Ed Heffernan

Ed Heffernan is a Canadian network engineer and is actively involved in the development of the DOCSIS protocol. The DOCSIS protocol defines inter-communication standards for cable modem and cable modem termination systems (CMTS). Mr. Heffernan is an active and leading participant in the CableLabs standards process and is involved in developing standards within the CableLabs Bandwidth Management Working Group (BMWG).
Mr. Heffernan has developed a unique method for assessing congestion levels in best effort DOCSIS 1.0 systems which is based on both upstream channel utilization as well as upstream channel volume. The methods developed by Mr. Heffernan allow cable operators (Multiple system operator) to generate optimal node combining configurations and to deterministically assess congestion relief scenarios, thus controlling capital and operational expenditure costs.
The work developed by Mr. Heffernan will have significant impact on future broadband deployments and may contribute significantly to the cost effective deployment of broadband systems in North America, Europe and Asia.
In addition to Bandwidth Management involvement, Mr. Heffernan is actively involved in the CableLabs network dimensioning project. Mr. Heffernan is also an active member of the IETF IPCDN working group and is working with the Telemanagement Forum NGOSS initiative, focusing on TNA/SOA areas, and SID and IPDR projects. Mr. Heffernan is currently working as Open source software (OSS) Architect for Rogers Cable Inc., a Canadian telecom, video and internet service provider.
He lives in Toronto, Canada.
