Live Streaming CDN with Low-Latency Delivery

Built for shopping streams, esports, shows and online classrooms. Broadcasters ingest at the nearest edge, one source becomes a full bitrate ladder, and viewers watch with second-level latency — while launch spikes and DDoS floods are absorbed by the same network.

The four things that ruin a live event

A live stream is a one-shot business. Buffering, lag and outages all happen inside that ninety-minute window, and no amount of tuning afterwards wins back the audience you lost on air.

  • An unstable uplink becomes artefacts and buffering

    Hosts push from home broadband, 4G/5G or venue Wi-Fi. Jitter and packet loss on the uplink surface as macroblocking, audio drift and endless rebuffering — and one dropped stream sends concurrent viewers off a cliff that takes fifteen minutes to climb back.

  • Latency you cannot get down, interaction out of sync

    A standard HLS chain runs 20-30 seconds end to end. By the time the host says “the link is live”, viewers are still a segment behind, so giveaways, Q&A and co-host battles all land off-beat. Simply shortening segments only makes weak-network viewers buffer more.

  • The concurrency spike at showtime

    Seconds after the reminder push, hundreds of thousands of viewers open the player at once. Origin bandwidth, transcoding capacity and the auth endpoint saturate together, and the rebuffer ratio in the first ten minutes decides retention and GMV for the entire session.

  • Hotlinking, piracy and attacks on the ingest domain

    Playback URLs are lifted onto third-party sites that ride your bandwidth, and paid content is recorded and resold. Worse, an attacker can point a DDoS or CC flood straight at your ingest domain and take the whole broadcast off air.

Six capabilities behind every broadcast

Ingest, transcoding, delivery and protection run on one network — nothing extra to chain in for low latency, and no additional forwarding hop.

  • Ingest at the nearest edge

    3,000+ edge nodes accept RTMP and SRT ingest, so hosts connect locally instead of dialling into a central datacentre. Playback over HLS, HTTP-FLV and low-latency HLS works with OBS and standard mobile SDKs unchanged.

  • Private backbone transport with failover

    Streams travel home across 300+ PNIs and 14 Tier-1 backbones rather than congested public transit. Paths are re-scored in real time and switch automatically on degradation, with primary and backup ingest endpoints live at the same time.

  • Adaptive bitrate transcoding

    One ingested source is transcoded at the edge into a 1080p/720p/540p/360p ladder, so players downshift instead of dropping out on weak networks. Repackaging, dynamic watermarking and thumbnail capture are included.

  • Second-level latency, spike-proof delivery

    Low-latency protocols with a 1-2 second GOP bring end-to-end delay down to 1-3 seconds. Mid-tier shielding collapses fetches so a stream is pulled from origin once, and edge bandwidth scales on demand when a million requests arrive in the same minute.

  • Hotlink protection, token auth and concurrency limits

    Referer allow and deny lists, timestamped URL signatures and ingest stream keys give three layers of validation. Cap concurrent sessions, IP count and lifetime per token, and trace leaks with per-viewer dynamic watermarks.

  • Terabit protection on ingest and playback

    Both the ingest and the playback domain sit behind scrubbing. 7T+ of capacity absorbs volumetric floods and high-frequency CC at the edge, while origin and transcoding IPs stay hidden so there is nothing left to hit directly.

Four steps to go on air today

No changes to your encoder or your player SDK — cutover and rollback are both a single DNS change.

  1. Create your stream domains

    Register an ingest domain and a playback domain, then choose regions, playback protocols and whether low-latency mode is on.

  2. Set transcoding and auth

    Define the bitrate ladder plus recording and replay policy, then enable hotlink protection, URL signing and ingest stream keys.

  3. Repoint DNS and test-push

    CNAME both domains to the endpoints we assign, then validate time to first frame, end-to-end latency and player compatibility with a test stream.

  4. Monitor and tune on air

    Watch concurrent viewers, rebuffer ratio, first frame and up/downstream bitrate live, trace any individual stream, and adjust the ladder from real data.

Typical results after onboarding

Ranges observed across shopping, show and event streaming customers; actual results depend on uplink quality, how the bitrate ladder is configured and where your audience sits.

Live streaming acceleration FAQ

First separate uplink from delivery. Check the ingest quality dashboard for upstream bitrate and packet loss: a saw-tooth curve means the bottleneck is the broadcaster’s own connection, so switch to SRT ingest with retransmission on, drop the bitrate from 6Mbps to 3-4Mbps, disable B-frames and use a wired link. If the uplink is steady but viewers still stall, a single high bitrate is the culprit — enable the transcoding ladder so players downshift on their own.

It depends on the protocol. Standard HLS with 6-10 second segments typically lands at 20-30 seconds end to end. Switching to HTTP-FLV or low-latency HLS with a 1-2 second GOP usually brings that to 1-3 seconds, enough for live selling, giveaways and chat to feel in sync. Low latency does shrink the player buffer, so we recommend tiering it: healthy connections get the low-latency path, weak ones fall back to standard HLS automatically.

No, provided three things are set up beforehand. Pre-warm the watch page and player assets thirty minutes ahead so the first paint never touches origin. Enable mid-tier shielding so a stream is fetched from origin once and redistributed between edges. Finally, jitter the reminder push over 30-60 seconds so clients do not all hit auth and playback in the same instant. Edge bandwidth itself scales elastically — no manual capacity request needed.

Layer four controls. Use Referer allow and deny lists to filter off-site embedding. Enable timestamped URL signing with a lifetime under five minutes, signed server-side, with the key never exposed to the front end. Cap concurrent sessions and IPs per token and auto-ban outliers. For paid content, turn on per-viewer dynamic watermarks so a leaked recording identifies the account. On the ingest side, stream keys stop anyone hijacking your channel.

The pattern is ingest locally, transport privately. The host connects to an edge node in their own region, and the cross-border leg runs over our private backbone with 14 Tier-1 direct interconnects instead of congested international transit. Viewers are served from their local edge in the same way, and mainland China audiences can add CN2 routes. Advise hosts to use wired networking, hold bitrate at 3-4Mbps and enable SRT retransmission — intercontinental streams gain the most.

No. With recording enabled, the live stream is written to HLS or MP4 files in fixed-length pieces, and a replay URL is available the moment the broadcast ends, reusing the same domain, auth and caching configuration. You can cut highlight clips by time range, auto-generate cover thumbnails, and have recordings delivered straight into your own object storage for editing and redistribution.
