Topology Dataset Requests

Data providers face a unique challenge in that requiring users to apply for data access discourages data use because some users find the application process too onerous and do not pursue data access. Yet significant resources are required to collect, curate, document, and serve scientific datasets to the research community.

To encourage support for data collection activities while not prohibiting access for users without resources, CAIDA provides access registered academic, government, and non-profit researchers and CAIDA members. We ask for-profit companies to sponsor CAIDA in order to gain access to these restricted datasets. All data access is subject to Acceptable Use Policies (AUP) designed to protect the privacy of monitored communications, ensure security of network infrastructure, and comply with the terms of our agreements with data providers.

To gain access to data, prospective users fill out a request form with their contact information and intended usage. Requests are validated and accounts activated. Most qualified researchers receive data access within two business days.
