TCPIP Page
The TCPIP page shows recent TCP/IP activity to and from the current system.
TCP/IP (Transmission Control Protocol/Internet Protocol) is one means by which computers communicate across a network. It is the basic protocol used for communication across the Internet.
Communication programs that use the TCP/IP protocol are built in two layers:
- The TCP layer converts a data stream into a series of packets for transmission across a network. When these packets are received at their destination, another TCP layer reassembles the data stream.
- The IP layer ensures that data packets reach the right destination.
To open the TCPIP page

Charts on the TCPIP page
Notes:
- Click an item in the legend to highlight its series (line) in the chart. Click a second time to return the series to its normal appearance.
- Move the mouse pointer over an item in the legend to view the current value for that series within the chart.

| TCP Segments |
When TCP transfers a stream data, it breaks up the stream into small segments. The TCP Segments chart displays three different graphs representing the rate at which TCP segments are transmitted or received in the current Windows system.
Sent, Received and Retransmitted are each represented by a single line on the chart, and by an item in the legend at the right of the chart. | ||||||||||||||||||||||||
| IP Fragments |
When data packets are transmitted across a network via TCP/IP, they may be further fragmented en route, and need to be reassembled. The IP Fragments chart displays the rates at which the fragmented packets are received and rebuilt. The graphs on the chart display one of the following features of IP fragmentation:
Each data series in the IP Fragments chart is represented by a single line, and by an item in the legend at the right of the chart. | ||||||||||||||||||||||||
| UDP Datagrams |
UDP (User Datagram Protocol) is an alternative communications protocol to the Transmission Control Protocol (TCP). Unlike TCP, UDP does not provide a sequencing service, so when UDP datagrams (packets) arrive at a destination, they are reassembled into a complete message via an end-point application that is active on the port(s) specified in the datagram. The UDP Datagrams chart displays three different graphs representing the rate at which UDP datagrams are transmitted or received in the current Windows system.
Sent, Received and No Port are each represented by a single line on the chart, and by an item in the legend at the right of the chart. | ||||||||||||||||||||||||
| IP Datagrams / IP Datagram Errors |
IP datagrams (packets) are the message units that are transmitted across a network (and across the Internet) via the Internet Protocol. Use the IP Datagrams control to choose to view IP Datagrams or IP Datagram Errors. The IP Datagrams chart: The rate at which IP packets are sent, received, and routed to other destinations.
The IP Datagram Errors chart: The number of errors that occur when IP packets are sent, received, and routed to other destinations.
