公司近期內可能有這方面的需求..
要把多條不同ISP的T1專線..
頻寬合併成T1*2 or T1*3
因為之前沒有接觸過這方面的設備...
想請教各位...
這方面有哪些相關的整合方案呢?..
軟硬體的都可以....最好在大概附上所需設備(軟硬體)的價格...
因為ISP好像只能做自己專線的Load-balance而已..
一旦要到多ISP..
還要考慮到IP也是不同區段的問題...(因為主要作為server用途)
好像還蠻棘手的...
另外...稍微查了一下Cisco 1720的說明...在上面
有下面這些字樣
DLSw+ Enhanced Load Balancing
In a network with multiple capable paths,
the DLSw+ Load Balancing Enhancements feature improves traffic load balancing
between peers by distributing new circuits based on existing loads and
the desired ratio.
For each capable peer (peers that have the lowest or equal cost
specified), the DLSw+ Load Balancing feature calculates the difference
between the desired and the actual ratio of circuits being used on a peer.
It detects the path that is underloaded in comparison to the other capable
peers and assigns new circuits to that path until the desired ratio is achieved.
Multilink Inverse Multiplexer
The Multilink Point to Point Protocol (MLP) Inverse Multiplexer feature
allows you to combine multiple T1/E1 lines in a Versatile Interface
Processor (VIP) T1/E1 interface into a bundle that has the combined
bandwidth of the multiple T1/E1 lines. This is done by using a VIP MLP
link. You choose the number of bundles and the number of T1/E1 lines in
each bundle. This allows you to increase the bandwidth of you network
links beyond that of a single T1/E1 line without having to purchase a
T3 line.
從上面這些敘述看起來...似乎我們可以不必再多採購任何硬體設備...
就可以直接在Cisco 1720上面玩出Load-Balance的功能?
