5.1. Colocation Inter-Connectivity (CIC)

5.1.1. Overview

5.1.1.1. Overview

Colocation Inter-Connectivity (called CIC hereafter) is a menu that connects between Logical Network (Data Plane) and Customers’ colocation rack located in designated NTT Com data centers in nearest areas.
CIC enables Customers to utilize both resources of Enterprise Cloud 2.0 and their colocation space in hybrid.

5.1.1.2. Features

CIC has following features:
  • Colocation Inter-Connectivity (called CIC hereafter) is a menu that connects between Logical Network (Data Plane) and Customers’ colocation rack located in designated NTT Com data centers in nearest areas in 1Gbps or 10Gbps bandwidth.

  • CIC provides layer 2 connectivity, which means two sites above are on the same network segment.

  • Customers can either add, delete the connectivity in between Logical Network and their colocation rack through Customer Portal / API. (Customers are required to submit the service order form for initial subscription of this menu.)

../../_images/cic_image.png

It should be noted that CIC has physical connection formed by cables, etc and logical connection formed by physical connection of VLAN. In this article is defined as below:

  • Physical connection, colocation_physical_link (the old parameter name: masterCIC / mCIC)

  • Logical connection, colocation_logical_link (the old parameter name: CIC)

Only physical connection can not communicate with a logical network and customer segment. Always, after you sign up for physical connection, please use the customer portal, etc to create a logical connection.

5.1.2. Available Functions

5.1.2.1. List of Functions

There are mainly two functions in CIC menu:

Function

Overview

Layer 2 Connectivity

CIC connects between Enterprise Cloud 2.0 environment and Customers’ colocation rack located in designated NTT Com data centers in nearest areas.
Please refer to following page for available data centers: https://ecl.ntt.com/en/documents/service-descriptions/rsts/network/cic_dc_list.html

CIC Self-Management

Customers are provided with self-management function to operate CIC via Customer Portal / API.


5.1.2.2. Description of Functions

Layer 2 Connectivity

CIC menu enables Customers to connect their own devices with Enterprise Cloud 2.0 through the specification as follows:

  • Layer 2

  • 1Gbps or 10Gbps Bandwidth

  • Point to Point
Customers can have logical connections with each and every individual Logical Network with VLAN.
  • Up to 24 VLANs are available per mCIC link.

  • The maximum number of available Logical Network is 64, but up to 24 Logical Networks are connectable with CIC.

  • As such, please keep in mind that each maximum number above is different.

One set (one link) consists of two redundant physical wires, which are wired to Customers’ colocation rack.
  • Customers are required to utilize the set of two physical wires at ACT/SBY, as well as to handle the redundancy protocols with their devices.
