The value of information technology to an organization is based upon how effectively it can help support business goals and objectives.  Today most large organizations rely heavily on their networked   infrastructure, a vitally important strategic asset that supports the distributed enterprise -- linking people, processes, and information.  It is imperative to move beyond reactive management techniques and assume a more proactive approach by employing techniques for network performance analysis and  optimization.  TGC can provide the services needed to ensure the health, availability, and maximum  performance of a customer's network. 

Network performance is a measure of a network's throughput -- the amount of data transferred from one place on the network to another in a specified amount of time.  Data transfer rates for networks are measured in terms of throughput.  Typically, throughputs are measured in kilobits per second (Kbps), megabits per second (Mbps) and gigabits per second (Gbps).  Besides measuring the bandwidth of a network, network performance also takes into account how fast a piece of data travels from one part of the network to  another.  Finally, network performance takes into account dropped (lost) network packets.  By these measures, a high performance network has high bandwidth, quick data transfer rates, and low rates of packet loss.

TGC utilizes a custom suite of tools that can be used to measure performance on a network segment.  Simple Network Management Protocol (SNMP) is often used to gather statistics (such as the number and size of IP packets, total bytes, router CPU utilization, and discarded packets) across many network devices.  Network monitoring tools and protocols can be used to display bandwidth usage and other  information over time.  Like all measures, performance measures are largely subjective -- good and bad performance needs to be defined for each organization.
