Abstract
The present invention relates to highly available sequence number generation with minimal latency. The present invention involves establishing a primary and secondary sequence number generators. A sequence number request is forwarded to the primary generator. The primary generator determines the next sequence number and forwards the response to the secondary generator. The secondary generator stores the value and forwards the value to the originating entity. Accordingly, the configuration avoids single point failure and is robust against malfunction.
