摘要： A system and method for transmitting and bundling network packets is provided. The incoming network packet size is determined and if the remote buffer space is sufficient to hold the network packet it is transmitted to the destination port. If the remote buffer space is not enough to hold the network packet it is discarded. The system includes an arbitration module that receives remote buffer space information and transmits the network packet if the remote buffer space has enough space to hold the packet. The arbitration module also determines if a second network packet is from a same source port having a same source virtual lane, and has the same destination virtual lane (bundling conditions). If the second network packet meets the bundling conditions, then it is transmitted after the first network packet, even if other packets were received before the second network packet.
摘要翻译：提供了一种用于发送和捆绑网络数据包的系统和方法。确定进入的网络分组大小，并且如果远程缓冲区空间足以容纳网络分组，则将其发送到目的地端口。如果远程缓冲区空间不足以容纳网络数据包，则会被丢弃。该系统包括仲裁模块，其接收远程缓冲区空间信息，并且如果远程缓冲空间具有足够的空间来容纳该数据包，则发送该网络分组。仲裁模块还确定第二网络分组是否来自具有相同源虚拟通道的相同源端口，并且具有相同的目的地虚拟通道（捆绑条件）。如果第二网络分组满足捆绑条件，则即使在第二网络分组之前接收到其他分组，则在第一网络分组之后发送。

摘要： A method and system for credit recovery of lost frames and R_RDYs in an in-line credit extender is provided. The method includes, comparing received frame count and a programmable counter value when BB_SCs are received; loading the difference between the frame count and the programmed counter value into a buffer and to a first counter that counts each frame that is transmitted; and sending BB-SCs to the local device if there is a match between the first counter value and a second programmable counter value. The method also includes, counting received R_RDYs, wherein a first counter counts the received R_RDYs; setting a flag when a BB_SCr is received; and transmitting BB-SCr when the first counter value is zero and the flag is set. Also, R_RDYs received after BB_SCrs are counted by a second counter and transmitted when the second counter value is non-zero.
