Question 2/2 - Routing and interworking plan for fixed and mobile networks
(Continuation of Q.2/2)
With the rapid evolution of network technology, it is increasingly important to ensure that integration of voice, data, video, and multimedia services on such networks can route and interwork with networks based on other technologies, particularly TDM-based PSTN networks, ISDN, frame relay, ATM, and mobile network technologies. Routing methods are currently being extended to converged network services integrated on a shared network. Existing routing methods are not adequate to address all the QoS and performance issues that arise with the extended applications.
Items like Internet of things, cloud computing, and so on will have to be studied regarding possible gaps in the routing principles to interconnect and interoperate the different kinds of identifiers and related services so far identified.
The Question will deal with the issues detailed under Tasks below.
Project number
Topic and rationale
Target completion date
Maintenance of existing E-series Recommendations
Rationale: It is essential to provide required evolution in existing recommendations (E.170 – E.179; E.350 – E.399).
Routing for new network applications and technologies
Rationale: Network technologies are being widely extended to include voice, data, video, multimedia, and other services integrated within the NGN. This project will extend the work on the E-Series of Recommendations to identify and recommend routing needs within next generation networks, including Internet of Things and cloud computing.
Dynamic routing for mobile networks
Rationale: This project will consider networks where topologies are in motion rather than fixed. It is expected that the change in perspective will lead to new routing architectures, protocols, and methods. This project will provide new recommendations on routing extensions arising from these mobile technologies.
Routing congestion control
Rationale: State-dependent routing methods that flood link-state and topology information throughout the network are subject to overload and congestive collapse. This project will provide routing congestion control methods and Recommendations to address these issues.
Availability of routing information
Rationale: It was noted that the lack of information on the overall call routes from the originating entity up to the terminating entity may be a contributing factor of misuse (ref. WTSA-08 Resolution 61 on International telecommunication numbering resource misappropriation). This project will investigate how to make the routing information available for calls based on international telecommunication numbering, naming, addressing and identification resources (ref. WTSA-08 Resolution 20), noting that there may be national issues impacting this, to the terminating operator to assist in identifying possible instances of fraud, misuse, and security related issues.
Other projects
Rationale: New and/or modified projects will be introduced as needed, as has always been the experience.
Within Study Group 2
All questions dealing with the definition and characteristics of telecommunication services for which routing technologies will be utilized, and to also include questions focusing on a) numbering and addressing plans (e.g. Q.1/2); b) network management and performance (e.g. Q.5/2).
