Regex Matching

Last year we introduced the ATLAS-2000 Service Node (ASN) and while it supports all Accolade value added features, one of the more popular ones for this platform is regex or regular expression matching. Most packet processing operates at the lower levels of the OSI model; specifically layers 2, 3 and 4. However, with specialized code Accolade can also match alphanumeric patterns at the application layer. This is particularly useful if someone wants to examine application-level data (think emails or web pages) for certain key phrases or patterns.

Regex manipulation is quite common in high level programming or scripting languages such as Perl. With regex these programming languages use string searching algorithms for “find” or “find and replace” operations on strings. For example, you might do a search on an email (or many emails) to see how many times a specific person’s name was referenced.

Regex matching is a powerful tool for network monitoring, security and other use cases. If you couple the processing power of an ATLAS-2000 with a strong regex engine the possibilities are vast.
