We've recently installed several 100 Mb Comcast ENS circuits and after testing the bandwidth across them; I've noticed a severe speed issue. In order to test the speeds I've been running regular file transfer tests from Windows boxes and also been running tests with the LANSpeed test program. Does anyone have any suggestions on how I can further test the speeds between the sites? I need to be able to prove to Comcast that it's a problem with their network and not my equipment. Below is breakdown of our network setup:<br />
<br />
2911 at our Admin location, acts as the hub for all sites. The G0/0/0 interface is setup as a sub-interface with a separate vlans assigned to each remote location.<br />
<br />
2811 at each remote location, all with the same config. The only differences are the VOIP numbers at each location and the vlan assigned to the location.<br />
<br />
Is there a bandwidth test that I can run from router to router that will give me the information I need?

Bandwidth Speed Tests across LAN

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).

Network Analysis

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.

TCP/IP

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
