| UDP versus TCP (continued). |
|
|
|
| Both TCP and UDP split data into |
|
|
|
| packets called “datagrams.” However, |
|
|
|
| TCP includes extra headers in the |
|
|
|
| datagram to enable retransmission of |
|
|
|
| lost packets and reassembly of packets |
|
|
|
| into their correct order if they arrive out |
|
|
|
| of order. UDP does not provide this. |
|
|
|
| Lost UDP packets are unretrievable; |
|
|
|
| that is, |
|
|
|
| cannot be reconstituted in their proper |
|
|
|
| order.. |
|
|
|
| Despite these obvious disadvantages, |
|
|
|
| UDP packets can be transmitted much |
|
|
|
| faster than TCP packets |
|
|
|
| three times faster. In certain |
|
|
|
| applications, like audio and video data |
|
|
|
| transmission, the need for high speed |
|
|
|
| outweighs the need for verified data |
|
|
|
| integrity. Sound or pictures often |
|
|
|
| remain intelligible despite a certain |
|
|
|
| amount of lost or disordered data |
|
|
|
| packets (which appear as static). |
|
| IP | n.n.n.n | IP address of the MultiVOIP. For an IP |
|
| Address | 0 - 255 | address to be displayed here, the |
|
|
|
| MultiVOIP must have DHCP enabled. |
|
|
|
| Its IP address, in such a case, is |
|
|
|
| assigned by the DHCP server. |
|
| “Clear” | Clears packet tallies from memory. |
