We've added JavaScript-native RPC to Cloudflare Workers
We've added JavaScript-native RPC to Cloudflare Workers04/05/2024 Cloudflare Workers now features a built-in RPC (Remote Procedure Call) system enabling seamless Worker-to-Worker and Worker-to-Durable Object communication, with almost no boilerplate. You just define a class: export class MyService extends WorkerEntrypoint { sum(a, b) { return a + b; } } And then you call it: let three = await env.
How to receive a million packets per second
Last week during a casual conversation I overheard a colleague saying: "The Linux network stack is slow! You can't expect it to do more than 50 thousand packets per second per core!" That got me thinking. While I agree that 50kpps per core is probably the limit for any practical application, what is the Linux networking stack capable of? Let's rephrase that to make it more fun: On Linux, how hard

CloudflareのサーバーはもうIPを所有していません。では、どのようにインターネットに接続しているのでしょうか？
データセンター内のIP共有サーバー間でIPを共有するという考え方は新しいものではありません。ルーター上のSource-NATで実現してきた方法です。残念なことに、必要なエグレスIPの数が非常に多く、また運用のサイズも大きいため、ルーターレベルでステートフルファイアウォールまたはNATに依存できません。また、当社は共有状態を好まないので、NATの分散インストールは避けたいところです。 代わりに選択したのは、ポート範囲によるサーバー間におけるエグレスIPの分割です。特定のエグレスIP に対して、各サーバーは使用可能な送信元ポートのごく一部（ポートスライス）を所有します。 インターネットからリターンパケットが届くと、それを正しいマシンに戻すルーティングをしなければなりません。このタスクのために、L4 XDPベースのロードバランサーである "Unimog "をカスタマイズしました。当社のL4 XD
