Introduction
The following is our work copy of a specification / feature wish list for the WISP-in-a-box product.
It is meant to be commented and refined.
Business Models / Use cases
It is essential that the specifications be based on business model needs and real life use cases.
While these need to be refined and studied further (e.g. in the Wireless Africa II project),
we list some main examples and key words here.
Basic access models: Centralized and Mesh
The entrepreneur wants to offer both centralized (aka infrastructure, hot spot, access point) and mesh models
==> We need to implement both Access Point Management and Mesh protocols
Networks models in detail
In particular, we need to take into account the following 3 network models, and the hybrid models between them.
In the following pictures,
- red stands for business / entrepreneur owned and operated nodes,
- blue stands for clients / users.
The line between the two may be transparent.
Centralized model
- The business/entrepreneur acts as a central access point.
- The central business/entrepreneur node supplies an internet uplink (optional).
- Clients connect to this central point, e.g. with PCs, laptops, client nodes or VoIP phones.
Inframesh model
- The business/entrepreneur operates an infrastructure mesh.
- The business/entrepreneur node supplies internet uplink(s) at one or more of these nodes (optional).
- Clients connect one or more of these nodes, as clients, e.g. with PCs, laptops, client nodes or VoIP phones.
Full mesh model
- The business/entrepreneur operates one or many mesh nodes.
- The business/entrepreneur node supplies internet uplink(s) at one or more of these nodes (optional).
- Clients fully particpate in that mesh, typically on dedicated node hardware, less likely with PC/laptop, and even less with VoIP phones. Clients may supply internet uplinks (optional).
Especially in this model, the line between business and client operated nodes might become transparent.
Network Management
The entrepreneur needs to be able to monitor, manage, troubleshoot the network
==> We need network management SW plus interfaces, e.g. Nagios, Cactus, Webmin, ...
Voice Services
The entrepreneur wants to offerVoice services
==> We need to implement Asterisk, OpenSER or similar, plus additional management tools for these, if idnetified as needed
Billing
The entrepreneur wants to offer a variety of billing options, e.g. monthly subscription, time/voucher (airtime) based, free access
==> We need to implement billing and accomodate the various models on the box, in parallel (e.g. parallel free and closed segments, etc)
High level architecture
Our currently suggested architecture splits the WISPiab hardware package into two components plus an option:
- Front Access Node
- Back end server (with or without screen, depending on existing ...)
- (Sub)Laptop as GUI admin (optional)
This seems appropriate based on the analysis of the SW specs in detail.
However, if test implementations seem to suggest reuniting the two tiers on one box, this is an open option, which might bring manageability benefits.
Software Specification / Feature list for the WISP-in-a-box product
- All configuration etc to be accessible via browser based GUI
- ssh access
- Routing Protocols
- OLSR
- b.a.t.m.a.n.
Front access node
- CoovaAP
- Authentication potentially with 2 options
- Against itself / on acces node
- Against back end server Radius
- Authentication potentially with 2 options
CoovaAP will bring most of the following mandatory features for the front access node.
- OpenSER
Back end server
- apache
- php
- mediawiki
- mysql
- ispconfig
- webmin?
- DNS server (DDNS, DynDNS)
- Proxy / Cache
- Squid
- Postfix / Courier
- Webmail: squirrelmail
- gmail syncing desirable
- Google server local? (--> talk to gmail, Kobus)
- Spam/Virus control
- amavis
- spamassassin
Network management
- Nagios
- Cacti
- Statistics
- awstats or similar
Auth, Access, Security, Billing
- Radius
- FreeRadius
- OpenLDAP
- OpenID
- OpenVPN
- GnuPG
QoS
- QoS - details of this not clear yet - what layer? what tools?
- iproute2
- MasterShaper?
- Wondershaper
Storage, FS
- NAS – iSCSI
- File servers
- SMB
- NFS
- rsyncing cron'd
- Redundancy - to be psecified in more detail
- Would liek to build distributed storage - “graded distributed system”
Voice over IP
- Asterisk
- OpenSER
- billing integration
- a2billing
Miscellaneous
- Local Library of SW
- Documentation
- Integrated Skilling / Education
- patch management
- IpCOP
- wikipedia local copy
- Content filtering ? - discussion!
- Virtualization (XenSource)
- to be discussed - not deemed mandatory
Hardware Specification / Feature list for the WISP-in-a-box product
To be spec'ed after completion of SW specs.
Minimum requirements
General requirements for all elements
- Input: 12 V_dc
- Fanless
- Low power (< 8 W)
Front access node
Network interfaces 2 minimum, maybe more
Back end server
external switch
