Is implementing an MPLS network worth the extra money?
Posted on 2009-12-21
My company has a main office and 15 other branch offices connected to the main office via SonicWALL VPN. We utilize terminal services and VoIP throughout the network that route back to the main office.
Our network has been experiencing slow-downs and congestion. We found out that our dual T1 lines (1.5 Mbps each) at the main office becomes very congested during peak hours. In the next year we expect a higher volume of data and voice traffic. Our ISP suggested that we upgrade to MPLS instead of the method we have now, which is purely through the public internet.
We're thinking about upgrading one of the lines to 3 Mbps MPLS and having the other a 3 Mbps Internet line or just having both be 3 Mbps internet lines. Implementing MPLS would be costly because the lines coming from the branch offices would also have to be upgraded to MPLS.
My question is would MPLS really be worth it? I know MPLS improves response times and supports QoS. However, our SonicWALLs provide things like QoS already. Would upgrading the T1 lines from 1.5 Mbps to 3 Mbps be enough of an upgrade or does adding MPLS really provide some significant features that our network can really benefit from? Any feedback or ideas would be greatly appreciated. Thanks in advance :)
