OpenNOP - 開放式網絡優化平臺

利用OpenNOP實現開放的網絡加速。靈活的部署選項；網狀網絡技術支持；無隧道實現；基于Linux的應用程序。它具有以下特性：

• Automatically discovers numerically highest IP address to use as the accelerator ID. Excluding the loopback IP address 127.0.0.1. Duplicate accelerator ID’s would prevent the accelerator auto detection logic from functioning.
• Determines the number of cores in the system and creates N-1 worker threads for processing IP packets. If there is only one core a single worker thread is created.
• All packets for a particular session are assigned to the same worker thread. The packets for that session get processed in the order they are received to maintain packet delivery sequence.
• Only packets of TCP sessions with modified MSS will be processed. The modified MSS provides space for injection of custom TCP options used by the accelerators.
• Discovers other network accelerators by detecting custom TCP options the accelerators add to IP packets.
• Detects when remote network accelerator fails or is shutdown and stops accelerating packets.
• Optimizes TCP segment payload using LZ compression.
• Pads SEQ numbers of optimized TCP payloads so they will not be processed by the destination. They must be de-optimized by the destination network accelerator to fix SEQ number.
• Checks for dead sessions by sending keep-alive messages to inactive clients/servers and removes dead sessions the session table.
• Heartbeat between user space daemon and kernel module so kernel module can switch to bypass mode.
