Aggregation/broadband access

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

¬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):

•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

implementation, alarms retrieval and QoS Performance Monitoring (PM).

Figure 3. SLA support

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).
