Enabling Active Networks Services on A Gigabit Routing Switch 7 The ORE Programmability • ORE: an Oplet Runtime Environment for injecting customized software into network – an open platform for secure downloading, installation, and safe execution of Java code – provide user-level service API – network services implemented using Java code
- 8. Enabling Active Networks Services on A Gigabit Routing Switch 8 The ORE Programmability • Oplet: a self-contained downloadable unit – encapsulates one or more services – contains service attributes such as dependency – Secure downloading, service installation • Service: a downloadable code that implements a specific functionality – includes Active Networks services: EE – Can be built on the top of other services – examples: filtering packet, altering forwarding priority and diverting packets

- 10. Enabling Active Networks Services on A Gigabit Routing Switch 10 ORE Services • Three categories – Standard: ORE-specific APIs for customer service encapsulation and management – System: low-level or underlying access APIs such as packet forwarding and processing services – Customized: user-level service APIs • Function: ORE or user services for common use • Oplets: application-specific customer services
- 11. Enabling Active Networks Services on A Gigabit Routing Switch 11 ORE Services • System Services – JFWD: Java Forwarding API, see next slide – JMIB: platform MIB access, provides access to hardware instrumentation – JPCAP: packet capturing, provides use of local Berkeley libpcap
- 12. Enabling Active Networks Services on A Gigabit Routing Switch 12 ORE Services • JFWD: a system service – Java Forwarding API, platform-independent – controls packet processing and forwarding – provides access to the hardware instrumentation – typical network mappings • IP filters: drop, forward and capture packets • IP routing • MAC address, ARP and Vlan – native implementation on Accelar and Linux
- 13. Enabling Active Networks Services on A Gigabit Routing Switch 13 ORE Services • Standard Services – OpletService: Oplet service API, extended to define service descriptions and interfaces – ManifestOplet: Oplet encapsulation abstract interface, implemented to create service-specific oplets – Start: ORE startup service, loads given services at startup – Shell: telnet-like user interface, provides shell commands to manipulate oplets and start or stop network services – Logger: ORE log service, provides runtime logs
- 14. Enabling Active Networks Services on A Gigabit Routing Switch 14 ORE Services • Customized services – HTTP: HTTP service – Jcapture: packet capturing service – IpPacket: IP packet utility, constructs IP/TCP/UDP header and payload – JMIB: platform MIB access, provides access to hardware instrumentation – JPCAP: packet capturing, provides use of local Berkeley libpcap
- 15. Enabling Active Networks Services on A Gigabit Routing Switch 15 Customer Service Deployment • Customer service programming – regular Java programming – two ORE APIs: OpletService and ManifestOplet • Service code packed in jar and stored in downloading servers • ORE downloads service code and starts particular services as instructed • A service can be built using other services
- 16. Enabling Active Networks Services on A Gigabit Routing Switch 16 Customer Deployment: ORE API • OpletService: the ORE base service – Extended by customer service interface classes to define service description and interfaces – customers also provide the service implementation classes to implement those interface classes – service implementation classes should include two additional private methods for starting and stopping the service function respectively
- 17. Enabling Active Networks Services on A Gigabit Routing Switch 17 Customer Deployment: ORE API • ManifestOplet: the abstract oplet interface – implemented by customers as concrete oplets to encapsulate the service code – has two methods startService() and stopService() to register or deregister a service at runtime – accompanied by manifest files to cover service information, e.g., oplet name, service description, dependency and package name
- 18. Enabling Active Networks Services on A Gigabit Routing Switch 18 Customer Deployment: package • What are includes in a service package? – Hello.class: the service interface class, extends OpletService – HelloImpl.class: the service implementation class, implements the interface Hello – HelloOplet.class: the Oplet class, implements Manifest and encapsulate service Hello – HelloOplet.mf: the service manifest file, provides the service information
- 19. Enabling Active Networks Services on A Gigabit Routing Switch 19 Customer Deployment: start • How to start customer services? 2 ways at least – at startup • the ORE startup service (start) starts those services specified in “start.properties”, which is in the same directory of the service package “start.jar” • edit “start.properties” to add or remove your service packages – at runtime • customers can use the ORE shell service to manipulate those services by “telnet OREHOST 1999” • the whole service lifecycle can be instructed – through the ORE API by remote applications
- 20. Enabling Active Networks Services on A Gigabit Routing Switch 20 Customer Deployment: To Accelar • Injecting customer services onto the Accelar – service code (i.e., jars) stored in external servers for downloading – services can be activated at startup or runtime – once activation successfully, those services work like native services on the Accelar
- 21. Enabling Active Networks Services on A Gigabit Routing Switch 21 ORE ANTS on the Accelar • Deploying the ANTS on the Accelar using ORE • MIT ANTS distribution – version 1.2 – no modification to the ANTS code • on the Accelar 1100B routing switch – ORE version 0.3.3 – ORE ANTS package – URL: “http://www.openetlab.org/downloads/” • An Active Networks service implementation
- 22. Enabling Active Networks Services on A Gigabit Routing Switch 22 ORE ANTS: service • Service: “AntsNodeService” – wrapping the MIT ANTS code – package “com.nortelnetworks.ore.service.ants” • AntsNodeService.class: the AntsNodeService interface • AntsNodeServiceImpl.class: the service implementation • AntsNodeOplet.class: the Oplet • AntsNode.mf: the manifest – service interfaces • getNode(): connect to the ANTS code • getConfiguration(): set up the service using ANTS configuration
- 23. Enabling Active Networks Services on A Gigabit Routing Switch 23 The ANTS Ping (Aping) Test • The ORE ANTS service tested by APing – an experimental active net built within Nortel – Accelar 1100B: the active router with ORE ANTS – Sun workstations 1: destination active node with MIT ANTS – Sun workstations 2: source active node with MIT ANTS (and APing) – Linux PC: the HTTP server providing the ORE service jar packages and the ORE ANTS configuration

- 25. Enabling Active Networks Services on A Gigabit Routing Switch 25 Summary • ORE brings the programmability to network • The ORE ANTS deployment on the Accelar is a successful instance of injecting Active Networks (AN) services to network nodes • Porting AN services to ORE is rather easy • If necessary, JFWD or other system services are used by customers to access underlying resource or hardware instrumentation • Accelar is still working on strong CPU competence & flexible ASIC programmability
