Understanding Akamai's Low Latency Streaming Solutions

Akamai has established itself as a leader in delivering low latency streaming solutions that meet the demands of today's real-time content delivery. For a potential client, understanding the dual nature of their offering is key. Akamai supports both premium out-of-the-box services, where you can ingest a single stream and have it delivered globally at ultra-low latency, as well as flexible building blocks for those who require a highly customizable architecture.

Performance Metrics

At the heart of Akamai's low latency streaming is a focus on minimizing delay and ensuring viewers experience real-time content with minimal buffering. Their performance metrics are underpinned by the following elements:

Ultra-Low Latency (ULL): By leveraging chunked-encoded and chunked-transferred CMAF (Common Media Application Format), Akamai achieves end-to-end latencies ranging typically between 1.5 and 6 seconds. This design is crucial for use cases where near real-time interaction is required.
Low-Latency DASH & HLS: Akamai supports both Low-Latency DASH (LL-DASH) and Low-Latency HLS (LL-HLS) standards, which can help in targeting latencies near 2 seconds when configured correctly.
Chunked Transfer Encoding (CTE): This technique allows for the start of content processing as soon as a chunk is received, rather than waiting for the complete segment. This mechanism is a key contributor to latency reduction.
Real-Time Transcoding: Akamai offers live transcoding capabilities that dynamically adjust streams based on varying network conditions and device capabilities, ensuring a consistent streaming quality.
Edge Computing & CDN Optimization: The extensive network of over 300,000 servers across thousands of locations ensures that content is delivered from locations nearest to the viewer, resulting in reduced round-trip times and optimized latency performance.

These performance metrics not only demonstrate the robust technical capabilities of Akamai's platform, but also ensure that streaming experiences maintain a high level of quality even under heavy demand. The use of advanced encoding techniques and edge delivery models allow Akamai to keep latency low without compromising the reliability or scalability of the stream.

Workflow Components

Akamai's streaming solution is structured around multiple key components that work in harmony to deliver low latency streaming experiences. Whether you opt for their turnkey solution or decide to build a custom workflow, the components provided are designed to handle the entire streaming pipeline from ingestion to final playback.

Media Services Live (MSL)

Akamai's Media Services Live (MSL) acts as a primary ingest point. It allows clients to upload a single live stream, which is then distributed globally via Akamai’s robust Content Delivery Network (CDN). This service is designed for ultra-low latency streaming, particularly when deploying adaptive protocols like LL-DASH or LL-HLS.

Content Delivery Network (CDN) and Edge Computing

A core strength of Akamai lies within its expansive and strategically distributed CDN. With servers placed as close as possible to end-users, the distance data has to travel is minimized, cutting down latency. Additionally, integrated edge computing capabilities allow for local processing such as real-time transcoding and caching, further reducing delays.

Adaptive Media Delivery and Live Transcoding

Clients can take advantage of Akamai's Adaptive Media Delivery solutions which dynamically adjust the quality of the stream based on device capabilities and network conditions. This service not only ensures optimum performance for low latency but also maintains a high quality of experience for the viewer. Live transcoding ensures that various devices, ranging from mobile phones to smart TVs, receive the content in the best possible format.

Building Blocks vs. Out-of-the-Box Solutions

For potential clients, one of the most pertinent questions is whether Akamai provides a completely turnkey solution or if they require the client to build the streaming system using their building blocks. The answer is twofold:

Out-of-the-Box Solution: With products such as Livery—a SaaS solution powered by Akamai's CDN—you can ingest a single stream and have it delivered globally almost immediately. This approach is designed for clients who prefer a ready-to-deploy service with minimal configuration.
Customizable Building Blocks: For clients who require more system control or have specialized use cases, Akamai also provides a suite of modular services. These include APIs, edge workers, customizable delivery accounts, and other components so that you can integrate Akamai’s powerful streaming technologies into an existing infrastructure or build a novel solution from scratch.

This duality in offering means that regardless of your level of technical expertise or the specific requirements of your use case, Akamai has a solution that can be tailored to your needs.

Detailed Comparison of Service Components

Below is a comprehensive table that outlines the key components of Akamai’s low latency streaming solution along with their roles and benefits:

Component	Description
Media Services Live (MSL)	Acts as an origin for live streaming; enables ingesting a single stream that is then globally distributed via the Akamai CDN.
Content Delivery Network (CDN)	A globally distributed network ensuring content is delivered from the nearest server, thus reducing latency and enhancing scalability.
Adaptive Media Delivery	Utilizes protocols such as Low-Latency DASH and Low-Latency HLS to deliver streams with minimal delay, while adapting to network conditions.
Chunked Transfer Encoding (CTE)	Reduces latency through the immediate processing of data chunks rather than waiting for full segment completion.
Edge Computing	Provides localized processing, caching, and real-time transcoding near the end-user to further reduce delay.
Livery SaaS Solution	An out-of-the-box, interactive live streaming solution built on top of Akamai’s infrastructure, ideal for sports, live events, and real-time interactions.

Frequently Asked Questions

What are the primary performance benefits of Akamai’s low latency streaming?

Akamai’s platform minimizes latency by leveraging techniques such as chunked transfer encoding and adaptive bitrate streaming using Low-Latency DASH and HLS. These technologies help achieve latency as low as 1.5 to 6 seconds, while their extensive CDN and edge computing infrastructure ensures rapid content delivery and scalability during peak demands.

Do I need to build my own streaming system or can I opt for a turnkey solution?

Akamai offers both options. You have the ability to use their out-of-the-box solution, such as the Livery SaaS platform, which enables you to ingest a single stream that is then delivered globally with ultra-low latency. Alternatively, if your use case requires a tailored solution, Akamai provides comprehensive building blocks—including Media Services Live, APIs, and edge computing resources—that allow you to build a customized streaming workflow.
