在 kernel/Document/networking/bonding.txt文档中有关于高可用性介绍中有说道:
11.2 High Availability in a Multiple Switch Topology
----------------------------------------------------
With multiple switches, the configuration of bonding and the
network changes dramatically. In multiple switch topologies, there is
a trade off between network availability and usable bandwidth.
Below is a sample network, configured to maximize the
availability of the network:
| |
|port3 port3|
+-----+----+ +-----+----+
| |port2 ISL port2| |
| switch A +--------------------------+ switch B |
| | | |
+-----+----+ +-----+-----+
|port1 port1|
| +-------+ |
+-------------+ host1+---------------+
eth0 +-------+ eth1
In this configuration, there is a link between the two
switches (ISL, or inter switch link), and multiple ports connecting to
the outside world ("port3" on each switch). There is no technical
reason that this could not be extended to a third switch.
这里的ISL指的是两个交换机间有个链路相通还是说是运行思科的ISL协议的两个交换机……ISL协议负责的是VLAN的中继? |
