信令协议主要在软件中实现有两个原因：协议的复杂性和对灵活性的要求。虽然这是在软件中实现信令协议的两个很好的理由，但付出的代价是性能。信令协议的软件实现很少能够处理超过1000个呼叫/秒。每个交换机对应的呼叫设置延迟以毫秒为单位。为了提高高速网络的性能，我们在可重构FPGA硬件中实现了RSVP-TE信令协议。我们的实现证明了与软件实现相比提速100倍和潜在的1000倍的可行性。这项工作的影响是非常深远的，因为它允许面向连接的网络支持各种新应用程序，甚至是那些呼叫保持时间较短的应用程序。
Signaling protocols are primarily implemented in software for two reasons: protocol complexity and the requirement for flexibility. While these are two good reasons for implementing signaling protocols in software, the price paid is in performance. Software implementations of signaling protocols are rarely capable of handling over 1000 calls/sec. Corresponding call setup delays per switch are in the order of milliseconds. To improve performance for high-speed networks, we implemented RSVP-TE signaling protocol in reconfigurable FPGA hardware. Our implementation demonstrates the feasibility of 100x and potentially 1000x speed-up vis-a-vis software implementation. The impact of this work can be quite far-reaching by allowing connection-oriented networks to support a variety of new applications, even those with short call holding times.
