9145 Application Overview

Providing a manageable demarcation point for Ethernet Services is not enough. For successful service deployment and high customer, satisfaction in today's demanding business environment, diagnostic, network performance and subscriber network/core network interoperability and compatibility is a must. The 9145 provides all these services and more in a compact customer premises Network Interface Device. Using a Canoga Perkins L351 or L357 Ethernet Service Unit at the Central Office or POP Site, management access to the 9145 NID is transparent and in the background outside of subscriber's bandwidth. With full access to the 9145's advanced diagnostics, traffic statistics, network performance/SLA assurance reporting, frame type filtering, jumbo frame support and advanced VLAN tagging and management capabilities, not only is network compatibility and interoperability assured, but the ability to anticipate network problems can be identified and corrected before subscriber's traffic is negatively impacted. Network and User Interfaces on the 9145 are modular and hot swappable for flexibility in deployments. A variety of optical interfaces is available including Single Fiber and CWDM.

In-band SNMP and SideBand can be used exclusively or concurrently, matching the Service Providers operations requirements and preferences. This allows best matching of technique for surveillance, routine diagnostics or special testing for TLS (shared backbone/VPN services). SideBand ensures the customer has full wireline bandwidth at all times while still providing full management access for the Service Provider for LES (private line type services). Mid-point management access allow easy and quick identification of problems to the circuit segment and cause,This maximizes service availability.

Application

9145 VLAN Tagging and QOS Functions

A common Ethernet Service is Transparent LAN Services (TLS), a shared backbone VPN service. Subscribers only sees their locations on the network, no one else. This service is the Ethernet analog of the traditional Frame Relay Service, but simpler for the subscriber to implement. A popular method of implementing the VPN within the Service Provider network is by the use of 802.11g VLANs.

Trusting the subscriber to correctly tag traffic 100% of the time is risky, problematic, and usually leads to service problems. Canoga Perkins’ line of Network Interface Devices and Metro Ethernet Switches are optimized for the subscriber interface and has powerful VLAN Tagging and Translation functions. An additional capability is the capability to set a priority indicator in the VLAN Tag header.

The 9145 Network

Interface Device performs four VLAN related functions:

• Tagging untagged subscriber frames
• Translating a subscriber tagged frame to a different tag
• Adding an outer tag to a subscriber tagged frame
• Setting P-Bit values

Referring to the above diagram, the 9145 tags untagged subscriber traffic with VLAN ID D. Standard 1420 Byte frames or Jumbo Frames up to 9Kbytes are supported and transparently tagged. Concurrently, subscriber VLAN tagged frames (VLAN ID A) to get translated to a different VLAN ID, E in this example. VLAN ID B remains unchanged while VLAN C frames received an outer tag of VLAN ID F (VLAN Stacking). The 9145 tags the entire frame irrespective of the number of tags the frame already possesses. Quality Of Service (QOS) or (P-Bit) handling is configurable for a specific value or replication of the original frame’s value.The flexibility of setting VLAN parameters allow you to condition subscriber traffic in a format optimized for core network transport without unnecessary configurations/changes to the core network or subscriber’s network.
