HP A8802 Router Chassis
The HP A8800 routers series feature a distributed high-performance network processor (NP) as well as high-capacity crossbar nonblocking switching technology that delivers robust network processing performance and flexibility. A distributed quality of service (QoS) control unit provides end-to-end service, as well as core services at a fine granularity. Furthermore, the routers' distributed operation, administration, and maintenance detection engines implement fault detection within 30 ms to provide uninterrupted core services. These innovative technologies, paired with the QoS control mechanism, provide smooth operation of multiple users and multiple services. The A8800 routers are commonly deployed in IP backbone networks, IP metropolitan area networks (MANs), or the core or convergence layers of large IP networks. Offering high forwarding performance and abundant services, A8800 series routers can capably fulfill user needs in a range of networking scenarios.
Quality of Service (QoS)
• Hierarchical QoS (HQoS): provides a built-in QoS engine that supports hierarchical QoS (HQoS) and can implement a hierarchical scheduling mechanism based on ports, user groups, users, and user services; also cooperates with MPLS TE to implement bandwidth reservation and scheduling based on tunnels and services
Management
• Management interface control: provides management access through modem port, terminal interface, as well as in-band and out-of-band Ethernet ports; provides access through terminal interface, telnet, or SSH
Connectivity
• High port density: provides up to 12 interface module slots, up to 96 OC3 POS ports, or 240 Gigabit Ethernet ports (fiber or copper) per A8812 system
Performance
• Industry-leading performance: provides switching capacity up to 1440 Gbps and forwarding performance up to 864 Mpps
Resiliency and high availability
• Separate data and control plane: separate data and control plane provide continual services
Layer 2 switching
• VLANs: support up to 4096 port or IEEE 802.1Q-based VLANs
Layer 3 services
• Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network
