Problems solved by technology

[0004] With the continuous growth of services, the forwarding performance requirements of new services for equipment carrying network data products are also constantly improving. When operators deploy mixed old and new equipment, if the routing and forwarding method in related technologies is still used for business Packet forwarding may forward some services that require high forwarding performance of devices to devices with low forwarding performance, and forward some services that require low forwarding performance of devices to devices with better performance. Reasonable utilization of network resources, resulting in a decline in the quality of service of the entire network

Embodiment approach

[0045] Preferably, for the above two preferred implementation manners, the method further includes: the network device searches the global routing table and obtains the forwarding outgoing interface, and the device belongs to the device corresponding to the forwarding outgoing interface. The method ensures that the determined network equipment can correctly reach the equipment on the destination interface.

[0046] Preferably, the capability map or the route map has an interface for user configuration. It can provide users with more personalized services and improve user experience.

example 1

[0048] This example describes in detail the structural composition of the network equipment that can realize the above method and the process of forwarding using the network equipment. Figure 5 It is a structural block diagram of a network device according to preferred example 1 of the present invention, and the structural composition of the network device includes:

[0049] The performance detection module 52 is configured to detect and provide the forwarding performance of neighboring devices in real time, and create forwarding performance groups to distinguish neighboring devices with different performances in different forwarding groups.

[0050] The policy configuration module 54 is configured to perform specific policy configuration of the Match item rule and the Set item forwarding entry of the routing map, and may provide the user with an interface or an interface for policy configuration.

[0051] The matching and forwarding module 56 is configured to classify the pa...

example 2

[0059] Figure 6 It is a schematic diagram of a network application scenario according to the preferred example 2 of the present invention. An exemplary networking structure is: a CE device and a PE0 device are connected through an interface fei_1 / 10, and the network side corresponding to the CE device can provide common Internet services, 3GVOICE, and IPTV and other service types. PE0 has two neighbor forwarding devices PE1 and PE2, where:

[0060] The forwarding performance of PE1 is average, and it is suitable for forwarding common Internet services. PE0 and PE1 are connected through interface fei_1 / 30;

[0061] PE2 has strong forwarding performance and can meet the needs of new service applications such as 3G VOICE. PE0 and PE2 are connected through interface fei_1 / 20.

[0062] Among the different services provided by the CE side network, services such as 3G VOICE and IPTV have strong timeliness requirements and require continuity and high-throughput guarantees. These se...

Abstract

The invention discloses a route forwarding method used for an IP network and network equipment. The method comprises the following steps that: the network equipment determines equipment which meets the requirement of forwarding a service message in a service type according to the service type of the received service message; and the network equipment forwards the service message to the equipment. The route forwarding method used for the IP network and the network equipment utilize network resources reasonably, thereby improving the quality of network service.

Description

technical field [0001] The present invention relates to the communication field, in particular to a routing and forwarding method and network equipment for an Internet Protocol (IP) network. Background technique [0002] With the development of network technology and the application of IP technology in the next generation network, IP Television (IPTV for short) and other service bearer fields, the IP network has gradually evolved from a simple Internet and data service bearer network to one capable of carrying data, Multi-service bearer network for voice, video and other services. [0003] In related technologies, common routing and forwarding technologies search the routing table according to the destination address of the message to obtain the forwarding interface or next hop. The policy routing forwarding technology is based on packet access control list (Access Control List, referred to as ACL) five-tuple (source address, destination address, source port, destination po...
