Embodiment Construction

[0043] The core of the present invention is to introduce Super QinQ (aggregation QinQ) technology, thereby realizing the aggregation of QinQ, so as to realize the purpose of saving IP addresses and simplifying configuration operations.

[0044] The specific implementation of the Super QinQ technology provided by the present invention will be described below.

[0045] The Super QinQ (ie aggregated subnet) is to aggregate several QinQs (ie virtual local area network stacking network) into a large subnet, so that each QinQ does not need to specify an IP address, thereby saving IP addresses. And the routes of each QinQ are directly aggregated, that is, the gateway specified by the host under each QinQ is the IP gateway address of this large subnet. That is to provide a mechanism so that the hosts belonging to different QinQs in the same device are allocated in the same IP subnet and use the same default gateway.

[0046] In a large-scale switched local area network environment, t...

Abstract

The invention discloses a stacking network aggregation system and method of virtual local area network, which comrprises the following steps: every virtual local area network stacking network installs one aggregation subnet; the address information is distributed for aggregation subnet; every virtual local area network stacking network uses the address information of aggregation subnet to carry out business interchange treating. The invention imoroves the IP address capacity factor by introducing ggregation subnet, which reduces the extra work amount of network planning, disposaling and servicing.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to an aggregation system and method based on virtual local area network stacking. Background technique [0002] With the widespread application of VLAN (Virtual Local Area Network) technology, especially the use of one VLAN for each user in the MAN, the VLAN ID (VLAN identification) ranging from 0 to 4095 becomes the bottleneck of network development. [0003] To this end, the industry has proposed a QinQ (VLAN stack, VLANStack) technology that expands the number of VLAN IDs to meet the requirements of various networks for VLAN IDs. [0004] In addition, with the continuous maturity and extensive application of the three-layer switch, many enterprise network and some MAN users tend to use the three-layer switch to build the backbone network. , generally do not use VPN (virtual private network) based on MPLS (Multiprotocol Label Switching) or IP protocol, but h...
