The invention relates to technology of network communication, in particular to a method for realizing an IP telecommunication network based on a tunnel. Aiming at the defects in the prior art, the invention discloses the method for realizing the IP telecommunication network based on the tunnel, which smoothly transits under the condition of lower cost and not changing the prior network structure so as to realize end-to-end service quality guarantee for users and provide service of multiple IP QoS levels according to requirement for users. The invention adopts a technical proposal that: a plurality of independent resource domains are formed through planning a physical network. A resource tunnel of a domain is established in the resource domain, and data traffics with different service quality requirements are classified into different resource tunnels, thereby realizing that user data traffic can be transmitted in a resource tunnel in accordance with the user requirement on IP QoS level, ...

Rapid rerouting method for protecting local path

Номер: CN0101562536B

Принадлежит:

The invention discloses a rapid rerouting method for protecting a local path, which comprises the following step that: a bypass LSP is established among nodes of the local path of a main LSP needed todeploy rapid rerouting; an outgoing interface of a local restoration point and an incoming interface of a confluent point which a main tunnel passes through are deployed with fault detection; after the local restoration point detects a fault, service traffic is switched to the protective LSP for transmitting; simultaneously, a fault indication signal message is sent to a head node of the main tunnel; and the head node of the main tunnel receives the fault indication signal message and tries to establish a new main LSP. The method avoids the problems that in the prior path protection, the timefor transferring a fault informing message is too long and the range of paths needing to be protected in the local protection is limited, and can implement fault protection among random nodes of themain ...

Method for extending MPLS VPN access through public network and PE equipment

Номер: CN0102082738A
Автор: LIANGGANG QIAO, HAIBING XU, GAOJIN LIU, QIAO LIANGGANG, XU HAIBING, LIU GAOJIN
Принадлежит:

The invention provides a method for extending multi-protocol label switching (MPLS) virtual private network (VPN) access through a public network and provider edge (PE) equipment. The method is applied to the public network comprising MPLS network PE equipment and access network PE equipment. The method comprises the following steps of: creating a virtual interface on the MPLS network PE equipment, associating corresponding virtual routing forward (VRF) for the virtual interface, and configuring an internet protocol (IP) address; and configuring the same encapsulation protocol as the access network PE equipment on the virtual interface, establishing a pseudo wire (PW) between the MPLS network PE equipment and the access network PE equipment by using the public network, and binding the virtual interface and the PW. The method can improve the forwarding velocity of the message and reduce the transmission time delay of the message.

Rapid roaming method for WAPI wireless network

Номер: CN115915315A
Автор: LIU GAOJIN, ZHAO CHENDI
Принадлежит:

A WAPI wireless network rapid roaming method comprises the following steps: when a wireless terminal STA wants to roam and switch from a currently connected wireless access point first AP to a second AP, the STA and the second AP firstly carry out WAPI pre-authentication before switching, if both the STA and the second AP pass the pre-authentication, key negotiation including unicast key negotiation and multicast key notification is immediately carried out in advance, and if the two parties pass the pre-authentication, key negotiation is carried out in advance; and after the process is completed, the STA disconnects the wireless connection with the first AP, establishes wireless association with the second AP, and installs a secret key and opens a controlled communication port based on a result of negotiating the secret key in advance after association with the second AP, thereby completing roaming switching. Compared with a common WAPI pre-authentication method, the method has the advantages ...
