Firstly reassessment of your optimisation and QoS parameters needs to be undertaken. Without a proper allocation of WAN resources, applications will perform badly. Network congestion creates both a lack of bandwidth and extra router delay that jointly contribute to degrading the performance of applications. You cannot count solely on compression to deal with the lack of bandwidth. Compression creates virtual “free” bandwidth, but the amount of bandwidth created varies over time depending on the amount of redundancy in the flows.
Compression is NOT a replacement for advanced QoS methods
Furthermore, deploying acceleration without having implemented proper optimisation can be dangerous for application performance. Acceleration solutions without advanced QoS capabilities can actually worsen congestion when it occurs, especially in MPLS networks with meshed topologies.
- How will your network behave with the new application running ?
- How will the new application affect the other network application’s performance which are also critical to the business ?
- You think that you will need 3 to 6 months and perhaps some consulting help to roll-out this new application correctly but you need some help to justify this spend both in terms of the political situation and also the financial one.
You have already tested the new application in your lab and collected network performance and capacity data to ensure that the network will support the new traffic. To be safe, you also ran a pilot with a limited number of end-users. you will then design adequate policies that guarantee the new application performance while protecting existing ones.
Finally, you have implemented these policies device by device and been monitoring and manually adjusting them. If you have been careful you most probably have over-provision your links and their capacity as its better to over specify than under. The obvious question now is do you know if this new application will seamlessly roll in as per your expectations or do you need something concrete to ensure that it will actually work.
