Creanord EchoNEWS: July 2009
Welcome to the July issue of Creanord EchoNEWS. Creanord EchoNEWS aims to keep you informed of the latest developments at Creanord
and in the fields of automated Ethernet service delivery, SLA assurance and Operations, Administration and Maintenance (OAM).
In this issue we will cover one of the key features of our Managed Ethernet Access Devices (NID) called Service Mapping and introduce Samu B�ckman a member of Creanord sales team.
Ethernet service creation and Service Mapping
The Creanord EchoVault's unique combination of service creation & assurance functionality provides highly scalable Ethernet services independent of network topologies or geographic distribution.
To illustrate this, consider a multi-carrier, multi-technology and multi-vendor network bridging two remote customer sites that require a carrier grade E-Line service between them.
As a first step, the service provider provisions an end-to-end circuit by configuring the variety of network elements and partner-carrier interfaces between the two sites. Once the physical circuit
is created, and continuity is established, NIDs are installed at the two service demarcation points, adapting the diverse enterprise IT environments that exist at each end to create a uniform service delivery endpoint.
Service Mapping
The NIDs are then configured through Creanord EchoVault to map an E-Line service between the sites. The service mapping feature allows you to per VLAN tag PUSH with mapped P-bits (based on DSCP or VLAN range).
Service Mapping also allows user selected VLAN ID for tagging, as well as selection of PCP (Priority Code Point) tags (C-VLAN PCP, IP DSCP or IP precedence). Traffic conditioning functions such as per-flow rate limiting,
filtering and traffic shaping are then applied to establish the bandwidth profiles specified in the customers service level agreement.
The Service Mapping Process can be seen as a two-step engine: Classification and Actions.
Classification - Performed at full Wire-speed
Classification identifies traffic flows based on frame characteristics:
- MAC or IP addresses (source or destination, host or network, masks)
- Ethertype
- Customer VLAN ID (C-VLAN)
- Class of Service, PCP (range)
- DSCP value or range
- IP protocol
- TCP/UDP port
Actions - Applied independently or in combination
- S-VLAN tagging : adds a S-VLAN tag ID to the frame (selective push)
- CoS mapping : sets S-VLAN priority: DSCP or PCP, Drop Eligibility
- Bandwidth policing : apply a bandwidth profile based on DSCP or PCP values
- Faster than a switch or router : no added delay or jitter
RFC-2544 and beselining
The automated RFC-2544 testing capabilities are used to perform end-to-end turn up testing and SLA performance baselining, without requiring any additional portable test sets. A report is generated to confirm successful turn-up,
providing evidence to the customer that the service performs as promised. Once the service is in operation, the EchoVaults standards-based Operations, Administration and Maintenance (OAM) functionalities ensure the new link is easily managed from end-to-end.
End-to-End service monitoring
The EchoVaults SLA-Meter provides continuous, end-to-end, in-service monitoring of all critical SLA performance parameters, including one-way delay and jitter, in-service committed throughput verification, circuit availability and packet loss.
The one second accurate bandwidth usage statistics are provided through Traffic-Meter for each site. With the EchoVault Total AEDS Suite operators spot performance issues before they become customer affecting and SLAs are violated.
As operators focus their sights on revenue and services, Creanord EchoVault allows them to overcome networking challenges and provides a carrier grade Ethernet service delivery platform that ensures QoS is built in from day-one onward.
EchoNews Video Tutorial - EchoVault Service Creator policy
The tutorial will cover a new feature of Creanord EchoVault 3.3 called Service Creator.
It allows Standardized Service Catalog driven provisioning of complete Ethernet Service with just few mouse clicks quickly
turning up as many sites as needed. Not to mention the Traffic-Meter per-second bandwidth monitoring! Watch this tutorial now.
