunking acknowledgment message frame, and the data receiving state information is used to indicate the data receiving states of various transmitters which belong to the same group, the data receiving states comprise the receiving states of the multiple data frames simultaneously transmitted by at least one transmitter; and transmitting the chunking acknowledgment message frame to the multiple transmitters. By means of the present invention, the technical problems of being not beneficial to effective spectrum utilization and being not beneficial to power saving of user equipment which are caused by replying an ACK frame to the user equipment in order are solved, thereby improving the effective spectrum utilization.

A method for RDMA optimized high availability for in-memory storing of data includes receiving RDMA key-value store write requests in a network adapter of a primary computing server directed to writing data to an in-memory key-value store of the primary computing server and performing RDMA write operations of the data by the network adapter of the primary computing server responsive to the RDMA key-value store write requests. The method also includes replicating the RDMA key-value store write requests to a network adapter of a secondary computing server, by the network adapter of the primary computing server. Finally, the method includes providing address translation data for the in-memory key-value store of the primary computing server from the network adapter of the primary computing server to the network adapter of the secondary computing server.

A repeater receiving an original frame from a connected Electronic Control Unit (ECU) by a normal port divides data stored in a data area of the received frame, and each of a plurality of divided data pieces is stored in the data area in each of a plurality of division frames to be sent out to a destination. Each of the plurality of division frames of the original frame is distributed to one of two ring ports according to a determination of the repeater, and each of the division frames is sent out therefrom to the destination. In such manner, the frame transmission time required for a transmission of the frame is reduced.

Systems and methods for creating custom domain name links are provided. At least one server communicatively coupled to a network receives a request to create a custom domain name link to a third party service. The request identifies a custom domain name. The at least one server retrieves, from a third party service link database, an entry for the third party service specifying how to create the custom domain name link for the third party service and the at least one server creates the custom domain name link in accordance with the entry retrieved from the third party service link database.

System and method for supporting multiple concurrent SL to VL mappings in a high performance computing environment. In accordance with an embodiment, systems and methods can provide for two or more SL to VL mappings per ingress switch port in a network switched fabric. By allowing for multiple such mappings, greater virtual lane independence can be achieved while continuing to achieve quality of service guarantees.
