WAN Connectivity Options

Just looking for opinions and thoughts on the options available etc.

We have a flat LAN in the UK on a private IP range 10.213.X.X.
We connect to a sister company in the US on an IP range of 10.80.X.X.
We have a domain trust, integrated DNS and connect to each other via Verizon MPLS.
Both sites use Cisco ASA firewalls.

In the UK we have just leased a new Warehouse with office space some 50 miles from the main UK facility and need to connect this to the main UK facility as well as the US network.

Options as I initially see them:

1) Connect the new warehouse to the MPLS.
 - Can connect 1 to many via IP subnet thus network traffic can be routed to any location from  the new warehouse.
- Would get quality of service and service level agreement.
- Expensive.
- Traffic would be increased down the MPLS to the main UK location from the new site.
 although current statistics suggest the existing MPLS isn’t being over worked at all and I could add another E1.

2) Dedicated BT circuit from the new site to the main UK office.
- Presumably cheaper than another MPLS connection.
- No increased load on the existing MPLS in terms of UK bound traffic.
3) Fast connection to the Internet (Ethernet Last Mile) at the new location connecting to a Bonded ADSL at the main UK site.
- Potentially cheapest solution.
- No service level agreement on the ADSL side..
- No overall responsivility for the connection.

All thoughts comments are welcome.

    Accepted Solution

    I'd go with MPLS, unless options 2 or 3 have considerably lower costs.  MPLS is private and will be supported with SLA's.  The other options are cheaper, but insecure and less reliable

    Assisted Solution

    Option1: Ideal for business. Secure, Reliable, No Complications, No extra config

    Option 2: Will increase the traffic between UK & US, as all traffic from the new warehouse have to passthru UK office to reach US office. unless you have WAN accelerator between US & UK.

    Option3: Unreliable. Again it all depends on how important is the new office.
