TRICONEX 3721C Communication module

Traffic filtering • ACLs to filter out unwanted traffic including denial of service (DoS) attacks; flow based filtering in hardware (layer 1 to layer 4) Converged networks (QoS) • Priority queues: Eight hardware-based queues per port for flexible QoS management • Traffic prioritization: Flow-based QoS with internal and external prioritization (also known as re-marking) • Bandwidth management: Flow-based bandwidth management, ingress rate limiting and egress rate shaping per port • Queue management with configurable scheduling algorithm: Strict Priority Queuing (SPQ), Weighted Round Robin (WRR) and Deficit Round Robin (DRR) • Congestion avoidance: Support for Endto-End Head-of-Line (E2E-HOL) blocking prevention and flow control • LLDP network polices for dynamic designation of VLAN-ID and layer-2/ layer-3 priority for IP phones • Auto-QoS for switch management traffic as well as traffic from Alcatel-Lucent IP phones • Fluent network for Voice and Video: Session Initiation Protocol (SIP) detection, monitoring and tracking. SIP profile for QoS, real-time conversation quality information concerning packet loss, jitter, MOS score and R-Factor.

IPv4 routing

 • Multiple VRF for network segmentation and Inter-VRF route leaking • Static routing, Routing Information Protocol (RIP) v1 and v2 • Open Shortest Path First (OSPF) v2, Intermediate System-to-Intermediate System (IS-IS), Border Gateway Protocol (BGP) v4 • Generic Routing Encapsulation (GRE) tunneling • Graceful restart extensions for OSPF and BGP • VRRP v2 • DHCP relay (including generic UDP relay) • ARP • IP SLA measurement • IP router port

IPv6 routing

 • Static routing • Routing Information Protocol Next Generation (RIPng) • OSPF v3 • BGP v4 (with extensions to IPv6 routing) • Graceful restart extensions for OSPF and BGP • VRRP v3 • Neighbor Discovery Protocol (NDP) IPv4/IPv6 multicast • Internet Group Management Protocol (IGMP) v1/v2/v3 snooping for optimized multicast traffic • Protocol Independent Multicast - SparseMode (PIM-SM)/Protocol Independent Multicast - Dense-Mode (PIM-DM) • Distance Vector Multicast Routing Protocol (DVMRP) • Multicast Listener Discovery (MLD) v1/v2 snooping for optimized multicast traffic
