[QUOTE="quickshare2, post: 31224468, member: 101712"] Consortium cable එක [B]Layer 1 physical path[/B] එක handle කරනවා — ඒක හරි. Traffic forward වෙන්නේ [B]Layer 3 (IP/BGP)[/B] මතයි, consortium එක centralized කරලා route decide කරන එකක් නෙවෙයි. Landing point example colombo exchange එකෙන් පස්සේ traffic යන්නේ [B]SLT AS45489 → peering / transit networks → destination AS[/B] කියන hops හරහා. ඒ අතර [B]international backbone networks[/B] (NTT, Tata, Telia, Lumen වගේ) traffic forward කරනවා. [B]SLT international transit සඳහා මුදල් ගෙවන්නේ[/B] [LIST] [*][B]Capacity basis[/B] (10 Gbps / 100 Gbps ports) [*]හෝ [B]95th percentile bandwidth usage[/B] මත කියන commercial models වලින්. Peering free වෙන්න පුළුවන්, [B]transit always paid[/B]. [/LIST] අද බොහෝ links [B]10G / 100G[/B] වුණත්, quality depend වෙන්නේ [B]routing policy, peering openness, congestion control[/B] මතයි — speed ports වලින් විතරක් නෙවෙයි. Simple truth එක: [B]Cable consortium = road[/B], [B]Transit = toll-paid highways[/B], [B]BGP = GPS routing[/B]. [B]International transit price[/B] එක එකම rate එකක් නෙවෙයි — factor කිහිපයක් මත උඩටත්, පහළටත් වෙනස් වෙනවා. [B]Price උඩ යන්නේ[/B]: [LIST] [*]Premium routes (low-latency, fewer hops) ගත්තොත් [*]Tier-1 backbones (Telia, NTT, Lumen වගේ) direct transit ගත්තොත් [*]Guaranteed capacity / SLA (no congestion) තියෙන contracts [*]Peak usage වැඩි වෙද්දී (95th percentile high) [/LIST] [B]Price පහළ යන්නේ[/B]: [LIST] [*]Cheap / indirect routes ගත්තොත් [*]Congested or longer paths accept කළොත් [*]Volume වැඩි කරලා bulk contracts ගත්තොත් [*]IX peering වැඩි කරලා paid transit reduce කළොත් [/LIST] ඒ නිසා ISP එකක් [B]cost down කරන්න cheap transit choose කරයි[/B], [B]quality improve කරන්න premium transit choose කරයි[/B] — දෙකම trade-off. Simple line එක: [B]Cheap transit = more hops / more latency Premium transit = less hops / better performance[/B] SLT [B]Tier 2 network එකක්[/B], global reachability හදාගන්න [B]Tier 1 backbones සමඟ paid transit + peering[/B] කරනවා — Layer 3 (BGP) හරහා. [B]IP addresses සහ ASN assign වෙන්නේ[/B]: [LIST] [*]Global level එකේ [B]IANA[/B] [*]Regional level එකේ [B]RIR[/B] (අපේ region එකට [B]APNIC[/B]) [*]APNIC → ISP (SLT වගේ) ට [B]IP blocks + ASN[/B] assign කරනවා [*]ඒ ASN එක භාවිතා කරලා [B]BGP මඟින් routes announce කරන්නේ[/B] [/LIST] [B]IP ownership හෝ routing control[/B] ඒ consortium එකට automatically යන්නෙ නෑ. Layer 1 (fiber) physical path එක. Layer 3 (IP + ASN + BGP) තමයි [B]internet reachability decide කරන්නේ[/B]. Simple truth එක: [B]ASN + IP APNIC දෙනවා,[/B] [B]Tier 2 ISP Tier 1 එකට pay කරලා global internet එක reach කරනවා[/B]. [B]Cost save කරන්න ISPලා traffic “shape / scrape” කරන විදිහ[/B]: [LIST] [*][B]Traffic shaping / throttling[/B] (certain ports, protocols, peak hours) [*][B]QoS policies[/B] දාලා heavy traffic (torrent, video) slow කරනවා [*][B]Caching / local CDNs[/B] (YouTube, Netflix) prefer කරලා paid transit අඩු කරනවා [*][B]Cheap transit routes[/B] prefer කරලා premium paths avoid කරනවා [*][B]Peak-time congestion allow කරනවා[/B] instead of buying more capacity [/LIST] මේවා කරන්නේ [B]international transit cost අඩු කරන්න[/B]. Userට feel වෙන්නේ speed/latency drop වුණා වගේ. Layer 1 cable තියෙන එක alone solution එක නෙවෙයි. [B]Layer 3 routing + traffic management decisions[/B] තමයි real performance decide කරන්නේ [/QUOTE]
