In computer networking, link aggregation is the combining of multiple network connections in parallel by any of several methods. Link aggregation increases total throughput beyond what a single connection could sustain, and provides redundancy where all but one of the physical links may fail without losing connectivity. A link aggregation group (LAG) is the combined collection of physical ports.
In telecommunications, cable Internet access, shortened to cable Internet, is a form of broadband internet access which uses the same infrastructure as cable television. Like digital subscriber line and fiber to the premises services, cable Internet access provides network edge connectivity from the Internet service provider to an end user. It is integrated into the cable television infrastructure analogously to DSL which uses the existing telephone network. Cable TV networks and telecommunications networks are the two predominant forms of residential Internet access. Recently, both have seen increased competition from fiber deployments, wireless, mobile networks and satellite internet access.
In telecommunications, an IP Detail Record (IPDR) provides information about Internet Protocol (IP)-based service usage and other activities that can be used by operations support systems (OSSes) and business support systems (BSSes). The content of the IPDR is determined by the service provider, network/service element vendor, or any other community of users with authority for specifying the particulars of IP-based services in a given context. The IPDR specifications were originally produced by the Internet Protocol Detail Record Organization, Inc.. In 2007, the IPDR.org organization was acquired by the TM Forum, an industry association of more than 900 global members in over 160 countries from across the converging industries of telecom, cable, media and the Internet. The IPDR specifications include requirements for IPDR collection, encoding and transport protocols to exchange IPDR records, the IPDR service specification design guidance, and several sample IPDR Service Definition documents. The IPDR specs are maintained and continue to evolve at the TM Forum Interface Program. The President/COO of IPDR was Kelly Anderson and the technical team lead of IPDR from 2004 until it was Amit Kleinmann of Amdocs.
