MaintenanceMaintenance agreement with line operator, in case of major failure
24hrs to restore connectivity.
Failures may result from:a) improper installationb) material defects c) Force Majeured) others (aging... ?)
They are repaired by the specialized company and are paid respectively by:a) installing companyb) cable manufacturerc) PSNCd) PSNC....?
Monitoring infrastructure is being developed...
Link optimization
• a side effect of an urgent demand for DCM module ;-)• replacement of G.652 fiber with G.655 fiber (NZDS)• cost reduction via:
• lower # of regenerators, • lower # of DCF modules
But:• higher fiber costand• optimisation is valid for selected cases only and is
wavelength/waveset/link dependent.

Cost approximately 90KEuro, cost savings (equipment only): 35%
Network problems
Some problems appeared during installation:
– few faulty modules (1 DCM, 1 AMP, 2WCMs) instantly replaced on-spot
– on a stretched link the devices report transmission errors, which are corrected by FEC mechanism (working on 82km with 80km interface ;-) ). This is assymetric (one way) only. Problem can be fixed by additional regenerator.
No significant network problems noticed during the network operation.
New network services
ATM transport in 10GE network– continuation of former ATM network (still many customers
connected with ATM)– concatenation of Juniper CCC with 10GE 802.1p VLANs– service in the deployment/testing phase– approx. 20 connections between 5 MANs
New network servicesBandwidth on demand• establishes channels with given QoS between edge nodes of
backbone network• bases on VLAN and 802.1p technology• tagged VLANs in QoS profiles (profiles globally defined).• own topology database (defined by operator) and presented in
GUI (there is no topology discovery yet)• automatic (BFS) or manual VLAN path setup• all decision based on configuration information gathered from
switches (via SNMP and telnet)

New software
• Mulitcast monitoring
• Trouble Ticket system
• Network Inventory
• MCast6
Multicast monitoring (MUVI)
• Multicast network topology discovery• Network connections and routers availability monitoring• Event messages• Statistics• MIB browser• Multicast groups traffic visualisation
Contacts: Radosław Krzywaniahttp://[email protected]
Trouble Ticket system
• web interface • problem groups• two types of tickets:
– trouble ticket – information ticket
• the ticket life cycle:OPEN – [UPDATED] - CLOSED (CANCELED)
Trouble Ticket System was built on the basis of the Joshua PortalFramework (designed and realized in Java technology in PSNC).

MCast6Multimedia streaming aaplication with IPv4-IPv6 and
unicast/multicast gateway- client/server- distributed architecture with remote components- support for a number of streaming servers- client: multimedia streaming player- server: web-based application composed of: access, AA,
gateway, server management plug-ins, etc.- own JMF-based streaming server- wrapper for IceCast streaming server- on-demand feature
MCast6 – future work
• implementation of RTSP protocol• distributed content management• dynamic timetable of streaming sessions (SAP/SDP)• new wrappers, e.g. for Videolan• streaming sessions capture module
