ITRG Mission:
ITRG Techniques / Competencies:
ITRG Current Focus Areas:The group's programmatic focus is upon Trustworthy Networks, where we work to establish the technical basis necessary to improve the security, resilience and performance of the communication infrastructures that underly our network-centric society. Our research cultivates trust in current and emerging network technologies by developing and applying innovative measurement techniques, improving the quality and timeliness of consensus standards, and providing tools and guidance necessary to expedite adoption of advanced network technologies. ITL collaborates directly with leading industry research (Internet Research Task Force), standards (Internet Engineering Task Force) and network operations (North American Network Operators Group) groups to leverage NIST contributions and foster the design, standardization and commercial deployment of solutions to systemic vulnerabilities and robustness issues in the core Internet technologies. Major technical areas within this program include:

NIST RPKI Deployment MonitorAugust 15, 2012 - April 26, 2021 The NIST RPKI Monitor is a test and measurement tool designed to monitor the dynamics of the global Resource Public Key Infrastructure (RPKI) and the impact of Awards and RecognitionITRG Quick LinksITRG Additional InformationWhat is responsible for the Internet domain name system and the allocation of IP addresses?ICANN is a public-private partnership that is responsible for the following functions related to internet names and numbers: Allocation of IP address space. ICANN manages the distribution and allocation of IP version 4 and IP version 6 network addresses through five regional internet registries.
Which of the following was created for the transfer of hypertext documents across the Internet?Hypertext Transfer Protocol (HTTP) is a method for encoding and transporting information between a client (such as a web browser) and a web server. HTTP is the primary protocol for transmission of information across the Internet.
Which of the following is an example of instant messaging service?Some examples of widely used IM services are Google Talk (commonly called Google Chat), Slack, Jabber, Spark, and many more. The advantages of IM are that messages are sent and received instantly in real time and responses are organized in a “conversation” format that supports two-way communication.
Which protocol is used to transmit email over the Internet?The Simple Mail Transfer Protocol (SMTP) is used to deliver e-mail messages over the Internet. This protocol is used by most e-mail clients to deliver messages to the server, and is also used by servers to forward messages to their final destination.
