CanWest filing for bankruptcy protection
CJOB News Team reporting
10/6/2009

CanWest Global Communications will seek court protection under the Companies' Creditors Arrangement Act.

The financially beleaguered Winnipeg-based company has been struggling under a mountain of debt for some time... and will file for creditor protection under a deal with a key group of creditors as it seeks Canadian court approvals for a restructuring.

Among the company's assets filing for creditor protection are Global Television, a number of other tv properties and the National Post.

CanWest has been selling pieces of its business in recent weeks to show lenders that it's making progress on reworking its operations.

Everything You Wanted to know about Dynamic Routing ..... Well Almost.

Everything You Wanted to know about Dynamic Routing ..... Well Almost.

• Variable-length subnet masking (VLSM):...ex: subnet mask of 255.255.255.252, which
  allows only two valid IP addresses...
• Only classless routing protocols support VLSM. To say that a routing protocol is classless is to say that it supports VLSM, and vice versa.
• ISPs use BGP today to exchange routing information between themselves and other ISPs and customers.
• BGP includes the ASNs in the routing updates to prevent loops.
• An autonomous system (AS) is a group of devices under the control of a single organization .
• Distance vector protocols advertise routing information by sending messages, called routing updates, out the interfaces on a router.
• Routers add directly connected subnets to their routing tables, even without a routing
  protocol.
• Routers send routing updates out their interfaces to advertise the routes that this router already knows. These routes include directly connected routes as well as routes learned from other routers.
• Routers listen for routing updates from their neighbors so that they can learn new routes.
• The routing information includes the subnet number and a metric. The metric defines
  how good the route is; lower metric routes are considered better routes.
• When possible, routers use broadcasts or multicasts to send routing updates. By using a broadcast or multicast packet, all neighbors on a LAN can receive the same routing
  information in a single update.
• If a router learns multiple routes to the same subnet, the router chooses the best route
  based on the metric. (If the metrics tie, there are a variety of options, "OSPF and EIGRP Concepts and Configuration,"
• Routers send periodic full updates and expect to receive periodic updates from
  neighboring routers.
• Failure to receive updates from a neighbor in a timely manner results in the removal of
  the routes previously learned from that neighbor.
• A router assumes that, for a route advertised by Router X, the next-hop router in that
  route is Router X.

The most obvious difference between RIP-1 and IGRP is the metric.

The largest difference between the two is that distance vector protocols advertise sparse
information; in fact, distance vector protocols know only that other routers exist if the other router broadcasts a routing update to them. When a distance vector protocol in a router hears a routing update, the update says nothing about the routers beyond that neighboring router that sent the update. Conversely, link-state protocols advertise a large amount of topological information about the network, and the routers perform some CPU-intensive computation on the topological data. They even discover their neighbors before bothering to exchange routing information.

 A router does not send routing information with OSPF until it discovers other OSPF-speaking routers on a common subnet. The following list gives you some idea of the process:

1. Each router discovers its neighbors on each interface. The list of neighbors is kept in a
   neighbor table.
2. Each router uses a reliable protocol to exchange topology information with its
   neighbors.
3. Each router places the learned topology information into its topology database.
4. Each router runs the SPF algorithm against its own topology database to calculate the
   best routes to each subnet in the database.
5. Each router places the best route to each subnet into the IP routing table.

• A router running a link-state protocol uses more memory and more processing cycles than do distance vector protocols.
• OSPF uses a concept called cost for the metric.

 OSI defines a network layer protocol called the connectionless Network Protocol (CLNP). It also defines a routing protocol-a routing protocol used to advertise CLNP routes, called Intermediate System-to-Intermediate System (IS-IS). IS-IS advertises CLNP routes between "intermediate systems," which is what OSI calls routers.

 Later in life, IS-IS was updated to include the capability to advertise IP routes as well as
CLNP routes. To distinguish it from the older IS-IS, this new updated IS-IS is called
Integrated IS-IS. The word integrated identifies the fact that the routing protocol can
exchange routing information for multiple Layer 3 routed protocols.

EIGRP does not use distance vector or link-state logic.

EIGRP (Balanced hybrid protocal)

The internal workings of EIGRP depend on an algorithm called the Diffusing Update

Algorithm (DUAL). DUAL exchanges more topology information than a distance vector

routing protocol, but it does not transmit full topology information like a link-state protocol.

Also, the computations used by DUAL require far less processing than the computation intensive

Dijkstra SPF algorithm

DUAL defines a method for each router not only to calculate the best current route to each

subnet, but also to calculate alternative routes that could be used if the current route fails.

An alternative route, using what DUAL calls a feasible successor route, is guaranteed to be

loop-free. So, if the current best route fails, the router immediately can start using the feasible

successor route instead so that convergence can happen very quickly.

• Like OSPF and Integrated IS-IS, it converges quickly, often in less than 3 seconds after a
  failure is recognized.
• Like OSPF, EIGRP discovers neighbors before sending them routing information.
• Like RIP and IGRP, EIGRP requires very little design effort. (Link-state protocols require
  some design work in medium to larger networks).
• Like IGRP, EIGRP is Cisco proprietary.
• Like IGRP, EIGRP uses a metric based on bandwidth and delay. EIGRP uses the same
  metric as IGRP, except that EIGRP scales the metric by multiplying by 256.
• Like link-state protocols, EIGRP does not send full updates on a periodic interval, but
  rather sends partial updates only as links or routers go up and down.
• Like link-state protocols, EIGRP builds some topology tables in addition to the IP routing table.

Winnipeg: You might die here ...

Written by John Bain

Beware my friend the shit winds are a'comen!

For anyone who has had their head under a rock you might wanna lissen up. The quiet city of Friendly Manitoba Winnipeg is now only a memory. Gangs ruling the inner quadrant with fear and indiscriminant violence. I can't post links to every gleaming shit-vent that has happened but I will list the last 4 that have hopefully opened the eye's to the shitpeg we now live in.

"A Winnipeg woman is facing charges of abduction and attempted murder after a 14-month-old girl was allegedly seen being beaten in the street.

"Witness told police he saw a woman beating a baby's head against the pavement in a neighborhood"

"I saw a woman there, holding her baby around the neck and smashing it into the cement, the baby's face. And it had something tied around its neck,"

"The baby's grandmother has said the girl was kidnapped the night of the attack."

"Local residents told CTV's Jill Macyshon that the girl's mother returned home early Tuesday morning to discover that someone had taken her child."

"Police say 19-year-old Nikita Solange Eaglestick has been charged with abduction, aggravated assault and attempted murder."

In an interview with USA Today, director Jon Favreau revealed that the sequel is set six months after the events of Iron Man, and stated that Stark's revealing of his identity is taking its toll on him. Favreau also discussed their version of Iron Man's comic book nemesis the Mandarin, and how it "allows us to incorporate the whole pantheon of villains". He also mentioned that S.H.I.E.L.D. will continue to have a major role.^[1]

During development, Favreau said the film would explore Stark's alcoholism, but it would not be "the Demon in a Bottle version".^[1] Downey said, while promoting the first film, that Stark (Robert Downey, Jr.) would probably develop a drinking problem as he is unable to cope with his age, as well as Pepper (Gwyneth Paltrow) getting a boyfriend.^[2] Before filming began, Downey revealed that while the film was not an adaptation of the Demon in a Bottle storyline from the comic book series, it was more about the "interim space" between the origin and theDemon story arc.^[3]
