NETWORK ENGINEER

Networks topology: ring topology, star and mesh topology topology.

• Advanced Services: Virtual Private LAN Services (VPLS), Virtual Private Wire Services (VPWS’s), Virtual Private Routed Networks (VPRN’s) based on RFC 4364 and IPv6 based services
• Service Tunneling: Enable layer 2 and layer 3 services on a single platform with the flexibility of any service over any port over a wide range of interfaces including DS3/E3, Ethernet, SONET/SDH PoS, frame relay and ATM interfaces. Additional interface options include OC-3/STM-1 support on the Any Service Any Port (ASAP) interface card and a combination interface card supporting Gigabit and 10 Gigabit ports.
• Multi-service edge: Comprehensive service continuity with FR/ATM/Ethernet pseudowire services (VPWS), Ethernet/FR/ATM service interworking, Ethernet, FR and ATM access to VPLS, IP-VPN and Internet services with service aware quality of service (QoS) to maintain stringent service level agreements (SLAs) and ensure a seamless migration to emerging services.
• Quality of Service (QoS): Service-based quality of service (QoS) allows for service-based queuing, which enables shaping, policing and marking of different traffic flows on a per service basis. Enhancements include class based forwarding allowing service packets to be directed over specific RSVP LSPs based on their forwarding class and LDP over RSVP-TE allows end to end LDP tunnels to inherit RSVP traffic engineering properties.
• Hierarchical Quality of Service (H-QoS): Hierarchical QoS uses an advanced scheduling mechanism, with multiple levels and instances of queuing, shaping, policing and marking, to prioritize different services over the same connection and combine all services into overall SLA
• Service Scaling: Concurrently supports tens of thousands of layer 2 and layer 3 services, more than 2M border gateway protocol (BGP) routes and up to 32K label switched paths (LSPs) per system. Enhancements include PW switching to scale VPWS and VPLS services over multi-area networks and LDP over RSVP-TE to avoid a full mesh of end-to-end RSVP-TE tunnels between PE routers
• High Availability: Non-stop services and non-stop routing that provide unparalleled availability and reliability. Non-stop services ensure that VPLS-based services and VPRNs are not affected when there is a CPM switchover on the Alcatel-Lucent 7750 SR. With non-stop routing, LDP adjacencies, sessions and the database remain intact if there is a switchover. Other differentiating high availability features include multi-chassis LAG and PW redundancy
• OAM: Unmatched service-aware operations, administration and maintenance (OAM) toolkit and mirroring - service assurance capabilities needed to reduce mean-time-to-repair (MTTR) and ensure a predictable end-user experience
• Enhanced troubleshooting tools: In-service software upgrade (ISSU) minimizes downtime between minor release upgrades. Service Assurance Agent (SAA), which consists of OAM and debugging tools that allow network operators to collect statistics such as loss, jitter, latency, response time and packet loss. Multicast troubleshooting tools includes a full set of troubleshooting tools for multicast that allow network operators to assess the distribution of IP multicast traffic, to trace multicast paths in the network and to calculate performance metrics of the network.
• Security: CPM-queuing eliminates the effect of one peer consuming the system resources and service-based filtering uses access control lists (ACLs) to filter on a per service or per interface basis
• Accounting and Billing: Service-based accounting and billing collects statistics on a per service basis, not just a per port basis
• Network Management: The Alcatel-Lucent 7750 SR is fully supported by the Alcatel-Lucent 5620 Service Access Manager which simplifies the provisioning, management and troubleshooting of IP/MPLS networks
