Quarterly AT&T Ecosystem Port to Circuit Mapping
By SEDA AI
Overview
This report outlines the relationships and workflows between circuit and port IDs, including service types, bandwidth allocation, and functional roles. The details provide a clear understanding of the ecosystem structure and its operational interdependencies.
Interconnection of Services
ADI Services
- Serve as the internet backbone for MPLS or SD-WAN networks.
- Route traffic from MPLS circuits and Ethernet services via high-speed ports for external communication.
MPLS Circuits
- Aggregate traffic from multiple sites, including Ethernet Basic Services.
- Utilize ADI connections (via Port IDs) to send traffic to cloud services or internet destinations.
Ethernet Basic Services
- Connect branch locations to MPLS backbone or ADI for cost-effective solutions.
- Act as 'last-mile' connections for small offices or remote sites.
Port-to-Circuit Mapping
- Port xxxxxxxx: Handles 100 Mbps traffic from MPLS and Ethernet branches.
- Port xxxxxxxx: Manages high-bandwidth (1 Gbps) traffic for major sites or data centers.
Example Traffic Flow
Branch Site
- Sends 10 Mbps traffic to MPLS Circuit xxxxx.xxxxxx.
- MPLS routes traffic to another branch location or sends non-critical traffic to the internet via Port xxxxxxxx.
Large Data Center
- Aggregates traffic from multiple MPLS nodes.
- Routes internet-bound traffic via Port xxxxxxxx for high-speed access.
Detailed Examples by Location
Small Branch Offices
- Connect to MPLS backbone via Ethernet Basic Services.
- Route traffic to regional hubs.
Regional Hubs
- Aggregate branch traffic and prioritize MPLS for high-priority data.
- Use ADI for cloud access.
Central Data Centers
- Support centralized applications and serve as the MPLS core.
- Provide internet redundancy via high-bandwidth ADI.
Large Corporate Locations
- Manage enterprise-wide backups and inter-site traffic.
- Host cloud services via MPLS Flex Ethernet.
Integrated Workflow
1. Small Branch to Regional Hub
- Routes VoIP calls and POS data to the hub via MPLS.
- Aggregated traffic sent to corporate data center for processing.
2. Regional Hub to Data Center
- Processes intermediate data locally.
- High-priority traffic sent to corporate data centers via high-bandwidth MPLS circuits.
3. Data Center to Cloud
- Uses high-speed ADI for SaaS and cloud services.
- Handles backups and analytics data uploads.
4. Failover and Redundancy
- Reroutes traffic via ADI in case of MPLS failure.
- Branch offices access cloud services directly via ADI as a fallback.
