WISPiab specifications

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

Discussion of business models: WISPiab_business_models

High level architecture

Our currently suggested architecture splits the WISPiab hardware package into two components plus an option:

1. Front Access Node
2. Back end server (with or without screen, depending on existing ...)
3. (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

Shared functionality

• 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

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

Mail

• 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

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
