Παιδιά καλησπέρα..
Θα ήθελα τη βοήθεια σας στην ερμηνεία των παρακάτω στοιχείων από το NDT σε σχέση με τα στατιστικά της γραμμής μου - το modem είναι το Sagem 2404.
Statistics από το NDT
ink set to Half Duplex mode
No network congestion discovered.
Good network cable(s) found
Normal duplex operation found.
Web100 reports the Round trip time = 30.83 msec; the Packet size = 0 Bytes; and
There were 9 packets retransmitted, 46 duplicate acks received, and 48 SACK blocks received
The connection stalled 1 times due to packet loss
The connection was idle 0 seconds (0%) of the time
This connection is receiver limited 38.96% of the time.
This connection is network limited 60.83% of the time.
Contact your local network administrator to report a network problem
Web100 reports TCP negotiated the optional Performance Settings to:
RFC 2018 Selective Acknowledgment: ON
RFC 896 Nagle Algorithm: ON
RFC 3168 Explicit Congestion Notification: OFF
RFC 1323 Time Stamping: OFF
RFC 1323 Window Scaling: OFF
Information: Network Middlebox is modifying MSS variable
Server IP addresses are preserved End-to-End
Information: Network Address Translation (NAT) box is modifying the Client's IP address
Server says [85.75.126.182] but Client says [192.168.1.5]
Statistics από το modem..
Statistics -- ADSL
Mode:ADSL2+ Line Coding:Trellis On Status:No Defect Link Power State:L0 DownstreamUpstreamSNR Margin (dB):15.2 29.8 Attenuation (dB):31.5 14.1 Output Power (dBm):12.3 19.4 Attainable Rate (Kbps):13276 1085 Rate (Kbps):8191 381 MSGc (number of bytes in overhead channel message):59 16 B (number of bytes in Mux Data Frame):254 11 M (number of Mux Data Frames in FEC Data Frame):1 1 T (Mux Data Frames over sync bytes):1 3 R (number of check bytes in FEC Data Frame):0 0 S (ratio of FEC over PMD Data Frame length):0.9922 0.9796 L (number of bits in PMD Data Frame):2056 98 D (interleaver depth):1 1 Delay (msec):0 0 Super Frames:136670 316819 Super Frame Errors:46 0 RS Words:0 0 RS Correctable Errors:0 0 RS Uncorrectable Errors:0 N/A HEC Errors:34 0 OCD Errors:2 0 LCD Errors:0 0 Total Cells:97928825 2939417959 Data Cells:1205615 122165161 Bit Errors:0 43589 Total ES:118 53 Total SES:0 11 Total UAS:16 4216257
Από ότι καταλαβαίνω το SNR και το Attenuation είναι καλά μεν αλλά όχι εξαιρετικά..
Και το download είναι maximum μισό της γραμμής.
Μπορώ να κάνω κάτι για να τα βελτιώσω;
Ευχαριστώ πολύ!
