Goal #2Demonstrate end-to-end slices across representative samples of the major substrates / technologies envisioned in GENI


Goals for this Meeting

• For each cluster answer:– How does a network device or aggregate

represent/reserve resources?– How do network slivers join to form an end-to-end

slice?

• Produce concrete examples, plans

Sliver Creation: Computation Resources (1 of 3)

1. Researcher submits credentials and request to aggregate manager (AM) for resources, that includes a reservation time

I want to reserve all the pieces to

build my experiment, I will start with

a CPU cluster, reserving the following• 300 Processors• 10 TB Local storage (multiple disks)• 1 GbE and 10 GbE link capacity

from network interface to CPU’s and 10TB drive

• CPU utilization measurement w/ data transfer rates

2. CM checks policies against credentials and accepts reservation by returning signed RSpec to User (called a ticket).

A similar set of actions are performed for the other CPU cluster and storage array

3b. AM sends copy of ticket to Slice Registry (who tracks resources in each slice).

At this stage, the researcher has a right to use specific resources (i.e., establish slivers) from several of the aggregates. However, these resources are not active and have not been composed into a coherent experiment.

Now that my edge processor resources are reserved, I need to establish data link connections across the multiple network domains. But, how do I set-up connections between two aggregates? Compute Cluster Storage

Aggregate Manager

When the AM issues a ticket, the signed Rspec will contain interconnection parameters of each network reservation, e.g., port number, VLAN ID, source Ethernet address, so the OB AM can associate network resources in PC to those in OB.

Aggregate Manager

The reservation specifies network bandwidth between the 3 components and Optical Backbone. The Processing Center AM handles establishing requested internal network configuration. Connectivity to OB already exists.

Optical Transport

At this stage, the researcher has obtained payload mapping information from each of the aggregate managers. No connections have been established

Optical Backbone Measurement

This is repeated for the Regional Research, Storage Server , Optical Edge (and Metro Wireless) networks.

Now that aggregate interconnection

mapping is established, I want to reserve

the following resources:• Optical multipoint topology from

storage server to PC,OE, RR network interfaces

• FPGA framers on linecards mapped to 10GbE payload at each aggregate interface

• 1 GbE link capacity between Processing center and other aggregate interfaces

• BER and OSNR measurements on all links

• Measurement data transfer rates

At this stage, a complete slice reservation exists. However, until that reservation is exercised (i.e., tickets redeemed), active slivers cannot be programmed.

Questions

• Is a standard method of describing network “coordinates” required?

• Does it go into the RSpec?• Are there now constraints on the order in which

networks can be added to a slice?• How does work with multiple networks in series?• How are ordering constraints handled in the

control framework?• How are tunnels (i.e., non-adjacent resources)

handled?


Today’s Agenda (ready to bash…)


Ground rules for today

• Spiral 1 focus (i.e., by this fall)• Different answers are OK for different clusters• Shared responsibility between control framework

& aggregate projects is required to solve this• This is an engineering, not research, discussion
