Yi Liu - A Senior Network Engineer with expertise in system engineering for current and next generation communications product lines and technologies, customer solution architecture and delivery based on these technologies and implementing methodologies to improve clarity of customer requirements and quality of product. Recognized for keen ability to improve network element designs, increase efficiency and resolve defects at early stage to avoid re-engineering time and cost. Currently the System Architect of Chief Security Office (CSO) of AT&T(2010+), specialized in CALEA/Lawful Intercept solutions for company offered Wireline Broadband Services. Yi Liu holds a Mater’s Degree in Computer Science from University of Bridgeport (2003), a Bachelor’s in Computer Science from University of Chongqing, China (2000).
Abstract: The introduction of IPv4/IPv6 interworking has disrupted the end-to-end lawful intercept model because it results in both IP versions in one communication session. This requires reporting headers of IPv4 and IPv6 in the same CACmII message, which is not allowed by the standards. For reporting CACmII, IASPs are faced with the technical challenge of how to best restore and report the original traffic characteristics of the target under surveillance which are altered and/or hidden by the transition mechanisms.
This presentation provides an impact analysis of two transition mechanisms on the reporting of CACmII. It also identifies possible solutions and open questions for each solution. The goal of the presentation is to stimulate effective brainstorming on the topic.
