604 results about "Bulletin board" patented technology

A bulletin board (pinboard, pin board, noticeboard, or notice board in British English) is a surface intended for the posting of public messages, for example, to advertise items wanted or for sale, announce events, or provide information. Bulletin boards are often made of a material such as cork to facilitate addition and removal of messages, as well as a writing surface such as blackboard or whiteboard. A bulletin board which combines a pinboard (corkboard) and writing surface is known as a combination bulletin board. Bulletin boards can also be entirely in the digital domain and placed on computer networks so people can leave and erase messages for other people to read and see, as in a bulletin board system.

Method and system for processing virtual network messages based on virtual machine

The invention discloses a method and a system for processing virtual network messages based on a virtual machine. The method comprises that: when detecting that a virtual machine of a receiver is in a migration starting state, a data forwarding assembly of the receiver sends an application locking request to an information bulletin board; the information bulletin board locks records corresponding to the virtual machine of the receiver in a node information table of the information bulletin board according to the application locking request, and caches updating requests corresponding to the records; and the data forwarding assembly of the receiver judges the type of a received data message according to a local migration information table, and forwards and caches the data message according to the type of the data message. The system comprises an application locking module, a locking module, and a first data message forwarding and caching module. The method and the system ensure seamless switching of communication addresses in the migration process of the virtual machine, realize continuous and reliable operation of communication in a virtual network, and simultaneously improve information acquisition efficiency and forwarding efficiency of the data message.
