MPLS Service, how does it work

Hi All,

I am working on an assigment with a company to review their network.

• Current Status
o HO – Data Center with Leased Line & Public IPs
o Branches – about 18, each having between 1 Mbps and 3 Mbps Broadband connections and they connect to the Public IP to use the transaction application hosted on the data center

Now, with MPLS, the following questions arise:

• The speed and limitation of data exchange, if any
• What if, the MPLS circuit goes down
• What is the LAN setup required in each of the branches between the machines
• How will the internet be accessed by the branches – do they still need to have a broadband connectivity or the internet can be only at the HO level and through the MPLS circuit itself, they access the internet as well

Please help me with pointers on these.

MPLS management and implementation requires some GOOD working knowledge of routing.

In my experience, the MPLS will be a T-1 line or better, high availability, but instead of going to the web, it only routes to another location within the same MPLS setup.

You can have one location setup with Internet access and have all the locations go through it, or you can have Internet access at each location and only route traffic through the MPLS when a connection to another site is needed.

It all depends on how the network is designed.

Remember, each location will need a unique subnet that will not conflict with all of the others. Something like this:

Location 1:
Location 2:
Location 3:
