Key Features Implemented

1. Modular PD Router (`pd_router.rs`)

Clean separation from existing router logic
Manages prefill and decode worker pools independently
Supports multiple selection policies:
- Random: Simple random selection
- PowerOfTwo: Load-aware selection with background monitoring
- CacheAware: Designed, implementation pending (Phase 3)

2. Typed Request Handling (`pd_types.rs`)

GenerateReqInput and ChatReqInput structs with Bootstrap trait
Handles both single and batch requests via SingleOrBatch<T> enum
Type-safe bootstrap information injection

3. Bootstrap Injection

// Automatically injects routing metadata into requests
request.add_bootstrap_info(&prefill_server)?;
// Results in:
// - bootstrap_host: Prefill server hostname
// - bootstrap_port: Bootstrap communication port  
// - bootstrap_room: Unique room ID for prefill-decode coordination

4. Concurrent Load Monitoring (PowerOfTwo Policy)

// Background task monitors all worker loads concurrently
async fn monitor_worker_loads(worker_urls: Vec<String>, ...) {
    loop {
        // Fetch loads from all workers in parallel using tokio
        let futures: Vec<_> = worker_urls.iter()
            .map(|url| async {
                get_worker_load(&client, url).await
            })
            .collect();
        
        let results = futures_util::future::join_all(futures).await;
        
        // Broadcast updates via tokio watch channel
        tx.send(loads);
        tokio::time::sleep(interval).await;
    }
}

Key benefits of concurrent load monitoring:

Fetches load from all workers in parallel (not sequential)
Updates broadcasted via tokio::sync::watch channel
Zero overhead for non-PowerOfTwo policies

5. Logprob Merging (Critical for correctness)

Non-streaming: Merges input_token_logprobs from prefill response
Streaming: Buffers first prefill chunk and merges with each decode chunk
Maintains SSE format compatibility

6. Fix Payload Support

Increased default limit to 256MB (from 4MB)
Supports large batch requests
Configurable via constructor

Performance Results

Benchmark: Llama-3.1-8B-Instruct
Configuration:
Batch size: 8
Input length: 4096 tokens

Usage

Python API

from sglang_router import Router, PolicyType

# Option 1: Using dedicated PD constructor
router = Router.new_pd(
    prefill_urls=[
        ("http://prefill1:8080", 9000),  # (url, bootstrap_port)
        ("http://prefill2:8080", 9001),
    ],
    decode_urls=[
        "http://decode1:8080",
        "http://decode2:8080",
    ],
    policy="po2",  # or "random", "cache_aware"
    host="0.0.0.0",
    port=8080
)

# Option 2: Using main constructor
router = Router(
    worker_urls=[],  # Empty for PD mode

Summary of Changes

Hello @slin1237, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request integrates the Prefill-Decode Load Balancer (PDLB) functionality into the SGLang Router, enabling disaggregated routing for prefill and decode stages of LLM inference. It introduces a new modular PD router, typed request handling with automatic bootstrap injection, and implements Random and Power-of-Two load balancing policies for PD mode. The changes are designed to be backward compatible with existing single-worker routing and lay the groundwork for future cache-aware PD routing.

Highlights

Prefill-Decode Disaggregated Routing: Adds a new PrefillDecode policy to the router, allowing requests to be routed to separate pools of prefill and decode workers for improved efficiency.
Modular PD Router Implementation: Introduces a dedicated PDRouter module in Rust (pd_router.rs) to encapsulate the logic for managing prefill and decode workers, selecting pairs, executing dual dispatch, and handling PD-specific concerns like logprob merging.
Multiple PD Selection Policies: Implements "Random" and "Power-of-Two" load balancing policies specifically for selecting prefill-decode worker pairs. "Cache-Aware" policy is designed but marked as pending implementation (Phase 3).
Typed Request Handling and Bootstrap Injection: Defines new Rust structs (GenerateReqInput, ChatReqInput) and a Bootstrap trait (pd_types.rs) to handle incoming requests in a type-safe manner and automatically inject necessary routing metadata (bootstrap host, port, room ID) for prefill-decode coordination.
Concurrent Load Monitoring: Adds a background task for the Power-of-Two policy to concurrently fetch load information from all workers using tokio::sync::watch for efficient updates.
Logprob Merging: Implements logic within the PDRouter to correctly merge input_token_logprobs from the prefill response with the decode response, supporting both streaming and non-streaming formats, which is critical for correctness in disaggregated mode.
Increased Default Payload Size: The default maximum request payload size is increased from 4MB to 256MB in the Python launch script and Rust library to accommodate large batch requests common in benchmarking.
Python API and CLI Updates: Adds a dedicated Router.new_pd() class method and new command-line arguments (--policy prefill_decode, --prefill-urls, --decode-urls, --pd-policy) to configure and launch the router in Prefill-Decode mode.

Code Review

This pull request introduces a significant and well-architected Prefill-Decode Load Balancer (PDLB) feature into the SGLang Router. Key changes include:

New PD-specific Python configurations in launch_router.py for prefill/decode URLs and policies, along with an increased default max_payload_size.
A Python Router.new_pd classmethod for creating PD-configured routers.
Core Rust PD logic in new pd_router.rs and pd_types.rs files, defining PDRouter, EngineInfo, PDSelectionPolicy, typed request structs (GenerateReqInput, ChatReqInput), and the Bootstrap trait for metadata injection.
Dual dispatch mechanism in PDRouter to concurrently send requests to prefill and decode servers.
Logprob merging for both streaming and non-streaming responses when return_logprob is enabled.
Background load monitoring for the PowerOfTwo selection policy.
Updates to the main Rust Router to integrate PD mode, including a new PrefillDecode variant and corresponding PolicyConfig.
Refinement of server endpoint handlers in server.rs to use typed requests for PD mode.
A comprehensive new test suite in test_pd_routing.rs covering various aspects of PD functionality.

The changes are generally clear, modular, and address the core requirements for disaggregated inference. The introduction of typed requests for PD mode is a strong design choice. Some minor areas for consideration include the PDRouterWrapper in Python and ensuring robust hostname parsing if those hostnames are used in sensitive contexts. The test suite is thorough and provides good coverage for the new features.

Overall, this is a high-quality contribution that significantly enhances the router's capabilities.

Entry point handling between PD and standard router is a bit weird at the moment, one is typed request and another is byte.
Thus the code itself is also weird. This is temporary, eventually we will merge them into typed and unified the request handling such as parsing, validation etc.
the PR is already enormous, would like to focus on existing effort and start new planning for merging request handling (byte vs typed)
furthermore, existing PD request also requires bootstrapping port handling, which is slightly different than standard OAI requests

Seem not necessary to skip these 2 headers here since the req is not altered and the .json() does not called?

Maybe we can wrap the PD-disagg router and non-disagg router into one, instead of setting pd-router a subfiled of a normal router, then we can avoid a lot of unreachable code and asserts.

hnyls2002 · 2025-06-17T16:17:51Z

@Simon-Li LGTM left some comments which can be solved later. The overall hierarchy for the router/server ends needs to be reorganized, so that we can reuse some common codes between two different dispatch modes (singular dispatch and dual dispatch).

@ByronHsu Can you take a look? As the PD parts for this PR are still dead code, if this PR doesn't break the original sgl-router, I think we can merge it first.

For now we only support PO2 in pd-disagg mode, actually PO2 is also fitable for non-diagg mode, serving as a better strategy than random.

yes, we can should add this to no-diagg mode
