Alcatel-Lucent ES4 Series - Manual (Page 2)

Alcatel-Lucent ISA-ES1 and ES4 Series | Data Sheet
The ISA-ES series meets the Ethernet
technology needs of Tier-1 and Tier-2
service providers, service-provider
carriers, multisystem operators or mobile
service operators (MSOs), cable operators,
power utilities and government
institutions.
Each ISA-ES module has a configurable
IP address and User Datagram Protocol
(UDP) port for the network management
to manage Ethernet services, including
implementation, alarms retrieval and
QoS Performance Monitoring (PM).
ISA ES1 and ES4 circuit-pack
overview
• Electrical and optical FE/GigE
interfaces, with Small Form
Factor Pluggable (SFP) optics
• A comprehensive set of:
¬ Ethernet switching features
(802.1d/Q/ad)
¬ Resiliency features: xSTP, Link
Aggregation Group (LAG), link
capacity adjustment scheme
(LCAS) and SDH-based protection
¬ QoS features: for example,
policing, priority marking,
per class queuing and WDRR
¬ Ethernet PM counters
¬ Ethernet Operations, Administration
and Maintenance (OA&M) suite
(ITU-T Y.1731/IEEE 802.1ag)
• EoS adaptation suite, using generic
framing procedure (GFP) (G.7041),
link access procedure over SDH
(LAPS), vitual concatenation (VCAT)
(G.707) standards
• Flexible data architecture options
(see Figure 2):
¬ Point-to point
¬ Hub and spoke
¬ Multipoint-to-multipoint
• Optical transport options within
OMSN products:
¬ Multiplex section protection (MSP):
1+1, 1+N
¬ Multiplex Section-Shared
Protection Ring (MS-SPRING) 2f
¬ Subnetwork Connection Protection
(SNCP) I/N
• Efficient network management with
dedicated Ethernet manager suite
To help meet service level agreements
(SLAs), each ISA-ES module allows serv-
ice providers and carrier operators to
specify per flow QoS. Traffic is specified
by a set of parameters to control its maxi-
mum and mean rates and the relative
burst window size in bytes (see Figure 3).
