Router Charts-WAN to LAN Throughput-Viteza Transfer WAN-LAN

Hai sa nu-i zicem dependenta dar... luati o foaie de hartie in fata si enumerati cateva activitati care le faceti fara calculator. Sunt cam putine nu?
Atunci hai sa vorbim despre calculatoare.

Router Charts - WAN to LAN Throughput
http://www.smallnetbuilder.com/tools/charts/router/view

WAN to LAN Throughput/numit si NAT/ WAN-LAN Durchsatz/Viteza Transfer WAN-LAN
Deci Viteza INTRARE-IESIRE Router, mai precis CANTITATEA de Date care poate fi prelucrata INTERN in ROUTER in unitatea de timp: SECUNDA
MBites/sec.
A NU se confunda cu WLAN/LAN, care in ordine, vine DUPA aceasta prelucrare deci reprezinta pe sfoara nodul urmator.


Este vorba de un aspect ESENTIAL la Router-e, care este in general TRECUT SUB TACERE.

In special la AVM FritzBox, nu am intalnit in nici-o specificatie, cati Mbit/sec poate sa aiba transferul-de-date de la WAN la LAN...
Aveti aici tot felul de Router WLAN, cu transferuri WLAN AC de 1300(5GHz)+ 300/450/turbo: 600Mbits/sec. (2,4 GHz).
Si mai spun si ca sunt CUMULATE benzile, deci hai sa zicem, 2700Mbits/sec. in simultan 5 GHz+2,4 GHz.

DAR: semnalul care ajunge la WLAN-ul teoretic AC de 1300MBits/sec. vine de undeva.
Si anume, tocmai de la acest WAN to LAN Throughput maximal cam peste 900 MBits/sec.


Si trecerea este mai ingusta, maximal 1000 MBits/sec./aici cateva peste 900 MBits/sec., dar de obicei 150- 450 MBits/sec. (Spun gurile rele, pentru ca AVM FritzBox TACE, asa cum am spus mai inainte).

Deci eu am un furtun de suprapresiune care este alimentat de o galeata de apa.

Si mai trebuie si MODEM, daca nu este integrat in.
Intre Router si modem-ul separat, avem asa-zisele LAN Ethernet fie si Gigabit/Ethernet, deci ar transfera 1000 MBits/sec.
Insa ADEVARUL ESTE:
ETHERNET CAT-7 cu RJ 41 transfera MAXIMAL 600 MBits/sec
.
Hai sa zicem: ai performanta TEORETICA in WLAN AC 1300, semnalul emis e acesta Access Pointt este receptionat de un Bridge, legat de computer cu Cablu Ethernet-7/600MBits/sec. Deci automat si TEORETIC pierdere de 700 MBits/sec., fara a mai calcula ATENUAREA si distorsiunile. (2,4 GHz e Banda suprasaturata, toti vecinii o au pe diferite aparate..parca si Mikrowelle/ Cuptorul de Microunde lucreaza ca in aceasta frecventa).


In paranteza fie spus:
Sa mai ai USB2 intr-un Router performant e de rsu-lumii...
Si sa te lauzi ca ai DDR3 256 MB...tot asa.
Sau procesor "performant" 2 kernel, 840MHz....

Cel putin la ASUS, cel cu MODEM VDSL2 integrat, sunt 2 procesoare, separate , dar utilizatorii pe AMAZON (cea mai corecta critica) spun ca INCALZESTE al naibii...




1. Pana atunci, DISCUTIA, pe un forum, chiar daca mai veche (2011, dar de fapt aici nu s-a schimbat nimic in atitudinea AVM) care arata ca NIMENI NU STIE ceva precis, rezultand logic: AVM/FritzBox NU DORESTE sa fie cunoscute datele esentiale, nu le publica in specificatiile tehnice:

The 7390 supports well in excess of 100Mbs wan to lan throughput & most users achieve around 95Mbs (less overheads) with the 100Mb plan.

Router ASUS RT-AC87U

Aici o exemplificare, cu un Router performant, la care WAN to LAN Throughput este peste 900 MBits/sec. (vide Tabelul in LINK-ul initial) dar va rog sa observati TEMPERATURILE, CPU si WLAN (2,4/5GHz):

Welcome to the official website for the Asuswrt-Merlin firmware project, a third party alternative firmware for Asus routers, with a special emphasis on tweaks and fixes rather than radical changes or collecting as many features as possible.

inca un exemplu, de fapt un monstru de Router, ct incalzeste asta, nu spune nimeni:

ASUS RT-AC5300

RT-AC5300 | WLAN & Netzwerk | ASUS Deutschland (desi pe pagina germana, e TOTUL in engleza)

Specifications:

Si ca sa vedeti despre ce MONSTRU este vorba, cititi si in josul paginii, RECLAMA proprie :

https://www.asus.com/de/Networking/RT-AC5300/overview/

asus-rt-ac5300-1500x1000.jpg


ac5300-specs.jpg




Problema este si ramane: In 3x WLAN (1,5 GHz/2,4GHz/5GHz) 3xAC combinate dau TEORETIC 5300 Mbit/sec. (Furtunul de Suprapresiune) DAR cum ramane cu sursa, Galeata care-l umple adica WAN to LAN Throughput rata de transfer WAN-LAN, numita si NAT?
Sau este mai mare? Inca n-am gasit...

Ba da..am gasit tot aici:

USB data transfers enjoy up to over 100 MB/s speed and the router download/upload speed (WAN-LAN throughput) up to 1800 Mbps. 5.

Ma intereseaza Nota 5. si o gasesc tocmai JOS la :

Disclaimers:

1. RT-AC5300 owners get the basic WTFast solution free. The free version is limited to accelerating one device at a time, and includes WTFast technical support. Users can pay to upgrade to the premium version for simultaneous acceleration of multiple devices.
2. Windows is either registered trademarks or trademarks of Microsoft Corporation in the United States and/or other countries.?
3. Mac OS is a trademark of Apple Inc.
4. Linux is the registered trademark of Linus Torvalds in the U.S. and other countries.
5. The actual performance may vary as a result of network conditions and environmental factors.
6. MU-MIMO-certified client(s) required.
7. MU-MIMO beta firmware will be available by the end of 2015.
8. Device speeds vary according to Wi-Fi specifications and environmental factors.


Imi place Nota 1. In esenta, cumperi Router-ul, habar nu am cu cate sute de EUR, dar NU SI TOATA PERFORMANTA, pentru ca trebuie sa platesti in plus, abia dupa aceea beneficiezi de TOATE acceleratiile simultane:

1. RT-AC5300 owners get the basic WTFast solution free. The free version is limited to accelerating one device at a time, and includes WTFast technical support. Users can pay to upgrade to the premium version for simultaneous acceleration of multiple devices.



Parca am mai citit: alimentarea (cu rezerva necesara) cca 19 V, 3 Amperi si ceva, deci consum cca 40-(56)W/Ora?


Exemplele ASUS date sunt ROUTER fara MODEM... adica RT












Si TOTUSI, intr-o analiza cu TESTE, concluzia este ca, chiar in cazul ADSL, ADSL2, VDSL, VDSL2, merita, intrucat viteza de prelucrare creste, cam de 4,5 ori, uneori si mai mult.

Daca regasesc LINK-ul, il dau...
