Proposal for new NEMO Charter Version: March 22, 2006 Description of Working Group: The NEMO Working Group is concerned with managing the mobility of an entire network, which changes, as a unit, its point of attachment to the Internet and thus its reachability in the topology. The mobile network includes one or more mobile routers (MRs) which connect it to the global Internet. A mobile network is assumed to be a leaf network, i.e. it will not carry transit traffic. However,it could be multihomed, either with a single MR that has multiple attachments to the internet, or by using multiple MRs that attach the mobile network to the Internet. For the basic NEMO support case, none of the nodes behind the MR will be aware of the network's mobility, thus the network's movement is completely transparent to the nodes inside the mobile network. This assumption is made to accomodate nodes inside the network that are not generally aware of mobility. A basic approach for network mobility support is described in the working group's NEMO Basic Support RFC. The WG will take a stepwise approach by standardizing some basic support mechanisms based on the bidirectional tunneling approach, and at the same time study the possible approaches and issues with providing more optimal routing than can be had with (potentially nested) tunneling. However, the WG is not chartered to actually standardize a solution to such route optimization for mobile networks at this point in time. The WG will work on: - Completing editing working group documents that are currently in process, and submit for RFC. - Continue working on Route Optimization and Multihoming, in order to solve the problems that are relevant to NEMO deployments. Furthermore, security considerations for the various approaches will also be considered. - Look into the issues and tradeoffs involved in making the network's movement visible to some mobile network nodes, by making them "NEMO aware". - Address issues with base support RFC and related items, that arise during implementation and deployment. The WG will: - Ensure that solutions will scale and function for the different mobile network configurations, without requiring changes to Correspondent Nodes in the Internet. All solutions will aim at preserving route aggregation within the Internet and will satisfy an acceptable level of security (a thorough survey of new threats and an analysis of their severity will be conducted for any changes introduced to the network). The WG will not: - consider routing issues inside the mobile network. Existing routing protocols (including MANET protocols) can be used to solve these problems. - consider general route optimization, multihoming, or other problems that are not related to the deployment and maintenance of NEMO networks.
