20080219167 | Method, system and device for processing device overload in communication network - A method for processing device overload in a communication network includes: a device involved in a service connection checking in real time whether processing capability of the device exceeds an overload threshold set in the device, and sending to a neighboring device of the device an overload alarm message containing an address of the device if the processing capability of the device exceeds the overload threshold; the neighboring device restricting traffic passing through the device after receiving the overload alarm message. The method of the present invention enables the device involved in the service connection to automatically lead the establishment of the subsequent service connection reasonably, which improves the operation efficiency of network and shortens the processing delay of service connection. | 09-11-2008 |
20080240114 | Data Frame Forwarding Method By Data Relay Entity And Data Relay Entity - The present disclosure discloses a data frame forwarding method for forwarding a data frame via a data relay entity DRE applicable in an Ethernet, including: setting one or more ports of the DRE to be V-Switch enabled, and configuring one or more of the V-Switched DRE ports to operate in the V-Switch function and in an Ethernet function shared mode; configuring decision polices for forwarding a received data frame through the V-Switch function in the shared mode; when the data frame is received though the ports of the DRE configured in the shared mode, if flag information carried in the data frame matches the decision policies, forwarding the data frame through a forwarding process corresponding to the V-Switch function; otherwise forwarding the data frame through a forwarding process corresponding to an Ethernet function. | 10-02-2008 |
20090141729 | MULTIPLEX METHOD OF VLAN SWITCHING TUNNEL AND VLAN SWITCHING SYSTEM - A multiplex method of a virtual local area network (VLAN) switching (VS) tunnel includes the following steps. An ingress edge node of the VS tunnel maps a received customer data unit onto one virtual channel (VC) borne by the VS tunnel, and encapsulates the customer data unit into a VS tunnel Ethernet frame including a VS tag, a VC tag, and the customer data unit. The VC tag identifies the different VCs borne by the VS tunnel. An intermediate node of the VS tunnel switches the VS tunnel Ethernet frame according to the VS tag, and transports the customer data unit and the VC tag transparently in the VS tunnel. An egress edge node of the VS tunnel terminates the VS tunnel and the VC, recovers the customer data unit, and forwards the data according to the VC tag. | 06-04-2009 |
20100169280 | DISTRIBUTED NETWORK CONSTRUCTION AND STORAGE METHOD, APPARATUS AND SYSTEM - The disclosure relates to distributed network communications, and in particular, to a distributed network construction method and apparatus, a distributed data storage method and apparatus, and a distributed network system. When a node joins a distributed network, the ID of the node is determined according to the geographic location information about the node. Therefore, all the nodes in the same area belong to the same ID range, and the node IDs are allocated according to the area. Because the node IDs are determined according to the area, the local data may be stored in the node in the area according to the geographic information, inter-area data access is reduced. Therefore, the method, the apparatus, and the system provided herein reduce the data load on the backbone network, balance the data traffic and the bandwidth overhead of the entire network, and reduce the network instability. | 07-01-2010 |
20100268820 | USER DATA SERVER SYSTEM, METHOD AND APPARATUS - A user data server system includes: a data storage node, which stores user data, registers the user data in a Distributed Hash Table (DHT) network by using a key, and receives and processes user data operation requests; a DHT index node, which creates and maintains DHT routing information according to a DHT algorithm and stores information of data storage nodes where user data is stored according to the key and searches for information of a data storage node where target user data is stored according to the key; a DHT super maintenance node, which manages and optimizes the DHT network; and a front end node capable of protocol processing and service processing, which obtains a key associated with a target user and obtains information of a data storage node where the target user data is stored by querying the DHT index node via the DHT network according to the key, and performs operations on the user data stored in the data storage node where the target user data is stored. With the technical solution provided by the present invention, a user data server is not centralized and is highly scalable and highly reliable with a high cost-effectiveness. | 10-21-2010 |
20110305243 | METHOD AND DEVICE FOR IMPLEMENTING VIRTUAL-SWITCH - The present invention provides a method and a device for implementing a V-Switch. Through setting up a V-Switch correlation with respect to at least two VLAN tags, a DRE performs a V-Switch transmission on an Ethernet frame received according to the V-Switch correlation with respect to at least two VLAN tags. The invention can expand the number of V-Switch connections carried on a local link to 4096×4096, or even to 4096×4096×4096 . . . . Therefore, the problem of insufficient VLAN tag resources is solved, and the requirements for the scale of V-Switch technology is met. Moreover, a more effective V-Switch method is provided, the switching capability of V-Switch is improved, and the application scale of V-Switch technology is enlarged. | 12-15-2011 |
20130041982 | METHOD AND NODE FOR ACQUIRING CONTENT AND CONTENT NETWORK - The present invention discloses a method and node for acquiring content and a content network, and is related to the field of communications. The method includes: receiving a content request, where the content request at least includes an identifier of requested content; determining whether the content corresponding to the identifier can be acquired locally; if yes, acquired the content corresponding to the identifier locally; otherwise, searching, according to the identifier, a name resolution system for a target node that stores the identifier, and acquiring the content corresponding to the identifier from the target node; where the name resolution system comprises a multilevel DHT and a global content resolution structure, and the global content resolution structure supports name aggregation and longest matching search. | 02-14-2013 |
20150139166 | METHOD, DEVICE, AND SYSTEM FOR SUPPORTING CONTENT SUBSCRIPTION IN CONTENT NETWORK - A method is provided for content subscription in content network. As disclosed in the method, a content requesting node in the content network receives a first interest packet comprising a content identifier through a first port from a first user device, creates a subscription entry comprising the content identifier and an identifier of the first port, sends the first interest packet to the content providing node, receives a second interest packet through a second port from a second user device; adds an identifier of the second port to the subscription entry, receives multiple data packets provided by the content providing node according to the first interest packet, and sends the multiple data packets through the first port and the second port respectively to the first user device and the second user device according to the subscription entry. | 05-21-2015 |
