Embodiment 1

[0045] see figure 2 , a flowchart of a method for deploying a traffic engineering TE tunnel provided in Embodiment 1 of the present invention. This embodiment provides a method for deploying a traffic engineering TE tunnel, and the method includes the following steps:

[0046] Step 201: Store the TEDB on the server. In this embodiment, the network management server is taken as an example, and the TEDB is stored on the network management server. When a TE tunnel is created, the configuration information of the TE tunnel (source / sink / configured bandwidth / other constraints) ) to the network management server.

[0047] For example, the TEDB of the entire network is saved on each device, here it is only necessary to copy one TEDB from one device to the network management server.

[0048] Step 202: The network administrator pre-configures the configuration information of the TE tunnel on the network management server.

[0049] Step 203: After the pre-configuration is completed, ...

Embodiment 2

[0063] see image 3 , is a schematic diagram of an apparatus for deploying a traffic engineering TE tunnel according to Embodiment 2 of the present invention. This embodiment provides a device for deploying a traffic engineering TE tunnel, where the traffic engineering database TEDB is pre-stored in the device.

[0064] The device includes:

[0065] TEDB storage and maintenance module, used to store and maintain the traffic engineering database TEDB;

[0066] The TE tunnel calculation module is used to calculate the TE tunnel path according to the data in the TEDB storage and maintenance module and the configuration information of the pre-deployed TE tunnel; or when the calculated TE tunnel path is unreasonable, the newly added constraint is used as the The configuration information of the TE tunnel recalculates the TE tunnel path;

[0067] The path analysis module is used to trigger the TEDB storage and maintenance module to modify the original TEDB according to the TE tun...

Embodiment 3

[0071] see Figure 4 , is a schematic diagram of a system for deploying a traffic engineering TE tunnel according to Embodiment 3 of the present invention. This embodiment provides a system for deploying a traffic engineering TE tunnel, including a server and a device,

[0072] Among them, the server includes:

[0073] TEDB storage and maintenance module, used to store and maintain the traffic engineering database TEDB;

[0074]The TE tunnel calculation module is used to calculate the TE tunnel path according to the data in the TEDB storage and maintenance module and the configuration information of the pre-deployed TE tunnel; or when the calculated TE tunnel path is unreasonable, the newly added constraint is used as the The configuration information of the TE tunnel recalculates the TE tunnel path;

[0075] The path analysis module is used to trigger the TEDB storage and maintenance module to modify the TEDB according to the TE tunnel path after the TE tunnel calculation ...

Abstract

The invention provides one method, device and system to distribute flow engine channel in network communication field, which comprises the following steps: storing TEDS and set information on servo and computing TE channel path and analyzing whether it is proper, if not, adding binds for new path till it is proper and sending the distribution information to next device. The invention provides one device to distribute the channel, which comprises TEDB memory and sustain module, TE channel computation module, path analysis module and bind adding module and distribution module. The invention also provides one system composed of servo and device.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for deploying traffic engineering TE tunnels. Background technique [0002] With the rapid growth of network resource requirements, the expansion of IP application requirements, and the increasingly fierce market competition, TE (Traffic Engineering, traffic engineering) has become a major application of MPLS (Multiprotocol Label Switching, multi-protocol label switching). Because IP routing follows the principle of the shortest path, it is very difficult to implement traffic engineering on traditional IP networks. Once a traditional IP network selects a path for an IP packet, the IP packet will be transmitted along this path regardless of whether the link is congested, which will cause the entire network to over-utilize resources in some places, while the network in other places will be overutilized. Resources are idle. [0003] In MPLS, traffic en...
