Cisco ASR 1000 series routing processor Product overview
The Cisco ASR 1000 series routing processors can meet the routing requirements of the operator level IP and the multi protocol label switching (MPLS) packet infrastructure, which not only provide advanced routing functions, but also monitor and manage the first generation Cisco ASR 1000 series routing of other components in the Cisco ASR 1000 series aggregation service router The processor 1 (RP1; component number ASR1000-RP1) and the second generation Cisco ASR 1000 series routing processor 2 (RP2; component number ASR1000-RP2) (Figure 1) provide the following embedded functions:
To fully integrate industry-leading Cisco IOS software functions and services
Cisco ASR 1000 series is run by modularized Cisco IOS XE software.
High availability solutions for the most compact and fully redundant industry in the industry, providing optional redundant processor support and dual Cisco IOS software support for single routing processor solutions to improve network recovery, improve management and control costs
Provide hard disk drive (HDD) for code storage, boot, configuration, logging and so on.
Provide USB port to implement 1 GB Flash support
Provides built-in embedded USB (eUSB) memory support (ASR1000-RP1 is 1GB; the built-in RP1 on Cisco ASR 1002 routers is 8 GB) (partitions: 1 GB for boot flash; 7 GB for mass storage)
Provide on-site replacement and hot swap functions to minimize service interruption.
Provide Stratum-3 clock circuit, building integrated timing (BITS) input and output (only ASR1000- RP2 provides BITS output).
Provide memory extensions, Cisco ASR 1000 series routing processor 1 can be extended to 4-GB DRAM, Cisco ASR 1000 series routing processor 2 can be extended to 16GB DRAM
Functions And Advantages Of Cisco Asr1002
Because of the advanced functions in the Cisco ASR 1000 series routing processor, many other functions can be performed according to routing, including:
Establish and distribute forwarding information to Cisco ASR 1000 series embedded service processor (ESP).
Implementation of session boundary controller (SBC) setup and disassembly, and session strategy for voice streaming and video streaming applications, respectively.
To configure and distribute to the ESP forwarding engine for the status firewall policy.
Negotiation and maintenance of IP security (IPsec 1) authentication, encryption methods and encryption keys (Internet Key Exchange [IKE])
As the management processor of Cisco ASR 1000 Series Router, Cisco ASR 1000 series routing processor can automatically perform the following system management functions:
* loading the operating system software system images to all installed line cards according to the power on or operator commands.
State condition of synchronous redundant Cisco IOS XE software, routing processor and embedded service processor component.
* no interruption switch for redundant solution execution.
Provide the external system console and auxiliary ports, USB and Ethernet ports for router configuration and maintenance.
If there is a catastrophic Cisco IOS software failure, the system can be accessed directly through the kernel of the operating system.
Monitoring and managing the temperature of power and system components such as circuit cards, power supplies and fans.
