NNI

Recently I was asked to explain what an NNI was and I thought that this would make for a great topic for my blog

NNI - Network Network Interface. I will be explaining NNI in a GMPLS (Global MPLS) scenario.

The EMEA MPLS Provider is offering services but the Asia locations have to pay for expensive connectivity options over long distances. This increases latency and costs even when the Asia customers want to communicate with other Asia customers such as Hong Kong and Singapore.

The EMEA MPLS Provider partners with a Third Party MPLS Provider which provides a local MPLS network and has local presence in each center reducing the overall costs. This provides low latency connectivity options within the region. The EMEA MPLS Provider and the Third Party MPLS Provider create an NNI connection with each other and form a GMPLS network.

 

MMR

MMR (meet me room) - is a location within a collocation facility or Tel-co Hotel where telecommunications (carriers) and enterprise customers can connect there physical connectivity to one another. This allows them to eliminate the cost of local loop fees and gives them the ability to exchange data between one another. This is the room where the cross-connect happens. Some of the services offered include remote hands (smart hands), power, cooling, and cross-connects.

Carrier Technology

Carrier Technology - I thought I would put a cheat sheet together for some of the carrier technologies used, this is not a comprehensive list but it is a nice start to one. Please feel free to add any technologies to the comment section below.

OC = Optical Carrier - specification for transmission bandwidth using digital signals carried on SONET (Synchronous Optical Networking)
DS = Digital Signal T-Carrier - is a standard in telecommunications in North America and Japan
E = E -carrier - is a standard in telecommunications in Europe and widely used outside of NA and Japan, improves on T-Carrier used in NA and Japan
HSCSD = High-Speed Circuit-Switched Data - faster than GSM  - used in mobile networks
GSM = Global System for Mobile - Worlds most popular standard for mobile networks
EDGE = Enhanced Data rates for GSM Evolution - is considered pre 3G technology - used in mobile networks
UMTS = Universal Mobile Telecommunications System - 3G technology - used in mobile networks
EV-DO =  Evolution-Data Optimized or Evolution-Data only - uses CDMA and TDMA
DSL = Digital Subscriber Line
