SFP Module 18
Quality of Service (QoS) - GbE interface Selectable priority schemes (with 8* traffic queues) • • • • • •
IP header DSCP/TOS VLAN (802.1p user priority) pVLAN ID Protocol * MPLS TC (formerly EXP) * Port (Ethernet ingress ports)
Classifier Mixed ingress traffic
Priority queue 1-8 Scheduler
Scheduling Modes
• Strict Queuing - All top priority packets are send before next queue is served
• Fair Queuing - An weighting is applied to the eight* queues.
• Mixed Mode Queuing* - One/Two Strict queues + 6 Fair queues 19
* GIC unit only, mIFU used 4 queues
Multichannel aggregation • LCA (Link Capacity Aggregation) is an effective technology for multi-channel aggregation of Ethernet traffic • Works on physical layer and is independent of frame type and packet sizes • Automatically scales the Ethernet WAN “pipe” with available channels/links • IEEE 802.1 Link Aggregation does not work well with single “flows” Note
Note: If a link is used between two MPLS switches the Ethernet segment is a single flow as the MAC address is the same for all packets and the IP address is “hidden” behind the MPLS tag

Podmínky poskytování služeb pronajatých okruhů Podle § 269 odst. 2 zákona č.513/1991 Sb., obchodního zákoníku, v platném znění a v souladu se zákonem č. 127/2005 Sb., o elektronických komunikacích • Použitá rádiová technologie: MW zařízení typu Evolution Series • Délka smlouvy 12, 24, 36 měsíců, lze poskytovat službu na 3 – 6 měsíců • Dostupnost spoje 99,95 % času – kvalita služby je prioritou, • „VALUE FOR MONEY“
• Reakční doba a doba odstranění poruchy v závislosti na prioritě spoje a naléhavosti závady • Službu lze poskytovat i v nelicencovaných pásmech, pro speciální uživatele • Cena služby: základní cena služby poskytované na spoji ve „standardním provedení“, t.j. montáž vlastní MW technologie, antény 2 x 0,6 m, délky kabelů 2 x 50 m, stávající napájení 48 V DC, instalace vnitřní jednotky do stávajícího stojanu, montáž nosné konstrukce pro anténu jednoduchý výložník). Při jiném, než „standardním provedení“ (velikost a typ antén, dodání záloh. zdroje 48 V DC, nový 19´´ stojan, dlouhé kabelové trasy, nosné konstrukce antén většího rozsahu) budou tyto dodatečné položky kalkulovány formou zřizovacího poplatku. Tento poplatek může být uhrazen jednorázově, při aktivaci služby, nebo rozpočítán do ceny služby. Při zvýšení přenosové kapacity již provozovaných služeb, bude účtována pouze cena nové služby dle ceníku, bez dalších poplatků. NEPLAŤTE DNES ZA KAPACITU, KTEROU VYUŽIJETE AŽ ZÍTRA ...
