Disclosed are a client, a server, an RADIUS capability negotiation method and system, and the method includes: a client transmits to a server a first message carrying RADIUS capability parameters of the client; the server captures the RADIUS capability parameters in the first message, matches the RADIUS capability parameters in the first message with RADIUS capability parameters of the server to obtain a matching result, and transmits the matching result to the client through a second message; and the client determines whether to establish effective communication with the server according to the matching result in the second message. By means of the technical solutions of the disclosure, it is possible to extend the RADIUS protocol, and to solve the problem existing in the current RADIUS protocol that both sides in communication cannot perform RADIUS capability negotiation.

Client, server, radius capability negotiation method and system between client and server

Disclosed is a method for forwarding information in a distributed network, including that when receiving a message of an Application (APP) protocol, a forwarding device sends, according to a forwarding rule that is sent by a Software Defined Networking (SDN)/OpenFlow controller and corresponds to the APP protocol, the message to a corresponding application server directly or sends the message to a corresponding terminal directly. The disclosure further discloses a system for forwarding information in a distributed network. A transmission bandwidth of a control message between a network control layer and a forwarding layer can be ensured by means of the disclosure, thereby ensuring the stability of an SDN/OpenFlow message between the network control layer and the forwarding layer and ensuring system expansibility.

Method and system for forwarding information in distributed network

An announcement method, apparatus and system are provided. The method includes: an announcement node configuring sending ports of the announcement node in a first region and a second region, wherein, the first region and the second region apply different network protection switching technologies; the announcement node acquiring a protection switching request sent from the first region; and the announcement node sending the protection switching request to the second region through the sending port corresponding to the second region, wherein, a post-switching link state of the first region is contained in the protection switching request, and under a situation that the post-switching link state of the first region is inconsistent with a current link state of the second region, the second region needs to perform protection switching and otherwise does not need to perform the protection switching.

Announcement method, device and system

A transmission monitoring method and apparatus are provided. The method includes: in a case that an input port of a network node receives M frames, counting the number N of frames sent by an output port of the network node corresponding to the received M frames; in a case that the M is different from the N, determining that frame loss exists in the network node, wherein the M and the N are positive integers. Through the method and apparatus of the present document, the problems of failing to determine a specific device where the frame loss occurs and the construction cost being high are solved, the accuracy and the flexibility of monitoring a position of the frame loss are improved, and the construction cost is reduced.
