Nextelco:CNOC

CNOC is part of the Nextelco:Technology has two functionalities 1) ASN gateway for WiMAX 802.16e (not yet used) 2) Measurement and management of IP traffic, and Database-oriented access

Database-oriented access

The CNOC has an inbuilt database, consisting of

• username/passwd, amount, time, access rate

Example:

• josef/password, 1 GByte, 1 month, 10 Mbit/s

documentation: ??

Operation and Implementation

From Raviv Zeev <RavivZ@runcom.co.il>:

As indicated many times before you should have a test PC located in Norway that will allow you to test the user scenarios without involving the Satellite link. Btw, CNOC doesn't provide any IP addresses. The IP are given to the users by your router.

General description of Runcom Compact Network Operation Center

The Runcom CNOC device is a cost effective system that provides a full network solution within one box for wireless cells. It is based on Runcom distributed ASN (Access Service Network) service gateway hardware and provides a feature rich, cost effective and modular solution specifically for small 802.16e (WiMAX) wireless networks. The Compact NOC includes ASN gateway functionality, IP allocation service, CPE (Customer-premises equipment or customer-provided equipment) authentication capabilities and WiMAX service configuration to allow full network operation without additional NOC entities (servers). These are the main features:

• ASN gateway
• IP allocation
• Internal DHCP
  • DHCP relay
  • Fixed IP
  • IP pool
• CPE authentication
• WiMAX service

The next Figure shows which are the interfaces of the CNOC:

Among others, these are the basic CNOC features:

• Scalability, from 100 to 2000 subscribers
• Smooth migration
• Authentication, internal authentication mechanisms both for CPE and end users.
  • NULL authentication
  • EAP-XXX (using external AAA system [RADIUS])
  • Key context cashing ¿?
  • MAC/IP authentication
  • WEB authentication
  • User behind CPE authentication
  • User/Device level authentication
  • AAA proxy
• Configuration of different service plans
• DHCP to allocate IP addresses both for CPEs and end users
• ACL to enforce network-based access lists on individual end-user traffic
• WiMAX 16D cluster support
• Multi user behind CPEs, each user being handled separately including authentication and servicing
  • Users can be identified by:
    • CPE MAC address
    • IP address
    • Username
    • MAC address of the station behind CPE
  • Each user can be configured with service group which defines:
    • QoS
    • IP
    • other parameters
• Enable subscribers to change their service plan on the fly
• Walled garden or closed platform, where administrator can have control over applications, content and media and restrict convenient access to non-approved applications or content. Here dynamic access lists are used.
• Dynamic bandwidth control for each user
• Application awareness, where network administrator can differentiate service profiles based on the applications that are used by each user at certain point in time.
• Accounting
  • Start, stop and interim
  • Accurate time based
  • Service flow statistics (when using external AAA system)
• Pre-paid, simultaneously quota of
  • Data
  • Time
  • Application

Additionally it offers the following network characteristics:

• 802.1q VLANs
• QinQ, 802.1ad allows multiple VLAN tags to be inserted into a single frame, an essential capability for implementing Metro Ethernet (MAN) network topologies.
• Several routing protocols
  • RIP
  • OSPFv2
  • Source based routing
  • Application based routing
• Several tunneling protocols
  • Generic Routing Encapsulation (GRE)
  • IPinIP, IP tunneling protocol
  • L2tp, Layer 2 tunneling protocol
• Multicast
• MMS adjustment
• VRRP, Virtual Router Redundancy Protocol
• AAA redundancy
• DHCP redundancy
• Dynamic Packet coloring (upstream/downstream)

Configuration

The command-line interface has four system management menus:

• Administration
• Configuration
• Display
• Diagnostics
